The right ventricle
In the human heart, the pulmonary trunk (pulmonary artery or main pulmonary artery) begins at the base of the right ventricle. It is short and wide - approximately 5 cm (2 inches) in length and 3 cm (1.2 inches) in diameter. It then branches into two pulmonary arteries (left and right), which deliver deoxygenated blood to the corresponding lung.

fossa ovalis is the wrong answer sorry for all who may have seen this here as the correct answer the correct answer is the coronary arteries
Not necessarily.
There are too many to count. There are also variations from person to person. The biggest arteries branch into smaller arteries and those branch into smaller and smaller arteries down to the arterioles, which are very small and there are many of them. Some people say there are millions of arteries in the human body. One source says there are so many arteries in the body that if you laid them end to end, they would be about 60,000 miles long.
because the lungs are deflated and not yet a source of oxygen.
Since its an airborne disease, the source is the droplet nucleid expelled when an infectious person (With pulmonary or laryngeal TB) sneezes, coughs, or sings.

There are two circulations: pulmonary which goes from heart to lung and back to the heart, and the systemic which supplies the rest of the body.Blood from the body travels through the veins to the vena cava and the right atrium of the heart. It is pumped by the right ventricle through the pulmonary arteries to the lungs. From the lungs, the blood flows back to the heart through the pulmonary veins, enters the left atrium, and is pumped by the left ventricle out through the aorta, and through the arteries to the body.
