10 Questions
What is the respiratory system and what is its function?
The respiratory system is a biological system consisting of specific organs and structures used for gas exchange in animals and plants. Its function is to facilitate the exchange of oxygen and carbon dioxide.
Describe the respiratory surface in land animals.
In land animals, the respiratory surface is internalized as linings of the lungs. Gas exchange occurs in millions of small air sacs known as alveoli in mammals and reptiles, and atria in birds.
How do the air sacs in the lungs facilitate gas exchange?
The air sacs in the lungs have a very rich blood supply, bringing the air into close contact with the blood, thus facilitating gas exchange.
What is the system of airways that communicate with the external environment?
The system of airways that communicate with the external environment consists of hollow tubes, the largest of which is the trachea, branching into the two main bronchi.
What are the differences in the air sacs between mammals, reptiles, and birds?
In mammals and reptiles, the air sacs are called alveoli, while in birds, they are known as atria.
What is the respiratory system?
The respiratory system is a biological system consisting of specific organs and structures used for gas exchange in animals and plants.
What are the respiratory surfaces internalized as in land animals?
In land animals, the respiratory surfaces are internalized as linings of the lungs.
What are the microscopic air sacs in the lungs called in mammals and reptiles?
In mammals and reptiles, the microscopic air sacs in the lungs are called alveoli.
What is the largest airway that communicates with the external environment?
The largest airway that communicates with the external environment is the trachea.
What do the air sacs in the lungs have a very rich supply of?
The air sacs in the lungs have a very rich blood supply, bringing the air into close contact with the blood.
