Because of immense pressure from the ventricles, the atrioventricular valves (mitral valve and tricuspid valve) remain closed. The blood pressure of the right atrium is 0-8 mmHg and that of left atrium is 4-12 mmHg. The blood pressure of the right ventricle is 15-25 mmHg (systolic) over 0-8 mmHg (diastolic) and that of left ventricle is 110-130 mmHg (systolic) over 4-12 mmHg (diastolic). The blood from the right atrium will flow back to the vena cavae causing leg swelling. The blood from the left atrium will flow back to the lungs causing pulmonary edema.

Answer:
Plants and animals took up different evolutionary pathway millions of years ago.
In the prebiotic earth, the CO2 levels were insanely high, and the solar input was quite high due to which the initially evolved cells were photosynthetic , so that they can harness the solar energy, and because they need a carbon source, they relied on the Carbon from CO2.
In this process, the atmospheric gaseous content changed, as predecessors of plants gave out Oxygen over millions of years.
Gradually , the atmosphere was now oxygen rich and hence predecessors of animals evolved a mechanism to utilise this oxygen , and as a byproduct started releasing CO2.
Over the next years , these two diverse groups specialised and hence , became increasingly different.
