Adrenaline causes a noticeable increase in strength and performance, as well as heightened awareness, in stressful times. The body's ability to feel pain also decreases as a result of adrenaline, which is why you can continue running from or fighting danger even when injured. Adrenaline also triggers the blood vessels to contract to re-direct blood toward major muscle groups, including the heart and lungs. This reaction causes air passages to dilate to provide the muscles with the oxygen they need to either fight danger or flee. What is the Function of Adrenaline?Īdrenaline triggers the body's fight-or-flight response. Within a couple of minutes during a stressful situation, adrenaline is quickly released into the blood, sending impulses to organs to create a specific response. The hormones from the hypothalamus and pituitary can also act on other glands to stimulate the release of different types of hormones and bring about effects.Adrenaline is produced in the medulla in the adrenal glands as well as some of the central nervous system's neurons. The hypothalamus detects changes in hormone levels and will release hormones which control the pituitary gland or other organs. It secretes several hormones into the blood in response to the body's condition, such as blood water levels.

The pituitary gland in the brain is known as a 'master gland'.

Increases conversion of glucose into glycogen for storage Increases breathing rate, heart rate, flow of blood to muscles, conversion of glycogen to glucose Several targets including organs in the respiratory and circulatory systems Increases reabsorption of water by the collecting ducts HormoneĬontrolling the water content of the blood Important hormones released into the bloodstream include ADH (anti-diuretic hormone), adrenaline and insulin. The glands in the body produce a range of different chemical hormones that travel in the bloodstream and affect a number of different organs in the body. There are important differences between nervous and hormonal control. Contraceptive pills contain hormones to reduce the chances of becoming pregnant
