Anatomy

1. The innate immune system provides a non-specific first line of defense. What are some physical barriers that contribute to the innate immune system?

Correct answer: C

Rationale: The correct answer is C: "Skin and mucous membranes." The innate immune system consists of physical barriers, such as the skin and mucous membranes, that act as the first line of defense against pathogens. These barriers prevent pathogens from entering the body and play a crucial role in protecting against infections. Antibodies (option A) are part of the adaptive immune response, not the innate immune system. Phagocytes (option B) are cells that engulf and destroy pathogens, which are part of the innate immune system. Memory B cells (option D) are specific to the adaptive immune response and are not considered part of the innate immunity that provides the initial, non-specific defense.

2. Define the term "velocity" in relation to motion.

Correct answer:

Rationale: Velocity is the rate of change of position concerning direction, unlike speed which only refers to distance traveled per unit time.

3. What is the breakdown product of ATP (adenosine triphosphate) that provides energy for muscle contraction?

Correct answer: C

Rationale: The correct answer is C: ADP (adenosine diphosphate). During muscle contraction, ATP is broken down into ADP and inorganic phosphate, releasing energy that fuels the muscle contraction process. This energy release allows the muscle fibers to contract and perform work. Glucose is a source of energy that is broken down through cellular respiration to produce ATP but is not the direct breakdown product of ATP itself. Creatine phosphate is another energy storage molecule in muscles but is not the breakdown product of ATP. Lactic acid is produced during anaerobic respiration when there is a lack of oxygen, and it is not the primary energy source for muscle contraction. Therefore, ADP is the correct breakdown product of ATP that provides energy for muscle contraction.

4. What is the term for a group of organisms that can interbreed and produce fertile offspring?

Correct answer: D

Rationale: Rationale: A species is defined as a group of organisms that can interbreed and produce fertile offspring. This ability to interbreed and produce fertile offspring is a key characteristic that distinguishes one species from another. In contrast, a genus (option A) is a taxonomic rank that includes one or more species that are closely related, while a phylum (option B) and a kingdom (option C) are higher taxonomic ranks that encompass multiple species.

5. Which vitamin is essential for proper absorption of calcium and plays a role in lung function?

Correct answer: C

Rationale: The correct answer is C, Vitamin D. Vitamin D is essential for the proper absorption of calcium in the intestines, which is crucial for maintaining strong bones and teeth. Additionally, Vitamin D plays a role in lung function by supporting respiratory health and reducing inflammation in the lungs. Vitamin A is important for vision and immune function, Vitamin B12 is necessary for red blood cell formation and neurological function, and Vitamin E is an antioxidant that helps protect cells from damage.

6. Which of the following is the MOST common symptom of angina pectoris, a condition related to insufficient blood flow to the heart?

Correct answer: B

Rationale: The correct answer is B: Chest pain or discomfort. Angina pectoris is characterized by chest pain or discomfort that occurs when the heart muscle does not receive enough oxygen-rich blood. This pain is often described as a squeezing, pressure, heaviness, or tightness in the chest. While other symptoms like fever, chills, shortness of breath, numbness, or tingling in the extremities can occur in various conditions, chest pain is the hallmark symptom of angina pectoris. It is important to recognize this symptom as it may indicate an underlying heart issue and prompt medical attention is crucial.
