The mind and body communicate biologically in three ways. Those three ways are autonomic nervous system (ANS)‚ endocrine system and the immune system. The autonomic nervous system is a group of nerves that control anatomical processes like the heart rate‚ blood pressure‚ breathing and the functions of the gastrointestinal‚ sweating and elimination. These things that are happening in our bodies right now without us knowing about it. We definitely wouldn’t have control of any of these‚ except for

is an essay question that is based on content presented in a BIO 105 lesson on Environmental Health and Toxicology: What are endocrine disruptors? How do they work on pests? Why are they a problem for humans? Have they been banned? Why or why not? In the example essay question above‚ one element that could potentially require a citation is the definition of “endocrine disruptor.” Ideally‚ the department would like to see students

travels through the vagina and cervix into the uterus for conception of the ovum. Upon successful fertilization and implantation‚ this process is known as pregnancy in humans. Then we have the Endocrine glands. They are glands of the endocrine system that secrete hormones‚ directly into the blood. The main endocrine glands are the pituitary (anterior and posterior lobes)‚ thyroid‚ parathyroid‚ adrenal (cortex and medulla)‚ pancreas and gonads. The pituitary gland is attached to the hypothalamus of the

amount of calcium in human body. In such a way‚ thyroid generates calcitonin‚ whereas parathyroid glands regulate the level of calcium in human body through production of hormones. 4. The hypothalamus’ function is to link the nervous system to the endocrine system via pituitary gland. The hypopthalamus is responsible for certain metabolic processes‚ including synthesizing secreting certain neurohormones‚ which are called hypothalamic-releasing hormones‚ which stimulate or inhibit secretion of pituitary

always leads to another systems function. If one organ becomes ineffective/damaged‚ then that person may not function well and end up passing away. There are eleven organ systems within the human body: integumentary‚ skeletal‚ muscular‚ nervous‚ endocrine‚ circulatory/cardiovascular‚ lymphatic‚ respiratory‚ digestive‚ urinary‚ and reproductive. The nervous system sends messages by electrical pulses telling all the organs what to do like the brain. When you digest food/nutrients your digestive system
