Here's why:
* Target cells: Individual cells that have receptors for a specific hormone. These receptors allow the hormone to bind and initiate a cellular response.
* Target tissues: A group of cells that are all sensitive to a particular hormone due to the presence of receptors for that hormone.
Examples:
* Insulin: Targets cells in the liver, muscle, and fat tissue to regulate glucose uptake.
* Estrogen: Targets cells in the uterus, breasts, and other reproductive organs to regulate female reproductive development.
It's important to note that not all cells in the body are target cells for every hormone. Each hormone has specific target cells or tissues that it acts upon.
