Unique for its role in human reproduction, a gamete is a specialized sex cell carrying 23 chromosomes—one half the number in body cells. At fertilization, the chromosomes in one male gamete, called a sperm or spermatozooncombine with the chromosomes in one female gamete, called an oocyte. The function of the male reproductive system Figure 1 is to produce sperm and transfer them to the female reproductive tract.
In simple terms, reproduction is the process by which organisms create descendants. This miracle is a characteristic that all living things have in common and sets them apart from nonliving things. But even though the reproductive system is essential to keeping a species alive, it is not essential to keeping an individual alive. In human reproduction, two kinds of sex cells or gametes are involved.
Reproduction is the process by which organisms make more organisms like themselves. But even though the reproductive system is essential to keeping a species alive, unlike other body systems, it's not essential to keeping an individual alive. In the human reproductive process, two kinds of sex cells, or gametes pronounced: GAH-meetzare involved.
A tiny sperm from dad breaks through the surface of a huge egg from mom. In nine months, a new son or daughter will be born. Like most other multicellular organisms, human beings reproduce sexually.
The male reproductive system includes the scrotum, testes, spermatic ducts, sex glands, and penis. These organs work together to produce sperm, the male gamete, and the other components of semen. These organs also work together to deliver semen out of the body and into the vagina where it can fertilize egg cells to produce offspring.
The site navigation utilizes arrow, enter, escape, and space bar key commands. Up and Down arrows will open main level menus and toggle through sub tier links. Enter and space open menus and escape closes them as well.
Humans are sexual, meaning that both a male and a female are needed to reproduce. Each is equipped with specific organs capable of producing specific cells needed to procreate. The average age of puberty for males is around
The major function of the reproductive system is to ensure survival of the species. Other systems in the body, such as the endocrine and urinary systems, work continuously to maintain homeostasis for 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. These functions are divided between the primary and secondary, or accessoryreproductive organs.
