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.

Role of cilia in respiratory tract?
The cilia are very important in the respiratory tract.
Cilia are projections off cells called pseudostratified columnar cells. They are constantly moving back and forth, like blades of grass in the wind. Cilia act in conjunction as one big broom, sweeping particles trapped in the mucous up to the throat to be expelled like this *OBNOXIOUS SMOKER'S COUGH.*
How is anaerobic respiration used industrially and domestically?
One way this is used in industry to to make beer and for domestic use to make bread. Although both beer and bread making can be done both on a large scale (industry) or in a small scale (home).
Why do people die from compromised respiratory function?
A person with a compromised resipratory system is more suspectible to oppuntunistic pathogens such as Pseudomonas aeruginosa resulting in the development of an infection within the individual lungs. This infection damages the lungs resulting in less oxygen being absorbed, and if left untreated the infectio will spread and eventually cause death. if a person has a severely compromised respiratory system he/she would be unable to obtain enough oxygen to survive.

What instrument helps a doctor check the health of your respiratory system?
The most commonly-used instrument is a stethoscope.
How oxygen and carbon dioxide enters and leaves the body and is transported in the blood?
When you inhale, you take air into your lungs. There are structures within your lung called alveoli that are directly connected to the pulmonary (that is, 'of the lung') artery and vein. In these alveoli, oxygen is transferred into the blood in the artery (arteries carry oxygenated blood while veins carry deoxygenated blood). Red blood cells contain haemoglobin (American spelling 'hemoglobin'), an iron-based protein that carries the oxygen. As the blood travels through the body, oxygen is delivered to the tissues of the body in blood vessels called capillaries--extremely narrow vessels that branch off of the arteries (their tiny diameter assists in oxygen transfer)--in exchange for carbon dioxide. The capillaries then widen out again to become veins, and the blood--now carrying carbon dioxide--ultimately moves back to the lungs, where they are reloaded with oxygen and the carbon dioxide is released into the alveoli to be expunged from the body via exhalation.
Thank You Judy Olmsted! I really appreciate the answer.
What is the dome-shaped muscle under the thoracic cavity and what are its functions?
The dome-shaped muscle under the thoracic cavity is the diaphragm. Its function is to contract to increase the volume of the thoracic cavity, thereby decreasing pressure in the lungs and causing inspiration.
What warms and cleans air moving into the body?
The upper respiratory system cleans and warms the air even before going into the lungs. Tiny hairs in the upper tract remove particles which have become stuck in mucous made by the membranes. These same membranes warm and add moisture to the air before it reaches the alveoli.
Why can you see your breath on a cold mirror?
What happens here is the following: You have water vapor in your breath; when it cools down (as when it gets near the cold mirror), the air can hold less humidity (it becomes saturated), and some of the water condensates.
How do the organs of the respiratory system work?
Basically, the respiratory system works like transport system. As you breath oxygen is transported through the airways to the circulatory system. The circulatory system then delivers carbon dioxide back to the lungs to be breathed back out.
What comes first in the respiratory tree the respiratory bronchioles or the terminal bronchioles?
the terminal first
Do cattle and horses have diaphragms to assit in the respiratory system?
Yes, both cattle and horses have diaphragms to aid in respiration. All mammals have diaphragms and there isn't a mammal who can live without one.
How the larynx works in the throat while swallowing?
The larynx is located at the top of the trachea or windpipe. In the larynx, the vocal folds, commonly known as the vocal cords, close tightly when swallowing to prevent any food or drink from entering the trachea and lungs.
What does the body's respiratory system allow us to do?
It causes us to breathe. We could not live without the process it goes through for us.
Are people the only ones to breathe oxygen?
No, practically everything breaths oxygen besides non-living things
Is Homeostasis in respiration is controlled by the cerebrum?
It would mainly be parts of the midbrain and medulla
What are several non respiratory air movements?
theres crying, sneezing, coughing, laughing, hiccups, and yawn
What is the function of terminal bronchioles?
The bronchioles are divided into three types, each becoming progressively smaller. Terminal bronchioles are the second type and the final airways in the conduction zone. All bronchioles control the amount of air distributed through the lung by constricting and dilating.
One interesting fact about the respiratory system?
Our bodies only absorb 4% of the available 21% Oxygen in the air that we breathe in.
The surface area of the lungs is the same size as a tennis court !
How does respiratory system help the body maintain homeostasis?
The respiratory system is the group of tissues and organs in the body that enables the body to breathe. This system includes airways, lungs and the blood vessels and muscles attached to them that work together so the body can breathe. The respiratory system's primary function is to supply oxygen to all the parts of the body.
