Sinus dysrhythmia
AV valves close during the systole phase of the cardiac cycle.
There is no precipitation during droughts. Water becomes scarce.
Animals take in water. Some of this water returns to the environment through the skin or breathing. Some returns as waste products.
The heart contracts and relaxes during a cardiac cycle.

The basic definition of a breathing cycle, also known as a respiratory cycle, is the working together of the diaphragm and rib muscles to permit inhalation and exhalation, or breathing in and out.
The interval between expiration (breathing out) and inspiration (breathing in) is called the respiratory cycle. During this cycle, the lungs expand and contract to allow air to move in and out of the body.
Alternating current varies in magnitude, and reverses direction every half-cycle. When the current is drifting in one direction we allocate it a 'positive' direction; when it reverses direction we allocate it a 'negative' direction. So the positive half-cycle refers to its variation in current during its forward or positive direction and the negative half-cycle refers to its variation in current during its reverse or negative direction.
Sleep apnea is a serious sleep disorder that occurs when a person's cycle of breathing is interrupted during sleep. Untreated sleep apnea can disrupt the sleep cycle hundreds of times a night.
No, this is not true. Human breathing is part of the carbon cycle. We breathe it in, (and we take it in by eating and drinking) and we breathe it out.

Cycles vary tremendously. A 15 day cycle is possible and most likely a normal variation.
The average volume of gas inhaled in one respiratory cycle is called tidal volume. It represents the amount of air that moves in and out per breath during normal breathing.

If you are charting, in this case, seasonal variation, and keeping track of the number of travelers on the metro during a day's cycle. They will have two peaks, one during morning rush hour and one during afternoon rush hour.
