Describe the function of both the pulmonary arteries and pulmonary veins. are these vessels components of pulmonary criculation or systemic circulation?

The respiratory and circulatory systems have always worked as a team to maintain the human body alive. In fact, life would not be possible if the two of them did not work in unison. As such, when the heart pumps blood from the right ventricle, it pushes this de-oxygenated blood towards the lungs for oxygenation and then the vessels that pass through the lungs return the newly oxygenated blood to the left atria, and then left ventricle, to be pumped into the system. In order to achieve this, the circulatory system counts with a pulmonary circulatory system and a systemic circulation. The first is formed by the pulmonary veins and arterties, while the second is formed by the aorta.

So given this explanation, the answers to the questions would be:

1. The vessels of the pulmonary circulation are the pulmonary arteries, whose role is to lead de-oxygenated blood from the right ventricle towards the two lungs for gas exchange, and the two pulmonary veins, who return from the lungs with the newly oxygenated blood to enter the left atria, from which blood passes to the left ventricle. From the ventricle blood is then pumped into the circulatory system.

2. Both the pulmonary arteries and pulmonary veins are part of the pulmonary circulation, while the aorta and vena cavas are the main vessels responsible for systemic circulation starting from the heart.
