Question

Name and explain the components of blood

Answer 1

Answer:

the components of blood are

1.plasma it is the colourless fluid part of blood.

2.RBC it is of biconcave shape which carries oxygen from lungs to tissues and vice versa

3. wBC these help in the development of immunity

4.platelets these help in the clotting contains protiens like albumin , globulin etc..

hope it helps ..

thank u

Answer 2

Blood, by definition, is a fluid that moves through the vessels of a circulatory system. In humans, it includes plasma (the liquid portion), blood cells (which come in both red and white varieties), and cell fragments called platelets.

Plasma is the main component of blood and consists mostly of water, with proteins, ions, nutrients, and wastes mixed in.

Red blood cells are responsible for carrying oxygen and carbon dioxide.

Platelets are responsible for blood clotting.

White blood cells are part of the immune system and function in immune response.

Cells and platelets make up about 454545\%%percent percent of human blood, while plasma makes up the other 555555\%%percent percent. The diagram below shows red blood cells, white blood cells of different types (large, purple cells), and platelets.

Plasma

Plasma, the liquid component of blood, can be isolated by spinning a tube of whole blood at high speeds in a centrifuge. The denser cells and platelets move to the bottom of the tube, forming red and white layers, while the plasma remains at the top, forming a yellow layer.

Red blood cells

Red blood cells, or erythrocytes, are specialized cells that circulate through the body and deliver oxygen to tissues. In humans, red blood cells are small and biconcave (thinnest in the center, just 777 - 888 μm in size), and do not contain mitochondria or a nucleus when mature.

Platelets and clotting

Platelets, also called thrombocytes, are cell fragments involved in blood clotting. They are produced when large cells called megakaryocytes break into pieces, each one making 200020002000 - 300030003000 platelets as it comes apart. Platelets are roughly disc-shaped and small, about 222 - 444 μm in diameter.

White blood cells

White blood cells, also called leukocytes, are much less common than red blood cells and make up less than 1\%1%1, percent of the cells in blood. Their role is also very different from that of red blood cells: they are primarily involved in immune responses, recognizing and neutralizing invaders such as bacteria and viruses.
