Hormones work by affecting Target Organs
testes and ovaries
target organs
The membrane proteins that attach to specific hormones such as insulin are called receptor proteins.
A group of tissues that work together to perform a specific function is called an organ. Tissues are made up of a group of cells that are performing the same functions.
It is called Hormones
That would called an 'Organ'.
Yes. Sweat glands are organs even though they are in the skin which is also an organ.
Because hormones have specific hormone binding sites to act
A hormone is a chemical substance produced by the specially formed tissues are called endocrine glands.
Hormones are chemical messengers that are secreted by the endocrine glands into the blood. Hormones are transported via the bloodstream to reach specific cells, called target cells, in other tissues. They produce a specific effect on the activity of cells that are remotely located from their point of origin.
They are the target organs. Hormones act on the target organs
The membrane proteins that attach to specific hormones such as insulin are called receptor proteins.
Endocrine glands release chemicals directly into the bloodstream. These hormones are then carried by the circulatory system to their target tissues.
Prostaglandins are modified fatty acids that are produced by a wide range of cells. They generally affect only nearby cells and tissues, and thus are known as "local hormones."
Endocrine glands secrete chemical messengers called hormones. These chemicals are secreted directly into the bloodstream, where they are carried by the circulatory system to target tissues throughout the body.
Hormones
That's called an "organ."
hormones.
Hormones are a kind of biochemical messengers. Most hormones are chemical substances produced by specialized tissue formations called endocrine glands. The substances are secreted directly into the bloodstream, other body fluids, or into adjacent tissues. The purpose of hormones is to regulate metabolic activity of some other organs or tissues of the body.Three different ways hormones act:1. Alter the rate of synthesis of your cellular protein.2. Change the rate of enzyme activity.3. Change the rate of transport of nutrients through the cell wall.
