From the pulmonary arteries, blood enters the lungs in which gases are exchanged between blood in the capillaries 6. impudently oxygenated blood returns to the heart through the pulmonary veins that lead to the go aside atrium 7. Lastly, blood moves through bicuspid valve & into the left ventricle, accordingly through the aortic valve & and into aorta , then to the rest of the...If you extremity to get a full essay, order it on our website: OrderEssay.net
