What else can I help you with?
List the organs air will travel through as you breathe in order?
Nares, nasal cavity, pharynx, larynx, trachea, bronchus, bronchioles, alveoli
How does surfactant affect the total air flow into lungs?
Surfactant is similar to a detergent, it keeps the fluid coating the lining of the alveoli from creating surface tension. This allows the alveoli to expand without hindrance, and allows greater air flow.
How does air flow between neighboring alveoli?
You use the respirerotry system. To be precise when air is to be sucked in, the brain askes the lungs to expand, which naturally creates a low pressure inside the lungs. Similarly when the lungs are compressed the air inside is flushed out.
What tiny cubes contain smooth muscle that can contract and relax thereby affecting the flow of air into the alveoli?
You do not have any such cubes in your respiratory system.
What goes in and out of the external nares?
Air moves in and out of the external nares, also known as the nostrils. During inhalation, air enters the respiratory system through the external nares, where it is filtered, humidified, and warmed before reaching the lungs. During exhalation, air exits the respiratory system through the same external nares.
Is an alveoli an air sac or an air passage?
Alveoli is an air passage
What are the air sacs in your lungs?
Alveoli alveoli - air sacs in your lungs
Do capillaries surround alveoli?
The alveoli are the sites of respiration: the oxygen in them provided by the inhaled air diffuses into the blood cells that flow through the capillaries. Carbon dioxide diffuses out of the blood and into the alveoli so it can be exhaled. The capillaries provide a way for the blood to reach the alveoli. Hope this helps
What is the functional unit of lungs?
alveoli
According to if it were not for pulmonary surfactants you should expect the surface tension in a small alveolus to produce greater pressure than in a large one and air would flow from small to large?
Pulmonary surfactants reduce surface tension in alveoli, preventing them from collapsing and making it easier for air to flow in and out of the lungs. Without surfactants, smaller alveoli would have a higher surface tension, leading to greater pressure inside them compared to larger alveoli. As a result, air would tend to flow from smaller alveoli to larger ones to equalize pressure, potentially causing problems with lung function.
What is the correct sequence of air flow through the respiratory system and which is powered by what?
Pharynx, larynx, trachea, bronchi, alveoli; diaphragm
What are the tiny air sacs called in the bronchi branches?
Alveoli
