The Importance Of The Cardiovascular System

William Li mentions the blood vessels in his talk. Human’s body is literally packed with them. The smallest blood vessels are called capillaries, it is the vessels of life and are feeding cancer cells, bringing oxygen and nutrients. Also, it can be the vessels of death. We have got nineteen million of them in our bodies. Blood vessels are adapt our bodies no matter where they grow in our bodies.

The cardiovascular system, which consists of the heart and blood vessels, is the circulatory systems in our body. The major function of the system is transportation; the heart is the system pump and the blood vessels are the delivery routes. The heart transport respiratory gases, nutrients, wastes, and other substances vital to the body’s homeostasis to and from the cells by using the blood as a medium.

Our cardiovascular system is composed of the heart and blood vessels. The main purpose of this system is to transport substances throughout the body. Even though transportation is the main function of the cardiovascular system, it is not the only function. Along with transportation we have protection and regulation.

The body needs to circulate glucose and oxygen rich blood to the cells within the body and remove carbon dioxide waste from the muscle. This role is specifically dedicated to the cardiovascular system. The heart, veins, arteries and capillaries make up the cardiovascular system.

Composed of the heart, blood vessels, and blood, the cardiovascular system is the body system that carries out the tasks of pumping and transporting blood, oxygen, nutrients, and waste products, and other substances throughout the body.

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

Cardiovascular system contains the heart, arteries, blood and blood vessels, every system has a function and the function of cardiovascular system is that it is there to transport oxygen, nutrients, hormones and waste products around the human body. The cardiovascular system would start to slow down as the

The main function of the cardiovascular system in relation to energy is to transport the oxygen and glucose to the cells, and to transport the waste products such as carbon dioxide and urea (waste product from protein digestion) away from the cells and to the lungs or kidneys.

Arteries: Carry blood away from the heart and supplies blood to the tissues of the body. There are several types.

Arteries carry blood away from the heart and are the largest of the blood vessels. Arteries are the largest and most muscular because of their function. They carry oxygenated blood away from the heart and therefore has force placed on them as the heart contracts and pumps. Veins carry blood back to the heart and lungs to be oxygenated again. The walls of veins are thin, elastic, and the flow of blood through veins are much slower and rely on surrounding muscles to push blood back to the heart. (They also have valves to prevent the backflow of

Both the arterial system and venule system play a key role within the circulatory system, but this is possible because of their differences. An artery will pump blood away from the heart at high pressure, due to its think walls and small/round lumen. Arteries also possess numerous amount of that allows it to stretch. A vein will pump blood away from the heart at low pressure, while acting against gravity, due to its thin walls, multiple valves, and large size and irregular shaped lumen. Arteries contains vasa vasorum and nervi vasorum on its tunica externa, while the veins possess them on both the tunica externa and tunica media.

The cardiovascular systems function is to pass blood through ones body keeping their muscles oxygenated, to keep nutrients that are needed in the body and to help get rid of metabolic waste. The cardiovascular system is made up of three components, these are; the heart, the blood and the blood vessels.

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 cardiovascular system is, without a doubt, one of the most important systems in the body. It regulates your body temperature, maintains fluid balance, protects from infection and blood loss, and transports nutrients, gases, and waste products around the body. Every time you

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
