wall air barrier

The Ocean of Air - As we know that we cannot live without air even for a single minute. We live in a vast ocean of air, which extends upwards for over 1000 km. Apart from providing us air to breathe, this blanket of air traps the sun's heat that is ..

Gaseous Exchange in the Alveolus of Man The capillaries lining the alveoli have impure blood which has low concentration of oxygen. So, the oxygen from the air easily diffuses into the blood through the thin barrier of the alveolus wall. Similarly since the concen..

The venous capillaries lining the alveoli have impure blood that has low concentration of oxygen and thus lower partial pressure (P O 2 in venous blood is 40mm of Hg). The oxygen of the air in the lungs has higher partial pressure (100mm of Hg) and therefore, easily diffuses into the bloo..

Air as a Mixture - As we know that we cannot live without air even for a single minute. We live in a vast ocean of air, which extends upwards for over 1000 km. Apart from providing us air to breathe, this blanket of air traps the sun's heat that is ..

i) Over-inflation of alveoli ii) Rupture of alveolar walls that form the pulmonary bullae (these are the thin-walled air spaces). iii) Decreased respiratory surface area and pulmonary ventilatio..

Pharynx - Pharynx is the portion of the alimentary canal after the mouth. It is a funnel-shaped passage common to air and food. The gut wall from the oesphagus to the rectum is mainly composed of two regio..

Protoplast is a cell without cell wall. In plants, the cells are invariably surrounded by thick cell wall made of cellulose and pectin. During the process of tissue culture and using it for crop improvement, cell wall acts as a barrier to induce mutations or ..

The distribution of ozone in ionosphere, mesosphere and stratosphere is being depleted. The concentration of ozone is gradually reducing. As the content of ozone is highest in ionosphere and the air itself being very thin, the depletion is negligible in ionosphere. But in mesosphere and s..
