The answer is atrial depolarization. The P wave of a normal electrocardiogram specifies atrial depolarization.  In addition, depolarization happens in the four compartments of the heart which is both atria first and in both ventricles. The sinoatrial or as called as SA node on the wall of the right atrium starts depolarization in the right and left atria that can cause the contraction in which it is symbolized by the P wave on an electrocardiogram.

Which organ produces estrogen and progesterone?
NemiM [27]
<span>The ovaries produce estrogen and progesterone in women. Both play an important role in the menstrual cycle: estrogen stops FSH production and stimulates LH release by the pituitary gland. Progesterone maintains the uterus’ lining. Men also produce estrogen, though at lower levels, and this is done through changing testosterone into estrogen with an enzyme.</span>
