The components of blood in man are?

The correct answer is: red blood cells, white blood cells, plasma and platelets. Blood is a complex fluid that is made up of different components, each with a specific function.

- Red blood cells (also called erythrocytes) are responsible for carrying oxygen from the lungs to the rest of the body. They have a biconcave shape that allows them to carry more oxygen and are flexible so they can move through the smallest blood vessels.

- White blood cells (also called leukocytes) are part of the body's immune system and help fight infections. There are different types of white blood cells, each with a specific function, such as identifying and destroying harmful bacteria and viruses.

- Plasma is the yellowish fluid part of blood that makes up about 55% of total blood volume. It contains water, proteins, hormones, and waste products. Plasma also helps to transport nutrients, hormones, and waste products throughout the body.

- Platelets (also called thrombocytes) are small, disc-shaped cells that play a crucial role in the formation of blood clots. When there is an injury or wound, platelets clump together to form a clot and stop bleeding.

So, red blood cells, white blood cells, plasma and platelets.
