GENERAL HISTOLOGY

Detailed explanation-1: -Blood is the chief transport system of the body. The primary function of blood is to deliver oxygen and nutrients and remove wastes from the body cells. The specific function of blood also includes defense, distribution of heat, and maintenance of homeostasis.

Detailed explanation-2: -The circulatory system delivers oxygen and nutrients to cells and takes away wastes. The heart pumps oxygenated and deoxygenated blood on different sides. The types of blood vessels include arteries, capillaries and veins.

Detailed explanation-3: -The respiratory system is involved in the transport of respiratory gases like oxygen and carbon dioxide in the blood. Hemoglobin and myoglobin are both essential oxygen-binding proteins. Hemoglobin transports oxygen in red blood cells (erythrocytes).

Detailed explanation-4: -Blood brings oxygen and nutrients to all the parts of the body so they can keep working. Blood carries carbon dioxide and other waste materials to the lungs, kidneys, and digestive system to be removed from the body.

Detailed explanation-5: -Final answer: The absorption of nutrients and exchange of respiratory gases between blood and tissues takes place in capillaries.
