Croup, also known as laryngotracheobronchitis, isa type of respiratory infection that is usually caused by a virus.The infection leads to swelling inside the trachea, whichinterferes with normal breathing and produces the classic symptomsof "barking" cough, stridor, and a hoarsevoice..
Simply so, what are five conditions of the respiratory system?
Learn about all types of respiratory conditions,including the common cold, flu, pneumonia, asthma, cystic fibrosis,emphysema and chronic bronchitis.
Beside above, what is the mechanical act of taking air into the lungs? The process of taking air into the lungs iscalled inhalation or inspiration, and the process of breathing itout is called exhalation or expiration.
In respect to this, what is the act of breathing out?
The lungs bring oxygen into the body whenbreathing in and send carbon dioxide out of the bodywhen breathing out. Carbon dioxide is a waste gas producedby the cells of the body. The process of breathing in iscalled inhalation. The process of breathing out is calledexhalation.
What is a discoloration of the skin and mucous membranes caused by deoxygenation of the blood?
Cyanosis is defined as a bluish discoloration,especially of the skin and mucous membranes, due toexcessive concentration of deoxyhemoglobin in the blood causedby deoxygenation. Cyanosis is divided into two main types:central (around the core, lips, and tongue) and peripheral (onlythe extremities or fingers).

What is the most basic function of respiration?
The function of the respiratory system isto deliver air to the lungs. Oxygen in the air diffuses out of thelungs and into the blood, while carbon dioxide diffuses in theopposite direction, out of the blood and into thelungs.What will happen to a person whose respiratory system is not working properly?
Your body's organs, such as your heart and brain,need oxygen-rich blood to work well. Respiratoryfailure also can occur if your lungs can'tproperly remove carbon dioxide (a waste gas) from yourblood. Too much carbon dioxide in your blood can harm yourbody's organs.What organs are involved in the respiratory system?
Organs involved in respiratory system are: - Nose and nasal cavity.
- Pharynx.
- Larynx.
- Trachea.
- Bronchi.
- Lungs.
- Alveoli.
What is the structure of the respiratory system?
There are 3 major parts of the respiratorysystem: the airway, the lungs, and the muscles ofrespiration. The airway, which includes the nose, mouth,pharynx, larynx, trachea, bronchi, and bronchioles, carries airbetween the lungs and the body's exterior.What makes it hard to breathe when you have asthma?
Notice that the airways are narrowed (skinny), so lessair can move in and out of the lungs. When things areworking normally, the amount of air we breathe in is aboutthe same as the amount of air we breathe out. But during anasthma attack, air gets trapped inside the lungs making itharder and harder to breathe.What is an upper respiratory system?
The major passages and structures ofthe upper respiratory tract include the nose ornostrils, nasal cavity, mouth, throat (pharynx), and voicebox (larynx). The respiratory system is lined with a mucousmembrane that secretes mucus. The mucus traps smallerparticles like pollen or smoke.What separates the upper and lower airway?
The upper airways or upper respiratorytract includes the nose and nasal passages, paranasal sinuses, thepharynx, and the portion of the larynx above the vocal folds(cords). The lower airways or lower respiratory tractincludes the portion of the larynx below the vocal folds, trachea,bronchi and bronchioles.Is the thymus part of the respiratory system?
The thymus gland is the main organ of thelymphatic system. Located in the upper chest, this gland'sprimary function is to promote the development of cells of theimmune system called T lymphocytes.How does oxygen travel through the respiratory system?
Breathing starts at the nose and mouth. Youinhale air into your nose or mouth, and it travels down theback of your throat and into your windpipe, or trachea. Yourtrachea then divides into air passages called bronchial tubes.Here, oxygen from the inhaled air passes through thealveoli walls and into the blood.How does Boyle's law relate to breathing?
Boyle's Law describes the relationship betweenthe pressure (P) and the volume (V) of a gas. The law statesthat if the volume increases, then the pressure must decrease (orvice versa). When the volume of the lungs changes, the pressure ofthe air in the lungs changes in accordance with Boyle'sLaw.What is the airway from mouth to lungs called?
The trachea is a tube that carries the air in andout of your lungs. Each lung has a tube calleda bronchus that connects to the trachea. The trachea and bronchiairways form an upside-down “Y” in your chest.This “Y” is often called the bronchialtree.How does the human respiratory system work?
The primary organs of the respiratory system arethe lungs, which function to take in oxygen and expel carbondioxide as we breathe. The gas exchange process is performed by thelungs and respiratory system. Air, a mix of oxygen and othergases, is inhaled. In the throat, the trachea, or windpipe, filtersthe air.What is the name of the tiny air sacs in your lungs?
The smallest branches are called bronchioles andat the end of these are your air sacs (alveoli). Alveoli arefilled with air and look like bunches of grapes! They areabout 600 million alveoli in your lungs and they are allcovered with capillaries, which is where the oxygen gets intoyour blood!What is the function of the bronchi?
The bronchi, singularly known as a bronchus, areextensions of the windpipe that shuttle air to and from thelungs. Think of them as highways for gas exchange, withoxygen going to the lungs and carbon dioxide leaving thelungs through them. They are part of the conducting zone ofthe respiratory system.How do lungs clear themselves?
For several hours after the individual smoked, the tinyhairs called cilia that line the lungs slow down theirbrush-like movement. This causes them to become temporarilyparalyzed and less effective at cleaning out mucus and othersubstances, such as dust particles, from the airways.
