The organelle responsible for keeping the cell clean is the cell membrane.
I think it’s C explanation : i learned this a while ago
No the amplitude of each waves are different on different cardiac cycles.
<u>Explanation:</u>
- The PQRST waves are used to represent the atrial and ventricular depolarization and repolarization. These waves are reflected in ECG.
- In this as the series, p occupies the first place then QRS complex and at last T wave. In the QRS wave complex, R wave is said to be the largest wave.
- The direction and amplitude of r wave depend on the electrical picture. The R wave represents the ventricles depolarization so it is the largest wave.
The active hyperemia is the consequence of dilation of arterioles and the resultant influx of blood in the capillaries, which occurs during blushing or excercise.
<u>Explanation:</u>
The rise in organ blood circulation correlated with an organ or tissue having elevated metabolic activity is understood as active hyperemia. An illustration of active hyperemia is the rise in blood flow that follows muscle contraction, also named skeletal muscle activity or responsive hyperemia.
It typically occurs when blood is needed by the organs more than normal. Your blood vessels are expanding to improve blood running in. Reactive hyperemia is the blood circulation reaction to occlusion of blood flow, while active hyperemia is the blood flow result of increased metabolic activity of the tissue.
