The Cardiovascular System : The Circulatory System

system where the heart is the pump, which pumps the blood, and the blood vessels are

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.

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 heart, blood and blood vessels make up the basis of the cardiovascular system also known as the circulatory system. The average human body contains approximately 5 litres of blood which is carried around the body via a network of blood vessels split into three types; arteries, veins and capillaries. The arteries are the largest of the three vessels and carry blood away from the heart. Veins carry blood to the heart and are smaller than arteries, then finally the smallest vessels known as capillaries distribute the oxygen rich blood to organs whilst simultaneously picking up the waste carbon dioxide and water from the organs to transport back to the heart where it can be pumped into the lungs to be exhaled.

The circulation of blood allows for the transport of nutrients, gases, blood cells and hormones for immunological defense, nutrition, as well as temperature, pH and homeostatic maintenance. The heart muscle circulates blood, a fluid containing erythrocytes, leukocytes platelets and plasma. Since humans have a closed cardiovascular system, gases and nutrients diffuse across blood vessels into interstitial fluid, which then carry these essential components to various cells, while moving cellular waste products away. The arteries transport oxygenated blood from the left ventricle through the aortic semilunar valve. Circulation begins in the aorta, a large, arched, thickset artery that branches into major arteries of the trunk as well as arteries of the lower extremities below the diaphragm. Capillaries are a system of small blood vessels that transport blood to the venous system after distributing

The cardiovascular system - The cardiovascular system is responsible for transporting nutrients and removing gaseous waste from the body. It consists of the heart, which powers the whole process, the veins, arteries, and capillaries, which deliver oxygen to tissue at the cellular level. The cardiovascular system carries blood that is low in oxygen away from the heart to the lungs via arteries, where oxygen levels are restored through the air once oxygenated, this blood is then carried throughout the body via arteries, keeping our organs and tissue alive. The cardiovascular system is the workhorse of the body, continuously moving to push blood to the cells. If this important system ceases its work, the body dies.

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.

The cardiovascular system is a piece of the more extended circulatory system, which circles liquids all through the body .The circulatory system incorporates both the cardiovascular system and the lymphatic the system. The cardiovascular system moves blood all through the body and the lymphatic system moves lymph. Which is a reasonable liquid that is like the plasma in blood?

The cardiovascular system is made up of the heart, blood and blood vessels. Its function is to transport oxygen to all systems of the body. Oxygen is needed for the body systems to operate. Exercise increases the need for oxygen and causes the heart to pump faster. This in turn sends more blood through the vessels. The vessels leading from the heart are the arteries and the veins are the vessels that lead to the heart. Exercises causes the body to release a hormone called adrenalin. Adrenalin makes the blood vessels expand in order to allow more blood to flow through. The body also makes more capillaries. Capillaries transfer oxygen to body tissues. They collect waste and send it back through the veins to the heart. These new capillaries

The capillary exchange is where necessary gases and molecules move between the plasma and the interstitial fluid. Both hydrostatic pressure and osmotic pressure contribute to this, as they help fluids move in and out of capillaries and through diffusion. Arteries carry blood to the body organs and tissues, and once they reach an organ, branch into small branches called arterioles. These arterioles then branch into capillaries, thin-walled blood vessels, that due to their thin walls are best suited for the exchange of fluid, gases, nutrients, and waste between blood and body tissues. There are two ends of a capillary, arterial and venous. Large tubes known as venules gather blood from the capillaries to form veins. Veins are tubes that carry oxygen-depleted blood to the heart. Collectively, the hydrostatic pressure and osmotic pressure are significant because they

The circulatory/blood system contains erythrocytes (red blood cells), leukocytes (white blood cells), and platelets. It also contains plasma, bone marrow, the spleen, and the thymus. The main function of the erythrocytes (red blood cells) is to carry oxygen throughout the body. The main function of the leukocytes (white blood cells) is to fight infection. Platelets are also known as megakaryocytes. Platelets are mostly needed for the clotting process. Erythrocytes have about five million red blood cells per cubic millimeter of blood. Leukocytes have about four thousand eight hundred to ten thousand eight hundred white blood cells per cubic millimeter of blood. We have more red blood cells than we do white blood cells. Platelets have about one

veins to the tissues of the body. These walls do not let out blood but

After much consideration and time to process all of the organ systems in the human body, I feel as if the circulatory system is a significant key element in maintaining homeostasis in the human body. The circulatory system is a vast network of organs and vessels that is responsible for the flow of blood, nutrients, hormones, oxygen and other gases to and from cells. The circulatory system is an organ system that permits blood to circulate and transport nutrients (such as amino acids and electrolytes), oxygen, carbon dioxide, hormones, and blood cells to and from the cells in the body to provide nourishment and help in fighting diseases, stabilize temperature and pH, and maintain homeostasis. The cells that make up the circulatory system include red blood cells, white blood cells, platelets and plasma. These cells are all components of the blood in which the circulatory system acts as a highway for. The circulatory system has various types of tissue that are found throughout it, including epithelial tissue, muscle tissue, nervous tissue, and connective tissue. Epithelial tissue can be found in the structure of the arteries, veins, and capillaries, and it also covers the heart. The main organ of the circulatory system, the heart, is considered a muscle and therefore is largely made up of muscle tissue. The nervous tissue is made up of nerve cell fibers embedded in connective tissue. Nervous tissue is important to the circulatory system because it helps the brain to transmit
