IMPORTANT POINTS
♦ The cells of every animals need O2 and nutrients for performing different metabolic activities, and same way end of this process CO2 and wastes are removed. Hence body fluid is flow throughout the body by blood and lymph.
Blood as a fluid connective tissue made of body corpuscles.
♦ In the composition of blood plasma, water, salts and proteins are included. It covers 55 % of blood. RBC, WBC and platelets are included in blood corpuscles. It covers 45 % of blood.
♦ In human ABO and Rh blood groups are found. In which A, B, AB and O blood groups are included in ABO, while Rh+ve and Rh–ve included in Rh group.
♦ The major chemical defense against blood loss is the formation of blood clot. In it 13 factors are included. This process involves three phases
(i) Formation of thromboplastin
(ii) Formation of thrombin
(iii) Formation of fibrin
The composition of lymph is similar to blood plasma. It flows in body through lymphatic vessels.
♦ Human having close circulation. In it blood vessels (artery, vein and capillaries) and heart are included.
