Discuss the adaptations of the female reproductive system of humans - KCSE Biology Essays

Elastic uterine walls; to expand so as to accommodate the growing foetus;

Muscular foot of the pelvis and bladder support the weight of the growing foetus;

Funnel-shaped ends of the oviduct; direct the ova released to the uterus;

Muscular uterine walls; contract and relax to expel the foetus at birth;

Long vaginal canal; allow sufficient entry of penis to avoid wastage of sperms;

The two ovaries maximize chances of releasing ovum after every circle (28 days);

Ovaries are well vascularised/have good blood supply; to ensure nourishment of cells involved in oogenesis (primordial mother/germ cells) or egg formation;

High number of potential mother cells; ensures maximum number of ova which develop to maturity;

Plenty of yolk in egg cells; which nourish the foetus before the placenta becomes functional;

The vitelline membrane of the ovum thickens after fertilization; preventing further entry of sperms;

The oviduct wall is able to contract; in order to facilitate movement of ovum down the oviduct;

Has cilia to waft the ovum forward; wall of the vagina/vulva produce mucus; to lubricate the penis during copulation;

Clitoris; has many nerve endings; to provide maximum stimulation during copulation for maximum ejaculation and faster movement of spermatozoa;
