Male Reproductive system v/s female reproductive system
Answers
Explanation:
Reproduction in Human Beings
MALE REPRODUCTIVE SYSTEM
1.Testes: Male humans have two testes. They are situated in a bag of skin known as the scrotum. Scrotum lies outside the pelvic cavity.
2.Sperm Duct: These are thin ducts that arise from the testes.
3.Prostrate Gland: This gland is an accessory gland in males which pours its secretions into the sperm duct along with the seminal fluid from the testes and into the penis.
4.Urethra: Functions as a common pathway for the seminal fluid and urine in males. It is longer in males and shorter in females.
5.Penis: Is an organ which lies outside the body and functions to eliminate both urine and semen.
The testes are the primary organs of male reproduction. They are responsible for producing the male gamete known as the sperm by a process called as spermatogenesis. This occurs in the seminiferous tubules of the testes. The testes are also responsible for secreting the male reproductive hormone testosterone.
Laydig Cells of the testes synthesizes Testosterone. The hormone testosterone not only helps in the formation of the sperm but also in the development of secondary sexual characters in males such as deepening of the voice, facial and pubic hair during puberty.
FEMALE REPRODUCTIVE SYSTEM
The female reproductive system in humans in entirely within the pelvic cavity. It comprises of the following structures:
1.Ovaries: They give rise to the female gamete or the egg. Each ovary releases one egg alternatively each month. Ovulation is the process of release of an egg from either one of the ovaries.
2.Fallopian tubes: Also known as the oviducts, these tubes arise from the ovaries and end at the uterine fundus. Their function is to carry the egg once it is released into the uterus where it can fuse with the male sperm.
3.Uterus: It is a large muscular organ that is present in the pelvic cavity. The uterus is the region of action during the menstrual cycle, fertilization and the development of the fetus.
4.Cervix: Is a circular muscle ring that is present towards the lower end of the uterus that dilates at the time of delivery of the baby.
5.Vagina: Is a muscular tube-like structure that is present at the lower end of the cervix and leads towards the outside of the female body. The vagina functions as the pathway for the penis to enter the female body and deposit the sperms which then swim their way to the uterus to fertilize with the female egg.
6.Urethra: It is shorter than that found in males. In females, the urethra serves only for passage of urine.
The egg is formed under the influence of both female sex hormones estrogen and progesterone. This process is known as Oogenesis.
