Substances; Biochemistry Lecturer; Akeel Abd Al-Ameer Biochemistry The aim of lecture ; is study of components of organism, especialy blood and cell. _To recognize at components of blood and the normal value of this components.
BLOOD Blood; Its’ red fluid have very complex composition service as transport medium in the body carrying oxygen , nutrition mineral ssage to the tissues COMPOSITION OF BLOOD; Its’ have two parts ; 1 -The suspended plasma fraction) 2 -cellular fraction; which have erythrocyte (red blood cells) and leukocyte white blood cells) And blood plates.
BLOOD Plasma have 92%water, solid dissolved such as protein albumin , globuline, fibrinogen and hemoglobin, lipids, carbohydrates , inorganic salt, hormones , vitamins. Blood serum; Its’ blood without fibrinogen freshly drawn blood soon formed aciot.
BLOOD GENERAL PROPERTIES OF BLOOD ; Oxygenated blood has characteristic bright Red colour, deoxygenated blood has dark red colour 2 - The specific gravity of blood =1. 054_1. 060 3 -p. Hof blood is (7. 35_7. 45). If the p. H fall than 7. 35 the condition called l Acidosis , if the p. H rise above 7. 45 , the condition called alkaloses, 4_The volume of blood (6_7) liter to adult. .

Coagulation and anti coagulation Blood clotting; Its' series of reaction occurred In which the solube plasma protein fibrinogen is converted into insolube fibrin , precipitation in the form of long threds that Cling together resemble aspongy mass.
MECHANISM OF CLOTTING Prothrombine +_thromboplastine___Ca++____ thrombin s the base metal in clotting which do on transformation. __________ fibrin thrombin fibrinogen Ca++ is very necessary for clotting the blood. the coagulation of freshly Drawn blood samples may be prevented by adding substances that remove calcium. There are two types of anticoagulants ; 1_natural 2_industerial _
