MEDICAL PHYSIOLOGY

Detailed explanation-1: -The primary reproductive organs, or gonads, consist of the ovaries and testes. These organs are responsible for producing the egg and sperm cells gametes), and hormones.

Detailed explanation-2: -The primary reproductive organs are the gonads, which produce the gametes and hormones. The secondary, or accessory, structures transport and sustain the gametes and nurture the developing offspring.

Detailed explanation-3: -Male gametes (spermatozoa) are produced by cells (spermatogonia) in the seminiferous tubules of the testes during spermatogenesis (Fig. 4.2). Spermatogonia undergo mitotic divisions to produce additional spermatogonia, which differentiate into primary spermatocytes.

Detailed explanation-4: -The reproductive system in females is responsible for producing gametes (called eggs or ova), certain sex hormones, and maintaining fertilized eggs as they develop into mature fetuses and become ready for delivery.
