Answer:
radius of human red blood cell; 3.7 × 10–6m
Answer:
True
Explanation:
Red Blood Cells or Erythrocytes (Erythro = Red, Cyte = Cell) carry oxygen to all the major parts of the body, it is these that give the blood it’s red colour although the actual colour varies depending on the level of Oxygen in the blood - veins, carrying deoxygenated blood back to the heart, carry darker red blood cells as they have no oxygen. Arteries do the opposite, carrying Oxygenated blood away from the heart to the vital organs, this blood is a bright red as it has the Oxygen. The only exception to this is the Pulmonary System where the process is reversed as the Pulmonary Artery transports Oxygenated Blood from the Lungs back to the heart, the Pulmonary vein carries deoxygenated blood to the lungs where it receives oxygen. This is a basic overview and there are fuller answers elsewhere so sorry if it’s not what you wanted.
In general, the diameter of human red blood is lie between 6.2–8.2 µm and the thickness at the thickest point is lying between 2–2.5 µm and the minimum thickness is 0.8–1 µm, which is at the centre.
Hence, the given statement for radius of human blood cell is true.
