the Note
... The air breathed into the alveoli contains a higher concentration of oxygen than the blood. The steep concentration gradient results in diffusion of oxygen from the air in the alveoli to the blood capillaries. Oxygen dissolves in the moisture lining each alveolus and diffuses through the thin wall o ...

The Human Respiratory System
... The inner surface of the thoracic cavity and the outer surface of the lungs are lined with pleural membranes which adhere to each other. If air is introduced between them, the adhesion is broken and the natural elasticity of the lung causes it to collapse. This can occur from trauma. And it is somet ...

Organisms at high altitude
.jpg?width=300)
Organisms can live at high altitude, either on land, or while flying. Decreased oxygen availability and decreased temperature make life at high altitude challenging. Despite these environmental conditions, many species have been successfully adapted at high altitudes. Animals have developed physiological adaptations to enhance oxygen uptake and delivery to tissues which can be used to sustain metabolism. The strategies used by animals to adapt to high altitude depend on their morphology and phylogeny.
