Question

explain the structure and function of human blood​

Answer 1

Explanation:

Blood supports growth by distributing nutrients and hormones, and by removing waste. Red blood cells contain hemoglobin, which binds oxygen. These cells deliver oxygen to the cells and remove carbon dioxide. Blood plays a protective role by transporting clotting factors and platelets to prevent blood loss after injury.

Answer 2

Structure-

A) TRANSPORT FUNCTION-

1) GASES- oxygen via blood from lungs to cell and CO2 from tissues to lungs.

2) NUTRIENTS- nutrients like glucose, amino acids, fatty acids transported to each cell.

3) ENZYMES OF HORMONES- blood transport enzymes and hormones from the site of their action.

B) PROTECTION- Antibodies are produced in the blood and they protect the body from microbes and harmful particles.

C) maintaining the balance of minerals like sodium and potassium in the body.

Functions of blood cells-

1) RBCs- with haemoglobin it carries out transport of respiratory gases.

2) WBCs- produce antibodies and gives immunity to body.
