Vas Deferens
It is a tubular structure of the male reproductive system that transports sperm. The testis opens into vas efferentia and then the epididymis. The epididymis leads to a partially-coiled tube called the vas deferens, which loops over the urinary bladder. It later receives the duct from the seminal vesicle and into the urethra as the ejaculatory duct. The vas deferens helps in transporting the sperm from the epididymis to the ejaculatory duct.
The rete testis, vas efferentia, epididymis and the vas deferens are the accessory male sex organs.
Fallopian Tube
A fallopian tube or oviduct is a 10-12 cm long tube that extends from the ends of the ovary to the uterus. This long tube is actually composed of four parts – The infundibulum, along with fimbriae, the ampulla and the isthmus. The part near the ovaries is the infundibulum which possesses finger-like projections called the fimbriae. This projection helps in the collection of the ovum. The infundibulum leads to a wider ampulla and finally a tube called the isthmus. This isthmus is the major section of the fallopian tube that links to the uterus.
Difference between Vas Deferens and Fallopian Tube
Vas Deferens |
Fallopian Tube |
|
It is a tubular structure in the male reproductive system that carries sperms. |
It is a long tube in the female reproductive system that helps in the movement of female gametocytes. |
|
It is a comparatively longer tube that measures about 30 cm. |
This fallopian tube is approximately about 10-12 cm long. |
|
It carries the sperms from the epididymis to the ejaculatory duct. |
It carries the female gametocytes for the fertilisation process. |
Frequently Asked Questions
What are the female accessory sex organs?
The uterus, the fallopian tube or oviducts and the vagina form the accessory female sex organs.
What is rete testis?
It is a network of small interconnecting tubes in the testicle. This rete testis transports sperms from the seminiferous tubules (within testes) to the vasa efferentia.
What is a uterotubal junction?
The uterotubal junction is found between the uterus and the oviduct or fallopian tube. It acts as a selective passage for sperm with normal morphology. Usually, the contraceptive methods block this junction to avoid pregnancy.
What is vas efferentia?
The vasa efferentia or the efferent duct connects the rete testis with the epididymis. It is a very small tube compared to the vas deferens. This efferent duct makes a pathway to carry the sperms.
