Air enters the body through the nose or mouth, passes through the pharynx, larynx, trachea, bronchi, and bronchioles, and finally reaches the alveoli in the lungs where gas exchange occurs. During exhalation, the air follows the same pathway in reverse to exit the body.

Largest tube of the respiratory tract?
The trachea, also known as the windpipe, is the largest tube in the respiratory tract. It carries air from the larynx to the bronchi and is essential for the passage of air into the lungs for respiration.
The diaphragm contracts during what phase of respiration?
The diaphragm contracts during the inhalation phase of respiration. When it contracts, it moves downward, increasing the volume of the thoracic cavity and causing air to rush into the lungs.
What Organ takes Oxygen out of the air for respiration?
The lungs take in oxygen from the air during respiration. Oxygen is absorbed into the bloodstream through tiny air sacs called alveoli in the lungs, where it is then transported to cells throughout the body.
Does cellular respiration remove cardon dioxide from the air?
No, cellular respiration actually releases carbon dioxide into the air as a byproduct of breaking down glucose to produce energy in the form of ATP. Plants, on the other hand, remove carbon dioxide from the air during photosynthesis.
What does the diaphragm do during respiration?
The diaphragm contracts during inhalation, allowing the lungs to expand and fill with air. This helps to create negative pressure in the chest cavity, drawing air into the lungs. During exhalation, the diaphragm relaxes and moves back up, helping to push air out of the lungs.
What are the functions of bronchi and bronchioli?
They just function as air passage and carry the air in and out of the lungs during respiration
What has cartilage rings to prevent collapse during respiration?
Tracheal cartilage rings provide support and prevent collapse of the trachea during respiration. They are C-shaped structures made of hyaline cartilage that keep the trachea open to maintain a patent airway for the passage of air in and out of the lungs.
What happens during the first stage of respiration?
you obsorve air
What substance is brought into the body during respiration?
Air is brought into the body during respiration, and oxygen is absorbed by the hemoglobin of the red blood cells in the lungs by diffusion. Carbon dioxide is removed during respiration -- without the removal of the CO2, the oxygen wouldn't get in.
How do the processess of photosynthesis and cellular respiration work together?
both of which are released into the air during respiration. And during respiration, the plant needs oxygen and glucose, which are both produced through photosynthesis!
What is the correct order of the passage of oxygen during the first phase of the respiration cycle?
During the first phase of the respiration cycle, oxygen enters the body through the nose or mouth, passes through the pharynx and larynx, and then travels down the trachea into the lungs. Once in the lungs, oxygen crosses the alveolar membrane and enters the bloodstream where it binds to hemoglobin in red blood cells for transport to tissues throughout the body.
What do all living creatures inhale during respiration?
They inhale air. What they extract from the air is oxygen.
What substance is removed from the air by living things for respiration?
Living things remove oxygen from the air during respiration. Oxygen is taken in by organisms to produce energy through a process called cellular respiration.
What is the function of surfactant?
prevent each alveolus from collapsing as air moves in and out during respiration
Is an alveoli an air sac or an air passage?
Alveoli is an air passage
Largest tube of the respiratory tract?
The trachea, also known as the windpipe, is the largest tube in the respiratory tract. It carries air from the larynx to the bronchi and is essential for the passage of air into the lungs for respiration.
How is oxygen taken from the air?
Oxygen is taken from the air through a process called respiration. During respiration, humans and animals inhale air containing oxygen, which is then transported to the lungs where it is absorbed into the bloodstream and delivered to cells in the body for energy production.
