The air first enters into the nasal cavity (or mouth) then to the pharynx. Air is warmed by the nasal passages. From there, it passes through the trachea, then to the main bronchi (2, plural is bronchi; 1 is bronchus), and begins its descent into numerous bronchioles in the lungs. Within the lungs, the structures look like an upside down tree, wider at the top (the bronchi, which is like a split trunk of a tree), and getting increasingly narrower in the bronchioles (similar to branches on a tree being wider then getting narrower as the branches reach upward on a tree). At the ends of each bronchiole, there are clumps of aveoli which look like a clump of grapes. The aveloi round balls (just one is an aveolus) have a thin membrane which has many small blood vessels over and around each one. Here, the air we breathe passes into the bloodstream as oxygen. At the same time, carbon dioxide is released from the bloodstream to the aveloi, which expel it into the bronchioles, up though the lungs to the main bronchi, up the trachea, and back up to and out either the nose or the mouth.

∙ 14y agoThe lungs, airways, diaphragm, windpipe, throat, mouth and nasal passages are all part of the respiratory system. Respiration is the process of breathing in and out through this system. Oxygen is taken into the body through the airways absorbed into the lungs, then transported through the body in the blood or bloodstream. The lungs also give out carbon dioxide into the atmosphere.

What system is the pharynx larynx and trachea a part of?
The pharynx is the part of the throat through which both air and food pass, this means that is it part of both the respiratory and digestive system.
Molecules can pass through the cell membrane of the human cell?
The molecules that can pass through the cell membrane of the human cell include water. Other molecules include fat soluble vitamins.
Which system of the body is known as the breathing system?
The the respiratory system or "breathing system" has many different functions. The main function that the body relies on is to supply the body and organs with Oxygen with Inhalation and Exhalation. Two other things we rely on the respiratory system for is vocalization or speech, and coughing. To be able to speak air must pass from the lungs over the vocal cords. Coughing allows the body to expel foreign objects like virus' keeping the body safe and healthy.
Why do nutrients need to be broken down before they can be absorbed by the human body?
So that it can be small enough to pass through a cell's membrane.
What is the passage through which food and air both pass though?
pharynx
What dose the respiratory system do?
the respiratory system allows exchange of gases in order for oxygen to becirculated throughout the body and carbon dioxide given out

In frogs what is the path of food through the respiratory system?
In no animal does food pass thought the respiratory system. The respiratory system is used for breathing (gas exchange) not food. The Alimentary Canal or gastrointestinal tract is what is employed for the digestion of food.
Why are those who have had skull fractures vulnerable to meningitis?
Organisms that usually live in the human respiratory system without causing disease can pass through openings caused by such fractures, reach the meninges, and cause infection.
What system is the pharynx larynx and trachea a part of?
The pharynx is the part of the throat through which both air and food pass, this means that is it part of both the respiratory and digestive system.
Is it true that the respiratory system benefits from the digestive system?
RESPIRATORY SYSTEM is the process of respiration. The lungs is the main organ of the respiratory system because it receives oxygen and take out the carbon dioxide. DIGESTIVE SYSTEM is the process of digestion. The main organ is the stomach because this is where the digestion occurs.
Is the pharynx part of the immune system?
no, it is part of both the respiratory and digestive system, it is the passage through which both air and food pass before separating into the esophagus for food or the trachea for air
How are the respiratory and the digestive systems similar?
The cardiovascular system consists of the heart, veins and arteries. Which are all part of the network which moves blood around your body. Your respiratory system is your lungs and airways. This system is responsible for gas exchange (taking in oxygen and expelling CO2). They work hand in hand, your respiratory system takes in oxygen and passes it into your cardiovascular system, which transports it to all of your muscles and organs. The muscles and organs pass back CO2 which is then expelled through your respiratory system.
What are Vitamins that pass through the system easily are called what?
What are vitamins that pass through the system easily called?
Compare and contrast the role of the villi in the digestive system with the role of the alveoli in the respiratory system?
they are very similar, both have: thin walls through which particles can pass consist of tiny projections occurs in huge numbers
How can the respiratory system put oxygen into the blood and carbon dioxide out of the blood?
Oxygen and carbon dioxide are both gases, which makes them easier to pass through the cell. In addition, the site of trading the respiratory gases occur at alveoli, which has capillaries attached to it. The membranes in these regions are each one cell thick, which enables the respiratory gases to pass through easier. When the blood reaches the lungs, simple diffusions then take the carbon dioxide out of the cell and oxygenates the blood.
Which part of the respiratory system does air pass over to give rise to your sense of smell?
Nasal Cavity
