Given below is the schematic diagram of the sectional view of the human male reproductive system.
(a) Name the parts numbered 1-11.
(b) State the functions of the parts numbered 1, 2, 3, 5, 8 and 11.
a.
1 - Seminal vesicles
2 - Prostate gland
3 - Bulbourethral gland
4 - Epididymis
5 - Testis
6 - Scrotum
7 - Urinary bladder
8 - Vas deferens
9 - Erectile tissue
10 - Penis
11 - Urethra
b. Functions of
i. Seminal vesicles: They produce the fluid which serves as the transporting medium for sperms.
ii. Prostate gland: It produces an alkaline secretion which mixes with the semen and helps neutralise the vaginal acids.
iii. Bulbourethral gland: It produces a secretion which serves as a lubricant for the semen to pass through the urethra.
iv. Testis: It produces the male gamete sperm and the male sex hormone testosterone.
v. Vas deferens: They carry the sperms from the epididymis to the urethra.
vi. Urethra: It serves as an outlet for delivering the sperms into the vagina and also allow the passage of urine.
