Answer 2

Human blood serves several important functions, but three of the main functions are:

1. Transportation of Oxygen and Nutrients: Blood carries oxygen from the lungs to all the cells in the body and delivers nutrients obtained from the digestive system to cells for energy and growth. This function is primarily carried out by red blood cells, which contain the protein hemoglobin that binds to oxygen.

2. Removal of Waste Products: Blood also plays a crucial role in removing waste products, such as carbon dioxide and metabolic byproducts, from cells and tissues. Carbon dioxide is transported from the cells to the lungs, where it is exhaled, while waste products are transported to the kidneys and liver for filtration and elimination.

3. Defense and Immunity: Blood contains white blood cells (leukocytes) and antibodies that help the body defend against infections, pathogens, and foreign invaders. White blood cells are a crucial component of the immune system and can identify and destroy harmful microorganisms and abnormal cells.

In addition to these three main functions, blood also helps regulate body temperature, maintain pH balance, and control bleeding through the clotting process. It plays a vital role in overall homeostasis and the proper functioning of the human body.
