B
when there isn’t enough calcium in your bloodstream
C

Explanation: 

Detailed explanation-1: -The hormones produced by the adrenal medulla are called catecholamines. They act as hormones and as neurotransmitters (chemical messengers in the nervous system). They manage the body’s response to stress. The 2 more important catecholamines are epinephrine and norepinephrine.

Detailed explanation-2: -The production of adrenaline occurs in the adrenal glands, which sit above the kidneys. Adrenaline is responsible for the fight-or-flight reaction to a threat, and it triggers specific processes in the body. For example, it might make the body send extra oxygen to the lungs to aid a person to run away.

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: -The adrenal medulla, the inner part of an adrenal gland, controls hormones that initiate the flight or fight response. The main hormones secreted by the adrenal medulla include epinephrine (adrenaline) and norepinephrine (noradrenaline), which have similar functions.
