Introduction:
Blood is a fluid connective tissue that circulates in the body to meet its nutritive and physiological needs. It comprises plasma and formed elements. Formed elements comprise various cellular and cellular fragments that are generated by the process of hematopoiesis, whereas the plasma mainly comprises water and plasma proteins.
Answer to Problem 1CYR
Correct answer:
The mast cell is not a formed element of the blood.
Explanation of Solution
Explanation for the correct answer:
Option (c) states that mast cell is not a formed element of the blood. A mast cell is a type of basophil (white blood cell) that differentiatesbetween tissues to perform its functions. Mast cells are the immune regulators of the body that secrete chemical substances to fight various infections and participate in allergic reactions. Hence, option (c) is correct.
Explanation for the incorrect answers:
Option (a) states that erythrocyte is not a formed element. Erythrocytes are suspended in the plasma of the blood. These are the red blood cells and area type of a formed element of the blood. So, it is an incorrect option.
Option (b) states that leukocyte is not a formed element. Leukocytes are white blood cells suspended in blood plasma and are a formed element of the blood. So, it is an incorrect option.
Option (d) states that platelet is not a formed element. Platelets are cell fragments found in blood and are a formed element of the blood. So, it is an incorrect option.
Hence, options (a), (b), and (d) are incorrect.
Therefore, it can be concluded that mast cells are not formed elements of the blood. They help in fighting against the infection.
