Answer
a) The main artery leaving the heart is called the Aorta.b) The large vein entering the heart is known as the Vena Cava.
Explanation
## Step 1: The solution to this problem involves recognizing the major anatomical cardiovascular structures that directly interact with the heart to assist in systemic as well as pulmonary circulation. No quantitative analysis or calculations are required for this problem, it depends solely on factual recall and understanding.## Step 2: Identify the main artery that leaves the heart. This artery is known as the "aorta",- the largest artery in the body. The aorta arises from the left ventricle of the heart, extends upwards into the thoracic cavity, then turns down into the abdominal cavity to bifurcate into the left and right common iliac arteries.## Step 3: Identify the large vein that enters the heart. This referred to as the "vena cava" and is essentially of two types: The "superior" and the "inferior" vena cava. The superior one brings deoxygenated blood from the upper part of the body back to the heart, whereas the inferior one brings deoxygenated blood from the lower part of the body back to the heart.
