Objectives of this lecture: list and describe the components of blood, describe the roles of blood components, explain the formation of blood components, explain the control of red blood formation, explain the process of haemostasis. Plasma (c. f serum: water, electrolytes, nutrients, wastes, hormones, plasma proteins, albumins, help with the osmolality of the fluid- keep the water where it is supposed to be. If there is a rise or fall of plasma proteins- affects the water balance: globulins ( , , , antibodies, fibrinogen, key factor in blood clotting process. Red blood cells (erythrocytes: biconcave disk, no nucleus (except avian, mammalian cells lose its nucleus, haemoglobin: transport, has a number of roles- carrying different substances, oxygen, carbon dioxide, h, no. Important for regulating vasoconstriction or dilation of arterioles: carbonic anhydrase: co. Getting rid of carbon dioxide from the body: buffering, buffer changes in ph.
