| Blood is one of the essential body fluids that the human body conducts its significant functions needed in maintaining life within the body. It constitutes about 7-8 percent of an individual’s body weight, and it flows through arteries, veins, and capillaries providing oxygen, nutrients to the cells while collecting waste products such as carbon dioxide. The four components that form blood are red cells, white cells, platelets, and plasma. About 45% of all the volume of blood is constituted by erythrocytes or red blood cells, which contain hemoglobin-protein that captures oxygen from the lungs and transports it to tissues throughout the body. These carry carbon dioxide back into tissues to the lungs to be exhaled out. Scientifically, white blood cells are leukocytes, a part of the human immunity system. White blood cells fight infections and invading agents that try to enter the body. Among its varieties are neutrophils, lymphocytes, monocytes, eosinophils, and basophils, with each variety being given a particular duty in immune defense. Actually, thrombocytes are known as platelets, while they are really small pieces of cells that represent a very crucial role for blood clotting. With the immediate clumping of these platelets at the site once the vessel is injured, a plug develops through the release of chemicals that facilitate clotting and prevent easy bleeding. Plasma is liquid and makes up approximately 55 percent of the total volume of blood. This refers to that fluid thin and straw-colored liquid that, essentially, is water with dissolved proteins, electrolytes, hormones, and other waste products dissolved in it. Plasma serves as the transport medium of nutrients, hormones, and waste products distributed throughout the body. Through basic functions of blood, it has to maintain homeostasis by regulating the heat, pH, and volume of fluids. It also serves as a medium for transporting hormones and facilitating their responses within the immune system. |
