Question | Answer |
heart | is a hollow, muscular organ located between the lungs |
epicardium | the external layer of the heart and the inner layer of the pericardium |
myocardium | the middle and thickest of the hearts's three layers and consists of specialized cardiac muscle tissue (myocardial muscle) |
endocardium | which consists of epithelial tissue, is the inner lining of the heart |
atria | are the two upper chambers of the heart, they are the recieving chambers, and all blood vessels coming into the heart enter here |
interatrial septum | separate the atria |
septum | wall that separates two chambers |
ventricles | are the two lower chambers of the heart, they are the pumping chambers, and all blood essels leaving the heart emerge from the ventricles |
ventricle | a normal hollow chamber of the heart or the brain |
interventricular septum | separates the ventricles of the heart |
ventrical | the walls are thicker than those of the atria because they must pump blood throughout the body |
tricuspid valve | controls the opening between the right atrium and the right ventricle |
pulmonary semilunar valve | located between the right ventricle and the pulmonary artery |
mitral valve | known as the bicupid valve, located between the left atrium and left ventricle |
aortic semilunar valve | located between the left ventricle and the aorta |
right ventricle | pumps the oxygen-poor blood through the pulmonary semilunar valve and into the pulmonary artery, which carries it to the lungs |
left ventricle | receives oxygen-rich blood from the left atrium, blood flows out of the lv through the aortic semilunar valve and into the aorta, which carries it to all parts of the body, except the lungs |
pulmonary arteries | carry deoxygenated blood out of the right ventricle and into the lungs |
pulmonary veins | carry the oxygenated blood from the lungs into the left atrium of the heart |
systemic circulation | flow of blood to all parts of the body except the lungs |
left ventricle | oxygenated blood flows out of and into arterial circulation |
right atrium | veins carry deoxgented blood |
electrical impulses | rate and regularity of the heart beat is determined by, from nerves that stimulate the myocarium of the chambers of the heart |
conduction system | electrical impulses are controlled by the sinoatrial (SA) node |
sinoatrial node | located in the posterior wall of the right atrium near the entrance of the superior vena cava |
