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.

What is the normal respiration rate for adults?
For adults it is only 12 breaths per minute when relaxed. Other older textbooks often say even smaller values (e.g., 8-10 breaths per minute). Most modern adults breathe much faster at about 15-20 breaths per minute
How do you resive oxygen and remove carbon dioxide?
Oxygen and carbon dioxide are moved to and from body tissues via the circulatory system. These materials diffuse through the cell membrane, and then diffuse through the capillary wall into or out of the bloodstream.
The medulla is one of the major brain centers affecting respiration true or false?
True: the medulla oblongata contains the primary respiratory center.
Respiratory sensors. Respiratory sensors monitor oxygen intake and carbon dioxide output.
How can a person's lifestyle affect the performance of the respiratory and circulatory systems?
Smoking, lack of exercise, lack of attention to asthma, and exposure to irritants such as dust can all affect the performance of the respiratory and circulatory systems.
The smooth muscle in the walls of the bronchioles is very sensitive to the concentration of carbon dioxide. A rising level of CO2 causes the bronchioles to dilate. This lowers the resistance in the airways and thus increases the flow of air in and out.
Starting with the nose name six respiratory organs in order of inhalation?
nose, arm, leg, head, and frog
Length of breath holding after hyperventilation?
after hiperventilation i can hold my breath much longer.it about three and half minutes
What is the relationship between alveoli and emphysema?
The alveoli are like plump grapes that are empty inside. They need the plump surface area for capillaries to wrap around them, so Red Blood Cells can trade oxygen molecules for carbon dioxide molecules. But in emphysema, the alveoli collapse. Surface area shrinks. The person cannot get good O2. The body starts to rely on increased CO2 (rather than low O2) to regulate when to breathe.
Mitochondria are organelles in which the biochemical processes of respiration and energy production occur. They act like a digestive system that takes in nutrients, breaks them down, and creates energy for the cell. They are known as the powerhouses of the cell.
What do the respiratory and the circulatory systems do together?
Working together, the respiratory and circulatory systems perform gas exchange from the blood to the lungs. This exchange occurs at the alveoli.
What factors determine a drug's rate of metabolism?
How quickly a drug clears from the body is a function of its absorption, bioavailability, distribution, metabolism, and excretion properties.
Where does tuberculosis occur in the respiratory system?
Most commonly in the lungs, but the tubercle bacillus can afflict many areas of the body. Anne Sullivan, the teacher of Helen Keller had a brother afflicted with a tubercular hip.
Does the diaphragm help with the removal of carbon dioxide in the respiratory system?
The respiratory system uses diffusion and the diaphragm to bring oxygen into the lungs and push carbon dioxide out of the lungs. When you breath in your diaphragm expands into a dome shape creating an area of decompression and the air is forced into your lungs filling the empty space. When breating out it is the opposite the diaphragm flattens and pushes the air out of the lungs. THe air mainly consists of carbon dioxide
Their vocal cords bend back while there esophogas breaths in and out.
How much nitrogen is inhaled and exhaled air?
The percentage inhaled is roughly 79% but it is only 74% when exhaled. The volume of Nitrogen does not change but the percentage out of all the exhaled gas decreases as there is far more CO2 and Water Vapour. Nitrogen itself not actually used up by the body, it is simply a byproduct of the nitrates and various emissions involved in photosynthesis from plants and various algae that get pumped with whimsical abandon into the atmosphere. Typical trees. Lest not forget the delicate equilibrium between humans and plants.
What are the short term effects of exercise on the muscular system?
redirection of blood flow to exercising tissue
What respiratory ailments does peppermint treat?
Peppermint is an expectorant and decongestant. It is used to help treat many respiratory ailments including asthma, bronchitis , sinusitis, and coughs.
Why ants yawn in human manner?
They don't. Ants have a completely different respiratory system to humans.
Besides your urinary system what other organs in your body help in excretion?
The respiratory system (lungs) allows the expulsion of gases and other wastes through respiration, the gastrointestinal system and intestines prepare and move the solid wastes, the liver filters toxins from the blood for excretion, much like the kidneys do to put wastes in the urinary system, the circulatory system (blood) moves the wastes from other parts of the body to the kidneys and liver to be prepared for excretion and the integumentary system (skin) excretes metabolic wastes in sweat and some chemical wastes can be also be excreted in tears.
