It is very important that they cover you alveoli
The tiny blood vessels that surround the alveoli arecalled alveolar capillaries
The correct order is:nosetracheamain bronchusbronchi (two) which is part of the lungsbronchioles - tinier than the bronchialveolismall capillaries surround each alveoli and cover each alveoli's surface-- CO2 passes from the alveoli to the venous blood supply; the blood passes O2 to alveoli and into the arterial blood supply

It means that low radiation is reflected by a or its surface.
There are about 300 million alveoli in each of your lungs. These tiny air sacs provide an ideal site for the diffusion of gases into and out of the blood.The alveoli have a very large surface area. In fact if all of the alveoli in your lungs were spread out flat they would cover the area of a tennis court. This large surface area is the result of all the alveoli being small spheres. It is another example of the importance of the surface area: volume ratio.
There are about 300 million alveoli in each of your lungs. These tiny air sacs provide an ideal site for the diffusion of gases into and out of the blood - also known as gaseous exchange. The alveoli have a very large surface area - in fact if all of the alveoli in your lungs were spread out flat they would cover the area of a tennis court. This large surface area is the result of all the alveoli being small spheres - it is another example of the importance of the surface area- to-volume ratio. If your lungs were simply two large balloon-like structures, the surface area wouldn't be big enough for you to get enough oxygen by diffusion to supply the needs of your cells. But each alveolus is a very tiny sphere. The smaller the radius of a sphere, the bigger the relative surface area - halving the radius increases the relative surface area by a factor of four. The millions of tiny alveoli in the human lungs are a very effective adaptation which provides a huge surface area for gaseous exchange into and out of the blood. The alveoli have a good air supply from the bronchioles and a rich blood supply. This is vital for successful gaseous exchange because it maintains a steep concentration gradient for oxygen from the air in the alveoli to the blood, and for carbon dioxide from the blood to the alveoli.

Capillaries cover the alveoli in order to maximize the area for gas exchange between the lungs and the blood. Carbon dioxide is released from the blood through the capillary walls and into the alveoli, while oxygen is picked up from the alveoli through the capillary walls and into the blood.
A ground cover is a lowing growing plant(s) that spreads quickly. Grass is a common ground cover plant, but there are many flowering plants that are used for ground cover. The purpose of a ground cover is to prevent erosion and add beauty.
Low cloud cover can act like a blanket, trapping the heat radiated by the Earth's surface and preventing it from escaping into the atmosphere. This phenomenon, known as the greenhouse effect, causes the surface temperature of the ground to increase on calm clear nights when low clouds move overhead.
