Respiratory System
The respiratory system includes the lungs and the airway. The questions in this category focus mainly on the anatomical and physiological processes associated with breathing.

Why is carbon dioxide released when you breath?
its called photosynthesis trees let out oxygen and you breathe it in then you breathe out carbon dioxide which the trees breathe in. So basically its from the oxygen the trees breathe out
What happens when the diaphragm is punctured?
Diaphragmatic injury are most commonly seen after chest injuries and road traffic accidents. A small puncture wound can cause problems with bleeding and haemothorax, but large defects causes the abdominal organs to go up the chest compromising breathing and will require emergency Surgery.
What are the organs in your respiratory system?
The organs that make up the respiratory system are the lungs ,trachea ,bronchial tubes,mouth,nose( anything you use to breath.)IDK i think this is right i studied it for a while til i dropped out.
We got the nasal passage, oral cavity, pharynx, larynx, trachea, bronchi, lung, heart, and the ribs.
Why is the trachea reinforced with cartilaginous rings?
The 'c' shaped cartilage rings are present in the trachea to prevent it from collapsing and they keep the trachea open for air to come in and out. In humans there are about 15 - 20 incomplete C-shaped cartilaginous rings which reinforces the anterior and lateral sides of the trachea to protect and maintain the airway open. (The cartilaginous rings are incomplete because this allows the trachea to collapse slightly to allow food to pass down the esophagus
to give support
The rings of cartilage strengthen the trachea so that it does not collapse, but remains open so that air can get through it.
If It didn't it would collapse in on itself and you would be unable to breathe.
we breath every time so trachea keep open all the time .cartilage rings give support to trachea to open all the time.
The cartilage rings in the trachea keep it from collapsing upon itself with the negative pressure inside of it during inhalation.
The Trachea (also known as the wind pipe) has cartilage rings on it. This prevents the pipe collapsing on itself. If the trachea did collapse, it would disallow us from breathing. Also the trachea might collapse and damage the esophagus (also known as the food pipe) which is behind it.
I'm in Year 8 (or Grade 8 in the (U.S)) and i know that. ;P
It stops it from collapsing when bending the neck, and protects it from tears and other damage.
The trachea (windpipe) has cartilage in it so that it won't collapse when you move your head.
Does horse riding involve aerobic or anaerobic respiration?
its actually an anaerobic sport mainly working your leg muscles and core
Why must all respiratory system have a large surface area over which air can pass?
You have barile?
Lungs have hierarchical structure which minimizes volume but maximises surface area
Aveoli are the smallest units of structure and are the site of gaseous exchange:
- They are circular = max surface area for min volume
- Their most surfaces faciliate the exchange of gases
- They have extensive blood supply which also faciliate the exchange
What process is responsible for movement in gases inside the lungs?
the diaphragm tightens (moves down) expanding the lungs. This expansion creates the pressure in the lungs to decrease. Since nature always strives for equilibrium, high pressure moves to low pressure areas --> air fills the lungs. the diaphragm relaxes, moving back up in the chest cavity, increasing the pressure on the contents in the lungs. The air escapes the lungs to reach the lower pressure area outside our body.
What are 3 disorders of the respiratory system?
The respiratory system has two parts, the upper and the lower. Common conditions of the upper respiratory system include, hay fever and rhinitis. Lower respiratory ailments include asthma, bronchitis, pneumonia, emphysema, and tuberculosis.
What is the most important thing you can do to protect your respiratory system?
The most important decision is not to start smoking.
What is the main origin of the respiratory system?
The trachea is the main trunk of the respiratory system. It is the central passageway from which the respiratory tree branches.
What part of the respiratory system is the substance produced by the lining of the nasal cavity?
Mucus is a substance produced by the lining of the nasal cavity. This mucus helps moisten and filter incoming air.
What happens during a sympathetic activation of the respiratory system?
Sympathetic activation almost always speeds up any system. In this case breathing rate.
What is the order of the respiratory system?
I'm not sure I understand the question- if you want a list of respiratory diseases for an assignment for your science class, here are a few: Asthma Pulmonary Disease (something smokers get) Croup (something children get) Common cold bronchitis Hope that helps! Heather (an MD from Canada)
How is the heart related to respiratory system?
The main part is the nerves the nerves tell your body to move.
What are the the three things that occur in the respiratory system as a person ages?
Functional Consequences of Age-Related Changes Affecting Respiratory Function
- Upper airway changes: calcification of cartilage, altered neuromuscular function and reflexes.
- Increased anteroposterior diameter, chest wall stiffness, weakened muscles and diaphragm.
- Enlargement of the alveoli, thinning of alveolar walls, diminished number of capillaries.
Decreased elastic recoil and early airway closure.
- Tidal volume unchanged or slightly diminished, increased residual volume, decreased vital capacity.
When you inspire to take a breath what happens to the pressure and volume in the lungs?
When the diaphragm contracts the lungs are pulled down. This creates space in the lungs for air to rush in because air pressure is greater outside the body than inside the body. So in order to reach an equilibrium the air outside rushes into the lungs when you inhale.
To my little knowledge of the body,the lungs collapse on exhaling and expand on inhaling.As the brain controls everything,except the heart, the heart has cells which can think for itself.If the brain stopped functioning,the heart can still beat as long as it has oxygen in the lungs.As soon as the air is used up the heart will eventually stop.When you sleep your heart keeps the lungs inhaling and exhaling to maintain life until you awake.Then the brain goes into a rest period and just gives the heart and lungs a slight electric shock to keep them going. If Im wrong here please let me know.
The importance of the cardiovascular and respiratory systems working and functioning together correctly is to keep you alive.
Respiratory takes in oxygen and expels CO2
Cardiovascular transports both around your body
In the upper respiratory tract, you have ciliated cells and mucosal glands that help keep particles out of the lower respiratory tract. Where the very thin type 1 cells faciliate gas exchange.
What is the function of the respiratory system system?
The respitory system (sinus, treakea, lungs) fills brings air to a place where oxygen in the air can be transferred to the blood which then carries it throughout the body. The respiratory system also removes carbon dioxide, a cellular waste product, from the body.
What is the respiratory organ of a man?
The respiratory organs of man are called the lungs. The lungs are located in the chest and are protected by the rib cage.
How is air warmed and moistened as it passes through the nasal cavity?
The inhaled air 'swirls' around the conchae
moistens via the mucus secreted by the goblet cells and drainage from the nasolacrimal ducts; cleans by the mucus trapping dust particles and the cilia moving the mucus and trapped dust particles toward the pharynx
