What does the alveoli do when you breathe out?
It gives off the Co2 which is produced in the blood vessels covering the alveoli
Where are two main areas where oxygen enters the blood vessels?
skin surface (integumantary system) and the lungs (alveoli) .
What are the very small blood vessels that cover the alveoli?
The tiny blood vessels that surround the alveoli arecalled alveolar capillaries
The blood vessels surrounding the alveoli are?
capillaries
What type of blood vessels surrounds the alveoli?
The smallest blood vessels of the body = capillaries
What passes from the alveoli in the lungs into the blood vessels?
ravioli
What is the lining of the blood vessels made up of?
Alveoli
What factors are important for gas exchange?
1. The blood vessels are completely surrounding the alveoli for easy diffusion into the blood vessels 2. The alveoli and the blood vessels are made up of a very thin layer of cells. a single layer of simple squamos epithelium. For easy diffusion 3. There is a moist layer layering the alveoli which the gases dissolve into. This aids diffusion. 4. The blood vessels are very thin, this ensures that the red blood cells enter them in a single file row. This enables maximum diffusion. 5. The shape of the red blood cells is flat, this is increases surface area for maximum absorption. 6. The alveoli itself are round, balloon shape. This also increases surface area for maximum absorption.
What are empty spaces in alveoli?
When air enters the empty alveoli in the lungs they become inflated. Now the blood vessels inside the alveoli can take oxygen from this air and put carbon dioxide into it.
What are the characteristic of alveoli in the lungs?
Large surface area due to the combined spherical shape (600 million alveoli = 80 m2) Flattened epithelial cells of alveoli and close association with capillaries Short diffusion distance from alveoli to blood (0.5-1.0 um) Dense capillary network Moist surface for the solution of gases
What type of blood vessels surrond the alveoli?
Capillaries - Apex Cheater /Thugs
How does the alveoli work with other organs?
The alveoli are completely covered in blood vessels (capillaries). The walls of the capillaries are extremely thin and the distance between air and blood is only 0.3μm. This means that O2 has no distance to travel to get into the blood. The alveoli increase the surface area hugely. Humans have 300 million alveoli in both lungs giving a total surface area of 80 m2 (The skin is 2m2).
