These are original practice items written to the TEAS 7 blueprint (4 options, no penalty for wrong answers), not actual exam questions. Try each one before you open the answer.

What this topic covers

Science - Human Anatomy and Physiology sits inside the Science section of the TEAS 7. Our bank holds 33 verified items tagged to it, and the 4 below are a fixed sample so the page stays the same every time you open it. Each one shows the reasoning, not just the letter.

The topic tag comes from our own items rather than from a published syllabus, so treat it as a map of what we cover. For the official section breakdown see the TEAS 7 page.

Science - Human Anatomy and Physiology sample questions

Question 1

Which part of the nephron is primarily responsible for reabsorbing water under the influence of antidiuretic hormone (ADH)?

  1. A Distal convoluted tubule
  2. B Loop of Henle
  3. C Proximal convoluted tubule
  4. D Collecting duct
Show the answer and explanation

Correct answer: D

ADH increases the permeability of the collecting duct to water, allowing more water to be reabsorbed into the bloodstream. This is the main site of ADH‑regulated water reabsorption.

Why the other options are wrong:
A: The distal convoluted tubule reabsorbs ions and is involved in calcium and sodium regulation, but its water permeability is not significantly altered by ADH.
B: The loop of Henle creates a concentration gradient in the medulla but does not have ADH‑regulated water channels.
C: The proximal convoluted tubule reabsorbs most solutes and water constitutively, but it is not regulated by ADH.

Question 2

A nurse measures a patient's heart rate as 72 beats per minute and stroke volume as 70 mL per beat. What is the cardiac output in L/min?

  1. A 50.4 L/min
  2. B 5.04 L/min
  3. C 0.504 L/min
  4. D 4.0 L/min
Show the answer and explanation

Correct answer: B

Cardiac output = heart rate x stroke volume = 72 beats/min x 70 mL/beat = 5040 mL/min. Divide by 1000 mL/L to obtain 5.04 L/min.

50.4 L/min is ten times the correct result; it corresponds to dividing 5040 by 100 instead of 1000.
0.504 L/min is one tenth of the correct result; it corresponds to dividing by 10000.
4.0 L/min does not equal the product of the given heart rate and stroke volume after conversion.

Question 3

Which organ is responsible for filtering blood and producing urine?

  1. A Heart
  2. B Kidney
  3. C Liver
  4. D Pancreas
Show the answer and explanation

Correct answer: B

The kidneys filter waste from the blood to produce urine as part of the excretory system.

Why the other options are wrong:
A: The heart pumps blood but does not filter it.
C: The liver filters blood but does not produce urine; it produces bile and detoxifies substances.
D: The pancreas produces digestive enzymes and hormones like insulin, not urine.

Question 4

Which part of the brain is primarily responsible for coordinating voluntary movements and balance?

  1. A Cerebellum
  2. B Hypothalamus
  3. C Cerebrum
  4. D Medulla oblongata
Show the answer and explanation

Correct answer: A

The cerebellum processes sensory input to fine‑tune motor activity and maintain posture and balance.

Why the other options are wrong:
B: The hypothalamus regulates homeostasis, including body temperature, hunger, and thirst.
C: The cerebrum is responsible for higher functions like thought, memory, and voluntary movement initiation, not coordination and balance.
D: The medulla oblongata controls autonomic functions such as breathing and heart rate.
