Quiz 19: The Reproductive System

Biology

Gametes are reproductive cells. Examples of gametes are eggs and sperms. Females produce eggs. Males produce sperms. Gametes have only one set of chromosomes. Body or somatic cells have two sets of chromosomes. Therefore, gametes are haploids. Somatic cells are diploids. At fertilization, one sperm unites with an egg. The fertilized egg has two sets of chromosomes. Humans are produced from the fertilization of one egg and one sperm. Hence, the father contributes one set of chromosomes. The mother contributes one set of chromosome. Each human has two sets of chromosomes. Gametes are haploid cells. The fertilization of two gametes produces a diploid organism. Human reproduction results from the fertilization of an egg and a sperm. Eggs and sperms are human gametes.

The human reproductive system is responsible for perpetuating the human species. Females have a different reproductive system than males. However, the reproductive system of both males and females share several similarities. A reproductive system has four basic components. A reproductive system has gonads. Gonads are organs. Gonads produce gametes. Female gonads produce eggs. Male gonads produce sperms. A reproductive system has ducts. Ducts are tubes. In females, the ducts conduct eggs from the ovary to the uterus. In males, the ducts conduct sperms from the testis to the urethra. Different ducts have different names. Ducts transport gametes and other substances. A reproductive system has accessory glands and organs. The accessory glands and organs serve the function of that specific body system. The accessory glands and organs of the reproductive system serve the functions of the reproductive system. The accessory glands and organs secrete fluids into the ducts. The fluids are meant to facilitate reproduction. A reproductive system has perineal structures. Perineal structures are also called external genitalia. The perineal structures differentiate males and females. Males have different perineal structure from females. Human reproductive system shares four basic components. Each reproductive system has gonads, ducts, accessory glands, accessory organs, and perineal structures. Male and female reproductive systems are composed of these four basic components.
