GENERAL HISTOLOGY

Detailed explanation-1: -In humans, as in all mammals, the mature RBC lacks a nucleus. This allows the cell more room to store hemoglobin, the oxygen-binding protein, enabling the RBC to transport more oxygen. RBCs are also biconcave in shape; this shape increases their surface area for the diffusion of oxygen across their surfaces.

Detailed explanation-2: -Red blood cells contain hemoglobin and are covered with a membrane composed of proteins and lipids. Hemoglobin-an iron-rich protein that gives blood its red color-enables red blood cells to transport oxygen and carbon dioxide. Red blood cells do not have nuclei, allowing for more room for hemoglobin.

Detailed explanation-3: -A type of blood cell that is made in the bone marrow and found in the blood. Red blood cells contain a protein called hemoglobin, which carries oxygen from the lungs to all parts of the body.

Detailed explanation-4: -Answer and Explanation: The erythrocytes are the blood cells that contain hemoglobin. The erythrocytes are also known as red blood cells (RBCs) and are the most highly adapted cells in the body.
