Endocrine System
In the human body there is an endocrine system, the function of the endocrine glands is to regulate behavior by means of certain activating secretions or hormones, which poured into the bloodstream, produce certain useful effects. The endocrine system is the set of glands and the hormones they produce that guides the development, growth, reproduction, and behavior of human beings and other animals. (Pettit, 2000, p. 413)
The function of the brain is to receive, mediate, and transmit nerve impulses. In a given social community, the function of the lawyer, judge, legislator, treasurer, is to perform the duties pertaining to his peculiar office. (Patrick, 1929, p. 108) the endocrine system regulates hormones that are directly related to the fight or flight response. Depending on the amount of specific hormones i.e. adrenaline released into one's system determines whether or not the individual will feel the need to take flight "run" or fight "stand" their ground.
Hormones, such as estrogen, androgen, and thyroid, travel through the body and cause specific responses when they are received by hormone receptors. Hormone (or endocrine) disruptors interfere with the normal functioning of the endocrine system. They can: mimic a natural hormone and thus fool the body into responding a certain way, interfere with the reception of hormones by hormone receptors, directly alter a hormone and impede its function, cause the body to overproduce or under produce natural hormones, or decrease or increase the number of hormone receptors. These effects are especially potent during prenatal development, when even minute exposure to hormones can severely disrupt the normal development process. Potential hormone disruption effects include abnormalities of the reproductive system, birth defects, behavioral changes, depressed immune systems, and lowered intelligence. (Pettit, 2000, p. 413)

The majority of individuals with a goiter will not likely realize it, until the goiter grows to a visible or palpable size, as a goiter may develop to enormous size prior to producing symptoms of compression.

This is called acute adrenal failure or an Addisonian crisis. It can be fatal if it isn't cared for. The indications may include: Pain in the abdomen, lower back or legs Severe vomiting and diarrhea Dehydration Low blood pressure Loss of consciousness (Addison's disease, 2010). Secondary adrenal deficiency takes place when the pituitary gland fails to manufacture adequate adrenocorticotropin (ACTH), a hormone that rouses the adrenal glands to produce cortisol. If ACTH production is too
Toxins are poisonous substances that can cause harm to human beings via one or more of its physiological systems. For example, DDT is a toxin used to kill insects but which also affects the human endocrine system. Tetrodotoxin is a toxin found in the venom of animals like frogs and pufferfish, but if it enters the human nervous system can cause paralysis or death. Mercury is a naturally-occurring element like
E. hypertrophy). In the elderly, this process is reverse. Hence, the functional reserve capacities of the skeletal muscles decline with age, largely due to diminished levels of physical activity. As a result daily tasks once taken for granted become progressively more difficult, and eventually impossible, to perform. In illustration, a great deal of muscle force is required to simply stand up or to climb stairs. Therefore, skeletal system is relying
Therefore, in cases unrelated to ileocecal valve malfunction, large distal bowel obstruction is a direct function of LaPlace's Law at the area of the cecum. For the same mechanical reason, the most frequent location of colonic perforation is also at the cecum because it is the area of the largest diameter, and therefore, most susceptible to rupture in comparison to areas smaller in diameter. 11.

Nervous System: In order to achieve its function, the nervous system is divided into two major parts i.e. The Central Nervous System (CNS) and Peripheral Nervous System (PNS). The central nervous system is basically made up of the brain and spinal cord and has the main function of receiving information from the body and sending out instructions. While the brain is protected by the skull, the spinal cord is guarded
