Question 1

Which of the following best describes the pathway of sperm from production to ejaculation in the male reproductive system?

Accepted Answer

Seminiferous tubules → epididymis → vas deferens → urethra

Question 2

Which hormone is primarily responsible for triggering ovulation during the female reproductive cycle?

Accepted Answer

Luteinizing hormone (LH)

Question 3

A patient presents with a blockage in the efferent lymphatic vessels of a lymph node. Which of the following is the most likely consequence?

Accepted Answer

Lymph will accumulate within the lymph node, causing swelling.

Question 4

Which of the following correctly traces the flow of blood through the heart, starting from the right atrium?

Accepted Answer

Right atrium → right ventricle → pulmonary artery → lungs → left atrium → left ventricle → aorta

Question 5

Which of the following is the correct formula for cardiac output?

Accepted Answer

$$CO = HR 	imes SV$$

Question 6

Which of the following best describes the difference between filtration and reabsorption in the nephron?

Accepted Answer

Filtration occurs in the glomerulus, while reabsorption occurs primarily in the proximal convoluted tubule.

Question 7

A patient is diagnosed with metabolic acidosis. Which function of the kidney is most directly involved in compensating for this condition?

Accepted Answer

Secretion of hydrogen ions into the nephron

Question 8

Which of the following cranial nerves is responsible for transmitting visual information from the eye to the brain?

Accepted Answer

Optic nerve (Cranial Nerve II)

Question 9

Which of the following best describes the role of helper T cells in the adaptive immune response?

Accepted Answer

They activate B cells and cytotoxic T cells by releasing cytokines.

Question 10

Which of the following is a key difference between innate (nonspecific) and adaptive (specific) immunity?

Accepted Answer

Adaptive immunity involves memory cells, while innate immunity does not.

Question 11

Which hormone is released by the kidneys in response to low blood oxygen levels, and what is its primary function?

Accepted Answer

Erythropoietin; stimulates red blood cell production

Question 12

Which of the following is a normal component of urine?

Accepted Answer

Urea

Question 13

Which of the following best describes the function of the lymphatic capillaries?

Accepted Answer

They absorb excess interstitial fluid and transport it as lymph.

Question 14

A patient receives an injection of antibodies after exposure to a disease. This is an example of which type of immunity?

Accepted Answer

Artificial passive immunity

Question 15

Which of the following correctly matches a heart valve with the chambers it separates?

Accepted Answer

Mitral (bicuspid) valve: left atrium and left ventricle

Question 16

Which of the following is the correct order of fluid flow through the nephron?

Accepted Answer

Glomerular capsule → proximal convoluted tubule → loop of Henle → distal convoluted tubule → collecting duct

Question 17

Which of the following best describes the function of plasma B cells?

Accepted Answer

They produce and secrete large quantities of antibodies.

Question 18

Which cranial nerve is responsible for most of the parasympathetic output to the thoracic and abdominal organs?

Accepted Answer

Vagus nerve (Cranial Nerve X)

Question 19

Which of the following best explains why females are more prone to urinary tract infections (UTIs) than males?

Accepted Answer

Females have a shorter urethra, allowing bacteria easier access to the bladder.

Question 20

Which of the following is a function of the hormone antidiuretic hormone (ADH) in the urinary system?

Accepted Answer

It increases water reabsorption in the collecting ducts of the nephron.
