body is found in the thyroid gland‚ but is found also in the blood and muscles. The body contains approximately 20 to 30 mg of iodine which is mostly stored in the thyroid gland located in front of the neck. Food sources: Milk is the major source‚ fish from the sea‚ ‚ shell fish‚ fish liver oil‚ sunflower seeds‚ yogurt(low fat) egg‚ strawberries‚ mozzarella cheese and iodized salt. Seaweed is also a good source of iodine. Function : Help ensure proper thyroid gland functioning. Keeps hair‚ skin

BSC2085 Anatomy-Physiology 1 Exam 2 Study Guide‚ Chapters 5 & 6 There are only four primary tissue types found in adult organs; epithelial‚ connective‚ nervous‚ and muscular tissue. Epithelial tissue lines body cavities‚ covers the body surface‚ and forms the lining of many organs. Connective tissue serves in most cases to bind organs to each other. Nervous tissue and muscular tissue are considered excitable tissues because they are very sensitive to outside stimuli. A simple epithelium consists

of well known environmental contaminants‚ such as dioxin‚ PCBs and DDT‚ can affect hormone levels. Hormones are produced by the endocrine system as regulators of biological function in target organs. Because hormones play a critical role in early development‚ toxicological effects on the endocrine system often have an impact on the reproductive system. The term endocrine disruptor is used to describe chemicals that can mimic hormones and may either enhance or counteract their effects. It has been

Lab 28B: Endocrine System Physiology Computer Simulation Introduction The endocrine system is the second greatest control system of the body and has many effects on the tissues and organs. The thyroid gland‚ which is a part of the endocrine system‚ releases a hormone that maintains metabolism. This hormone is thyroxine. Thyroxine production is controlled by thyroid stimulating hormone‚ which is released by the pituitary gland. TSH stimulates the thyroid gland to produce thyroxine. In

Human Endocrine System A system of glands and cells that make hormones that are released directly into the blood and travel to tissues and organs all over the body. The endocrine system controls growth‚ sexual development‚ sleep‚ hunger‚ and the way the body uses food. [pic] The human endocrine system modulates several processes of the body by the function of hormones. The endocrine system secretes hormones that control how bodily functions work. Thus‚ the human endocrine system watches

Iodine is an element that is critical for normal function of the thyroid gland‚ which is a key regulator of the body’s basic metabolic rate. Iodine is a micronutrient‚ meaning we require only small amounts of it. For example‚ adults need about 150 micrograms of iodine in the form of iodide ion per day. However‚ an insufficient supply of iodide via diet and drinking water causes the non-cancerous enlargement of the thyroid gland known as goiter. Prolonged lack of iodide can lead to loss of thyroid function
