The human heartbeat has two phases. The systolic phase corresponds with contraction, and the diastolic phase with relaxation.
The two phases of the heartbeat are systole (contraction phase) and diastole (relaxation phase).
Diastole (relaxation) Systole (contraction)
Diastole is the relaxation phase. Systole is the contraction phase. If you put these phases together you have the Cardiac Cycle...
The period of time between the beginning of one heartbeat and the start of the next is known as the cardiac cycle. It consists of two phases: systole (contraction of the heart muscles) and diastole (relaxation of the heart muscles).
The changes in shape that the moon goes through are called phases.
The Medical Device Amendment Act in 1976 thus empowered which group to regulate medical devices during their design and development Phases?
The moon phases are called "phases" because they refer to the different shapes or appearances of the Moon as seen from Earth at different points in its orbit. These phases are a result of the changing relative positions of the Sun, Earth, and Moon.
