A blood cell that is bi-concave in shape and contains hemoglobin is called a(n):
A
erythrocyte
B
leukocyte
C
plasma
D
thrombocyte
Explanation: 

Detailed explanation-1: -Erythrocytes are biconcave enucleate red blood cells responsible for transport of O2/CO2 between the body’s tissues and lungs; their oxygen-carrying capacity is due to their high hemoglobin content.

Detailed explanation-2: -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-3: -Also called RBC and red blood cell.

Detailed explanation-4: -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.
