What does blood consists of?-Blood consists of… Red blood cell Plasma White blood cell Platelets
What are the functions of Blood?-Transport oxygen away from the lungs and around the body-Transport nutrients such as glucose fromthe digestive system into the cells in ourBodies.
Red blood cellWhat are the functions of the red blood cell?-The primary function of red blood cells is to carry oxygenfrom the lungs to the tissues around your body. They are alsoimportant in getting waste carbon dioxide from your tissuesto your lungs, where it can be released.
White blood cellWhat are the functions of the white blood cell?-The white blood cell are part of the immune system. The bodyuses white blood cells to fight infection and foreign objects inthe body .Several types of white blood cells used to fightdifferent infections.
Plasma What are the functions of the plasma?-Plasma is the liquid part of blood and carries dissolved substances such as glucoseand other products of digestion, hormones, vitamins, urea and carbon dioxide andtransports them to all parts of body .The plasma makes the blood liquid, the cells inthe blood are suspended in the plasma. Thus ,when you cut yourself ,the bloodcomes out as a liquid.
Platelets What are the functions of platelets?-Platelets are certain types of cell present uniformly in the bloodstream.Platelets are responsible for the healing of injuries and the provision of fibrin(wideelastic protein formed from fibrinogen when blood clots)threads to seal the wounds.Platelets are red in colour and oval in shape.
What are the blood vessels and their uses?-Blood vessels are part of the circulatory system that transportblood throughout the body.There are 3 major types of blood vessels: Arteries, veins andlastly the capillaries.
ARTERIES What are the functions of arteries?-The arteries carry blood away from the heart. This blood isoxygenated, exceptions made for the pulmonary andumbilical(supply deoxygenated blood from the fetus) arteries.The circulatory system is important for the delivery of oxygenand nutrients to all cells and the removal of carbon dioxide andwaste products, maintenance of optimum pH and the mobility ofthe elements.
CAPILLARIESWhat are the functions of capillaries?-Capillaries are the smallest of a bodys blood vessels. Their endothelial linings areonly one cell thick. They enable the exchange of water , oxygen ,carbon dioxideand many other nutrients and waste chemical substances between blood andsurrounding tissues .New capillaries are formed by the process of blood vesselsformation occurring by a production of endothelial(thin layer of cells that lines theinterior surface of blood vessels)cells forming into vascular tubes.
VEINSWhat are the functions of the veins?-In the circulatory system, veins are blood vessels that carryblood back towards the heart. Veins are often closer to the skin andcontain valves(a device to control the flow of liquid) to help keepblood flowing toward the heart.
