Question

Fill up the blanks with appropriate cells and secretions of Areolar tissue:

(i)____ are secretory cells that release Heparin.
(ii)_____ is an anticoagulant, histamine a vasodilator that lowers blood pressure and serotonin a vasoconstrictor that increases BP.
(iii)____ are immune cells that are phagocytic that is they digest invading pathogens or general tissue waste.
(iv)____ produce white and yellow fibers which, are present in high quantity in areolar tissue.

• A. (i)-Mast cells, (ii)-Heparin, (iii)- Macrophages, (iv)- Fibroblasts.
• B. (i)-Heparin, (ii)-Macrophages, (iii)-Fibroblasts, (iv)- Mast cells.
• C. (i)-Macrophages, (ii)-Fibroblasts, (iii)-Mast cells, (iv)-Heparin.
• D. (i)-Fibroblasts, (ii)-Heparin, (iii)-Mast cells, (iv)-Macrophages.

Answer 1

The correct option is A

(i)-Mast cells, (ii)-Heparin, (iii)- Macrophages, (iv)- Fibroblasts.

Mast cells are secretory cells of areolar that secrete Heparin an anticoagulant, Histamine a vasodilator that lowers BP and Serotonin, a vasoconstrictor that increases blood pressure. Macrophages are immune cells that are phagocytic, that is, they digest invading pathogens or general tissue waste. Fibroblasts produce white and yellow fibers, which are present in high quantities in areolar tissue.
