Step by step
Solved in 2 steps
- Place the following structures in order, tracing the blood flow from the superior vena cava to the heart, to the pulmonary circulation, and out of the heart to the systemic circulation. Start with superior vena cava as number 1. • aorta • aortic valve • bicuspid valve • left atrium • left ventricle • pulmonary capillaries • right atrium • right ventricle • pulmonary arteries • pulmonary trunk • pulmonary valve • pulmonary veins • superior vena cava • tricuspid valveLabel A-J as the following: -right atrium -right ventricle -vena cava -tricuspid valve -bicuspid valve -aorta -left ventricle -left atrium -pulmonary artery -pulmonary semilunar valveThe impression produced by the azygos vein is found on the : *
- Have to label the aorta, capillaries, inferior vena cava, heart, pulmonary artery, pulmonary veinYou are with your great grandma and the rest of your family at a reunion. All of the sudden your great grandma drops to the ground and is not breathing and does not have a pulse. What precautions would you take due to her age during CPR?Venous return to the heart occurs due to pressure created by:
- Coronary artery disease causes: 1) transient ischemic attacks 2) cerebral vascular accidents 3) angina pectorisIdentify the position and location of the heart.Another patient had an abnormal heart sound that indicated a stenotic valve. Define this condition, and contrast it with an incompetent heart valve.
- Place the following structures in order, tracing the blood flow from the superior vena cava to the heart, to the pulmonary circulation, and out of the heart to the systemic circulation. Start with superior vena cava as number 1. aorta pulmonary capillaries right atrium right ventricle pulmonary arteries pulmonary trunk pulmonary valve pulmonary veins superior vena cava tricuspid valve aortic valve bicuspid valve left atrium left ventricleA) A heart murmur indicates some kind of valve __________?__________. B) A heart valve that has a smaller than average opening is said to be ______________?________. (See heart murmur video) https://www.youtube.com/watch?v=dBwr2GZCmQM C.) Describe where you would place a stethoscope to hear the sounds of each of the following heart valves: -Aortic: -Pulmonary: -Tricuspid: -Mitral: D.) At which of the superficial pulse points would you expect to feel the strongest pulse? ___?____.Identify if the statements are TRUE or FALSE. TRUE FALSE STATEMENT The sinoatrial node is situated in the wall of the interventricular septum. Left ventricle ->Left atrium ->Right ventricle ->Right atrium is the correct sequence for blood entering the heart through the vena cavae and leaving through the aorta. The outermost of the three layers of the heart is supracardium. A stenosis of the bicuspid valve might cause blood to back up into the venae cavae. The valve that is located on the same side of the heart as the pulmonary semilunar valve is the mitral valve. Angina pectoris is the comprehensive term for heart attack. Cutting the vagus nerves where they innervate the heart would increase the heart rate. During the ventricular contraction all the blood is forced out of the ventricles. At late diastole, the atria and ventricles are relaxed and the aortic…
