ANATOMY AND PHYSIOLOGY,,
CHAPTER 1 PRACTICE TEST
QUESTIONS AND ANSWERS 2025-2026
A group of cells of the same type form a(n):
organ.
organism.
atom.
tissue.
organ system. - correct answer-tissue.
Which system complements the circulatory system and involves the spleen?
The urinary system.
The lymphatic system.
The digestive system.
The endocrine system.
The reproductive system. - correct answer-The lymphatic system.
The lymphatic system complements the circulatory system by returning blood back to the blood ve
ssels, and consists of lymph nodes, lymph vessels, and lymphoid organs such as the spleen and ton
sils.
A group of tissues working together for a specific function form a(n):
organ.
organism.
positive feedback system.
organ system.
organelle. - correct answer-organ.
, Which of the following statements regarding responsiveness, or irritability, is FALSE?
Responsiveness, or irritability, is a necessary life function.
All body cells are irritable to some extent.
Because nerve cells are slightly irritable and communicate rapidly with each other via hormones, t
he nervous system bears the major responsibility for responsiveness.
You do not need to think about responsiveness, such as involuntarily pulling your hand away from
a painful stimulus.
None of the statements is false. - correct answer-
Because nerve cells are slightly irritable and communicate rapidly with each other via hormones, th
e nervous system bears the major responsibility for responsiveness.
The ability of the body to maintain a relatively stable internal environment is referred to as:
equilibrium.
homeostasis.
metabolism.
negative feedback.
positive feedback. - correct answer-homeostasis.
This refers to maintaining a relatively stable internal environment even though the outside world is
continuously changing.
The anatomical term meaning away from the midline is
distal.
inferior.
lateral.
medial.
proximal. - correct answer-lateral.
