What is the define of breathing?
Breathing: The process of respiration, during which air is inhaled into the lungs through the mouth or nose due to muscle contraction and then exhaled due to muscle relaxation..
What is the pathway of airflow?
Pathway of air: nasal cavities (or oral cavity) > pharynx > trachea > primary bronchi (right & left) > secondary bronchi > tertiary bronchi > bronchioles > alveoli (site of gas exchange)
Why does food not go into lungs?
The air then goes down into your main airway (trachea) and into your lungs. A flap of tissue called the epiglottis sits over the top of the trachea. This flap blocks food and drink from going down into the trachea when you swallow. But in some cases, food or drink can enter the trachea causing aspiration.
Which of the following list the structures in the correct order of airflow?
Place in the correct order the structures which inhaled air passes through on the way to the blood stream: alveoli, nasal cavity, larynx, pharynx, bronchi, trachea, alveolar duct.
What is the correct sequence for the path of airflow when you inhale?
This process takes place 12 to 20 times per minute. When you inhale through your nose or mouth, air travels down the pharynx (back of the throat), passes through your larynx (voice box) and into your trachea (windpipe). Your trachea is divided into 2 air passages called bronchial tubes.
How do you describe the pathway of oxygen in the breathing?
Respiration begins at the nose or mouth, where oxygenated air is brought in before moving down the pharynx, larynx, and the trachea. The trachea branches into two bronchi, each leading into a lung. Each bronchus divides into smaller bronchi, and again into even smaller tubes called bronchioles.
What important activity takes place in the lungs?
The main function of the lungs is the process of gas exchange called respiration (or breathing). In respiration, oxygen from incoming air enters the blood, and carbon dioxide, a waste gas from the metabolism, leaves the blood.
What is the pathway for both food and air?
The pharynx is part of the digestive system as well as the respiratory system because it carries both food and air. At the bottom of the pharynx, this pathway divides in two, one for food — the esophagus (ih-SAH-fuh-gus), which leads to the stomach — and the other for air.
What is the order of structures that oxygen passes through?
Air then travels down the pharynx and larynx, through the trachea, and into the lungs. In the lungs, air passes through the branching bronchi, reaching the respiratory bronchioles. The respiratory bronchioles open up into the alveolar ducts, alveolar sacs, and alveoli.
What is difference between breathing and swallowing?
In breathing, air may flow through either the nose or the mouth, it always flows through the pharynx. During swallowing, the pharynx changes from an airway to a food channel.
How does air enter and exit the body?
Air enters your body through your nose or mouth. Air then travels down the throat through the larynx and trachea. Air goes into the lungs through tubes called main-stem bronchi.
Which correctly orders the steps of the path of air through the lungs?
Terms in this set (7) Air rushes in through the nose and mouth and passes through the throat. Air then moves past the epiglottis which is open into the trachea. Air moves into your bronchi. The bronchi branch out and end in tiny air sacs, called alveoli.
What is the correct order of the passage of air through the respiratory system?
Air enters the respiratory system through the nose and mouth and passes down the throat (pharynx) and through the voice box, or larynx.
What is the pathway of oxygen?
During gas exchange oxygen moves from the lungs to the bloodstream. At the same time carbon dioxide passes from the blood to the lungs. This happens in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.
