• C. Less than 129 mg/dL
• D. Less than 170 mg/dL

Correct answer: B

Rationale: An LDL cholesterol level of less than 110 mg/dL is considered acceptable and healthy for children and adolescents. This level helps reduce the risk of cardiovascular diseases. Choices A, C, and D are incorrect because an LDL cholesterol level below 110 mg/dL is the recommended target for children and adolescents to maintain good heart health.

2. Churns chyme and has an environment of pH2; holds 4-6 cups of food:

• A. stomach
• B. pancreas

4. Why is atherosclerosis dangerous to arterial function?

• A. It diminishes central circulation
• B. It causes decreased blood pressure on artery walls
• C. It narrows the arterial lumen so a clot can easily block it
• D. It increases arterial elasticity

Correct answer: C

Rationale: Atherosclerosis is dangerous to arterial function because it narrows the arterial lumen, increasing the risk of a clot completely blocking the blood flow. This can lead to severe cardiovascular events such as heart attacks or strokes. Choice A is incorrect since atherosclerosis does not primarily diminish central circulation, but rather, it impedes local blood flow where the plaque is present. Choice B is also incorrect as atherosclerosis increases the pressure on artery walls due to the narrowed space for blood flow, not decrease it. Lastly, choice D is incorrect as atherosclerosis causes the arteries to lose their elasticity, not increase it.

5. What is the primary function of antioxidants in the diet?

• A. Provide energy
• B. Support muscle growth
• C. Neutralize free radicals

Rationale: The primary function of antioxidants in the diet is to neutralize free radicals. Free radicals can cause cellular damage, leading to various chronic diseases. Antioxidants help combat this oxidative stress by neutralizing free radicals. Choices A, B, and D are incorrect because antioxidants do not provide energy, support muscle growth, or increase blood sugar; their main role is in combating oxidative stress.
