does not exist.

perfectly obeys all gas laws.

Explanation:

An ideal gas is the one which obeys all the ideal gas laws. There are some assumptions of ideal gas laws which are mentioned as under:

(1) There are no interactions (attractive/repulsive) at all among the particles of a gas.

(2) Collision of ideal gas particles among each other are elastic. Elastic collision is a kind of collision in which kinetic energy is conserved i.e. loss of total kinetic energy is nil.

(3) Gas particles display rapid, constant & random  motion and the sizes of particles of a gas are extremely small as compared to their distance from each other. In short, we can assume that due the extremely small size of gases their volume is negligible.

But in reality, an ideal gas does not exist in nature because there are some deviations from ideal gas laws which exist in all the real gases at low temperature and high pressure conditions. In such conditions, the particles start interacting with each other and also start occupying finite space.

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
