What is the role of blood in the human body?
as blood in the human body circulates, oxygen and nutrients are supplied to cells, while the waste products are simultaneously collected and transported to organs that get rid of them. In addition, blood has special cells that protect the body against diseased grocery bacteria, thus acting as armor against infection. One component of blood seals damaged blood vessels to prevent blood leakage. Blood also plays a role in heat distribution. With these functions, blood acts as a transport mechanism, waste removal, defense, repair and maintaining the heat of the human body.
veins, arteries and capillaries are part of a network of moving oxygen and nutrients through the body and remove waste products. From the heart is the first blood vessel that the blood passes through the artery called aorta. Blood in the human body then passes through the capillaries and then lives and back into the heart. The heart, blood vessels and blood cooperate on creating a circulatory system that provides all the needs of body cells.
Blood in the human body contains red and white blood cells, platelets and plasma. When blood passes through the lungs, oxygen is picked up by a substance called hemoglobin in red blood cells. Transmission of nutrients and waste products, as well as maintaining body temperature, is a role played by plasma, a liquid that consists of water and other substances such as cholesterol. Plasma also serves as a medium to transport other blood components to perform their functions.
white blood cells, especially lymphocytes and phagocytes, destroy bacteria causing diseases that seek to cause infection in the body. Chemical compounds called antibodies are released by lymphocytes to weaken bacteria that will be absorbed by phagocytes. Lymphocytes also have the ability to recognize that that has already caused infection, which forces them to react faster if the same bacteria try to re -cause infection. Neutrophils, Eosinophils, Basophils and Monocytes are all types BBreast blood cells that have specific roles in the fight against infections.
Plates are part of the blood in the human body that are much smaller than red and white blood cells. When clotting blood is a essential substance that the plates release in the break -up, called thrombokinase or thromboplastin. Another important role of plates is the connection of capillary leaks, which can otherwise become an entrance point for germs. This can also prevent blood loss.
