Answer 2

Answer:

(a )Fertilization of an egg by a sperm normally occurs in the fallopian tubes. The fertilized egg then moves to the uterus, where it implants to the uterine lining.

(b)The ovaries have two main reproductive functions in the body. They produce oocytes (eggs) for fertilisation and they produce the reproductive hormones, oestrogen and progesterone.

(c) When the egg is not fertilized, it is shredded off from the body and menstrual cycle takes place. Ovary releases one egg every month. At the same time, the uterus also prepares itself to receive a fertilized egg. The endometrium lining becomes thick and spongy for carrying embryo.

(d)The body uses several routes to eliminate toxicants or their metabolites . The main routes of excretion are via urine, feces, and exhaled air. Thus, the primary organ systems involved in excretion are the: Urinary system.
