Answer:
Oxygen-rich blood flows from the lungs back into the left atrium (LA), or the left upper chamber of the heart, through four pulmonary veins. Oxygen-rich blood then flows through the mitral valve (MV) into the left ventricle (LV), or the left lower chamber.
OR
The blood becomes oxygenated in the lungs. Oxygenated blood leaves the lung via the pulmonary vein. Blood moves into the left ventricle. Blood is pumped into the aorta, which carries oxygenated blood around the body.

Hormones appear to be influenced by emotion and external behavior. For example, one's activity level may increase the production of a hormone, just as hormones often influence the way an individual feels. Hormones are found to impact behavior indirectly through emotional experiences. For example, an individual may feel a specific way as a result of hormone fluctuations but not behave or act out accordingly. The interaction between the emotion and environment play a large role on how hormonal influences are expressed behaviorally. Hormone production also appears to influence various behaviors.
