Specialty Certified Medical Assistant Anatomy, Physiology, and Medical Terminology 2 — Questions and Answers
Question 1: What is the function of the lymphatic system?
- Producing red blood cells
- Returning excess interstitial fluid to circulation, absorbing dietary fats, and supporting immune function (Correct answer)
- Filtering blood and producing urine
- Producing hormones that regulate metabolism
Correct answer: Returning excess interstitial fluid to circulation, absorbing dietary fats, and supporting immune function
The lymphatic system drains excess tissue fluid back to the bloodstream, transports dietary lipids, and is central to immune defense through lymphocyte production.
Question 2: Which suffix means 'surgical removal of' in medical terminology?
- -itis
- -ectomy (Correct answer)
- -plasty
- -oscopy

The suffix '-ectomy' means surgical removal, as in appendectomy (removal of the appendix) or cholecystectomy (removal of the gallbladder).
Question 3: Which bone is commonly known as the kneecap?
- Fibula
- Tibia
- Patella (Correct answer)
- Femur
Correct answer: Patella
The patella is a sesamoid bone embedded in the quadriceps tendon that protects the knee joint and improves the mechanical advantage of the quadriceps muscle.
Question 4: What is the normal adult respiratory rate at rest?
- 6-10 breaths per minute
- 12-20 breaths per minute (Correct answer)
- 22-28 breaths per minute
- 30-36 breaths per minute
Correct answer: 12-20 breaths per minute
The normal adult resting respiratory rate is 12-20 breaths per minute; values outside this range may indicate respiratory compromise.
Question 5: What does the medical term 'hematuria' mean?
- Blood in the urine (Correct answer)
- Excess protein in the urine
