Question 1 of 5
What is the function of the liver in digestion?
Correct Answer: A
Rationale: The correct answer is A: To produce bile. The liver produces bile, which is essential for the breakdown and absorption of fats in the small intestine. B is incorrect because the storage of glucose is primarily done in the liver, not for digestion. C is incorrect as the pancreas, not the liver, secretes digestive enzymes. D is incorrect as while the liver does play a role in detoxification, its primary function in digestion is bile production.
Question 2 of 5
Which structure is part of both the male reproductive system and the urinary system?
Correct Answer: B
Rationale: The correct answer is B: Urethra. The urethra is a structure that is part of both the male reproductive system and the urinary system. In males, the urethra serves as the passage for both urine and semen. It connects the urinary bladder to the outside of the body. The other choices are incorrect because: A: Bladder is solely part of the urinary system, storing urine. C: Prostate is an accessory gland in the male reproductive system, producing fluids for semen. D: Seminal Vesicle is also part of the male reproductive system, producing seminal fluid.
Question 3 of 5
Which bone does not articulate with any other bone in the body?
Correct Answer: B
Rationale: The correct answer is B: Hyoid. The hyoid bone is unique as it does not directly articulate with any other bone in the body, making it a free-floating bone. It serves important functions in supporting the tongue and aiding in swallowing. A: Scapula articulates with the clavicle and humerus. C: Radius articulates with the ulna, humerus, and carpal bones. D: Femur articulates with the hip bone and tibia. Therefore, the hyoid bone is the only bone in the body that does not directly articulate with another bone.
Question 4 of 5
What is the primary function of the pancreas in digestion?
Correct Answer: B
Rationale: The correct answer is B: To secrete digestive enzymes. The pancreas secretes enzymes such as amylase, lipase, and proteases that aid in breaking down carbohydrates, fats, and proteins in the small intestine. This supports the digestion and absorption of nutrients. Choices A, C, and D are incorrect because the pancreas does not directly absorb nutrients, produce bile, or store glucose.
Question 5 of 5
What is the primary function of the heart in the circulatory system?
Correct Answer: B
Rationale: The correct answer is B: To pump blood throughout the body. The heart's primary function is to act as a muscular pump that circulates blood, delivering oxygen and nutrients to the body's tissues and removing waste products. It plays a crucial role in maintaining the flow of blood through the circulatory system. Explanation of other choices: A: To filter blood - This is incorrect, as the kidneys are responsible for filtering blood. C: To absorb oxygen - This is incorrect, as the lungs are responsible for absorbing oxygen. D: To remove carbon dioxide - This is incorrect, as the lungs are responsible for removing carbon dioxide during respiration.
