ANATOMY

Detailed explanation-1: -Oxygen, nutrients and hormones are delivered around the body in the blood and carbon dioxide and other waste products are removed.

Detailed explanation-2: -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-3: -The heart, blood and blood vessels work together to service the cells of the body. Using the network of arteries, veins and capillaries, blood carries carbon dioxide to the lungs (for exhalation) and picks up oxygen. From the small intestine, the blood gathers food nutrients and delivers them to every cell.

Detailed explanation-4: -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: -All red blood cells contain a red pigment known as hemoglobin. Oxygen binds to hemoglobin, and is transported around the body in that way. In tiny blood vessels in the lung, the red blood cells pick up oxygen from inhaled (breathed in) air and carry it through the bloodstream to all parts of the body.
