Which of the following correctly describes the anatomical position of the human body? - CORRECT ANS-
Head is level, eyes directed anteriorly; feet flat on the floor and parallel; toes pointed anteriorly; upper
limbs at sides of the body with palms facing anteriorly.
Homeostasis is the ___1__ of the body's internal environment. The nervous system uses electrical
signals called___2____ to transmit instructions that help bring back equilibrium. The endocrine system
does the same by using glands to send out molecular messengers known as ____3___. The nervous and
endocrine system maintain homeostasis by triggering ___4___. - CORRECT ANS-1. equilibrium
2. nerve impulses
3. hormones
4. feedback systems
Which of the following components of a feedback system receives information regarding a desired
response? - CORRECT ANS-Effector
A positive feedback system does which of the following? - CORRECT ANS-Strengthens or reinforces a
change in a controlled condition
In a negative feedback system in which high blood pressure is detected and reduced to restore
homeostasis, which of the following steps represents the action of effectors? - CORRECT ANS-Heart rate
slows and blood vessels dilate, decreasing blood pressure.
Chemical Level - CORRECT ANS-Includes atoms and molecules
cellular level - CORRECT ANS-includes cells, which are composed of chemicals and molecules
