1. It opens into the Vasa efferentia through rete testis.
2. It carries semen as well as urine.
3. It maintains temperature (2 – 2.5°C) lower than body temperature for sperm formation.
4. It leads to vas deferens that ascends to the abdomen.

विकल्प

• (i) - Prostrate, (ii) - Scrotum, (iii) - Testes, (iv) - Vas Deferens

• (i) - Seminiferous tubule, (ii) - Urethra, (iii) - Scrotum, (iv) - Epididymis

• (i) - Seminiferous tubule, (ii) - Vas Deferens, (iii) - Urethra, (iv) - Sertoli cells

Answer 1

(i) - Seminiferous tubule, (ii) - Urethra, (iii) - Scrotum, (iv) - Epididymis

Explanation:

1. Seminiferous tubule: The seminiferous tubules open into the vasa efferentia through the rete testis.
2. Urethra: The urethra is the duct that conveys urine from the bladder and receives the ejaculatory ducts to carry semen to the outside.
3. Scrotum: The scrotum maintains the testes at approximately 2 – 2.5°C below core body temperature to support spermatogenesis.
4. Epididymis: The epididymis leads into the vas deferens, which ascends into the abdomen.
