What is the function of a leafs stomata?
Help in gaseous exchange
How does thin walls help the lungs in gaseous exchange?
No, the alveoli wall should be as thin as possible, i.e. one cell layer thick, in order to make the diffusion distance for gas exchange as short as possible.
How is the trachea adapted for gas exchange in lungs?
It isnt. There is no gas exchange in the trachea this takes place at the alveoli.
What are the small air sacs in the lungs?
These small sac like structure are known as the alveoli . The alveoli help in the exchange of the gases, oxygen & carbon-dioxide,Lungs contain alveoli to increase the surface area and to easily transport oxygen to the blood vessels which surrounds the air sacs. Also, the air sacs have a thin film of oxygen which helps to absorb oxygen quickly.
What are the characteristics of the alveoli that help with its function?
gas exchange is the intake of the oxygen and the let out of the carbon dioxide
What is a functions of alveoli in speech organ?
it help in the exchange of o2 in blood capillary and co2 from blood capillary into alveolus
Why do you have alveoli?
Because they help gas exchange, and without them we'd die, and also we couldn't be able to let urine pass out
What is the similarities between gills and lungs?
They both help the organism to have gaseous exchange with its surrounding
Why are lungs divided into small sac like structure?
They are structured like they are because the help us to breathe. The reason they have alveoli is because they help us with gas exchange
Why is the alveolus important to the breathing system of humans?
Alveoli in the lungs are important because they help with the transportation of oxygen to the blood. They are also called the pulmonary alveoli.
How do alveoli help us to breathe?
They provide a space for the gas exchange to occur where carbon dioxide is dropped off and oxygen is picked up by the circulatory system.
What are two adaptations that plants developed to help protect and support plants while living on land?
1.Development of stomata for gaseous exchange and 2. vascular tissue for transportation
