Speed: The time rate of change of position of a body in any direction is known as its speed.
It is measured by the ratio of the distance by a body to the time in which this distance is covered
i.e. Speed = distance/time
Uniform Speed: A body is said to be moving with uniform speed, if it covers equal distances in equal intervals of time, however small these intervals may be.
Variable Speed: A body is said to be moving with variable speed if it covers unequal distances in equal intervals of time, however small these intervals may be.
Average Speed: Average speed of a body is defined as that uniform speed with which it covers the same distance in a given interval of time as is actually covered by it in the same interval of time while moving with variable speed.

A valve is a membranous structure present in a hollow organ. It folds or closes to prevent the return flow of the body fluid passing through it. The valves present in between the auricles and ventricles are meant to prevent the back flow of blood from the ventricles to auricles. These also form the passage for blood to pass from the auricle to ventricles.

An aquifer is an underground layer of water-bearing permeable rock, rock fractures or unconsolidated materials (gravel, sand, or silt) from which groundwater can be extracted using a water well. It is a porous substrate. When water can flow directly between the surface and the saturated zone of an aquifer, the aquifer is unconfined. The deeper parts of unconfined aquifers are usually more saturated since gravity causes water to flow downward.
