Question

What are the differences between a vas deferens and a fallopian tube?

Answer 1

Vas deferens `to` Male reproductive system
Follapian tube `to` Female reproductive system.

Explanation:

In a bit detail now:

• Vas deferens is about `45cm` long duct of male reproductive tract. Spermatids produced in the testes after meiotic division differentiate into mature sperms. These sperms are then transferred to vas deferens via its first highly convoluted part i.e epididymis. The vas deferens then transport the sperms to the ejaculatory duct and urethra.

• Follapian tube also known as uterine tube is about `10cm` long duct of female(mammalian) reproductive tract. Fertilization of egg takes place at proximal end of follapian tube. The fertilized egg stays in follapian tube for `3−4` days. Hence it provide protection to the egg released from the ovary and serve as carrier for its safe transportation to the uterus.

Answer 2

Vas deferens is part of male reproductive system, while fallopian tube is part of female reproductive system.

Explanation:

There are paired gonoducts for passage of gametes from gonads in vertebrates. Humans are no exception.

1. Vas deferens is male gonoduct which carries sperms away from testes for ejaculation. Vas deferens collects secretion from seminal vesicle and becomes ejaculatory duct before draining in male urethra.
2. Fallopian tube is female gonoduct which receives ova as ovulation occurs in ovary. Fertilisation also takes place in fallopian tube and early embryo gradually reaches uterine cavity from the tube.
3. Vas deferens is lined by ciliated pseudostratified epithelium, while fallopian tube is lined by ciliated columnar epithelium.
4. Vas deferens develops from embryonic Wolffian duct and fallopian tube develops from embryonic Mullerian duct.
5. Vas deferens travels from scrotal sac to abdominal cavity. Fallopian tube is entirely present in abdominal cavity.
6. Length of vas deferens in adult male is about 30 cm. Length of fallopian tube in adult female is about 12 cm.
7. Diameter of vas deferens is about 1.5 to 2.5 mm. Fallopian tube is wider (1 cm) near ovary but very narrow (1 mm) when joins the uterus.
8. Both vas deferens and fallopian tube could be cut and tied in surgical procedure for sterilisation. This is called ligation: vasectomy in male and tubectomy in female.
