NEET PG DENTAL EXAM

Detailed explanation-1: -The shape of the human red blood cell (RBC) is known to be a biconcave disc. The experiments in this paper identify some of the underlying determinates. RBC ghosts were made such that they were spheres in hypo-osmotic solutions and biconcave discs in iso-osmotic solutions.

Detailed explanation-2: -Red blood cells are microscopic and have the shape of a flat disk or doughnut, which is round with an indentation in the center, but it isn’t hollow. Red blood cells don’t have a nucleus like white blood cells, allowing them to change shape and move throughout your body easier.

Detailed explanation-3: -The mature human red blood cell is small and devoid of the nucleus. The shape of RBC can be described as biconcave disc. It is the biconcave disc shape that helps in increasing its surface area. It is flexible and assumes a bell shape as it passes through extremely small blood vessels.

Detailed explanation-4: -The larger surface area of RBCs provides more exchange of oxygen and carbon dioxide. Due to such a shape, RBC can swell easily and squeeze easily through small capillaries without any rupture or damage. Hence, the advantage of RBCs being biconcave is that it increases the surface area.
