WebThe respiratory surface must be kept moist in order for the gases to dissolve and diffuse across cell membranes. Organisms that live in water also need a way to obtain oxygen. Oxygen dissolves in water, but at a lower concentration in comparison to the atmosphere, which has roughly 21 percent oxygen. WebThe primary function of the respiratory system is to deliver oxygen to the cells of the body’s tissues and remove carbon dioxide, a cell waste product. The main structures of the human respiratory system are the nasal cavity, the trachea, and lungs. All aerobic organisms require oxygen to carry out their metabolic functions.

Respiratory gasses can dissolve into this fluid and easily diffuse into surrounding tissues because the tracheoles have such thin walls. The fluid lining the tracheoles normally fills the ends of these small tubes.

Diffusion is a process in which transport is driven by a concentration gradient. Gas molecules move from a region of high concentration to a region of low concentration. Blood that is low in oxygen concentration and high in carbon dioxide ...

WebFick's Law states that: The larger the area and difference in concentration and the thinner the surface, the quicker the rate. This means that water, a small molecule at a higher concentration inside the body than outside, will continually diffuse out of the animal and evaporate away. This makes the diffusion surface moist.
