Given below are the events in human reproduction. Write them in correct sequential order.
Insemination, gemetogenesis, fertilisation, parturition, gestation, implanation.
The reproductive events in humans include
(i) Gametogenesis Formation of gemetes (sperm in males, ova in females).
(ii) Insemination Transfer of sperm into female reproductive tract.
(iii) Fertilisation Fusion of male and female gemetes.
(iv) Implantation Formation, development and then attachment of blastocyst to the uterine wall.
(v) Gestation Embryonic development inside female body.
(vi) Parturition Delivery of the baby.
The path of sperm transport is given below. Provide the missing steps in blank boxes.
The seminiferous tubules of the testes open into the vasa efferentia through rete testis. The vasa efferentia leave the testes and open into epididymis located along the posterior surface of each testes. The epididymis leads to vas deferens that ascends to the abdomen and loops over the urinary bladder.
It receives a duct from seminal vesicle and opens into urethra as the ejaculatory duct. These ducts store and transport the sperms from the testes to the outside through urethra.
