1. What is the function of the pituitary gland?

• A. Produces hormones that regulate growth and metabolism
• B. Filters blood and removes waste products
• C. Stores and releases bile
• D. Produces red blood cells

Correct answer: A

Rationale: The pituitary gland is often referred to as the "master gland" because it controls the activity of many other endocrine glands in the body. It is located at the base of the brain and produces a variety of hormones that regulate various bodily functions, including growth, metabolism, reproduction, and blood pressure.

2. Which preposition best completes the sentence: "She borrowed money _____ her friend."

• A. of
• B. from
• C. on
• D. for

Correct answer: B

Rationale: "From" indicates the source of the borrowed money.

3. What is the role of the appendix, a small pouch attached to the large intestine?

• A. To store waste products
• B. To produce immune cells
• C. To secrete digestive enzymes
• D. To regulate blood sugar levels

Correct answer: B

Rationale: While the exact function of the appendix is still debated, it likely houses lymphoid tissue, contributing to the immune system.

4. Eliminate the function NOT attributed to the lymphatic system.

• A. Fluid drainage from tissues
• B. Immune response via white blood cell production
• C. Nutrient transport throughout the body
• D. Waste removal through lymph nodes

Correct answer: C

Rationale: Rationale: A) Fluid drainage from tissues: This function is attributed to the lymphatic system. Lymphatic vessels collect excess fluid from tissues and return it to the bloodstream. B) Immune response via white blood cell production: The lymphatic system plays a crucial role in the body's immune response by producing and transporting white blood cells, such as lymphocytes, which help fight infections. C) Nutrient transport throughout the body: Nutrient transport is primarily carried out by the circulatory system (blood vessels), not the lymphatic system. The circulatory system transports nutrients, oxygen, and hormones to cells and removes waste products. D) Waste removal through lymph nodes: The lymphatic system helps remove waste and toxins from the body by filtering lymph through lymph nodes, where harmful substances are trapped and destroyed by immune cells. Therefore, the function NOT attributed to the lymphatic system is C) Nutrient transport throughout the body.

5. Which of the following terms refers to a muscle that lengthens while another muscle contracts to produce movement?

• A. Synergist
• B. Agonist
• C. Antagonist
• D. Flexor

Correct answer: C

Rationale: The correct answer is C: Antagonist. In muscle physiology, an antagonist refers to a muscle that lengthens while another muscle contracts to produce movement. This relationship allows for smooth and coordinated movement by controlling the action of the agonist muscle. For example, when you bend your arm, the biceps muscle (agonist) contracts to flex the arm while the triceps muscle (antagonist) lengthens to allow for this movement. Synergists assist the agonist muscle in performing a movement, while flexors are a type of muscle that decreases the angle between bones at a joint. Therefore, the antagonist best fits the description of a muscle that lengthens while another muscle contracts.

• C. She asked me, if I wanted, to go to the movies with her.
• D. She asked me if I wanted to go to the movies with her.

Correct answer: D

Rationale: Option D uses a question mark within the quoted material as it is a direct question.
