After a good meal, Jane is relaxing comfortably as her food digests, suggesting her ______ nervous system is in control. When sh
Naya [18.7K]

Answer:

After a good meal, Jane is relaxing comfortably as her food digests, suggesting her <u>parasympathetic</u> nervous system is in control. When she is frightened by a loud noise, Jane's digestion is inhibited and her heartbeat accelerates, suggesting her<u> sympathetic </u>nervous system is in control.

Explanation:

Parasympathetic nervous system and the sympathetic nervous system are two of the 3 domains of the autonomic nervous system.

During the resting and the relaxing stage,<u> parasympathetic system</u> (also called as rest or digest system) is activated which is associated with the conservation of the energy by :

1) Slowing the heart rate

2) Increasing the intestinal activity ( the reason why  Jane is relaxing comfortably as her food digests )

3) Relaxation of the sphincter muscles of the GIT.

While during the fight , flight or fright stage , the <u>sympathetic nervous system</u> is activated which is associated with the body alertness by :

1) Increasing the heart rate

2) Inhibition of secretion of GIT enzymes ( the reason why digestion of JANE is inhibited )

3) Relaxation of the walls and the contraction of the sphincters of the GIT smooth muscle.

Steroids artificially increase the amount of estrogen in the body true or false
BigorU [14]

Hello Tam121!

The correct answer to your question is false, because estrogen is any group of steroid hormones that promote the development and maintenance of female characteristics of the body. Unlike estrogen, steroids force your body to create testosterone, which has two main effects on your body: Anabolic effects (promote muscle building), and androgenic effects (responsible for male traits, such as facial hair and a deeper voice).

Hope this will help you out!
