Select the best answer or answers from the choices given: In the heart, which of the following apply? (1) Action potentials are conducted from cell to cell across the myocardium via gap junctions, (2) the SA node sets the pace for the heart as a whole, (3) spontaneous depolarization of cardiac cells can occur in the absence of nerve stimulation, (4) cardiac muscle can continue tocontract for long periods in the absence of oxygen. (a) all of the above, (b) 1, 3, 4, (c) 1, 2, 3, (d) 2, 3.
"Isovolumetric contraction" is a phase in the cardiac cycle in which the volume of a particular heart chamber___(decreasing, increasing , not changing) is and the pressure is____ (decreasing, increasing , not changing) The sarcomeres of a healthy human heart are always operating ________ their optimal length. Group of answer choices at above below
Identify if the statements are TRUE or FALSE. TRUE FALSE STATEMENTS When the atrioventricular bundle is completely interrupted, the ventricles typically contract at 30 to 40 beats/minute. The left ventricular wall of the heart is thicker than the right wall in order to pump blood with a greater pressure. Impulses through the conduction system of the heart follow the ordered path SA Node ->Conduction Myofibers ->AV Bundle ->AV Node.
Describe the Blood flow into the heart starting by the superior and inferior Vena Cava to the ascending aorta. (Write the blood is coming from (anatomical structure) and then pass to (anatomical structure) and so on. Do not forget to mention where the blood is oxygenated.
Drag the steps below and place them in the order of blood flow through the heart. First: Second: Third: Fourth: Fifth: Sixth: Seventh: Eighth: Ninth: Tenth: Flows through right atrial ventricular valve (tricuspid) Blood back flowing in aorta toward heart enters coronary circulation Flowing into the right atrium Out the aortic semilunar valve into the aorta Back to heart through the pulmonary veins to the left atrium Into the right ventricle Into the left ventricle Left atrium through left atrial ventricular valve (BICUSPID OR MITRAL) Out the pulmonary semilunar valve through the pulmonary arteries to lungs To the body through the aortic branches
A premature ventricular contraction (PVC) indicates which of the following Group of answer choices an extra ventricular contraction arial tachycardia ventricular fibrilation none of the above
The cardiac cycle includes all the events associated with the flow of blood through the heart during a single complete heartbeat. Indicate if the following statements are True/False. | T wave marks the beginning of ventricular relaxation.
What are the difference between contractile cells of the heart and electrical cells responsible for generation and conduction of impulses. Why is the cardiac action potential propagated more slowly in an AV node cell than in an atrial or ventricular myocyte? How are the channels and ions that are responsible for depolarization and repolarization work? How can be AV conduction affected by hypokalemia?
Show a photo of an intact,undissected heart with attached blood vessels and label fully all chambers, arteries and veins. Label and indicate the coronary vessel branches that remain on the surface of the heart. (Reality photo of heart plz????)
Consider the circulation of blood through the heart. Put the structures in the order that blood flows through them, starting with the superior and inferior venae cavae|(#1) and ending with the ascending aorta (#14).
which of the following is true for the ejection phase of the cardiac cycle select all that apply ventricular volume decreases ventricular pressure increases ventricular volume increases av valves open
The first sound of a cardiac cycle occurs when the _____ and ______ (select them in alphabetical order) are closing. The second sound of a cardicac cycle occurs when the _______ and ________ (select them in alphabetical order) are closing. Word Options for Blanks: (some may not be used, some may be used more than once) aorta aortic valve bicuspid valve coronary sinus inferior vena cava left atrium left ventricle pulmonary arteries pulmonary trunk pulmonary valve pulmonary veins right atrium right ventricle superior vena cava tricuspid valve
