What are the six functions of blood?

Answer 1

The functions of the blood are:

1. to transport oxygen away from the lungs and around the body; and CO2 from the body cells to the lungs.
2. to transport nutrients such as glucose and amino acids from the digestive system to the cells in our bodies.
3. to take waste products such as lactic acid away from the muscles when it's produced by anaerobic respiration; and urea from the liver to the kidneys and bladder.
4. By maintaining a good circulation, the bloodflow keeps your core body temperature at a steady 37oC.
5. White blood cells help kill pathogens and microbes that stray into the body.
6. Substances like platelets and fibrin in the blood help to clot wounds.

Answer 2

1) blood carries oxygen from your lungs to all your body cells. Carbon dioxide diffuses from your body cells into your blood. Your blood carries carbon dioxide to your lungs to be exhaled.

2) Blood carries waste products from your cells to your kidneys to be removed

3) Blood transports nutrients and other substances to your body cells.

4) Cells and molecules in blood fight infections and help heal wounds.

Answer 3

1. To transport oxygen and nutrients from the lungs and intestines respectively to all cells in your body.
2. To fight pathogens and kill bacteria and other microbes.
3. Messenger functions (E.g. Transportation of hormones)
4. To help heal and clot wounds.

Answer 5

Blood transports nutrients and wastes to and from the body cells. It provides a mode of transport for hormones. It moves immune cells throughout the body so they can be ready to act. It acts to maintain body temperature.

Answer 6

1. Transportation of oxygen, nutrients, hormones, and waste products throughout the body.
2. Regulation of body temperature, pH balance, and fluid balance.
3. Protection against infection through the immune response and blood clotting.
4. Maintenance of homeostasis by balancing electrolytes and maintaining blood pressure.
5. Delivery of antibodies and white blood cells to fight infections.
6. Clot formation to prevent excessive bleeding when blood vessels are damaged.
