What is the Endocrine System
The endocrine system controls body functions using hormones, which are chemical messengers. Works more slowly because hormones travel through the blood to reach their targets.
Identify the role of a hormone
A hormone is a chemical messenger that controls body functions like growth, mood, and energy by traveling in the blood.
Describe how they affect target cells
Hormones attach to specific receptors on target cells, sending signals that change the cell’s activity. This can make the cell grow, produce energy, or release other chemicals.
Where is the Pituitary gland located?
The pituitary gland is located at the base of the brain, beneath the hypothalamus.
Where is the Thyroid gland located?
The thyroid gland is located in the front of the neck, below the Adam’s apple.
Where is the Ovaries gland located?
The ovaries are located in the lower abdomen, on either side of the uterus.
Where is the Testes gland located?
The testes are located in the scrotum, a sac-like structure beneath the penis.
Where is the Adrenal gland located?
The adrenal glands are located on top of each kidney.
Where is the Pancreas gland located?
The pancreas is located behind the stomach, in the upper abdomen.
