What Are The Heart And Blood Vessels
Blood vessels form the living system of tubes that carry blood both to and from the heart. All cells in the body need oxygen and the vital nutrients found in blood. Without oxygen and these nutrients, the cells will die. The heart helps to provide oxygen and nutrients to the body’s tissues and organs by ensuring a rich supply of blood.
Not only do blood vessels carry oxygen and nutrients, they also transport carbon dioxide and waste products away from our cells. Carbon dioxide is passed out of the body by the lungs most of the other waste products are disposed of by the kidneys. Blood also transports heat around your body.
Anatomy of the heart and blood vessels
Introduction To The Major Blood Vessels Of The Heart:
The major blood vessels of the heart are the larger arteres and veins that attach to the atria and ventricles and transport blood to and from the
Blood is delivered to the right atrium from the systemic circulatory system by two veins:
- The superior vena cava transports oxygen-depleted blood from the upper extremities, head, and neck.

What Are Three Types Of Blood Vessels
There are three kinds of blood vessels: arteries, veins, and capillaries. Each of these plays a very specific role in the circulation process. Arteries carry oxygenated blood away from the heart. Theyre tough on the outside but they contain a smooth interior layer of epithelial cells that allows blood to flow easily.
What Are The Effects Of Vascular Disease
Because the functions of the blood vessels include supplying all organs and tissues of the body with oxygen and nutrients, removal of waste products, fluid balance, and other functions, conditions that affect the vascular system may affect the part of the body supplied by a particular vascular network, such as the coronary arteries of the heart.
Examples of the effects of vascular disease include:
-
Coronary artery disease. Heart attack, angina
-
Cerebrovascular disease. Stroke, transient ischemic attack
-
Peripheral arterial disease. Claudication , critical limb ischemia
-
Vascular disease of the great vessels. Aortic aneurysm , coarctation of the aorta , Takayasu arteritis
-
Thoracic vascular disease. Thoracic aortic aneurysm
-

What Makes The Heart Pump
Your heart has a special electrical system called the cardiac conduction system. This system controls the rate and rhythm of the heartbeat. With each heartbeat, an electrical signal travels from the top of the heart to the bottom. As the signal travels, it causes the heart to contract and pump blood.

The Heart And Blood Vessels
Oxygen is vital to life as it provides fuel for all the bodys functions. The hearts role is to pump oxygen-rich blood to every cell in the body. The blood vessels a network of interconnecting arteries, arterioles, capillaries, venules, and veins provide the pathway in which blood travels.
Arteries are the passageways through which the blood is delivered, the largest of which is the aorta. The aorta branches off the heart and divides into many smaller arteries, which have muscular walls that adjust their diameter to increase or decrease blood flow to a particular body area. Capillaries are thin walled, highly branched vessels that feed the tissues and collect wastes to be carried back to the lungs, liver, or kidney for elimination. Capillaries empty into the venules, which in turn drain into the veins that lead back to the heart. Veins carry deoxygenated blood to the lungs to pick up more oxygen, and then back to the heart once again.

How Does Blood Move Through The Heart
Blood comes into the right atrium from the body, moves into the right ventricle and is pushed into the pulmonary arteries in the lungs. After picking up oxygen, the blood travels back to the heart through the pulmonary veins into the left atrium, to the left ventricle and out to the bodys tissues through the aorta.
There are multiple functions going on in our bodies simultaneously. For smooth functioning and better coordination between organs, each work inside the body is differentiated so that the whole body works flawlessly.
One of the main functions of our body is the transportation of blood to and from the heart. There are two types of blood vessels arteries and veins in the circulatory system involved in carrying blood to the heart and away from the heart.
Arteries and veins, though they belong to the circulatory system, differs in their functionality and speciality. In this article, we will be looking at what exactly arteries and veins are and what are their significant differences.

Which Blood Vessels Carry Blood Away From The Heart
Explanation:
The ARTERIES are major blood vessels connected to your heart.
1. The pulmonary artery carries blood from the right side of the heart to the lungs to pick up a fresh supply of oxygen.
2. The aorta is the main artery that carries oxygen-rich blood from the left side of the heart to the body.3. The coronary arteries are the other important arteries attached to the heart. They carry oxygen-rich blood from the aorta to the heart muscle, which must have its own blood supply to function.
The VEINS also are major blood vessels connected to your heart.
1. The pulmonary veins carry oxygen-rich blood from the lungs to the left side of the heart so it can be pumped to the body.
2. The superior and inferior vena cavae are large veins that carry oxygen-poor blood from the body back to the heart.
What Do The Heart And Blood Vessels Do
The hearts main function is to pump blood around the body. Blood carries nutrients and waste products and is vital to life. One of the essential nutrients found in blood is oxygen.
The right side of the heart receives blood lacking oxygen from the body. After passing through the right atrium and right ventricle this blood is pumped to the lungs. Here blood picks up oxygen and loses another gas called carbon dioxide. Once through the lungs, the blood flows back to the left atrium. It then passes into the left ventricle and is pumped into the main artery supplying the body. Oxygenated blood is then carried though blood vessels to all the bodys tissues. Here oxygen and other nutrients pass into the cells where they are used to perform the bodys essential functions.
A blood vessels main function is to transport blood around the body. Blood vessels also play a role in controlling your blood pressure.
Blood vessels are found throughout the body. There are five main types of blood vessels: arteries, arterioles, capillaries, venules and veins.
Arteries carry blood away from the heart to other organs. They can vary in size. The largest arteries have special elastic fibres in their walls. This helps to complement the work of the heart, by squeezing blood along when heart muscle relaxes. Arteries also respond to signals from our nervous system, either tightening or relaxing .

How Does The Heart Beat
The heart gets messages from the body that tell it when to pump more or less blood depending on a person’s needs. For example, when we’re sleeping, it pumps just enough to provide for the lower amounts of oxygen needed by our bodies at rest. But when we’re exercising, the heart pumps faster so that our muscles get more oxygen and can work harder.
How the heart beats is controlled by a system of electrical signals in the heart. The sinus node is a small area of tissue in the wall of the right atrium. It sends out an electrical signal to start the contracting of the heart muscle. This node is called the pacemaker of the heart because it sets the rate of the heartbeat and causes the rest of the heart to contract in its rhythm.
These electrical impulses make the atria contract first. Then the impulses travel down to the atrioventricular node, which acts as a kind of relay station. From here, the electrical signal travels through the right and left ventricles, making them contract.
One complete heartbeat is made up of two phases:

How The Heart Works
The heart is an organ, about the size of a fist. It is made of muscle and pumps blood through the body. Blood is carried through the body in blood vessels, or tubes, called arteries and veins. The process of moving blood through the body is called circulation. Together, the heart and vessels make up the cardiovascular system.
Blood Vessels: Circulating The Blood
|
Blood travels from the heart in arteries, which branch into smaller and smaller vessels, eventually becoming arterioles. Arterioles connect with even smaller blood vessels called capillaries. Through the thin walls of the capillaries, oxygen and nutrients pass from blood into tissues, and waste products pass from tissues into blood. From the capillaries, blood passes into venules, then into veins to return to the heart. Arteries and arterioles have relatively thick muscular walls because blood pressure in them is high and because they must adjust their diameter to maintain blood pressure and to control blood flow. Veins and venules have much thinner, less muscular walls than arteries and arterioles, largely because the pressure in veins and venules is much lower. Veins may dilate to accommodate increased blood volume. |
If a blood vessel breaks, tears, or is cut, blood leaks out, causing bleeding. Blood may flow out of the body, as external bleeding, or it may flow into the spaces around organs or directly into organs, as internal bleeding.

Diseases Of Blood And Blood Vessels
The blood can be affected by trauma or diseases in other parts of the body leading to anaemia, a lack of red blood cells that reduces supply of oxygen to tissues, or polycythaemia, in which there are too many red blood cells. Also, there are cancers of blood cells like leukaemia.
Problems with blood vessels can also lead to high blood pressure, heart attack andstroke.
Which Artery Carries Blood Away From The Heart
Arteriesarteryheartcarryblood away from the heart
. People also ask, what type of artery carries blood away from the heart?
Arteries. Arteries carry blood away from the heart. Pulmonary arteries transport blood that has a low oxygen content from the right ventricle to the lungs. Systemic arteries transport oxygenated blood from the left ventricle to the body tissues.
Also Know, which vessel does not carry blood to the heart? The pulmonary arteries carry deoxygenated blood from the right ventricle into the alveolar capillaries of the lungs to unload carbon dioxide and take up oxygen. These are the only arteries that carry deoxygenated blood, and are considered arteries because they carry blood away from the heart.
Just so, which vessels carry oxygenated blood away from the heart?
Arteries carry oxygenated blood away from the heart to the tissues, except for pulmonary arteries, which carry blood to the lungs for oxygenation .
How does blood return to the heart?
The heart pumps blood to all parts of the body. Oxygen-poor blood returns from the body to the heart through the superior vena cava and inferior vena cava , the two main veins that bring blood back to the heart. The oxygen-poor blood enters the right atrium , or the right upper chamber of the heart.

Where Are The Heart And Blood Vessels Found
The heart is a fist-sized organ which lies within the chest behind the breastbone . The heart sits on the main muscle of breathing , which is found beneath the lungs. The heart is considered to have two ‘sides’ – the right side and the left side.
The heart has four chambers – an atrium and a ventricle on each side. The atria are both supplied by large blood vessels that bring blood to the heart . Atria have special valves that open into the ventricles. The ventricles also have valves but, in this case, they open into blood vessels. The walls of the heart chambers are made mainly of special heart muscle. The different sections of the heart have to squeeze in the correct order for the heart to pump blood efficiently with each heartbeat.
Classification & Structure Of Blood Vessels
Blood vessels are the channels or conduits through which blood is distributed to body tissues. The vessels make up two closed systems of tubes that begin and end at the heart. One system, the pulmonary vessels, transports blood from the right ventricle to the lungs and back to the left atrium. The other system, the systemic vessels, carries blood from the left ventricle to the tissues in all parts of the body and then returns the blood to the right atrium. Based on their structure and function, blood vessels are classified as either arteries, capillaries, or veins.

What Causes Vascular Disease
Causes of vascular disease include:
-
Atherosclerosis. Atherosclerosis is the most common cause of vascular disease. It is unknown exactly how atherosclerosis starts or what causes it. Atherosclerosis is a slow, progressive, vascular disease that may start as early as childhood. However, the disease has the potential to progress rapidly. It is generally characterized by the buildup of fatty deposits along the innermost layer of the arteries. If the disease process progresses, plaque may form. This thickening narrows the arteries and can decrease blood flow or completely block the flow of blood to organs and other body tissues and structures.
-
Blood clots. A blood vessel may be blocked by an embolus or a thrombus .
-
Inflammation. In general, inflammation of blood vessels is referred to as vasculitis, which includes a range of disorders. Inflammation may lead to narrowing and blockage of blood vessels.
-
Trauma or injury. Trauma or injury involving the blood vessels may lead to inflammation or infection, which can damage the blood vessels and lead to narrowing and blockage.
-
Genetic. Certain conditions of the vascular system are inherited.
