Q:

What is the function of gonads?

A:

According to the University of Rochester Medical Center, the primary functions of gonads in men and women are to secret hormones and to produce sperm and ova. In men, the gonads are the testes, and in women, the gonads are the ovaries. The gonads are considered endocrine glands because they release hormones.

The University of Rochester Medical Center states that the male gonads are responsible for releasing the male sex hormone testosterone. Testosterone helps the male body to mature its skeletal and muscular system, develop the reproductive organs, enlarge the larynx, grow body hair and increase the male sex drive. Testosterone is responsible for the development of male characteristics. The testes also produce and release sperm for sexual reproduction. Testosterone begins to work shortly after birth, tapers off during childhood and then continues to produce regularly from puberty throughout adulthood.

The University of Rochester Medical Center explains that the female gonads secrete estrogen and progesterone. Estrogen facilitates puberty, fat storage and the development of the uterus and vagina. Progesterone thickens the lining in the uterus to prepare for pregnancy. Both progesterone and estrogen control fertility and the menstrual cycle. The ovaries produce and release the ova, or egg, for sexual reproduction.

    What are testicles made of?

    A:

    The terms "testis" and "testicle" are often used interchangeably, though technically the testicle includes not only the testis but also the vas deferens and the epididymis, which are two tubular structures that serve to store and transport sperm. The testes themselves are made up of hundreds of tiny coiled tubules called "seminiferous tubules," which are the site of sperm cell generation.

    Why do women have more taste buds than men?

    A:

    Professor Tim Jacob of Cardiff University, writing for the Physiological Society, states that scientists believe that women have more taste buds than men because of evolution. Women are responsible for the health of their babies, so it was evolutionarily important for women to immediately recognize the tastes of toxins that might harm a child.

    What is the function of the gallbladder?

    A:

    The gallbladder's function is to store bile produced by the liver and release the bile into the small intestine during digestion in order to neutralize acids and break down fats. The fat in the digested food enters the small intestine, releasing cholecystokinin and triggering the gallbladder to release bile via the common bile duct.

    What is the function of the glomerulus?

    A:

    Glomeruli are the components that carry out the primary filtering action of the kidney. They connect on one side to the blood vessels that enter the kidney, and on the other side to fluid-collecting structures called tubules. The glomeruli accept the blood from the arteries and pass the filtered wastes and any extra water present into the tubules, according to the National Institute of Diabetes and Digestive and Kidney Diseases.
