GENERAL HISTOLOGY

Detailed explanation-1: -Endocrine glands make chemicals called hormones and pass them straight into the bloodstream. Hormones can be thought of as chemical messages. From the blood stream, the hormones communicate with the body by heading towards their target cell to bring about a particular change or effect to that cell.

Detailed explanation-2: -These highly selective transport proteins include sex hormone binding globulin (SHBG), which carries estradiol and testosterone; corticosteroid binding globulin (CBG), which carries glucocorticoids; and thyroid binding globulin (TBG) and transthyretin (TTR), both of which carry thyroid hormones.

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.
