Katrina is diagnosed with lactose intolerance. To avoid complications with lack of calcium in the diet, which food should be included in the diet?

Correct Answer: D

Rationale: The correct answer is D: Dark green, leafy vegetables. Dark green, leafy vegetables are a good source of calcium and can help Katrina meet her calcium needs without consuming milk and cheese products. Since Katrina is lactose intolerant, consuming milk and cheese products can lead to gastrointestinal issues due to the inability to digest lactose. Fruits and whole grains do not provide significant amounts of calcium compared to dark green, leafy vegetables. Therefore, including dark green, leafy vegetables in the diet is the best option to prevent complications from lack of calcium intake.

Correct Answer: D

Rationale: Correct Answer: D Rationale: 1. The enteric nervous system can autonomously regulate digestive functions locally without input from the central nervous system. 2. Enteric sensory and motor neurons are key components of the enteric nervous system, responsible for detecting stimuli and coordinating gut movements. 3. Enteric interneurons play a crucial role in connecting sensory and motor neurons within the enteric nervous system. 4. Choice D is false because the enteric neurons are capable of controlling digestive tract functions independently from the central nervous system.

Correct Answer: B

Rationale: The correct answer is B: mesentery proper. The mesentery proper consists of two layers of serous membranes with a thin layer of connective tissue between them, and it attaches to the small intestine. This structure provides support and allows for movement of the small intestine. A: The lesser omentum attaches the stomach to the liver, not the small intestine. C: The greater omentum is a large apron-like structure that hangs down from the stomach and covers the intestines, but it does not specifically attach to the small intestine. D: The falciform ligament attaches the liver to the diaphragm and anterior abdominal wall, not the small intestine.

Correct Answer: B

Rationale: The correct answer is B: pulp cavity; root canal. The pulp cavity is the center of the tooth filled with blood vessels and nerves, while the root canal is the cavity within the root of the tooth. This is because the pulp cavity contains the pulp tissue, which includes blood vessels and nerves, providing nourishment and sensation to the tooth. The root canal, on the other hand, is the space within the root where the pulp tissue extends down into. Choices A, C, and D are incorrect because they do not accurately describe the specific structures mentioned in the question.

Correct Answer: D

Rationale: The correct answer is D: sublingual gland. This gland primarily produces mucus, aiding in lubrication and initial digestion. The sublingual gland is located under the tongue. A: The parotid gland primarily produces serous saliva. B: Labial glands are minor salivary glands located in the lips, producing mixed saliva. C: Submandibular gland produces a mixture of serous and mucous saliva.
