It plays an, important role in the transport of oxygen, nutrients, excretory substances, etc., Blood, Separation of the components of blood, Observation of components of blood, , Take a little blood in a test tube. Add some chemicals which prevent clotting like EDTA, and shake the test, tube well. Keep the test tube at rest for a while and observe. The components of the blood can be seen, separated as plasma (55%) and blood cells (45%)., , Observation: The components of blood can be seen., Components of blood:, , Plasma - 55% Blood cells-45%, A+ BLOG-www.apluseducare.blogspot.com 9072708051, , Page 1

A+ BIOLOGY-IX, Anticoagulants that prevent clotting of blood, , Anticoagulants are substances that delay clotting of blood. They are administered under the guidance of, specialised doctors. There are many anticoagulants and of various types also., EDTA (Ethylene Diamine Tetra Acetic acid), , It is a chemical substance that prevents coagulation., , By adding EDTA we can separate the blood cells from its fluid part, Components of blood, , The blood consists of 55% liquid plasma and 45% blood cells., Blood cells, , Red blood cells (RBC-Erythrocyte), , White blood cells (WBC-Leucocyte), , Platelets, Plasma, , Major components of plasma, , Water, proteins, fat, sugar, minerals, urea, uric acid, hormones, Factors absorbed through plasma, , The simpler molecules formed as a result of digestion, namely glucose, amino acids, fatty acids, glycerol etc., reach cells through the plasma., Proteins in plasma and their functions,  Albumin - Regulates blood pressure,  Globulin – Helps in defense,  Fibrinogen - Plays a major role in the coagulation of blood., Name the other factors in Plasma (1% - 2%):,  Fat • Sugar • Salts • Urea • Uric acid • Hormones., Prepared by:, , Riyas, HST NS, PPMHSS Kottukkara, Kondotty-Malappuram, 9747944422, , More Resources, Visit https://apluseducare.blogspot.com/, , A+ BLOG-www.apluseducare.blogspot.com 9072708051, , Page 2
