(a) Erythrocytes and leucocytes (function)
(b) Artery and vein (direction of blood flow)
(c) Artery and vein (type of blood primarily flowing through)
(d) Tricuspid and bicuspid valves (location).
(a)
Erythrocytes | Leukocytes |
a) Erythrocytes transport oxygen to various parts of the body. | b) Leukocyte engulf particle like solid substances like bacteria by phagocytosis. |
b) It contains haemoglobin which readily combine with oxygen. | b) It contains antibodies which fights with the antigens. |
(b)
Artery | Vein |
In arteries, blood travels from heart to other organs in the body. | In veins , blood is carried from other organs to the heart. |
(c)
Artery | Vein |
In arteries , oxygenated blood flows from heart to other parts of body. | In veins , de oxygenated blood flows to the heart from other organs. |
(d)
Tricuspid valve | Bicuspid valve |
Tricuspid valve is present at the aperture between right auricle and right ventricle. | Bicuspid valve is present at the aperture between left auricle and left ventricle. |
