NEET BIOLOGY

Detailed explanation-1: -The liver is the target organ for both adrenaline and insulin. Target organs and target cells are specific organs and cells upon which hormones act and produce their effects.

Detailed explanation-2: -Hormones travel throughout the body, either in the blood stream or in the fluid around cells, looking for target cells. Once hormones find a target cell, they bind with specific protein receptors inside or on the surface of the cell and specifically change the cell’s activities.

Detailed explanation-3: -Hormones cause cellular changes by binding to receptors on target cells. The number of receptors on a target cell can increase or decrease in response to hormone activity. Hormones can affect cells directly through intracellular hormone receptors or indirectly through plasma membrane hormone receptors.

Detailed explanation-4: -A target organ is an organ in the body that is most affected by a specific chemical, drug, bacteria, or other substance. For instance, the bacteria that causes tuberculosis targets the lungs.
