Urinary+System

__//**Urinary System**//__ The kidneys produce urine. This is their main purpose for existing in the body, once they have produced this, their next job is to send it to the bladder. The kidneys produce urine, then the urteres transports the urine to the bladder, the bladder stores the urine, and finially the urethra gets rid of the urine by passing it outside the body This is considered to be any drug that evaluates the rate of bodily stool excretion. ADH is secreted by the posterior pituitary depending on the osmolarity of the blood. If a person intake of water is low, ADH is secreted by the posterior pituitary and water moves from the distal concoluted tubule, and also a collecting duct, into the blood. First Define Homeostasis. Then in your words as much as possible, describe how the kidneys help maintain homeostasis in the various systems of the human body. Endocrine System** Homeostasis is is the process of maintaning your normal conditions in cells or an arganism that by means of self regulating mechanisims. Endocrine System is the organ system that is involved in the coordination of the body's activities. It also uses hormones as chemical signals secreted into the bloodstream. The Kidneys have the main purpose of producing and transportign urine in the body. By maintaning this, they are playing a very key role in helping your body stay as normal as it can possibly be. The Urinary System is is incharge of the kidneys which are an aid to all other systems since they get rid of nitrogens waste and help to maintain the water to sault balance in your body. The other systems that are aided by the Urinary System are; Cardiovascular System, Digestive System, Muscular System, Nervous System, Respiratory System, Endocrine System, and the Integumentary System. It's an Endocrine gland that resides in the neck and produces several important hormones including thyroxine, triiodothyronine, and calcitonin. Adrenaline is something that the body releases when you become very excited or scared. It has to do this in order to keep your heart rate semi under control while you are experienceing this abnormal mindset.
 * In your words: explain the four ways the kidneys help maintain homeostasis (a stable internal environment) for the human body (pp.188-189).**
 * Define the role as stated on page 188 of the kidneys, ureters, urinary bladder, and urethra.**
 * Define Diuretic and name a couple diuretics. (may need to look this up on the internet)**
 * Define the role of the hormone ADH. (What does it stand for, where is it produced and what does it signal?) p. 198**
 * On page 201 the book shows how important the kidneys are to maintain homeostasis.
 * Pituitary gland (p.300-301) Describe ADH and its role in the body. Describe Growth Hormone and its role in the body. Describe pituitary dwarfism and acromegaly.**                 ADH is secreted by the posterior pituitary depending on the osmolarity of the blood. If a person intake of water is low, ADH is secreted by the posterior pituitary and water moves from the distal concoluted tubule, and also a collecting duct, into the blood.
 * Thyroid gland (p.303): Describe these problems and possible treatments with the thyroid gland: simple goiter, congenital hypothyroidism, myxedema, expophthalmic goiter.**
 * Adrenal gland (p.305) What is the role of epinephrine (adrenaline)?**
