Alveoli
Capillaries . The smallest of the blood vessels: capillaries.
alveoli
Alveoli are tiny air sacs in the lungs where gas exchange occurs. They remove carbon dioxide from the blood and allow oxygen to diffuse into the bloodstream. This process is essential for maintaining proper oxygen levels in the body and facilitating the removal of metabolic waste.
The air sacs in the lungs where gases move into and out of the blood are called alveoli. They are tiny, thin-walled sacs surrounded by blood capillaries, allowing for efficient gas exchange between the lungs and the bloodstream.
Tiny, delicate air sacs deep within the lungs, where the gas/blood exchange occurs.
Alveoli.
These tiny air sacs are called alveoli. These alveoli are surrounded by capilaries tiny blood vessells. These capilaries have holes that are to small for blood cells to escape but are big enogh for oxygen molecules to pass in to the blood stream and attach to the haemoglobin in your blood.
Tiny air sacs where the exchange of gases between air and blood takes place are located in the lungs. These air sacs are called alveoli and are surrounded by capillaries where oxygen from the air enters the blood and carbon dioxide exits the blood into the air.
Inside the lungs are tiny tubes known as the terminal bronchiole. Within these tubes are thing air sacs which transfer oxygen directly into the blood and remove carbon dioxide.
the air goes into your lungs. In your lungs there are billions of tiny air sacs. Surrounding each air sac is a network of blood capillaries. The air sacs and the blood capillaries are separated by a thin membrane. Across this membrane the air sacs give the blood capillaries oxygen and they blood capillaries give the air sacs carbon dioxide. We breathe out this carbon dioxide!
