2. The carotid arteries.
3. The coronary arteries.
4. The saphenous veins.

Question 2

Answer to Question 1

Correct Answer: 3
Rationale 1: The jugular vein brings deoxygenated blood from the head to the heart.
Rationale 2: The carotid arteries supply blood to the head and neck.
Rationale 3: The coronary arteries bring essential nutrients to the myocardium.
Rationale 4: The saphenous veins are superficial veins of the legs.
Global Rationale: The coronary arteries bring essential nutrients to the myocardium. The jugular vein brings deoxygenated blood from the head to the heart. The carotid arteries supply blood to the head and neck. The saphenous veins are superficial veins of the legs.

Answer to Question 2

Correct Answer: 2
Rationale 1: Constricting of the coronary arteries would lead to ischemia and chest pain.
Rationale 2: An increased heart rate and stronger cardiac contraction indicate that dilation is occurring.
Rationale 3: Experiencing a vasospasm of the coronary arteries would lead to ischemia and chest pain.
Rationale 4: No change in the coronary arteries would possibly lead to ischemia and chest pain.
Global Rationale: An increased heart rate and stronger cardiac contraction indicate that dilation is occurring. Constricting of the coronary arteries, vasospasm, and no change would lead to ischemia and chest pain.
