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.
2,890 Questions
Are the esophagus and trachea connected?
NO. Windpipe is the Larynx and pharynx, and the esophagus is the tube to the stomach. The airway is closed off by a flap of skin, as you swallow, to prevent food or drink from getting into the "windpipe". If you have ever been strangled on something you swallowed, you know what happens when the latter is a little slow to cover the opening.
What types of cells are affected by Swine Flu?
The major cells affected by influenza viruses, including swine flu H1N1/09, are those in the respiratory system mucous tissues.
What is the changes in size of thoracic cavity during the contraction and relaxation of diaphragm?
When the Diaphragm contracts, it is pulled down, and is pulled back up when it relaxes.
Also, when you inhale, it contracts. When you exhale, it relaxes.
Where are the gases that make up the solution we breathe separated?
- An air separation plant separates atmospheric air into its primary components, typically nitrogen and oxygen, and sometimes also argon and other rare inert gases.
- The most common method for air separation is cryogenic distillation. Cryogenic air separation units (ASUs) are built to provide nitrogen or oxygen and often co-produce argon.
- Other methods such as Membrane, pressure swing adsorption (PSA) and Vacuum Pressure Swing Adsorption (VPSA), are commercially used to separate a single component from ordinary air.

What is the purpose of oxygen in the body?
A. It picks up electrons and hydrogen ions from the electron transport chain to form water
B. It aids in the breakdown of glucose
C. It participates in the chemiosmotic gradient in the electron transport chain
D. It is part of coenzyme A
What holds the breathing tubes to the lungs open?
The larynx or voice box provides a passage. but the alveoli help
What role does oxygen and carbon dioxide play in the circulatory system?
The lungs use oxygen and carbon dioxide through cellular respiration.
Which two places does respiration take place?
A single diode acts as a half wave rectifier. That is half of the wave is cut off as the current reverses. You will see just the top half of the sine wave on a diagram.
Adding a second diode in series in theory will cut off the bottom half of the wave so giving a flat line - but in fact the two diodes have actually cut off all the current so nothing flows. Two ddiodes in paralle' won't work either as current will flow in either depending on the sirection of flow.
To get true full wave rectification a diode bridge consisting of 4 diodes should be used.
What are you doing when your diaphragm moves up and your ribs move down and in?
Your diaphragm lowers and your ribs expand outwards
What is the breathing process?
Breathing consists of two phases, inspiration and expiration.
- During inspiration, the diaphragm and the intercostal muscles contract. The diaphragm moves downwards increasing the volume of the thoracic (chest) cavity, and the intercostal muscles pull the ribs up expanding the rib cage and further increasing this volume. This increase of volume lowers the air pressure in the alveoli to below atmospheric pressure. Because air always flows from a region of high pressure to a region of lower pressure, it rushes in through the respiratory tract and into the alveoli. This is called negative pressure breathing, changing the pressure inside the lungs relative to the pressure of the outside atmosphere.
- In contrast to inspiration, during expiration the diaphragm and intercostal muscles relax. This returns the thoracic cavity to it's original volume, increasing the air pressure in the lungs, and forcing the air out.
Is the windpipe and trachea are different parts of the respiratory system?
No trachea is the medical name for the windpipe which leads down to the bronchi eventually to the blood through the lungs.
What type of circulatory system does a jellyfish have?
A jellyfish does not have any circulatory vessels. They use diffusion as their means of circulation. They do not have a closed circulatory system.
What structures are considered part of the upper respiratory tract?
The parts of Upper Respiratory are:
nasal cavity (either of the two cavities lying between the floor of the cranium and the roof of the mouth and extending from the face to the pharynx)
larynx (a cartilaginous structure at the top of the trachea; contains elastic vocal cords that are the source of the vocal tone in speech)
trachea (membranous tube with cartilaginous rings that conveys inhaled air from the larynx to the bronchi)
pharynx (the passage to the stomach and lungs; in the front part of the neck below the chin and above the collarbone)
olfactory organ (the organ of smell and entrance to the respiratory tract; the prominent part of the face of man or other mammals)
What composes the respiratory system?
The lungs, alveoli, diaphragm, nasal cavity, trachea, intercoastal muscle, bronchi, oesophagus.
How has the mountain goats respiratory system adapted permantly to different altitudes?
The mountain goats respiratory system is adapted permanently to different altitudes. This is because it is the cellular respiratory system which allows it to survive the low oxygen climate.
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 some threats to the respiratory system?
Some known threats to the immune system are:Asthma, Pollution, Cancer, and multiple other things so keep your lungs healthy and don't try breathing when drinking or eating because the food or liquid will go into your lungs and possibly damage them.
What is normal respiratory movement?

Normal respiratory movements include rib cage expansion, diaphragm contraction and downward movement, abdominal contractions, lung expansion, opening of veins and arteries in chest, heart rate increase during inhalation and increase of thoracic cavity
What is the medical term meaning the amount of air that can be inspired above the tidal volume?
Inspiratory reserve volume is the volume you can inhale past the normal tidal volume.
What tissue is the walls of the alveoli composed of?
the walls of the alveoli are very thin but strong layers of elastic tissue lines with a single layer of flattened epithelium.
How emphysema reduce the efficiency of gas exchange in the lungs?
Emphysema and asthma both cause fluid buildup in the lungs and airways causing the body to work harder in order to provide oxygen to the body and to release carbon dioxide from the body. Asthma can also cause airway inflammation.
Is gullet a respiratory system?
The gullet is part of the digestive system. The gullet is also called the esophagus.
What are the signs and symptoms for ailments of the circulatory system?
Shortness of breath, pain in the left chest, left arm pain.
