1. From an anterior view, which of the following vessels carries blood away from the heart?

Correct answer: D

Rationale: The correct answer is D, 'All of the above.' When viewed from an anterior perspective, the left common carotid artery, pulmonary trunk, and subclavian arteries all carry blood away from the heart. The left common carotid artery supplies oxygenated blood to the head and neck, the pulmonary trunk carries deoxygenated blood to the lungs for oxygenation, and the subclavian arteries transport blood to the upper extremities. Therefore, all the vessels listed in the choices are correct as they function to carry blood away from the heart when viewed anteriorly.

2. Which of the following structures in the body is responsible for protecting the lungs and heart?

Correct answer: A

Rationale: The rib cage is the correct answer. It plays a crucial role in protecting vital organs like the lungs and heart. The rib cage forms a protective barrier around these organs, shielding them from external trauma or injuries. It acts as a sturdy cage, offering structural support and safeguarding the delicate tissues and structures of the lungs and heart. The pelvis, femur, and vertebral column do not directly protect the lungs and heart; instead, they have other important functions in the body, such as supporting the body's weight, enabling movement, and protecting the spinal cord.

3. The liver plays a vital role in digestion. What is one of the main functions of the liver in the digestive system?

Correct answer: C

Rationale: The correct answer is C: Storage and processing of nutrients. The liver plays a crucial role in processing nutrients absorbed from the small intestine, storing glycogen, vitamins, and minerals, and regulating blood sugar levels by releasing or storing glucose as needed. Choices A, B, and D are incorrect because the physical breakdown of food primarily occurs in the mouth and stomach, the production of digestive enzymes is mainly carried out by the pancreas and small intestine, and the elimination of waste products is primarily managed by the large intestine and kidneys, not the liver.

4. What is hemoglobin?

Correct answer: B

Rationale: Hemoglobin is a protein found in red blood cells that plays a crucial role in transporting oxygen from the lungs to the tissues and organs in the body. It is composed of four protein subunits, each containing a heme group that binds to oxygen molecules. Choice A is incorrect as hemoglobin is not an enzyme, but rather a protein. Choice C is incorrect as hemoglobin is not a lipid, but a protein. Choice D is incorrect as hemoglobin is not an acid, but a protein.

5. What are the four types of cells in the gastric glands of the stomach mucosa?

Correct answer: A

Rationale: The correct answer is A: Endocrine, parietal, chief, mucous cells. In the gastric glands of the stomach mucosa, the four types of cells are endocrine (producing hormones), parietal (secreting acid and intrinsic factor), chief (responsible for producing digestive enzymes), and mucous cells (providing protection to the stomach lining). These cells play essential roles in the digestive processes and maintaining the health of the stomach mucosa. Choices B, C, and D are incorrect because they do not accurately represent the types of cells found in the gastric glands of the stomach mucosa. Parietal cells secrete acid and intrinsic factor, chief cells produce digestive enzymes, and mucous cells provide protection, making these the correct choices in the context of gastric gland cellular composition.
