While captain montagne is flying the airplane full of passengers from new york to houston, she engages the autopilot so that the plane will fly itself automatically for a while. which part of your nervous system is similar to the autopilot of the airplane? somatic nervous system peripheral nervous system autonomic nervous system central nervous system?

The autonomic nervous system is comparable to the autopilot in an airplane. This is because the autonomic nervous system does not need conscious input for it to work and functions autonomically. The autonomic nervous system is comprised of the symphatetic nervous system, parasymphatetic nervous system, and the enteric nervous system. The symphatetic nervous system regulates the “fight or flight” response by doing actions such as pupilary dilatation, sweating, etc. The parasyphatetic nervous system regulates the “rest and digest” response by doing actions such as pupilary constriction, defecation, etc. The enteric nervous system is an autonomic nervous system solely for the gastrointestinal tract. 

the corpus luteum secretes estrogens and progesterone. the latter hormone causes changes in the uterus that make it more suitable for implantation of the fertilized ovum and the nourishment of the embryo. if the egg is not fertilized, the corpus luteum becomes inactive after 10–14 days, and menstruation occurs.

i hope this : )
