ANATOMY

Detailed explanation-1: -Endocrine glands, situated at various sites around the body, and in specialised areas of the brain. The cells in these glands secrete specific chemicals called hormones. Hormones circulate around the body via the blood stream and modulate cellular or organ functions by binding with receptors in the target cells.

Detailed explanation-2: -The secretory products of endocrine glands are called hormones and are secreted directly into the blood and then carried throughout the body where they influence only those cells that have receptor sites for that hormone.

Detailed explanation-3: -Endocrine glands release hormones into the bloodstream. This lets the hormones travel to cells in other parts of the body. The endocrine hormones help control mood, growth and development, the way our organs work, metabolism, and reproduction. The endocrine system regulates how much of each hormone is released.

Detailed explanation-4: -On the other hand, endocrine glands secrete their substances directly into your bloodstream. They’re called ductless glands. Endocrine glands are part of your endocrine system, and they secrete hormones. Examples of endocrine glands include your pituitary gland, thyroid gland and adrenal glands.

Detailed explanation-5: -Protein hormones (or polypeptide hormones) are made of chains of amino acids. An example is ADH (antidiuretic hormone) which decreases blood pressure. Steroid hormones are derived from lipids. Amine hormones are derived from amino acids. 09-Oct-2013
