MICROANATOMY

Detailed explanation-1: -The blood transports oxygen from the lungs to the cells of the body, where it is needed for metabolism. The carbon dioxide produced during metabolism is carried back to the lungs by the blood, where it is then exhaled (breathed out).

Detailed explanation-2: -Oxygen, nutrients and hormones are delivered around the body in the blood and carbon dioxide and other waste products are removed. The heart is constantly pumping blood so it is always moving around the body.

Detailed explanation-3: -Summary. 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-4: -Blood Transports Nutrients and Hormones These nutrients include glucose, amino acids, vitamins, minerals, and fatty acids. Blood also transports some hormones secreted by endocrine system glands to target organs and tissues.

Detailed explanation-5: -Oxygen enters the body through the nose and mouth and passes through the lungs into the bloodstream. Once in the bloodstream, oxygen helps replace cells that wear out, provides energy for our bodies, supports the way our immune system functions and more.
