QuestionAnswer 1Answer 2
ENDOCRINE is a collection of glands that produce harmones which help regulate the bodys growth, metabolism, and sexual development and function. The harmones are released into the bloodstram and transported to tissues and organs throughout the body.
Endocrinology the study of the chemical communication system that provides the means to control a large number of phusiologic processes.
Endocrine "communication" system involves the hypothalamus, pituitary gland, other hormone producing cells or glands, hormones and receptors. the major driving forces of the endocrine ststem are the hypothalamus and the pituitary gland.
the BRAIN part of the brain stem known as the hypothalamus contrils the activity of the pituitary gland.
HYPOPHYSIS another name for the pituitart gland it is attatched to the base of the hypothalamus in the brain. compoosed of ANTERIOR LOBE AND POSTERIOR LOBE
PANCREAS for example: secretes digestive enzymes.
Adrenal Glands divided into 2 regions: secrete hormones that influence the bodys metabolism, blood chemicals, and body characteristics as well as influence the part of the nervous system that is involved in the response and defense against stress.
Hypothalamus activates and controls the part of the nervous system tha controls involuntary body functions. the hormonal system and many body functions such as regulating sleep and stimulating appetite.
Ovaries and testicles secrete hormones that influence female and male characteristics respectively
Pancreas secrete hormone(insulin) that controls the use of glucose by the body
Parathyroid glands secrete hormone that maintains the calcium level in the blood '
Pineal body involved with daily biological cycles

Pituitary Gland produces a number of different hormones that influence various other endorine glands.
Thymus gland plays a role in the bodys immune system
Thyroid gland produces hormones that stimulate body heat production,bone growth and the bodys metabolism.
Hormones are the chemicals that take the "messeges" to the cells through the bloodstream hormones transfer information and instructions feom one set of cells to another.
There are many factors that can affect the level of hormones in the body at any time AGE, STRESS, INFECTION,AND CHANGES IN THE BALANCE OF FLUIDS AND MINERALS IN BLOOD.
The Hpothylamus is in charge of controlling many body functuons especially a number of harmones important to the female mentural cycle, pregnancy birth, and location(milk production)
Set point Dynamic vital statistics such as blood pressure, body temperature, fluid and electrolyte balance and weight are held to a given predertermined value.
The Hypothalamus produces harmones known as releasing factors. releasing factors are sent to the anterior lobe via small blood vessels, which then connect to hypothalamus to the anterior lobe of the pituitary gland. they hypothalamus will direct the master pituitary gland to release these two hormones oxytocin and antidiuretic harmone (ADH)
Negative Feedback the mechanism that controls the release of the tropic stimulating hormones from the anterior pituitary gland. When the egg has matured, the ovary releases negative feedback to the hypothalamus, which tells the brain that the "deed" is done.
Thyroid Gland is situated just below the ADAMS APPLE or larynx. it is a small gland, weighing less than one once located in the front of the neck.
Isthumus it is made up of two halves called lobes that lie along the windpipe and are joined together by a narrow band of throid tissue.
Two types of cells that makes up thryoid tissue; follicular cells, and parafollicular cells. The thyroid needs iodine to produce the hormones.
The thyroid is a very important gland that affects parts of the body functions that regulate growth such as follows thermogenesis, growth and development, nervous system, and the heart
The richest sources of iodine are seafoods and seaweeds(especially kelp) in the United States the primary source of iodine is IODIZED SALT.
T3 AND T4 are then released into the bloodstream and are transpored throught out the body, where they control metabolism.
Adrenal Glands are located on the upper part of the kidney.
Adrenal cortex secretes two types of hormones, which are divided into two main classes GLUCOCORTICOIDS, AND MICROCORTOCOIDS.
Nervous System is considered the mass communicator of the human body, and HORMONES are the chemicals that do the communicating. during pregnancy the placenta acts as an endocrine gland.
