Answer:
Cardiac tamponade condition reduces the ability of heart contraction.
Explanation:
Cardiac tampondae is a medical condition in which the pericardium sac fills with blood and causes various health related problems in the individuals.
Individuals with cardiac tampondae suffers from the low blood pressure, anxiety, shortness of breath and pain in chest, neck and shoulder. The serious condition of cardiac tampondae increase the pressure on heart and reduces the ability of heart to contract.
Single-photon emission computed tomography (SPECT)
Answer:
The correct answer will be option-B.
Explanation:
Papillary muscles are the muscle present in the ventricle of the heart to which chordae tendinae of the aortic valves gets attached.
The number of papillary muscles varies in both the ventricles as in the right ventricle, three papillary muscles are present whereas in the left ventricle two muscles.
They play an important role in the closing of the AV valves as ventricular contraction causes the chordae tendinae to contract which in turn contract the papillary muscles thereby closing the AV valve and prevent back-flow of the blood to the atria.
Thus, Option-B is the correct answer.
papillary muscles by chordae tendineae. During the relaxation phase of the cardiac cycle, the papillary muscles are also relaxed and the tension on the chordae tendineae is slight (see Figure 12b). However, as the myocardium of the ventricle contracts, so do the papillary muscles. This creates tension on the chordae tendineae (see Figure 13b), helping to hold the cusps of the atrioventricular valves in place and preventing them from being blown back into the atria.
