- Which of the following statements concerning the heart is true 1. The intraventricular septum prevents the electrical activity from stimulating the heart in a superior to inferir direction 2. The bundle of his is located in the intraventricular septum 3. The bundle branches stimulates the ventricles in ann inferior to superior direction 4. Both A and B 5. All of the aboveWhich of these will increase the heart rate? sympathetic stimulation of SA node parasympathetic stimulation to the SA node the application of adrenalin (epinephrine) to the SA node O A and C O All of the aboveA patient has a condition in which the SA node is no longer functioning. The atrioventricular (AV) node is now setting the pace and rhythm for the heart. What difference would you expect to see in the ECG of this patient? Group of answer choices P wave would be much larger than normal there would continue to be a normal sinus rhythm QRS complex would be absent the rhythm would be slower
- Which of these accounts for the similarity between the P wave duration and the QRS complex duration despite the ventricle being much larger than the atria? Group of answer choices The His-Purkinje system has a faster conduction velocity than the atrial system The atria contain the same volume of blood as the ventricles Gravity increases the ventricular conduction velocity The rate of phase 4 depolarization is similar in all the conducting cells of the heartWhich of the following is not correct regarding the heart? ventricular fibrillation occurs from autorhythmic cells firing out of sequence the majority of cells are contractile, very few are autorythmic the atria and the ventricles contract at the same time both ventricles contract almost at the same timeOrder the contraction of the heart involving the nodes starting with blood entering the right atrium and left atrium. Sinoatrial node signals contraction to surrounding tissues Left atrium contracts and Atrioventricular node is triggered Ventricles contract sending blood to the lungs and body Blood enters the right and left atrium (start) Punkinje fibers transports a signal to the Right and Left Ventricles
- The marks a spot of dead myocardial cells. How does this change the depolarization and muscle contraction patterns in specific locations of the heart? M Pulmonary semilunar valve Aortic semilunar valve Right AV- valve Left AV valveWhy is the wall of the left ventricle thicker than the wall of the right ventricle? View Available Hint(s) The left ventricle pumps more blood than the right ventricle. The left ventricle pumps blood at a higher pressure than the right ventricle. The left ventricle contracts before the right ventricle does. The left ventricle pumps oxygen-rich blood, while the right ventricle pumps oxygen-poor blood. O The left ventricle pumps blood at a higher temperature than the right ventricle.rses/50898/quizzes/418452/take These These blood vessels are the [ Select ] arteries and the coronary [Select] capillary [ Select ] to pulmonary carotid cardiac 27 OTA stv MacBook Air 80

The outer layer of the sac is fibrous connective tissue layer called the The is a serous connective tissue layer that's directly adhered to the heart's surface. Between these two layers is the , which is filled with pericardial fluid and serves to cushion the heart. The is the thick muscular layer of the heart that makes-up the bulk of the chamber walls. It is thicker in heart chambers that pump blood farther distances, such as the left ventricle, and thinner in the atria that do not pump blood very long distances. The innermost heart layer is the , which has a slippery surface to prevent blood from sticking to the heart chamber walls.Put these autorhythmic cells into the correct order for conveying electrical signals through a normal heart. 1.
