Circulatory System of Class 11
It is composed of following two elements:
Plasma : Alkaline (pH 7.35—7.45), viscous aqueous solution (viscosity is due to the presence of various proteins and other cellular materials) constitutes about 55% to total volume of blood, about 30-35% of total extracellular fluids (ECF).
Water about 90%.
Diffusible constituents include electrolytes, anabolic and catabolic substances formed during metabolism, hormones and vitamins.
Non-diffusible constituents include albumins, globulins, fibrinogen and various enzymes.
Proteins and other organic substances, protein about 7 % comprises of globulins, albumins, fibrogen & prothrombin.
Glucose about 1%.
Fats, endocrine secretion, enzymes about 2%.
Inorganic substances (chloride, bicarbonate, phosphate, calcium constitute about 1%).
Carries the digested food materials and endocrine secretions to different parts of body.
Maintains the actual continuity of flow.
