A. Blood vessels, xylem and red blood cells
B. Plasma, red blood cells, white blood cells and platelets
C. Red blood cells, white blood cells and blood platelets
D. Plasma, sap, red blood cells and white blood cells

Answer 1

Hint: The blood is a very important fluid of the body and it is considered as connective tissue. The blood involved in the transportation of gases, nutrients, and other important nutrients throughout the body.

Complete Answer:
- Blood is a connective tissue and is made up of plasma, red blood cells, white blood cells, and platelets. The plasma is a yellowish liquid component that holds the blood cell.
- In the liquid part of the blood carries the protein all over the blood. It covers about 55% of the body total blood. The red blood cells are important for the exchange of carbon dioxide and oxygen throughout the body; it is made up of bone marrow of the bones. The white blood cells involved in the immune response of the body.
- Whenever there are any antigens in the body, the white blood cells get activated and produce the defense mechanism. The platelets are small blood cells that are involved in the blood clotting process to stop the bleeding whenever we get any cut in our body.
- If any of our blood vessels get damaged, it sends a signal to the platelets, then the platelets form a clot to repair the damage and this complete process of spreading throughout the surface of the damaged vessels is termed as adhesion.
- When the platelets reach the injured sites, they release a sticky tentacle that helps them to get adhere together and release chemical signals to attract more platelets and the addition of more platelets pile up to form clot is considered as the aggregation process.

Thus, the correct option is ‘B’. Plasma, red blood cells, white blood cells and platelets.

Note: The platelets are made of bone marrow in association with the white blood cells and another name of platelets is thrombocytes. After the platelets circulate inside our bloodstream they stay for 8-10 days.
