Cardiac Cycle The cardiac cycle describes the coordinated and rhythmic series of muscular contractions associated with the normal heart beat. The cardiac cycle can be subdivided into two major phases‚ the systolic phase and the diastolic phase. Systole occurs when the ventricles of the heart contract. Accordingly‚ systole results in the highest pressures within the systemic and pulmonary circulatory systems. Diastole is the period between ventricular contractions when the right and left ventricles

The brain is a very complex system. As our body changes through the years‚ so does our brain. When we are infants‚ our brains are reworking.

Are neurons are getting bigger‚ and are working more efficiently. Causing us to gain connection between hearing to vision. Near the end of the early stages‚ you would be two years old‚ and your brain will be about

rock cycle operates. How do rocks metamorphose at destructive plate boundary? Rock cycle is a cycle that describes how rocks are transformed. Igneous rock can change into sedimentary rock or metamorphic rock. Sedimentary rock can change into metamorphic rock or into igneous rock. Metamorphic rock can change into igneous or sedimentary rock. Besides‚ metamorphism at the destructive plate boundaries creates different characteristics of rocks.

This heat energy causes the water in the world ’s oceans‚ lakes‚ etc. to warm and evaporate. As the water is heated‚ it changes its phase from liquid to gas. This gas is called water vapor and this process is called
