Question

What would happen if platelets were absent in the blood?
(a) The process of clotting will be affected.
(b) Kwashiorkor will be the result.
(c) RBC will be ruptured.
(d) The blood will become more liquid.

Answer 1

Hint:If there are no platelets in the blood, our skin would now no longer be capable of preventing the bleeding if we are wounded or cut.

Complete answer:To answer this question, at first, we have to know the importance of platelets of blood. Platelets are the colourless cell fragments present in the blood. They are related to clotting. In the absence of platelets, the method of clotting could be affected, If there could be any wound while platelets are absent, the animal will die with the aid of using shredding of all of the blood.

Now lets us find the solution from given options -
The blood platelets are required for the method of blood clotting. Whenever there is an injury, to save the loss of blood it is important to form a clot. The vitamin K, clotting factors, calcium ions and the platelets are important elements for the formation of a blood clot. If there are no platelets, there can be no clot formation. This may bring about haemorrhage wherein there is non-stop blood loss.

Kwashiorkor is an excessive form of malnutrition related to a deficiency in nutritional protein. The excessive loss of protein causes an osmotic imbalance in the gastro-intestinal machine inflicting swelling of the intestine identified as an edema or retention of water.
RBC will swell and go through hemolysis (burst) while located in a hypotonic solution. When located in a hypertonic solution, a red blood cell will lose water and go through crenation.
Platelets make up 1–2 percent of blood and help it to clot. Thin blood is referred to as thrombocytopenia and is caused through low numbers of platelets.

Thus, the right answer is ‘The process of clotting will be affected’.

Note:The impact of the platelet response is to prevent the bleeding and to form the site of the developing blood clot, or thrombus. If platelets are absent, this essential protection response cannot occur, and persistent bleeding from small wounds (extended bleeding time) results.
