In the aorta, Select one: a. the resistance to blood flow is high, but velocity of blood flow is low. b. the velocity of blood flow is high, but blood pressure is low. c. velocity is diminished because the total cross-sectional area is small. d. the blood pressure and blood velocity are both high. e. the resistance to blood flow and the blood pressure are both low.
This abnormal ECG indicates: A ventricular fibrillation B premature ventricular contractions (PVCs) C ST-segment elevation D premature atrial contractions (PACS) hahah
1. In the flow chart provided below, label the structures that lie along the path of blood flow in the heart OR make a similar diagram of your own showing the path of blood in a linear fashion. The top row of boxes (blue) refer to the right side of the heart (unoxygenated blood) and the bottom row of boxes (red) refer to structures in the left side of the heart (oxygenated blood.) (b) 2. Label all the structures indicated by the lines in the diagram below.
All of the following are correct about the isovolumetric contraction, except ____________. A. This phase of the cardiac cycle begins with the appearance of the QRS complex of the ECG, which represents atrial repolarization and ventricular depolarization B. It represents the time period between the closure of the AV valves and the opening of the aortic and pulmonic valves, ventricular pressure rises rapidly without a change in ventricular volume C. The rate of pressure increase in the ventricles is determined by the rate of contraction of the muscle fibers, which is determine by mechanisms governing excitation-contraction coupling D. Ventricular chamber geometry changes considerably as the heart becomes more spheroid in shape; circumference increases and atrial base-to-apex length increases
Mark the following coordinates on the image about: 1. repolarization of the ventricles 2. conduction through the atrioventricular node, 3. depolarization of the ventricles and repolarization of the atria. 4. First deflection corresponding to the movement of current when the atria depolarize
Can you help with number 12 This is not and will not be graded
On an ECG, if every other P wave (e.g., every even is, and every odd is not) is NOT followed by the QRS complex, this is: A. first degree AV block B. second degree AV block C. third degree AV block D. atrial fibrillation
The atrioventricular valve on the same side of the heart as the origin of the aorta is the _____ valve. A aortic semilunar B tricuspid C bicuspid D pulmoary semilunar
The period between the filling of the ventricles and the opening of the semilunar valves in the cardiac cycle is called: A. Atrial Systole B. Isovolumetirc ventricular contraction C. Isovolumetric ventricular relaxation D. Passive ventricular filling
Which of the following is/are true concerning the opening and closing of the cardiac valves? A. valves operate according to the pressures on either side of the valve B. valve operation is constantly being controlled by the medulla oblongata C. valve operation is determined directly by the cardiac action potential (electrical currents control the opening and closing of the valves.) D. valve operation is directly controlled by the papillary muscles within the ventricular wall. E. None of the above is correct.
Looking at the wiggers diagram. Notice, time stamp 370-410msec in the left ventricular volume the ventricles are in diastole, but there is no rise in the volume of blood, till the making “F”. Why is that?
