  1. Plasma is the main component of blood and consists mostly of water, with proteins, ions, nutrients, and wastes mixed in. Red blood cells are responsible for carrying oxygen and carbon dioxide. Platelets are responsible for blood clotting. White blood cells are part of the immune system and function in immune response
  2. Layers of Blood Vessels. Both arteries and veins consist of three layers. Tunica Intima: It is the innermost and thinnest layer of arteries and veins, which have a direct contact with the blood flow.; Tunica Media: It is the middle layer of an artery or vein, which is made up of smooth-muscle cells.; Tunica Externa: It is present adjacent to the tunica media and is composed of collagen and.

Class 10 science E.M. Topic= Blood, classification of Blood, Functions of R.B.C, W.B.C. and Platele Ans: Blood is made up of two main components - Plasma and Blood cells. Plasma is a straw-coloured viscous fluid which is 90% water and has many proteins in it. It also has mineral ions, glucose, hormones, carbon dioxide. It makes up for 55 % of the blood. The other 55% of it is made up blood cells The function of platelets is to repair small blood vessels and prevent dangerous amounts of blood from leaking out. When a person is cut, platelets rush to the area and cling to the blood vessels that have been damaged, sealing them. Platelets were once called thrombocytes. Platelets are tiny cell fragments that are found within our blood Solution: When blood vessels are cut or damaged, the loss of blood from the system must be stopped before shock and possible death occur. This is accomplished by solidification of the blood, called as coagulation or clotting. The smallest cells in the blood are platelets which are designed for this particular purpose

Blood cells and its types with function

High Platelet Count. Platelets, also known as thrombocytes, are blood cells responsible for blood clotting. If a blood vessel wall becomes damaged, platelets will rush to the site of injury and form a plug or clot to stop the bleeding. If platelet count is low (a condition called thrombocytopenia), the risk of uncontrolled or prolonged bleeding. It consists of: (a) plasma, (b) RBC, (c) WBC, and (d) blood platelets. Plasma transports food, CO 2 and nitrogenous wastes in dissolved form. RBC transports respiratory gases and hormones. WBC protects the body from infections and platelets prevent the loss of blood at the time of injury by forming blood clots Lymph acts as a middle man which transports oxygen, food materials, hormones, etc., to the body cells and brings carbon dioxide and other metabolic wastes, from the body cells to blood and then finally pours the same into the venous system. 2.
