Which of the following is NOT one of the major types of bones in the human body?
- A. Dense bone
- B. Long bone
- C. Short bone
- D. Irregular bone
Correct Answer: A
Rationale: The correct answer is A: 'Dense bone'. Dense bone is not a classification of bone types in the human body. The major types of bones include long, short, flat, and irregular bones. Long bones, like the femur, are characterized by being longer than they are wide. Short bones, such as those in the wrist (carpals) and ankle (tarsals), are generally cube-shaped. Flat bones, like the skull or scapula, are thin and provide protection. Irregular bones, such as the vertebrae, have complex shapes that do not fit into the other categories.

A dietitian wants to convince a patient to lose weight. Which statement below best communicates a scientific argument that justifies the need for weight loss?
- A. Losing weight can lower blood pressure, increase energy levels, and promote overall health.
- B. Society tends to treat overweight people unfairly.
- C. Members of the opposite sex are more interested in people who maintain a healthy weight.
- D. Losing weight is easy to do.
Correct Answer: A
Rationale: Choice A is the correct answer as it provides a scientific argument supported by evidence. Losing weight has been shown to lower blood pressure, increase energy levels, and promote overall health. These are concrete health benefits that can be objectively measured and monitored. Choices B and C do not offer scientific justifications for weight loss but rather focus on societal perceptions and personal relationships. Choice D is incorrect as losing weight is not always easy and may require significant effort and lifestyle changes.
Which of the following organs functions as both an endocrine and exocrine gland?
- A. The kidney
- B. The spleen
- C. The pancreas
- D. The stomach
Correct Answer: C
Rationale: The pancreas is the correct answer as it functions as both an endocrine and exocrine gland. The endocrine function involves secreting insulin and glucagon into the bloodstream to regulate blood sugar levels, while the exocrine function involves releasing digestive enzymes into the small intestine to aid in digestion. The kidney (Choice A) primarily functions in the excretory system by filtering blood and producing urine. The spleen (Choice B) is involved in the immune system and blood storage but does not have endocrine or exocrine functions. The stomach (Choice D) is mainly an organ of the digestive system, secreting gastric juices to aid in digestion, but it does not have a dual endocrine and exocrine function like the pancreas.
What is the name of a condition where the heart rate is 118 beats per minute (bpm)?
- A. Tachycardia
- B. Apnea
- C. Bradycardia
- D. Tachypnea
Correct Answer: A
Rationale: The correct answer is A: Tachycardia. Tachycardia is a condition characterized by a heart rate that exceeds the normal resting rate, typically above 100 bpm. In this case, a heart rate of 118 bpm falls within the range of tachycardia. Apnea (choice B) refers to the temporary cessation of breathing, not related to heart rate. Bradycardia (choice C) is a condition of an abnormally slow heart rate, opposite of the given heart rate. Tachypnea (choice D) is an abnormally rapid breathing rate, not related to heart rate.
Which of the following layers of the skin does not contain blood vessels?
- A. Hypodermis
- B. Dermis
- C. Epidermis
- D. Hyperdermis
Correct Answer: C
Rationale: The epidermis is the outermost layer of the skin and is avascular, meaning it does not contain blood vessels. It receives nutrients through diffusion from the underlying dermis. The hypodermis is the subcutaneous tissue beneath the dermis and contains blood vessels. The dermis is the layer of skin between the epidermis and hypodermis, which contains blood vessels, nerves, hair follicles, and sweat glands. 'Hyperdermis' is not a correct anatomical term and is not a layer of the skin, making it an incorrect choice for this question.
The adrenal glands are part of which system?
- A. Immune system
- B. Endocrine system
- C. Lymphatic system
- D. Respiratory system
Correct Answer: B
Rationale: The correct answer is B: Endocrine system. The adrenal glands are part of the endocrine system, not the immune, lymphatic, or respiratory system. The endocrine system is responsible for producing and regulating hormones that control various bodily functions. The adrenal glands specifically produce hormones like cortisol and adrenaline, which are critical for the body's response to stress and metabolic processes. The immune system is responsible for defending the body against infections and diseases, the lymphatic system is involved in immunity and fluid balance, and the respiratory system is responsible for gas exchange in the body. Therefore, choices A, C, and D are incorrect in the context of the adrenal glands.
