The Function Of The Circulatory System

I am the Bob the heart. I am located just behind and slightly left of the breastbone. The system that works with me is the circulatory system. The circulatory system is an organ system that permits blood to circulate and transports nutrients, oxygen, carbon dioxide, hormones and blood cells. The circulatory system also helps forming cells in the body to nourish it and help fight diseases.

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 circulatory system and the respiratory system work closely together to ensure that organ tissues and systems receive enough oxygen. Oxygen is required for cellular functions such as cell respiration. This is so the body’s organs and cells can work at fully; it is done by releasing chemical energy with in stored foods. The air breathed in and held in the lungs is transferred to the blood. The blood is circulated by the heart, which pumps the oxygenated blood from the lungs to the body organs and returns with deoxygenated blood.

The respiratory system is a complex organ structure of the human body anatomy, and the primary purpose of this system is to supply the blood with oxygen in order for the blood vessels to carry the precious gaseous element to all parts of the body to accomplish cell respiration. The respiratory system completes this important function of breathing throughout inspiration. In the breathing process inhaling oxygen is essential for cells to metabolize nutrients and carry out some other tasks, but it must occur simultaneously with exhaling when the carbon dioxide is excreted, this exchange of gases is the respiratory system's means of getting oxygen to the blood (McGowan, Jefferies & Turley, 2004).

a circulatory system which facilitates the exchange of materials for all but the simplest animals

I am going to show the similarities and differences of circulatory system of human and echinoderm. To begin with, I am going to write about the circulatory system of human. There are two types of circulation in circulatory system. First of all, pulmonary circulation is the part of the circulation, which carries oxygen depleted blood away from the heart, to lungs, and back to the heart. At first, in process of this circulation oxygen-depleted blood enters right atrium, and the blood pumped into the right ventricle. Then, the blood pumped to the pulmonary valve and goes into the pulmonary artery, and pulmonary artery separated into both right and left pulmonary arteries, which travel to each lung. At the lungs, the blood moves through capillary beds, which is the process that eliminating the carbon dioxide and adding oxygen to the blood. The oxygenated blood then leaves the lungs and goes back to the left atrium, and then blood flows to the left ventricle. From the left ventricle, the blood pumps to the aorta, which is delivering oxygenated blood to the whole body. Secondly, the systemic circulation is that carries oxygenated blood from the heart and to other parts of the body. First, in the process of systemic circulation, oxygenated blood from the lungs moves to left atrium, and then the blood pumps to the left ventricle. Then blood pumps to the aorta, and waste and carbon dioxide

Tim Taylor, 2012) has argued that cardiovascular system referred to as the circulatory system, is composed of blood within the blood vessels and heart. The function of the heart is pumping the blood through the blood vessels of the body.

The respiratory system and circulatory system are both critical to the life of a mammal. The respiratory and circulatory systems depend on each other greatly. An organism needs both systems to be functioning in order to sustain life. Oxygen needs to be exchanged throughout the body, and the respiratory system and circulatory system are the modes of transportation for the oxygen. The respiratory system establishes the breathing of an animal by the transfer of oxygen, which in return allows the circulatory system to work. According to Barilleaux (2014), the gap between respiratory tissues and aerobic tissues was bridged by the circulatory system.

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 blood that travels to the tissues and organs in the body have a high level of oxygen. Diffusion occurs between the capillaries and the body’s tissues and organs. Oxygen diffuses from the blood into the body’s cells and tissues, whereas carbon dioxide is diffused from the body’s tissues and organs into the blood where it then travels to the lungs. Here, it diffuses across the thin walls of the alveoli, where it is removed out of the body by exhalation.

Did you know the circulatory system comprises the heart, veins, capillaries and arteries? The system moves pure oxygenated blood in a continuous and controlled way from the lungs and heart so that blood can reaches every cell. Blood travels through a type of network of vessels that include capillaries that permeate every tissue of the body. Once it’s depleted of oxygen, the blood returns to the lungs and heart and the cycle continues.

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.

2. The exchanges of gas begins with the diffusion of oxygen down its gradient; oxygen present in the environment is greater compared to oxygen in tissues and vice versa for carbon dioxide. After the oxygen is inhaled, the oxygen binds to hemoglobin and then travels via the bloodstream into the alveolar capillaries in the lungs. The oxygen rich blood goes into the right side of the heart and the left side pumps it to the rest of the body while exhibiting a greater oxygen partial pressure at this point than the atmosphere. The exchanges of gases between the capillaries and the cells of the body occur by the diffusion of

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