Conclusion cardiovascular system essay

Along with providing oxygen to the muscle cells the blood, delivered from the heart, also takes away the carbon dioxide present in the muscle cells and at this point the blood becomes deoxygenated. The muscle are able to do their function when the blood provides the muscles with the nutrients and…. Two sides of the heart pump blood through two different circulations. Pulmonary circulation involves movement of blood from the right ventricles to the lungs.

Systemic circulation involves movement from the left ventricle, throughout the body. When the heart beats the atria contract first in atrial systole. When the ventricles fill with blood, they too contract together in ventricular systole. Left ventricle — forms the apex of the heart. Blood passes from the left ventricles through the aortic valve into the ascending….

This occurs when there is excess fluid in the plural cavity. The plural cavity is the thin, fluid filled space that surrounds the lungs and prevents friction rub and cushion. One of the main causes of pleural effusion is congestive heart failure.

This occurs as a result of an increase in pulmonary capillary pressure, which in turn increased the interstitial fluid in the lung. Most often the heart failure that causes pleural effusions are related to right side heart failure, but can also be bilateral failure.

The CO2 therefore diffuses into the blood cells and oxygen into the tissues. The blood full of CO2 returns to the lungs where it enters the capillaries in the lungs reaching the alveoli and the cycle repeats itself Pittman, The oxygenated blood is red in color while the deoxygenated purplish or pale in…. This type of situation is called coronary artery disease, or atherosclerosis means the hardening of the arteries in which fatty deposits build up inside the coronary arteries.

Heart attack, or againa occurs when a blood clot develops from plaque in one of the arteries. As the clot gets bigger, it becomes harder to supply blood and oxygen to the heart.

The cardiovascular system works closely with other systems in our bodies. It supplies oxygen and nutrients to our bodies by working in rhythm with the respiratory system. Simultaneously, the cardiovascular system helps carry waste and carbon dioxide out of the body. Hormones are produced by the endocrine system and are also transported through the blood in the circulatory system. When red blood cells pass by the lungs, the carbon dioxide that they are carrying diffuses into the lungs and in return, some oxygen diffuses into the red blood cells.

The red blood cells are then transported all throughout the body through the arteries and give nutrients to organs and tissues by using diffusion. Carbon dioxide from the organs and tissues diffuses into the red blood cells just as oxygen diffuses out of the red blood cells. The cells then carry the carbon dioxide back to the lungs where then diffusion occurs, and the cycle begins yet again.

Red blood cells also contain a substance called hemoglobin. Hemoglobin are small molecules found within red blood cells that give the blood its rich red color. Red blood cells are first produced in the bone marrow and then released into the bloodstream once they have matured. The lifespan of the cells is about three or four months, once they have aged or become damaged they are subsequently removed from the bloodstream by the spleen.

The most important job of the red blood cells is to transport oxygen and other nutrients to every of the part of the body and get rid of wastes in the body, such as carbon dioxide. Blood doping is a performance enhancing process and is frowned upon in athletic competitions worldwide.

It is when an athlete removes some of the blood from their body a few weeks prior to a large competition. During these weeks, their body replenishes the blood that they lost, and then just before the competition, they inject the blood back into their body, giving themselves an irregularly high level of red blood cells in the bloodstream.

The more red blood cells mean more oxygen, which in turn gives the athlete a higher endurance, and more stamina. Blood doping is a very dangerous and unsanitary process that will result in immediate disqualification from competition due to the fact that it gives an individual an advantage over the other competitors. Blood vessels help maintain a stable body temperature by manipulating the blood flow to the surface of the skin.

Several functions of the cardiovascular system can control blood pressure. Autonomic nerve signals from the brain along with certain hormones affect the rate and strength of heart contractions. Greater contractile force and heart rate will lead to an increase in blood pressure, which can also affect blood pressure. Vasoconstriction decreases the diameter of an artery by contracting the smooth muscle in the arterial wall.

The sympathetic division of the autonomic nervous system causes vasoconstriction, which leads to increases in blood pressure and decreases in blood flow in the constricted region. Vasodilation is the expansion of an artery as the smooth muscle in the arterial wall relaxes after the fight-or-flight response wears off or under the effect of certain hormones or chemicals in the blood. The volume of blood in the body also affects blood pressure.

A higher volume of blood in the body will raise the blood pressure by increasing the amount of blood pumped by each heartbeat. Thicker and more viscous blood from clotting disorders will also raise blood pressure. Hemostasis, the clotting of blood and formation of scabs, is managed by the platelets of the blood. Platelets normally remain inactive in the blood, that is until they reach damaged tissue or leak out of the blood vessels through a wound.

Once they are active, platelets change into a spiny ball shape and become very sticky in order to latch on to damaged tissues. Then they release chemical clotting factors and begin to produce the protein fibrin to act as structure for the blood clot. After which they also begin sticking together to form a platelet plug. The platelet plug will serve as a temporary seal to keep blood in the vessel and keep foreign material out of the vessel until the cells of the blood vessel can repair the damage to the vessel wall.

The left and right sides of the heart are divided by a muscular wall of tissue known as the septum of the heart. The right side of the heart receives deoxygenated blood from the systemic veins and pumps it into the lungs for oxygenation. The left side of the heart receives oxygenated blood originating from the lungs and pumps it through the systemic arteries to the tissues of the body.

Each heartbeat results in the simultaneous pumping of both sides of the heart, making the heart a very efficient pump. Thus making the cardiovascular system overall the most essential part of the body for a person to live. Essay Sauce, The cardiovascular system.
