MICROANATOMY

Detailed explanation-1: -Red blood cells are responsible for transporting oxygen from your lungs to your body’s tissues. Your tissues produce energy with the oxygen and release a waste, identified as carbon dioxide. Your red blood cells take the carbon dioxide waste to your lungs for you to exhale.

Detailed explanation-2: -Hemoglobin (Hb) constitutes a vital link between ambient O2 availability and aerobic metabolism by transporting oxygen (O2) from the respiratory surfaces of the lungs or gills to the O2-consuming tissues.

Detailed explanation-3: -Haemoglobin is a protein and the respiratory pigment found in red blood cells. The main function of haemoglobin is to carry oxygen throughout our body. It also transports some amount of carbon dioxide from different parts of the body to the lungs.

Detailed explanation-4: -Oxygenated blood returns to the heart and is distributed throughout the body by way of the systemic vasculature. Oxygen is carried in the blood in two forms. The vast majority of oxygen in the blood is bound to hemoglobin within red blood cells, while a small amount of oxygen is physically dissolved in the plasma.
