BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Your adrenal glands make the hormone adrenaline and send it into your bloodstream. Adrenaline, a hormone your adrenal glands produce, has a purpose. It helps you face dangerous situations by causing temporary changes in your body. Your heartbeats and breathing get faster as part of the “fight or flight” response.

Detailed explanation-2: -Adrenaline triggers the body’s fight-or-flight response. This reaction causes air passages to dilate to provide the muscles with the oxygen they need to either fight danger or flee. Adrenaline also triggers the blood vessels to contract to re-direct blood toward major muscle groups, including the heart and lungs.

Detailed explanation-3: -Adrenaline is produced in the medulla in the adrenal glands as well as some of the central nervous system’s neurons. 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.

Detailed explanation-4: -Adrenaline released from the adrenal gland prepares our body for action in an emergency situation. Hence, it is called an emergency hormone, i.e., the hormone of fight or flight.

Detailed explanation-5: -Adrenaline is released into the blood during an emergency. This secretion starts responding to specific target organ activities, such as those of the heart, lungs, blood pressure, metabolism, and other organs. This hormone causes the heart to beat quickly, allowing a more oxygen intake.
