Blood flows from the right ventricle of the heart into the lungs through the pulmonary arteries that carry deoxygenated blood. From the lungs, oxygenated blood flows through the pulmonary veins to the left atrium of the heart.
Pulmonary circulation involves movement of the blood without oxygen from the right side of the heart into the pulmonary artery of the lungs. In the lungs, blood intakes air. Now with oxygen, blood leaves the lungs and enters the pulmonary veins to return to the left side of the heart.
Yes, blood needs to go into the lungs via the pulmonary artery so gas exchange can occur. This turns the oxygen poor blood in the pulmonary artery into oxygen rich blood which is carried back to the heart via the pulmonary vein.
No, then the pathway would be wiped out and you would not be able to breathe.
The heart muscles pump blood continuously around our body, and we cannot control the movements of them like we can control the muscles in our arms and legs.
The heart is made up of four chambers: the left and right atria and ventricles. The right side always handles deoxygenated blood, and vice versa. In order that the two do not mix, there is a thick muscular wall between them. One can claim that the cycle begins at any point, but for our purposes, it shall begin with vena cavae (these are the main veins carrying blood from the body to the heart) bringing deoxygenated blood into the right atrium. It is then pumped through a valve through to the right ventricle, and it then goes into the pulmonary artery, which carries blood to the lungs. It gives the lungs carbon dioxide to breathe out and in return takes oxygen. It then goes to the left atrium, and it is pumped through a valve to the left ventricle, at which point it goes to the aorta, which is the main artery to the body. It supplies the cells with oxygen, but it soon runs out, at which point it goes back to the vena cavae, and we have completed a cycle.
Yes; pulmonary circulation is the movement of blood between the heart and lungs.
It involves the flow of blood from the right ventricle into the plumonary artery then into the lungs and back to the heart via the plumonary vein.

The oxygen is passing from through the walls of the capillaries and the organs' walls. There are specially designed proteins which are allowed from the cell, to pass through the cell's wall (membrane).

oxigen is the gas that enters the blood through the lungs
The alveoli and capillaries in the lungs pass oxygen to the blood. Both have very thin walls, which allow the oxygen to pass from the alveoli to the blood. The capillaries then connect to larger blood vessels, called veins, which bring the oxygenated blood from the lungs to the heart.
Your blood must pass through your lungs, before it goes to the rest of the body.

The blood goes through the lungs because the blood has to get purified and then go to all parts of the body.
The blood vessels that carry the blood from the heart to the lungs are the pulmonary arteries. Blood returns from the body and is pumped by the right ventricle to the lungs, through the pulmonary arteries. The blood returns to the left side of the heart through the pulmonary veins.
