Final answer:
The provided options do not correctly list the vessels that directly carry blood to the superior vena cava, but systemic veins carry deoxygenated blood from the upper body to the superior vena cava.
Step-by-step explanation:
The two vessels that carry blood directly to the superior vena cava are not explicitly named in the options provided. However, based on the provided information, we can infer that the vessels connecting to the superior vena cava are the systemic veins that carry deoxygenated blood from the upper body. The superior vena cava itself enters the right atrium of the heart. None of the options A) Pulmonary Artery, Aorta B) Inferior Vena Cava, Pulmonary Vein C) Pulmonary Vein, Superior Vena Cava D) Aorta, Inferior Vena Cava accurately represent two vessels that directly connect to the superior vena cava, but option C mentions the superior vena cava as one of the vessels, which is redundant in this context.
The two vessels that carry blood directly to the superior vena cava are the Pulmonary Vein and the Superior Vena Cava.
