Gas exchanges occur by simple diffusion through the respiratory membrane -- oxygen passing from the alveolar air into the capillary blood and carbon dioxide leaving the blood to enter the gas-filled aveoli.

What system takes in oxygen and eliminate carbon dioxide?

The respiratory system takes in oxygen through the lungs and eliminates carbon dioxide through exhalation. Oxygen is exchanged with carbon dioxide in the alveoli of the lungs during the process of respiration.


How do the heart and lungs work?

When we breathe in our lungs fill with oxygen rich air. Membranes in the lungs exchange the oxygen from the air with carbon dioxide in the blood. Then we breathe out the spent air to inhale fresh. The blood, now replenished with oxygen, is pumped by the heart through the arteries to all cells in the body where the oxygen is exchanged with the cells for carbon dioxide and returned through the veins to the lungs.


Is oxygen and carbon dioxide exchanged in the human body?

Yes, oxygen and carbon dioxide are exchanged in the human body through the process of respiration. When we inhale, we take in oxygen from the air which is used by our cells for energy production. Carbon dioxide, a waste product of this process, is then expelled from the body when we exhale.

Does sweat contain oxygen or carbon dioxide?

No, sweat does not contain oxygen or carbon dioxide. Sweat is primarily composed of water and electrolytes such as sodium and potassium. Oxygen and carbon dioxide are exchanged through the lungs during respiration.


What remove carbon dioxide and brings oxygen to the blood?

The respiratory system removes carbon dioxide from the blood and brings oxygen into the blood. This process occurs through the lungs, where oxygen from the air is exchanged for carbon dioxide in the blood.


What are two substances that are exchanged across membranes of red blood cels and muscle cells?

Oxygen and carbon dioxide are two substances exchanged across the membranes of red blood cells and muscle cells during respiration. Oxygen is taken up by red blood cells in the lungs and delivered to muscle cells for energy production, while carbon dioxide produced by muscle cells is carried away by red blood cells to be exhaled from the body.
