Basic Bodily Functions

The body is composed of many systems and works both together and individually even without your personal training. These systems run with or without your consent to get into the gym or schedule health care to get a check up on them. Two specific systems that do this are the reproductive system and the endocrine system. The endocrine system is made up of many different glands and organs that produce and secrete hormones into the blood, their hormones go directly into the blood stream and they use them to regulate specific body functions.

One of the important functions of the endocrine system is to keep the body in homeostasis. Homeostasis is the state of equilibrium of the internal environment of the body so that all systems can function optimally. Its other functions include regulating body fluids, electrolytes, glucose, cellular metabolism, growth and the wake-sleep cycle.


The endocrine system is composed of many organs. These organs include the pituitary gland, thymus, pancreas, ovaries, testes, hypothalamus, pineal gland, thyroid gland, parathyroid and the adrenal gland. All of these glands and organs secrete important hormones that are in charge of many important actions in the body. An example of this is the ovaries. They secrete estrogen, testosterone and progesterone that affect and regulate puberty, menstruation and pregnancy.

The reproductive system is composed of the male and female sex organs. These organs have the ability to create more sex cells, combine with each other and procreate. The male reproductive system is composed of the external and internal genitalia. These include the scrotum, testes, epidydymides, penis, urethra, vas deferens, seminal vesicles, ejaculatory duct, prostate gland and bulbourethral glands. Its functions are to display the secondary male sexual characteristics, produce spermatozoa and deposit sperm inside the female.

The female reproductive system includes the internal and external genitalia as well. These structures are the ovaries, uterine tubes, uterus, vagina and the parts of the vulva. Its function is to display the secondary female sex characteristics, produce ova, conceive and bear children.

Both the male and female systems are constantly producing sperm and eggs to reproduces. These functions would not be able to work properly without being under the hormonal control of the endocrine system.
