1. Which gland is located superior to the kidney?

• A. Pituitary
• B. Adrenal
• C. Hypothalamus
• D. Pancreas

Correct answer: B

Rationale: The adrenal gland is located superior to the kidney. Each kidney is surrounded by an adrenal gland, also known as the suprarenal gland, situated on top of the kidneys. The pituitary gland (A) is located in the brain, while the hypothalamus (C) is also in the brain, above the pituitary gland. The pancreas (D) is located in the abdomen, near the stomach and small intestine, not superior to the kidney.

2. Which of the following epithelial types is correctly matched with its major function?

• A. Simple squamous epithelium – diffusion
• B. Stratified squamous epithelium – protection
• C. Stratified squamous epithelium – diffusion
• D. Simple columnar epithelium – secretion or absorption

Correct answer: D

Rationale: The correct answer is D. Simple columnar epithelium is indeed primarily responsible for secretion and absorption due to its tall shape and presence of microvilli, which increase surface area for these functions. Simple squamous epithelium is mainly involved in diffusion, allowing for the exchange of gases or nutrients. Stratified squamous epithelium functions more for protection against mechanical stress and pathogens, as it forms a tough, protective barrier due to its many layers.

3. Which is an anterior feature of the human head?

• A. The nose
• B. The ears
• C. The occipital lobe
• D. The temporal lobe

Correct answer: A

Rationale: The nose is an anterior feature of the human head, located in the frontal part of the face. It plays a vital role in the respiratory system by allowing air to enter and exit the body. Additionally, the nose contains olfactory receptors that enable the sense of smell. The ears, occipital lobe, and temporal lobe are not anterior features of the human head. The ears are located on the sides, the occipital lobe is at the back of the head, and the temporal lobe is on the sides and base of the cerebral cortex.

4. The vena cavae drain blood from the body into the ___________.

• A. right atrium
• B. right ventricle
• C. left atrium
• D. left ventricle

Correct answer: A

Rationale: The vena cavae are large veins responsible for returning deoxygenated blood from the body to the heart. They empty into the right atrium of the heart. From the right atrium, the blood is then pumped into the right ventricle before being sent to the pulmonary circulation for oxygenation, making choice A, 'right atrium,' the correct answer. Choices B, C, and D are incorrect because the vena cavae do not empty into the ventricles of the heart; instead, they deliver blood to the atria.

5. The lateral side of the right knee would be ___________.

• A. the kneecap
• B. closest to the left knee
• C. farthest from the left knee
• D. on the underside of the knee

Correct answer: C

Rationale: The lateral side of the right knee is the side that is farthest from the left knee when looking at the knee joint from the front. The term 'lateral' refers to the side of the body that is farther away from the midline or center of the body. In this case, the lateral side of the right knee is on the outer side of the knee joint, away from the other knee. Choice A is incorrect as the kneecap is located at the front of the knee. Choice B is incorrect as it describes the medial side, not the lateral side. Choice D is incorrect as it refers to the underside, which is not related to the lateral aspect of the knee.
