What is a target organ?
A target organ is an organ that is targeted by a drug or hormone. These drugs usually stimulate the organ to produce its own hormones or react positively and function in response to the drug, such as adrenaline to the heart.
What causes a pituitary gland not to release enough hormones?
You have the various releasing factors, that come from the hypothalamus. The low level of the hormones from the target organ like thyroid may stimulate thyroid stimulating hormone from the pituitary.
What organ system directs long-term changes in the activities of the other organ systems?
The endocrine system is responsible for regulating long-term changes in the activities of the other organ systems through the release of hormones. Hormones act as chemical messengers that travel through the bloodstream to target organs, where they help regulate various processes such as metabolism, growth, and reproduction.
Most hormones are inactivated or excreted by what organs?
Glands excrete hormones, which is sent to the blood which is then sent to the target organ.
What happens once a hormone reaches a target organ or cell?
Once a hormone reaches it's target organ or cell, it increases or decreases the action in the organ or cell. This occurs with the metabolism of the hormones and cells.
What is the difference between plant hormones and animal hormones?
The plant hormones different parts of the plants in a different way while the animal hormones affect the target cells in more than one organ.
What are hormones carried in to their target cell?
