Answer:
Amount of air inhaled or exhaled per breathing stroke is called as tidal volume. Tidal volume is 400 ml for women while for men it is 500 ml.
Explanation:
In respiration, tidal volume is defined as the volume of air that a person inhales or exhales in one stroke of normal breathing.
The tidal volume varies in adult men and women. In resting condition, tidal volume is 400 ml for women while for men it is 500 ml.
This tidal volume varies with the requirement of the body. During intense physical exercise the amount of gas intake increases in order to full fill the requirement of body and hence the tidal volume increases.
Earthquake
- has hypocenters and epicenters
- may be preceded by ground deformation
- measured by magnitude and intensity scales
- most frequent in alaska and volcanoes
Volcanoes
- cannot be predicted accurately
- measured by an explositivity index
- cause a visible fume or steam cloud or both
- often cause steam or gas to erupt in the atmosphere
- caused by molten rock erupting through earth’s surface
<span>Cell membrane plays an important role in maintaining the homeostasis by controlling the substances that penetrate the cell, either entering the cell, or leaving the cell. Since the cell membrane is a phospholipid bilayer, it can control the transition of water and ions.</span>
<span>Mannitol reduces the intracranial hypertension in patients with head injury. this chemical which is a sugar- alcohol lowers the viscosity of the blood and thus reducing the blood volume. Head injury may lead to increased intracranial pressure and volume. It is also believed that mannitol acts by reducing brain water.</span>
