When body of air of a particular region or location reflects the temperature and other climatic condition of land and water is called as air mass. The air exchanges heat with the land or water, until the temperature of the air matches with that of the surface below it. A maritime polar air mass is the air mass that forms over the northern Atlantic and the northern Pacific oceans. This is responsible for bringing cold air mass to these two oceans.

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.
