Transcript of Endocrine System

Parathyroid Career supported by rich oxegen blood produces a hormine called parathromone The Endocrine System
Pineal Gland Hypothalamus Current Research, Technology,
and Careers Organotherapy (old) Assisted Reproductive Technologies (ART) Endocrinology
-branch of science that studies
endocrine glands, hormones, and hormone-like substances Endocrinologists
Salary: $112,000
(in Houston) More than 10 years of
experienced required Parathyroid Glands Thyroid Glands Thymus Adrenal Gland Pancreas Ovaries Testis One on the tip of
both Kidneys -Regulated by the sympathetic nervous system Adrenaline &
Nonadrenaline Diseases and Disorders Addison's Disease -hormone secretion by adrenal cortex is impaired Cushing's Syndrome -excess of chronic glucocorticoid Two Parts: Cortex &
Medulla Controls the Pituitary Gland
and makes several hormones Holds Pituitary Gland Works mainly with
the Pituitary Gland Pituitary Gland Controls all other endocrinal glands Does not contain any hormone-making cells Stores
-antidiuretic &
oxytocin hormones Shared Diseases and Disorders Acromegaly (rare) -causes body parts to become thicker Gigantism -body parts growing excessively Dwarfism (rare) -too little growth in body parts 2 organs in 1 5-6 inches
3 ounces Secretes insulin and glucagon Alpha, Beta, and Delta cells Diseases and Disorders Pancreatitis Pancreatic Cysts Pancreatic Tumors -very hard to diagnose Islet Cell Tumors Gonad Produce: -estrogens
-progesterone
-relaxin Produce steriod sex hormones that stimulate reproductive processes Found only in Females Deseases and Disorders Ovarian Cysts Ovarian Cancer Gonad Only found in Males Produce Androgens -testosterone
-androstenedione
-androsterone
-adrenosterone In early childhood years the Pineal Gland releases large amounts of Melatonin Stimulates the growth of Gonads "biological clock" Primary Amenorrhea True Sexual Precocity True Sexual Precocity Disorders and Diseases 2 lobes
(right & left) 3-4 millimeters wide Ductless Glands Controlled by Pituitary Gland Hormones Secreted -thyroxine or tetraiodothyronine
-triiodothyronine Important to Human Growth and Metabolism Diseases and Disorders Congenital Hypothyroidism Growth Retardation Mental Deficiency Produces and processes thymocytes Important to the Immune System Decreases in size after puberty Functional throughout whole life 2 pairs Secrete Parathormone Regulates the amounts of Calcium and Phosphorus in the blood Hypoparathyroidism Hyperparathyroidism Diseases and Disorders Caring for Your Endocrine System No unnecessary hormone supplements Eat well to prevent Diabetes Minimal Stress Systems that Work
with the Endocrine
System Immune System Reproductive System Circulatory System Digestive System The Endocrine System is vital to sustain life. Endocrine Glands and Organs work to maintain homeostasis throughout the body by producing hormones and working with many other bodily systems. Interesting Facts
About the
Endocrine System Also, the Endocrine System is responsible for producing 30 distinct hormones. All these hormones have very distinct jobs to do.

The Endocrine System aids the immune system by helping the body build resistance to disease.

The Endocrine System has a hand in almost all functions of the human body. Nervous System The adrenal glands release hormones that help the bidy prepare and deal with stress
