Cortisol and Norepinephrine
The adrenal glands are chiefly responsible for the stress response in the body; however, the hypothalamus plays a role because it causes the pituitary gland to secrete hormones that travel to the adrenal glands initiating the stress response within the body. The adrenal gland is also known as emergency gland and releases more adrenaline under stress.
Epinephrine (also known as adrenaline) and norepinephrine are the two major neurotransmitters involved in the fight or flight response. The main hormone involved in the stress response is cortisol.
The two organs that secrete hormones are the pancreas and the adrenal glands. The pancreas produces hormones like insulin and glucagon, which regulate blood sugar levels. The adrenal glands secrete hormones such as cortisol and adrenaline, which are involved in stress response and metabolism. Together, these organs play crucial roles in maintaining homeostasis in the body.
The one most commonly thought of is cortisol, which is released by the adrenal glands in response to sustained high levels of stress. However, epinephrine and norepinephrine (old names are adrenaline and noradrenaline) are also stress hormones.
Stress and anxiety are often used interchangeably but there are differences between the two. Stress is a response to an event that causes physiological stress in the body, while anxiety is a response to an event that causes psychological stress.
The adrenal gland secretes glucocorticoids. There are two adrenal glands in the human body that sit on top of each kidney.
There are two adrenal glands, one on top of each kidney, and they both have regions that release different hormones. The adrenal cortex, which is the bigger region, releases three different hormones: mineralocorticoids (affect mineral homeostasis), glucocorticoids (affect glucose homeostasis), and androgens (male sex hormones. The other region, the adrenal medulla, produces epinephrine and norepinephrine, which set the fight or flight response into motion and help the body resist stress.
The pituitary gland produces growth hormone, which regulates growth and metabolism, and also produces adrenocorticotropic hormone (ACTH), which stimulates the adrenal glands to release cortisol in response to stress.

Two hormones that affect heart rate are epinephrine and norepinephrine. Both are actively involved with the body's stress response system. These hormones cause the body to increase heart rate so that oxygenated blood can reach muscles faster to promote more muscle strength and endurance.
The adrenal glands are associated with the production of epinephrine and norepinephrine, which are both involved in the body's "fight or flight" response to stress. These hormones help prepare the body for intense physical activity by increasing heart rate, dilating airways, and mobilizing energy stores.
