Correct answer: D. Placenta
- A. Ovary
- B. Uterus
- C. Pituitary gland
- D. Placenta
Explanation
A chorionic gonadotropin hormone (CG or hCG) is primarily secreted by the placenta during pregnancy. hCG plays a crucial role in maintaining the corpus luteum (a structure that forms after ovulation) during the early stages of pregnancy, which in turn helps support the production of progesterone to sustain the pregnancy until the placenta can take over this function later on.

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
