Describe in brief the role of (i) testis (ii) seminal vesicle,(iii) vas deferens,(iv) ureter and (v) prostate gland in human male reproductive system.

Role of human male reproductive system is as follows:

(i) Testis:

These are the main reproductive part in male reproductive system and the formation of germ-cells or sperms takes place in testis. These are located outside at the abdominal cavity in Scrotum due to low temperature requirement than the body temperature for the sperm formation. These are responsible for secretion of hormone known as testosterone.

(ii) Seminal vesicles:

These are the glands which add their secretions so that sperms are now in a fluid and can be easily transported and this fluid also provides nutrients

(iii) Vas deferens:

The sperms are delivered through vas deferens which unites with a tube coming from the urinary bladder.

(iv) Ureter:

These are a pair of long, narrow, thin walled and tubular structure which starts from kidneys and open in urinary bladder. These are responsible for conducting urine from kidneys to urinary bladder.

(v) Prostate gland:

These are the glands which along with seminal vesicles, add their secretions so that sperms are now in a fluid and can be easily transported and this fluid also provides nutrients
