Question 1

Which of the following best describes the primary function of histology in the study of anatomy and physiology?

Accepted Answer

Histology is the study of tissues at the microscopic level to understand their structure and function.

Question 2

During a blood typing lab, a student observes agglutination when anti-A serum is added to a blood sample, but not with anti-B serum. What is the blood type of the sample?

Accepted Answer

Type A

Question 3

A patient’s pulse oximetry reading is 92%. Which of the following best describes the physiological implication of this result?

Accepted Answer

The patient is experiencing mild hypoxemia and may require supplemental oxygen.

Question 4

Which instrument is most appropriate for examining the microscopic structure of tissues in a histology lab?

Accepted Answer

Microscope

Question 5

A student is asked to identify the tissue type responsible for lining the blood vessels. Which tissue should they select?

Accepted Answer

Simple squamous epithelium

Question 6

During a kidney dissection, which structure is responsible for filtering blood to form urine?

Accepted Answer

Nephron

Question 7

A spirometry test measures which of the following physiological parameters?

Accepted Answer

Lung volumes and airflow rates

Question 8

If a student observes a tissue sample with striations and multiple nuclei per cell under the microscope, which tissue type are they most likely viewing?

Accepted Answer

Skeletal muscle

Question 9

Which formula is used to calculate cardiac output ($$CO) in a $$physiology lab?

Accepted Answer

$$CO = HR 	imes SV$$

Question 10

A student is reviewing blood histology slides and identifies cells with no nucleus and a biconcave shape. What type of cell are they observing?

Accepted Answer

Erythrocyte

Question 11

During a lab on arteries and veins, which of the following best describes a key structural difference between arteries and veins?

Accepted Answer

Arteries have thicker walls and more elastic tissue than veins.

Question 12

Which of the following best explains why the left ventricle of the heart has a thicker wall than the right ventricle?

Accepted Answer

The left ventricle pumps blood to the entire body, requiring higher pressure.

Question 13

A patient’s EKG shows an abnormally long $$QRS$$ complex. What does this most likely indicate?

Accepted Answer

Delayed ventricular depolarization

Question 14

Which of the following is the correct sequence of blood flow through the heart?

Accepted Answer

Right atrium → Right ventricle → Pulmonary artery → Lungs → Left atrium → Left ventricle → Aorta

Question 15

Which equation is used to determine the vital capacity ($$VC) of $$the lungs in a spirometry lab?

Accepted Answer

$$VC = TV + IRV + ERV$$

Question 16

A histology slide shows cells with intercalated discs and branching fibers. Which tissue is being observed?

Accepted Answer

Cardiac muscle

Question 17

Which of the following best describes the function of the glomerulus in the kidney?

Accepted Answer

Filtration of blood to form filtrate

Question 18

A student is asked to calculate the total lung capacity ($$TLC) $$using the following values: $$TV = 500\,mL$$, $$IRV = 3000\,mL$$, $$ERV = 1200\,mL$$, $$RV = 1200\,mL. $$Which formula should they use and what is the result?

Accepted Answer

$$TLC = TV + IRV + ERV + RV = 500 + 3000 + 1200 + 1200 = 5900\,mL$$

Question 19

Which of the following best explains the physiological role of arteries in the circulatory system?

Accepted Answer

Arteries carry blood away from the heart under high pressure.

Question 20

In a blood histology lab, which cell type is primarily responsible for immune defense?

Accepted Answer

Leukocyte
