List four functions of blood.

Ans : Functions of Blood :

 

1.

Transports:

Dissolved gases (e.g. oxygen, carbon dioxide);

Waste products of metabolism (e.g. water, urea);

Hormones;

Enzymes;

Nutrients (such as glucose, amino acids, micro-nutrients (vitamins & minerals), fatty acids, glycerol);

Plasma proteins (associated with defence, such as blood-clotting and anti-bodies);

Blood cells (incl. white blood cells 'leucocytes ', and red blood cells 'erythrocytes ').

2.

Maintains Body Temperature

3.

Controls pH

The pH of blood must remain in the range 6.8 to 7.4, otherwise it begins to damage cells.

4.

Removes toxins from the body

The kidneys filter all of the blood in the body (approx. 8 pints), 36 times every 24 hours. Toxins removed from the blood by the kidneys leave the body in the urine.
(Toxins also leave the body in the form of sweat.)

5.

Regulation of Body Fluid Electrolytes

Excess salt is removed from the body in urine, which may contain around 10g salt per day
(such as in the cases of people on western diets containing more salt than the body requires).

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.

functions of blood are:

  • Transports oxygen and nutrients to the cells of the body.
  • Carries waste away from the cells
  • Helps in maintaining the body temperature.
  • Hormones are distributed to the different parts of the body via blood, etc.

Four functions of blood are - 

1) It transports oxygen, digested food,hormones,etc to all parts of our body.

2) The white blood cells present in the blood helps o fight diseases.

3) The red blood cells increases the heamoglobin level in our body.

4) Plasma present in the blood contains salt and hormones necessary for our body.

Hope this helps you..!!!

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 transport nutrients and other substances to your body cells.

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