The+Endocrine+System+By+Natalia+Gavranic

The foundations of the endocrine system are the hormones and glands. As the body's chemical messengers, hormones transfer information and instructions from one set of cells to another. Although many different hormones circulate throughout the bloodstream, each one affects only the cells that are genetically programmed to receive and respond to its message. Hormone levels can be influenced by factors such as stress, infection, and changes in the balance of fluid and minerals in blood. A gland is a group of cells that produces and secretes, or gives off, chemicals. A gland selects and removes materials from the blood, processes them, and secretes the finished chemical product for use somewhere in the body. Some types of glands release their secretions in specific areas. For instance, exocrine glands, such as the sweat and salivary glands, release secretions in the skin or inside of the mouth. Endocrine glands, on the other hand, release more than 20 major hormones directly into the bloodstream where they can be transported to cells in other parts of the body. The major glands that make up the human endocrine system are the hypothalamus, pituitary, thyroid, parathyroids, adrenals, pineal body, and the reproductive glands, which include the ovaries and testes. The pancreas is also part of this hormone-secreting system, even though it is also associated with the digestive system because it also produces and secretes digestive enzymes. Although the endocrine glands are the body's main hormone producers, some non-endocrine organs — such as the brain, heart, lungs, kidneys, liver, thymus, skin, and placenta — also produce and release hormones By Natalia Gavranic Continue  [|Movie: The Endocrine System]   [|Type 1 Diabetes: What Is It?]   [|Type 2 Diabetes: What Is It?]   [|What Are Glands?]   [|Your Endocrine System]   [|Endocrine System]  <span style="color: #555555; display: none; font-family: 'Verdana','sans-serif'; font-size: 6pt; mso-bidi-font-family: 'Times New Roman'; mso-fareast-font-family: 'Times New Roman'; mso-fareast-language: EN-AU; mso-hide: all;"> [|Growth Problems] <span style="color: #555555; display: none; font-family: Symbol; font-size: 10pt; mso-bidi-font-family: Symbol; mso-bidi-font-size: 6.0pt; mso-fareast-font-family: Symbol; mso-fareast-language: EN-AU; mso-hide: all; msobidifontfamily: Symbol; msobidifontsize: 6.0pt; msofareastfontfamily: Symbol; msofareastlanguage: EN-AU; msohide: all; msolist: Ignore;"> <span style="color: #555555; display: none; font-family: 'Verdana','sans-serif'; font-size: 6pt; mso-bidi-font-family: 'Times New Roman'; mso-fareast-font-family: 'Times New Roman'; mso-fareast-language: EN-AU; mso-hide: all;"> [|Metabolism] <span style="color: #555555; display: none; font-family: Symbol; font-size: 10pt; mso-bidi-font-family: Symbol; mso-bidi-font-size: 6.0pt; mso-fareast-font-family: Symbol; mso-fareast-language: EN-AU; mso-hide: all; msobidifontfamily: Symbol; msobidifontsize: 6.0pt; msofareastfontfamily: Symbol; msofareastlanguage: EN-AU; msohide: all; msolist: Ignore;"> <span style="color: #555555; display: none; font-family: 'Verdana','sans-serif'; font-size: 6pt; mso-bidi-font-family: 'Times New Roman'; mso-fareast-font-family: 'Times New Roman'; mso-fareast-language: EN-AU; mso-hide: all;"> [|Thyroid Disease] <span style="color: #555555; display: none; font-family: Symbol; font-size: 10pt; mso-bidi-font-family: Symbol; mso-bidi-font-size: 6.0pt; mso-fareast-font-family: Symbol; mso-fareast-language: EN-AU; mso-hide: all; msobidifontfamily: Symbol; msobidifontsize: 6.0pt; msofareastfontfamily: Symbol; msofareastlanguage: EN-AU; msohide: all; msolist: Ignore;"> <span style="color: #555555; display: none; font-family: 'Verdana','sans-serif'; font-size: 6pt; mso-bidi-font-family: 'Times New Roman'; mso-fareast-font-family: 'Times New Roman'; mso-fareast-language: EN-AU; mso-hide: all;"> [|Type 1 Diabetes: What Is It?] <span style="color: #555555; display: none; font-family: Symbol; font-size: 10pt; mso-bidi-font-family: Symbol; mso-bidi-font-size: 6.0pt; mso-fareast-font-family: Symbol; mso-fareast-language: EN-AU; mso-hide: all; msobidifontfamily: Symbol; msobidifontsize: 6.0pt; msofareastfontfamily: Symbol; msofareastlanguage: EN-AU; msohide: all; msolist: Ignore;"> <span style="color: #555555; display: none; font-family: 'Verdana','sans-serif'; font-size: 6pt; mso-bidi-font-family: 'Times New Roman'; mso-fareast-font-family: 'Times New Roman'; mso-fareast-language: EN-AU; mso-hide: all;"> [|Type 2 Diabetes: What Is It?] __<span style="color: blue; display: none; font-family: 'Verdana','sans-serif'; font-size: 9pt; mso-bidi-font-family: 'Times New Roman'; mso-bidi-font-size: 11.0pt; mso-fareast-font-family: 'Times New Roman'; mso-fareast-language: EN-AU; mso-hide: all;">Sign up for our free weekly eNewsletters here __<span style="color: #555555; font-family: 'Verdana','sans-serif'; font-size: 6pt; mso-bidi-font-family: 'Times New Roman'; mso-fareast-font-family: 'Times New Roman'; mso-fareast-language: EN-AU;">
