Difference Btw Artery And Veins Case Study

The artery’s purpose is to carry blood away from heart at high pressure. An artery is adapted for its role because the artery

The circulatory system which is present in the chest consists of heart and blood vessels such as arteries, veins and capillaries (Australian Indigenous Healthinfonet, 2016). The heart being the centre controls the blood circulation throughout the body receives deoxygenated blood through veins which is then converted into or replaced by the oxygenated blood from the lungs and then pumped out by the heart to different organs of the body through arteries. (Australian Indigenous Healthinfonet, 2016). The diseases that affects the normal function and structure of the circulatory system are called cardiovascular diseases (Australian Indigenous Healthinfonet, 2016). It commonly includes diseases such as stroke, coronary or ischaemic heart disease, peripheral vascular disease, heart failure, cardiomyopathy etc. that may be life-threatening ("Department of Health | Cardiovascular disease", 2016).

There are three main types of blood vessels: arteries, veins, and capillaries. Arteries are vessels that usually carry highly oxygenated blood away from the heart and to the rest of the body. (The pulmonary trunk and related arteries are exceptions, as they actually carry blood from the lungs toward the heart.) Because arteries must transport high volumes of blood being forcefully pumped out by the heart and must therefore withstand greater pressure, most have thick, muscular walls and are more flexible as well. Arterioles, smaller types of arteries with thinner walls, branch off of the arteries to carry blood to another type of vessel, called the capillary. Capillaries are the most abundant blood vessels in the body. Thinner and smaller than the other blood vessels, the role of capillaries is to exchange substances like water, gases, chemicals, nutrients, wastes, etc. with the tissues of the body. The third type of blood vessel is the vein. Although they are generally larger than the other blood vessels, veins tend to have thinner, less flexible walls, as they are not forced to deal with such high blood pressures. Venules (veins’ versions of arteries’ arterioles) connect the capillaries to the veins, which then transport blood back

The blood circulates around the body. The heart contract and relax, this mechanism of heart makes the blood to flow in the arteries to the body from heart and come back from body to heart through veins. The arteries carry oxygenated blood or oxygen rich blood and the veins carry deoxygenated blood or oxygen poor blood. This flow creates the pressure on the arterial wall and the pressure that is exerted on the arterial wall is known as blood pressure. Blood pressure is expressed by the

I found the differences between arteries and veins are their functions they provide to the heart as well as their structure. Arteries transfers blood away from the heart into the periphery resulting in the pressure of the blood in the arteries being high. Where as, the veins transfer blood towards the heart. Arteries carry oxygenated blood distributing it in the periphery as the pulmonary artery moves deoxygenated blood into the lungs for purification. The wall of an artery consists of three layers machining it thicker than veins. The elasticity within the layers of the muscle allows arteries to handle great pressures of blood within it. The thickest layer is known as tunica media as the other two are recognized as tunica externa, and tunica interna. The vein obtains blood from the periphery and carries it towards the heart. Veins are known to carry deoxygenated blood and transfers it the heart for purification. The pulmonary vein is known to carry oxygenated blood. However, there are semilunar valves found within the vein that does not allow retrograde flow of blood in preventing blood to flow in the opposite direction. Veins are thinner when compared to arteries consisting of thin elastic muscle layers with one thick layer being the tunica adventitia. Arteries consist of: carrying oxygenated blood expect for the pulmonary artery; deeply found in the body; thick walled and

ANSWER: The lymph vessels and the veins both have valves that are one way, and allow the blood to return to the heart. The valves looks like gateways for the blood flow (1 p. 372 and 399).

The lymphatic system is very similar, and works with and directly at the side of the cardiovascular system. The lymphatic system has a network of vessels like the circulatory system which pump a plasma-like fluid called lymph around it’s own lymph vessels, and are found in most other tissues of the body, except the central nervous system.

Arteries: carry blood away from heart; oxygenated except for pulmonary circulation and umbilical vessels of fetus

Blood is one of the most vital components of the human body. The blood carries many functions such as to supply oxygen to the bodies tissues, remove metabolic waste products, regulate our core temperature as well as fighting infection and foreign bodies (Glover, 1997). The cardiovascular system is composed of the heart and its vessels. The heart is an involuntary muscle which receives blood to the atrias, which is then pumped via the ventricles. The vessels are composed of three main types. Arteries, veins and capillaries; all which transport blood throughout the entirety of the body. The constant action of both the vessels and heart ensure that the body receives a continuous supply of blood, keeping us within our homeostatic limits.

The first main vessel that leaves the heart is the pulmonary artery and is the only artery that carries de-oxygenated blood and traveling through the lungs is then oxygenated and returned to the heart by the pulmonary vein and that is the only vein in the body to carry oxygenated blood. The now oxygenated blood leaves from the heart by the aorta and the splits to the carotid artery also known as the subclavian artery to the arms and the thoracic artery. The carotid artery leads to smaller arteries, arterioles and continuous capillaries around the arms and head and lead back to the heart first through the fenestrated capillaries, venule and medium sized veins and back to the largest vein that is called the jugular vein that is also known as

A healthy, normal heart has two strong pumps. One pump uses arteries to push blood with oxygen through the body and away from the heart. The other uses veins to bring blood back into the heart then the lungs to get more oxygen. The main blood supplier, the aorta, branches off into two of the main coronary arteries into smaller ones.

there is no pumping mechanism to do so); veins have to be able to hold

The arteries are thicker and more elastic because of the fast pumping of blood that leaves the heart to other organs to the body, as where the veins are small due to the low blood flow because of the slow movement from the capillaries to the veins not like the forceful pumping from the heart to the arteries to the rest of the body. The Oxygenated blood goes through the arteries except the pulmonary arteries. Then Deoxygenated blood goes through the veins except the pulmonary veins. The lumen of the artery is narrow, were as the lumen of the veins is wider. There are not valves in the arteries, were as the valves are present in veins. In the arteries, endothelial cells of tunica intima are more long then wider, and have more elastic membrane that is more developed. Then the Tunica media is more muscular, and the tunica extrema is not as developed. In veins, the endothelial cells of tunica intima are not as long and have more elastic membrane then being developed. The Tunica media is less muscular were the tunica extrema is more developed. Arteries are deep within and the veins are more superficial. Capillaries are microscopic vessels; they carry blood from the arterioles then go to the small veins or venules. The wall of the capillary made up of a
