As the exercise progresses, muscular activity increases venous return. This increases the pre-load on the right ventricle. During venous exercise, the rhythmic pump of the muscles facilitates venous return by forcing the blood through one way valves that lead to the heart. Additionally, increased lung activity which creates a change in thoracic pressure that draws blood towards the heart. Regular exercises improves the venous return by increasing total blood volume, increasing end diastolic volume and increasing the size and contractile strength of the heart muscle.

water is the essential element for life. about 71% of the total Earth is covered by water, mostly in the form of rivers, sea, oceans and glaciers. similarly, the water cycle defines the processes through which the water on earth remains balanced for all living and non living things. there are various stages which occurs in equilibrium, such include;
1. Evaporation
2. Transpiration
3. condensation
4. precipitation
water evaporates, turns into clouds and condense to make rain and snow and came back to earth in the form of precipitation.
however there are times when the process of water cycle gets disrupt causing famine, drought, floods, tsunami etc, which is extremely dangerous for life on Earth.
Archaebacteria move by using the form of a flagellum to propel a themselves.
