Which of the following is another word for armpit?

Correct Answer: C

Rationale: The correct answer is C: Axilla. The axilla is the anatomical term for the armpit region. This area contains lymph nodes, blood vessels, and nerves. The other choices are incorrect: A: Tympanum refers to the eardrum. B: Rectum is the final section of the large intestine. D: Temporal relates to the temples on the sides of the head. In summary, the axilla specifically refers to the armpit region, making it the correct answer.

Correct Answer: C

Rationale: The correct answer is C: Organ. An organ is a structure made up of different tissues working together to perform a specific function, such as the heart pumping blood. It is not a single cell (A), a group of cells (B), or a collection of organs working together (D). The heart fits the definition of an organ, making choice C the most appropriate.

Correct Answer: B

Rationale: The correct answer is B: Kidney dialysis. Dialysis is an artificial process that helps remove waste products from the body when the kidneys are unable to do so effectively. It involves filtering the blood to remove toxins and excess fluids. Chronic renal failure (A) is a condition where the kidneys gradually lose function. Urine retention (C) is the inability to empty the bladder completely. Nephritis (D) is inflammation of the kidneys. Dialysis is the most direct and effective method for removing waste products in cases of kidney failure.

Correct Answer: A

Rationale: The correct answer is A: Open wound. An open wound refers to any break in the skin's surface, exposing underlying tissues. In contrast, a closed wound does not break the skin. A contusion is a bruise resulting from blunt force trauma, while a bruise specifically refers to discoloration of the skin due to broken blood vessels beneath the skin without breaking the skin itself. Therefore, in this scenario, the skin not being intact categorizes it as an open wound rather than a closed wound, contusion, or bruise.

Correct Answer: A

Rationale: The correct answer is A: Enables speech. The larynx, also known as the voice box, contains vocal cords that vibrate to produce sound, enabling speech. Choice B is incorrect because the epiglottis, not the larynx, blocks food from entering the trachea. Choice C is incorrect as the larynx is not involved in the passage of food. Choice D is incorrect because the larynx does not transfer air to the lungs, but rather filters and humidifies air before it reaches the lungs.
