How does ventilation help maintain a difference in oxygen concentration?

As it circulates, the oxygen diffuses into the blood via the alveolar wall, this then transfer the oxygen to the red blood cells, as diffusion occurs at this point, oxygen diffuses from a high concentration to a low concentration, so the oxygen diffuses into the blood whereas the CO2 diffuses into the alveoli and then out of the mouth when we expire.

Why do multi-cellular organisms need a ventilation system?
A ventilation system is needed in order to obtain oxygen for living organisms and to get rid of carbon dioxide. Surface diffusion utilized by many smaller organisms is not sufficient in supplying the oxygen needs of the body. It is also needed to maintain a concentration gradient in the alveoli.

Is the outdoor oxygen level greater then the indoor level?
With proper ventilation there will be little difference. Without ventilation the oxygen level will decrease slightly if the room is occupied.
Why do you need ventilation on a plane?
Ventilation is important on a plane to compensate for air pressure as the plane is in a high altitudes and also to maintain suitable temperature and oxygen levels,
What is the difference between breathing respiration and ventilation?
respiration is the process of yainhaling oxygen to the body and provide the cells.
A mammal uses only 1 to 2 percent of its energy in ventilation while a fish must spend about 15 percent of its energy to move water over its gills Explain this huge difference?
i think it because in water oxygen dissolved in the water and it is harder than oxygen concentration in the air.
What is the a-v O2 difference is?
The amount of oxygen taken up by the tissues in a muscle. It is the difference between oxygen concentration in the arteries and the oxygen concentration in the veins.ie. if your blood carries 20ml of oxygen per 100ml of blood and the muscle takes up 6mls of oxygen, 14mls of oxygen leaves the muscles into the veins.therefore, VO2-diff = 20ml-6ml = 14ml.
For a fresh water lake to maintain a healthy 0.225 mM or higher concentration of dissolved oxygen required to maintain a healthy aquatic system what is maximum temperature of H20?
For a healthy environment, the temperature of a body of water needs to be inversely proportional to the concentration of dissolved oxygen in it. The higher the oxygen level, the temperature needs to be lower to promote fish growth.
What is ventilation in a human body?
Ventilation is a process humans rely on to maintain high oxygen and low carbon dioxide concentrations at the gas exchange surface. The process that ventilates lungs is breathing. Humans ventilate the lung by negative pressure breathing
How does ventilation occur?
Pulmonary ventilation occurs as a person inhales and exhales air and air is exchanged between the atmosphere and the alveoli of the lungs. During this, the pulmonary capillary blood gains oxygen and loses carbon dioxide.
What is the percent oxygen concentration if the water temperature is 10 degrees celsius and the oxygen concentration is 12 ppm?
The concentration of oxygen in water is 88,88 %.
Why do animals need ventilation?
since fish live in water and it face some problems in ventilation where it getoxygen from water where oxygen concentration of oxygen in water is small hence large amount of water must pass to the gills so as to supply sufficient oxygen for metabolic activities on doing that fish use more energy since water is very viscous which make it not easily to flow in the gill so fish use more energy to over come this friction
