Question

A decline of osteoblast activity while osteoclast activity continues at expected levels A decline of osteoclast activity while osteoblast activity continues at expected levels An increase in osteocyte activity while osteoblast activity continues at expected levels An increase in osteocyte activity while osteoclast activity continues at expected levels Which of the following occurs in the cardiac cycle if the impulse triggered at the sinoatrial node never close? Diastole will shorten in duration The ventricles will not contract There will be an absence of systole The atria will not contract. Which of the following structures is found in all cells? Cell wall Mitochondria Nucleus Plasma membrane Which of the following types of cell stimulates other immune cells to attack and destroy? Helper T-cells Plasma cells

Explanation / Answer

Answer to the question, which of the following occurs in Cardiac cycle if the impulse triggered at sino atrial node never close, is option A diastole will shorte in duration.

As you might be aware of the fact that, SA node is considered as the natural pacemaker of our body that sets the rhythm of our pulse and cause the contraction of heart muscles. If these impulses are generated continously leaving no time for heart chambers to relax in between the beats, the diastole duration will shorten, and systole will be prolonged.
