Match the following.

$\begin{array}{cc}ColumnI& ColumnII\\ \text{(i). hCG}& \text{a. Stimulates duct development in breasts.}\\ \text{(ii). hCS}& \text{b. Relaxes the pelvic ligaments and widens the cervix.}\\ \text{(iii). Relaxin}& \text{c. Continued production of progesterone by the luteal cells.}\\ \text{(iv). Estrogen}& \text{d. Increases the amount of glucose in the mother’s blood.}\end{array}$

• A. i)➡ d ,ii)➡ c, iii)➡ a, iv) ➡ b

Answer 1

The correct option is B

i)➡ c, ii)➡ d, iii)➡ b, iv) ➡ a

The human chorionic gonadotropic hormone (hCG) produced by the placenta preserves the corpus luteum which in turn produces progesterone. Progesterone increases the vasculature of the uterine lining to provide blood supply for the developing embryo. Human chorionic somatomammotropin (hCS) decreases glucose uptake by the mother’s cells, increasing the mother’s blood glucose level, thereby increasing the amount that reaches the growing foetus. Relaxin is secreted by the placenta. Its main function is to soften and relax the pelvic ligaments and soften and widen the cervix. During pregnancy, estrogen stimulates extensive duct development in the mammary glands of the breasts.
