When respiratory gases move across the membrane from higher concentration to lower concentration is called?
ventilation
Which transport mechanism causes the respiratory gases to move across the alveolar pulmonary capillary membranes?
Diffusion
How does exchange of gases takes place in unicellular organisms?
In unicellular organisms, gases are exchanged through simple diffusion across the cell membrane. Oxygen from the environment diffuses into the cell, while carbon dioxide produced by the cell diffuses out. This process is driven by concentration gradients, where gases move from areas of higher concentration to areas of lower concentration.
What does cilium do in?
Cilia help to move substances across the surface of a cell. They can either help propel fluids over the cell's surface, as in the respiratory tract, or help move the cell itself, as in the case of sperm cells. They also play a role in sensory functions in some cells.

How does the material move from the respiratory system to the circular system?
Material moves from the respiratory system to the circulatory system by diffusing across a membrane in the air sacks called alveoli.
What is true about the density of gases as you move farther away from earths surface?
it remains unchanged
What is the process called where gases move between the ocean's surface and the atmosphere?

How does materials move from the respiratory system to the circulatory system?

Why does air move in or out of your respiratory system?
