Physiology of circulatory system. The circulatory system is the continuous system of tubes through which the blood is pumped around the body. It supplies the tissues with their nutritional requirements and removes waste products. The pulmonary circulatory system circulates deoxygenated blood from the heart to the lungs via the pulmonary artery and returns it to the heart via the pulmonary vein.

Physiology of Circulation Roles of Capillaries In addition to forming the connection between the arteries and veins capillaries have a vital role in the exchange of gases nutrients and metabolic waste products between the blood and the tissue cells. The human circulatory system consists of two blood circuits. The systemic circuit and the pulmonary circuit.

This is why the human circulatory system is described as a double circulatory system. The systemic circuit carries blood to all the major organs of the body except the lungs. The lungs have their own blood circuit called the pulmonary circuit.

Excess tissue fluid is returned to the venous system by lymphatic vessels. Edema occurs when excess tissue fluid accumulates. Venules continue from capillaries and merge to from veins.

The human body contains around 5 liters of blood. Blood is a viscous fluid which flows inside the vessels of the circulatory system. It consists of different kinds of blood cells suspended in a liquid called plasma.

Plasma makes up about 55 of our blood volume. It is a yellow liquid part of the blood in which red and white blood cells as well as platelets are suspended. 95 of it consists of water with many substances.

Pulmonary circulation includes a vast network of arteries veins and lymphatics that function to exchange blood and other tissue fluids between the heart the lungs and back. They are designed to perform certain specific functions that are unique to the pulmonary circulation such as ventilation and gas exchange. A main function of the circulatory system is to move blood from one part of the heart to the lungs where oxygen is picked up and carbon dioxide is dropped off see respiratory system.

This blood is then moved from the lungs to a different part of the heart and from there it is moved around the body. As the blood moves around the. Physiology Of Circulation.

The human circulatory system circulates blood through two loops double circulation One for oxygenated blood another for deoxygenated blood. The human heart consists of four chambers two ventricles and two auricles.

The human circulatory system possesses a body-wide network of blood vessels. These comprise arteries veins and capillaries. The respiratory system controls gas exchange to supply the body with oxygen as it removes carbon dioxide in the lungs after passage through the nasal cavity pharynx larynx trachea and bronchus.

The circulatory system consists of the heart blood vessels and blood and delivers oxygen and nutrients to the tissues while removing carbon. The circulatory system also called cardiovascular system is a vital organ system that delivers essential substances to all cells for basic functions to occur. Also commonly known as the cardiovascular system is a network composed of the heart as a centralised pump bloods vessels that distribute blood throughout the body and the blood itself for transportation of different substances.

A The circulatory system consists of a series of vessels that transport blood to and from the heart the. B The circulatory system has two major circuits. The pulmonary circuit which transports blood to and from the lungs and the systemic circuit which transports blood to and from the body excluding the lungs.

The circulatory system functions to deliver oxygen and nutrients to tissues for growth and metabolism and to remove wastes. The heart pumps blood through a circuit that includes arteries arterioles capillaries venules and veins. The circulatory system is a network of vesselsthe arteries veins and capillariesand a pump the heart.

In all vertebrate organisms this is a closed-loop system in which the blood is largely separated from the bodys other extracellular fluid compartment the interstitial fluid which is the fluid bathing the cells. The superficial system drains into the hemiazygos and azygos veins which ultimately drain into the right heart with the systemic venous return. However the deep circulation drains into the pulmonary vein and thus left ventricle.

As a result the deep bronchial system effectively functions as an arteriovenous shunt. Physiology of the Blood Vessels. The circulatory system is the continual system of tubes through which the blood is pumped around the body.

It supplies the tissues with their nutritional needs and gets rids of toxins. Resistance pressure and force are the three main components that influence the blood circulation. The Circulatory System Cardiovascular System major connection between external and internal environment.

Everything going in or out of body must go through the circulatory system to get to where its going more than 60000 miles of blood vessels with a pump that beats 100000 times each day General Functions of Circulatory System. The circulatory system provides bones the nutrients and oxygen they need to grow and repair. Bone marrow produces blood cells in a process called hematopoiesis.

The integumentary system and circulatory system work closely together to accomplish several functions. Capillaries in the skin can dilate to release heat and cool the body down.
