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. The axilla contains lymph nodes, blood vessels, and nerves that supply the upper limb. The other choices are incorrect: A tympanum refers to the eardrum, B rectum is part of the digestive system, and D temporal pertains to the side of the head.

Correct Answer: C

Rationale: The correct answer is C: Organ. An organ is a group of tissues that work together to perform specific functions. The heart is made up of different types of tissues (muscle, nerve, connective) that work together to pump blood throughout the body. It is more complex than a single cell (A), a group of cells (tissue - B), or a system of organs working together (body system - D). The heart's structure and function clearly demonstrate its classification as an organ.

Correct Answer: B

Rationale: The correct answer is B: Kidney dialysis. Dialysis is an artificial method used to remove waste products and excess fluids from the body when the kidneys are no longer able to perform this function adequately. It involves the use of a machine to filter blood and remove waste products. Choice A, chronic renal failure, is a condition where the kidneys fail to function properly but it is not a method of removing waste. Choice C, urine retention, is the opposite of waste removal as it refers to the inability to fully empty the bladder. Choice D, nephritis, is a condition involving inflammation of the kidneys but it does not involve the artificial removal of waste products from the body.

Correct Answer: A

Rationale: The correct answer is A: Open wound. An open wound refers to a break in the skin, exposing underlying tissues to the external environment. This is different from a closed wound (B) where the skin is intact. A contusion (C) is a bruise without a break in the skin, while a bruise (D) is a type of closed wound characterized by discoloration due to blood pooling under the skin. Therefore, in this scenario, the presence of skin not intact indicates an open wound, making choice A the correct option.

Correct Answer: A

Rationale: The correct answer is A: Enables speech. The larynx houses the vocal cords, which vibrate to produce sound during speech. The other choices are incorrect because B is the function of the epiglottis, which blocks food from entering the trachea, C is the function of the pharynx, which allows for the passage of air and food, and D is the function of the trachea, which transfers air to the lungs.
