Anatomy

1. Which part of the respiratory system is responsible for gas exchange between the blood and inhaled air?

Correct answer: C

Rationale: The correct answer is C, 'Alveoli.' The alveoli are tiny air sacs located at the end of the bronchioles in the lungs where gas exchange occurs. Oxygen from the inhaled air diffuses through the thin walls of the alveoli and into the bloodstream, while carbon dioxide from the blood diffuses into the alveoli to be exhaled. The trachea (A) is the windpipe that carries air to and from the lungs; the larynx (B) contains the vocal cords and helps with swallowing; and the pharynx (D) is the part of the throat that connects the mouth and nasal cavity to the esophagus and trachea, but it is not directly involved in gas exchange.

2. The sentence "The audience was captivated by the speaker's compelling story" implies that the audience:

Correct answer: C

Rationale: "Captivated" suggests the audience was completely held by the speaker's story.

3. The muscular diaphragm plays a vital role in respiration. When it contracts, it:

Correct answer: A

Rationale: The diaphragm is a crucial muscle involved in respiration. When the diaphragm contracts, it flattens and moves downwards, increasing the volume in the thoracic cavity. This expansion creates a negative pressure in the lungs, causing air to rush in during inhalation. Therefore, option A, 'Increases lung volume for inhalation,' is the correct answer. The diaphragm's contraction facilitates the breathing process by creating space for the lungs to expand and take in air, making it essential for proper respiration.

4. Which of the following is an example of static friction?

Correct answer: c

Rationale: Static friction occurs when an object is at rest and prevents it from moving when a force is applied.

5. The pH scale is used to indicate the concentration of:

Correct answer: A

Rationale: The pH scale measures the concentration of hydrogen ions in a solution, indicating acidity or basicity.

6. In the process of cellular respiration, glucose is broken down to produce energy. What is the main waste product released?

Correct answer: B

Rationale: The correct answer is B: Carbon dioxide. During cellular respiration, glucose is broken down in the presence of oxygen to produce energy in the form of ATP. One of the main waste products released in this process is carbon dioxide. Carbon dioxide is a byproduct of the metabolic reactions occurring in cells and is expelled from the body through exhalation. Water is also produced during cellular respiration, but it is not the main waste product released. Oxygen is required for cellular respiration to occur, and protein is a macromolecule and not a waste product of cellular respiration.
