The Diaphragm.
Respiration. The diaphragm is a sheet of muscle separating the chest cavity from the abdominal cavity which, when relaxed, domes upwards; on breathing in the diaphragm contracts & flattens down, thus increasing the capacity of the chest, and causing air to be drawn into the lungs.When the diaphragm contracts that causes the volume of the lungs to increase. When the lung volume increases, the air pressure drops causing air to come in from outside (inhaling). When the diaphragm relaxes, the process is reversed. Lung volume decreases, air pressure builds, and air is forced out (exhaling).
When you inhale, oxygen fills your lungs. Next the oxygen diffuses out of your lungs into your bloodstream. The diffusion of oxygen from the lungs causes less pressure in your lungs signaling your brain that you need to inhale.
the diaphragm contracts and theocratic volume increase. for Plato d
it contracts, pulling downwards to increase the volume in the chest.
An increase in volume or velocity of the water will increase erosion
yea,by retention water ,it increase blood volume,which ultimately increase blood pressure..
an increase in volume and/or a decrease in mass
"When smooth muscle contracts, the cavity of an organ alternately becomes smaller or enlarges so that substances are propelled through the organ along a specific pathway"Smooth muscle
heat causes gases to expand
heat causes gases to expand
The heart itself is a muscle. These contractions generate the force, which is the force of contraction, which results in a decrease in the venticular volume in case of the ventricles or decrease in the atrial volume in case of the atria, this is followed by an increase in the venticular or atrial pressure respectively. which allow ejection of oxygenated and deoxygenated blood to flow into and out of it to circulate throughout the body. thus giving you air to breathe and blood to pump to stay alive.
