For a project a needed to ask 25 people: Do you think vegetarianism is good for the environment ?

Vegetarianism while it may be slightly better for the environment, it is not as good for you as your not getting much protein (assuming that you eat a balanced meal). By being vegetarian, your carbon footprint on the planet is reduced.

Hope that helps

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.
