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.
Asked in Respiratory System
What are the functions of the respiratory system?
The main function of the respiratory system is to discard waste in the form of carbon dioxide and to take in oxygen. Carbon dioxide is carried to the lungs in erythrocytes (red blood cells) and released, then the erythrocytes collect oxygen and deliver this essential gas to our bodies. The mucus in the respiratory system helps to protect it as well as to carry debris out of the respiratory tract, which is assisted by the movements of little hair-like structures called cilia....
What is the medical term meaning voicebox?
The proper name for the voice box is the larynx and it connects the pharynx to the trachea. Pitch and volume are controlled here by manipulating the vocal chords, you wouldn't be able to speak without one. The voicebox is also known as the larynx, across which the vocal cords -- the structures responsible for sound production during phonation -- are stretched. ...
What is the role of pons and medulla oblangata in regulating the cardiovascular and respiratory systems and how is it effected by exercise?
The pons and medulla oblongata are part of the central nervous syst. (CNS) During times of physical or emotional stress, the autonomic nevous syst.(ANS) stimulate the sinoatrial node (SA) and the atrioventricular node (AV) and the cardiac muscle itself. When the demand declines the heart adjusts, the parasympathetic nerves slow and steady the heart. For breathing: Neural centers that control respiratory rhythm and depth are located mainly in the medulla and pons. the medulla sets the basic rhythm of breathin, it contains a pacemaker...

How do you take care of your respiratory system?
Our lungs are precious, and the most important part of our respiratory system. These organs are responsible for absorbing and distributing all the oxygen that our body needs in order to function normally. Fitness: It is important to keep your lungs fit. Regular physical activity is the only consistent way to ensure the fitness of your respiratory system. The more you use your lungs and diaphragm, the more fit they will - just like any other muscle in your body. Protection: The more careful...

What is the speed of the average sneeze?
An average sneeze comes from your mouth and nose at somewhere between 40 and 100 mph. There can be variation: This was tested on MythBusters and they found their fastest sneeze being 39 mph. Not to say some people don't sneeze faster, but 102 mph is the fastest recorded speed. The world record has been said to be at 115 km per hour [71.5 mph]. The average person can sneeze as fast as up to 700mph. 100 MPH. ...
Asked in Respiratory System
What structure in the airway prevents food and liquid from entering the lungs?
The epiglottis is a leaf-shaped, flap-like structure made of elastic cartilage that covers the trachea like a lid. The epiglottis directs food to the stomach (through the esophagus) and air to the lungs (through the trachea). When you swallow, your epiglottis closes off your larynx leaving the only open passage the esophagus. This is why we cannot breathe and swallow at the same time. If people do not have good dental hygiene they leave small particles of food which they leave in their...

Food plus oxygen gas - Carbon dioxide plus water plus cellular energy what cellular process is represented?
This process is aerobic respiration which is written in words instead of an equation . ...

Why is hard to breathe in summer?
There can be numerous reasons why it may be more difficult to breathe in the summer, some are, seasonal allergies, ozone, poor air quality, humidity, pollen, open windows leaving in car exhaust fumes and other air pollutents. Cheyzer ...
Asked in Respiratory System
How do the lungs perform their function?
A muscle below your lungs, called your diaphram, contracts, letting air in your air sacs within your lungs, and relaxes, pushing carbon dioxide out. The oxygen is then used to replenish the life of your blood cells, by your heart taking oxygen and giving carbon dioxide from your blood cells. ...

What are the three characteristics of respiration?
1: Aerobic (with oxygen) or anaerobic (without oxygen) 2: GLucose + oxygen -> Water + Carbon dioxide + Energy 3: iT is a form of combustion ...
Asked in Digestive System, Respiratory System
How do symbiotic interactions impact digestion?
There are symbiotic relationships between animals and bacteria in the digestive area. The animals give the bacteria a place to live and the bacteria help break down food. Digestion would be a lot more difficult without these symbiotic relationships. ...

Trace the route of air from the nares to an alveolus?
During breathing air enters the nose by passing through the external nares( nostrils)=> pharynx=>larynx=> trachea=> The trachea (windpipe) divides into two main bronchi (also mainstem bronchi), the left main bronchus and right main bronchus. The right main bronchus subdivides into three lobar bronchi while the left main bronchus divides into two. The lobar bronchi divide into => tertiary bronchi, also known as segmental bronchi, each of which supplies a => bronchopulmonary segment. A bronchopulmonary segment is a division of a lung that is...

What are symptoms of respiratory acidosis?
The primary symptom would be increased respirations as the body attempts to clear the acidosis, to increase base pH. Respiratory acidosis can become so severe the person is short of breath (SOB). But typically the patient needs fluid replacement to restore homeostasis--the lungs cannot clear acidosis by themselves-- and possibly external O2 administration. With fluid replacement, by IV opened wide (and potentially several IV bags of 1,000 ccs each administered over a few hours), the kidneys will be supported to clear the acidosis....
Can you breathe through your eyes?
The corneas, the clear outer coverings through which light passes to the rest of the eye, have no blood vessels and get their oxygen directly from the atmosphere. In this sense, you "breathe" through your eyes. However, the amount of oxygen gotten this way can't keep much more than the corneas of the eye alive. The inside corner of each eye also has a small tube running to the nose to drain excess tear fluid from the eyes. When you cry, the...
