The reproductive system ensures the survival of the species. Other systems in the body, such as the endocrine and urinary systems, work continuously to maintain homeostasis for the survival of the individual. An individual may live a long, healthy, and happy life without producing offspring, but if the species is to continue, at least some individuals must produce offspring.

hymen
The hymen is a thin, fleshy tissue that is at the opening of your vagina.
The hole in your hymen is big enough for your period blood to come out and for you to be able to use tampons easily. Some people are born with so little hymenal tissue that it looks like they don’t have a hymen at all. In rare cases, people have hymens that cover the whole vaginal opening or hymens with very small holes. In these cases, they may need to see a doctor for a minor procedure to remove the extra tissue. Like other parts of our bodies, everyone has a slightly different hymen.
