PATHOLOGY

Detailed explanation-1: -One of the key functions of blood is transport. Blood vessels are like networks of roads where deliveries and waste removal take place. Oxygen, nutrients and hormones are delivered around the body in the blood and carbon dioxide and other waste products are removed.

Detailed explanation-2: -These include oxygen, carbon dioxide, nutrients (such as glucose and amino acids), hormones and waste chemicals such as urea. These substances are transported in a medium called blood through the body through tubes called blood vessels. The blood is forced around these vessels by a pump-the heart.

Detailed explanation-3: -As the heart beats, it pumps blood through a system of blood vessels, called the circulatory system. The vessels are elastic tubes that carry blood to every part of the body.

Detailed explanation-4: -transporting oxygen and nutrients to the lungs and tissues. forming blood clots to prevent excess blood loss. carrying cells and antibodies that fight infection. bringing waste products to the kidneys and liver, which filter and clean the blood. regulating body temperature.
