The Endocrine System Consists of glands that secrete chemicals into the bloodstream that help control bodily functioning. Hormones- the chemical substances that are released by the endocrine glands. Different from neurotransmitters because NTs travel short distances with lightening speed whereas hormones travel to distant cells at a much slower speed
Endocrine System (cont.) Stomach and Intestines help control digestion Kidney hormones play a part in regulating blood pressure Pancreatic hormone (insulin) is essential for cells to use sugar from the blood These hormones are pulsatile and are released several times a day in bursts or pulses.
Endocrine System (cont.) Controlled by the hypothalamus which is connected to the pituitary gland The pituitary gland releases a variety or hormones that fan out around the body, stimulating action in the other endocrine glands AKA- Master gland
