1 A high proportion of production costs is cash costs. 2  The only two costs in Table 1 that clearly are not cash costs are machinery depreciation ($60 per acre) and building depreciation ($7). 3  For cash rent farmland, only 9% of costs are non-cash ($67 depreciation / $872 total costs).
The right atrium receives oxygen-depleted blood from the body through a large vein called the vena cava, then pumps it to the right ventricle below. The right ventricle receives blood from the right atrium and pumps it through the pulmonary artery to the lungs to get oxygen. The left atrium receives oxygen-rich blood from the lungs through the pulmonary veins, then pumps it to the left ventricle below. The left ventricle receives blood from the left atrium, then pumps it out through a large artery called the aorta. The aorta branches off into other, smaller arteries that carry the oxygen-rich blood to the rest of the body.
Overview. The left atrium is the chamber of the heart that receives oxygen-rich blood from the lungs. Blood moves from the left atrium, through the mitral valve, into the the main pumping chamber of the heart--the left ventricle, and then out to the body.Any condition that increases pressure in this portion of the cardiac system can lead to enlargement of the left atrium.verview.
