Answer 2

The main components of the transport system in human beings are the heart, blood, and blood vessels.

♦  Heart pumps oxygenated blood throughout the body. It receives deoxygenated blood from the various body parts and sends this impure blood to the lungs for oxygenation.

♦ Blood transports nutrients, respiratory gases (CO2 and O2) waste products, harmones, water, inerganic ions and chemicals.

  Arteries carry blood from different organs of the body whereas veins collect the blood from different organs and bring it back to the heart.

♦ Blood-vessels (Arteries and Viens)

♦ Lymph - Lymph carries digested and absorbed fat from intestine and drains excess fluid from extra cellular space back into the blood.
