What is the function of the Alveoli in the respiratory system?

Gas exchange of oxygen and carbon dioxide takes place in the alveoli. Oxygen from the inhaled air diffuses through the walls of the alveoli and adjacent capillaries into the red blood cells. The oxygen is then carried by the blood to the body tissues.

What is the function of the respiratory system ?

A. To provide the body with oxygen and dispose of carbon dioxide


B. To provide the body with enzymes and hormones needed to function.


C. To provide the body with essential nutrients.


D. All of the above


E. None of the above

After being outdoors in the garden, you come indoors to find dirt in the mucus. What function of the respiratory system is your nose performing?

The nasal cavity is a hollow space within the nose and skull that is lined with hairs and mucus membrane. The function of the nasal cavity is to warm, moisturise, and filter air entering the body before it reaches the lungs. This is why you find dirt and other bacteria in the mucus membrane.

What is the formula for respiration?

C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + energy also know as glucose + oxygen → carbon dioxide + water + energy

What is the structure of the respiratory system?

The cells of the human body require a constant stream of oxygen to stay alive. The respiratory system provides oxygen to the body’s cells while removing carbon dioxide, a waste product that can be lethal if allowed to accumulate. There are 3 major parts of the respiratory system: the airway, the lungs, and the muscles of respiration. The airway, which includes the nose, mouth, pharynx, larynx, trachea, bronchi, and bronchioles, carries air between the lungs and the body’s exterior.

If someone smokes cigarettes for a long time, the alveoli will eventual be coated with tar. Why is this bad for the respiratory system?

Cigarette smoke is acidic and contains many different chemicals. As a result it can cause irritation of the lining of the bronchi and bronchioles. The lining becomes inflamed and swollen and may also become infected. Each time you smoke another it adds to the irritation, lasting for months and even years, causing shortness of breath, coughing and chest pain. This is known as chronic bronchitis.
