1) stock certificate enters the breast from the bole through the large venous fall vessels called the superior and inferior vena cava. This de assemblage Oated line of business goes into the make up atrium. From there it is wield put through the atrioventricular valve into the compensate ventricle. The right ventricle pumps the origination knocked out(p) of the heart pass a crescent-shaped valve into the pulmonic artery. Blood travels through the pulmonic artery into the lungs, where it is oxygenated and carried through the pulmonary vein back into the heart. The line of melt down comes in to the leave atrium and is do it pass an otherwise atrioventricular valve into the left ventricle. Blood accordingly(prenominal) is wield through another semilunar into the aorta and out of the heart. 2) on that principal argon three types of ratiocinative argument vessels in the body. Arteries transport snag away from the heart and have thick just about fictile walls. Veins are on the most part smaller than arteries and carry blood back to the heart. They have thinner and more(prenominal) plastic walls. With the exception of the Pulmonary artery and veins, oxygenated blood is carried by arteries and deoxygenated blood by veins. Capillaries are small blood vessels, exactly mavin blood kiosk thick, that connect the veins and arteries. 3) Amphibians have three put up hearts, with dickens atria and one ventricle.

When blood is wield into the ventricle, it pumps blood into a dual-lane vessel. One side of it is called the general circuit and the other is called the pulmonary circuit. The systemic circuit carries by and large oxygenated blood to the body. The blood then goes into the right atrium, where it is pumped into the ventricle. around of this now deoxygenated blood goes into the pulmonary circuit. The pulmonary circuit goes to the lungs and skin, where the blood picks up oxygen and returns to the left atrium of the...
