Which of the following carries oxygen to various parts of human body?
Red blood cells
Red blood cells (erythrocytes) carry oxygen throughout the body. They contain haemoglobin, an iron-containing protein that binds oxygen in the lungs (where partial pressure is high) and releases it to tissues (where partial pressure is low).
White blood cells are immune cells; plasma is mostly a transport medium for nutrients, hormones and wastes (only a tiny fraction of oxygen dissolves in it); nerves transmit electrical signals, not gases.
