What is reproductive system in zoology?
The reproductive system of an organism, also known as the genital system, is the biological system made up of all the anatomical organs involved in sexual reproduction. Many non-living substances such as fluids, hormones, and pheromones are also important accessories to the reproductive system.
Does sperm and urine come from the same place?
No. While sperm and urine both pass through the urethra, they can’t come out at the same time.
How the sperm is produced?
There is a system of tiny tubes in the testicles. These tubes, called the seminiferous tubules, house the germ cells that hormones — including testosterone, the male sex hormone — cause to turn into sperm. The germ cells divide and change until they resemble tadpoles with a head and short tail.
What are the three main functions of the male reproductive system?
- They produce, maintain and transport sperm (the male reproductive cells) and semen (the protective fluid around sperm).
- They discharge sperm into the female reproductive tract.
- They produce and secrete male sex hormones.
Where is sperm stored?
A long tube that is located near each testicle. The epididymis is the tube which moves the sperm from the testicles. Vas deferens. This is a tube in which the sperm is stored and it carries the sperm out of the scrotal sac.

In this early stage, the embryo develops a yolk sac, which provides its first nutrients. But as the tiny being grows, it will turn to its host (you) for sustenance.
How pregnancy happens step by step?
- Sperm transport — The sperm must be deposited and transported to the site of fertilization.
- Egg transport — Ovulation must occur and the egg must be “picked up” by the tube.
- Fertilization and embryo development — Union between the sperm and egg must result.
What is the function of the reproductive system in animals?
animal reproductive system, any of the organ systems by which animals reproduce. The role of reproduction is to provide for the continued existence of a species; it is the process by which living organisms duplicate themselves.
