EXPLAIN why it is that when you go swimming, your fingertips shrivel up after you’ve been in the water for a while. Be as descriptive as possible (do not just provide a one word answer). T / F The sinoatrial node is found in the HEART and not at the center of the pulmonary veins. T / F the heart. Purkinje fibers are responsible for attaching blood vessels to T / F ALL Human Beings (including females) have a heart. Which type of blood vessel (artery or vein) has valves? ___________ Which side of the heart (left or right) has deoxygenated blood? __________ Blood enters the ________ atrium of the heart via the vena cavas, it then flows through the __________ valve before entering the _________ ventricle. From there it enters the pulmonary __________ and gets sent to the lungs. It then returns to the heart via the pulmonary __________, this time though, it enters the _________ atrium. It then passes through the ___________ valve and enters the __________ ventricle, where its pumped into the ________ (the bodies largest artery).
