What is the basic rhythm of breathing is controlled by?
The basic rhythm of breathing is controlled by part of the brain called the Medulla.
How does coughing effect the respiratory system?
Emphysema is a long-term, progressive disease of the lungs that primarily causes shortness of breath due to over-inflation of the alveoli. In people with emphysema, the lung tissue involved in exchange of gases is impaired or destroyed. Emphysema is included in a group of diseases called chronic obstructive pulmonary disease or COPD. Emphysema is called an obstructive lung disease because airflow on exhalation is slowed or stopped because over-inflated alveoli do not exchange gases when a person breaths due to little or no movement of gases out of the alveoli.
Emphysema changes the anatomy of the lung in several important ways. This is due to in part to the destruction of lung tissue around smaller airways. This tissue normally holds bronchioles open allowing air to leave the lungs on exhalation. When this tissue is damaged, these airways collapse, making it difficult for the lungs to empty and the air becomes trapped in the alveoli.
Respiratory passageways narrowed by bronchiolar spasms?
Asthma: spasms and narrowing of bronchi leading to airway obstruction
What gas does the respiratory system get rid of?
The respiratory system utilises oxygen from the environmrntal gases and expires carbon dioxide (CO2).
What does the respiratory system do for other systems?
The respiratory system helps the circulatory system.

What is an abnormal respiratory sound heard on an auscultation?
An abnormal respiratory sound heard on auscultation could be an indication of fluid in the lungs and reduced airflow to the part of the lungs. Abnormal respiratory sounds may come in the form of rales, rhonchi, stridor, or wheezing.

How does the respiratory system meet human needs?
The Respiratory system help us meets its needs by giving us energy
Why smoking is harmful to the respiratory system?
Smoking isn't good for your body. It gives you bad breath, wrinkles, makes you smell bad, affects how well you can play sports because you can't run as far or fast, stains your teeth, roughens your skin, and it mixes up the fluids in your brain so you can't think right. It also causes heart disease, emphysema, lung cancer, throat cancer, and mouth cancer. If people didn't start they wouldn't get hooked on it! I don't think that they should be produced.
What does the respiratory system allow us to do?
When we breathe from our mouth or nose, the air, which contains oxygen, nitrogen, and other types of gases, pass the larynx, where the vocal cords locate. When oxygen reaches the chest cavity, the bronchi divides itself so that the bronchi can direct the oxygen to the lungs. When the bronchial tubes direct the oxygen and air into the alveoli, it then reaches your bloodstream. When the respiratory system finishes its course, the diaphragm, which locates under the chest cavity, eliminates carbon dioxide. This explains why we have to exhale after we inhale.
The main purpose of the respiratory system is to supply oxygen for the blood and other organs such as the brain.
What is the main excretory organ in a fetal pig?
The main excretory organ in a fetal pig are the kidneys. The kidneys are responsible for maintaining water levels and excreting waste matter from the blood.
How do the immune and respiratory systems work together?
Every life form needs oxygen. First of all, The respiratory system is connected with the cardiovascular system where blood gets oxygenated. As well all know, the blood is composed of several cells such as the red blood cells, white blood cells, platelets. The white blood cells are responsible for immune responses in the body. Without oxygen, all three would not function well and would make the person very ill and prone to infection.
How does the heart work with the respiratory system?
The heart pumps deoxygenated blood to the lungs, where capillaries at the air sacs exchange carbon dioxide for oxygen. Then the heart pumps that blood to the body tissues.
Is upper respiratory infection contagious?
Yes, it is contagious. It is spread easiest between children but adults can get it also. It is most contagious within the first 2 to 4 days when symptoms first appear. However, it may remain contagious up to 3 weeks. Be sure to wash your hands immediately after coughing and/or sneezing to avoid spreading the virus to others. Try to avoid large crowds when contagious. Doctors now recommend getting alot of rest, increase fluids, and treat symptoms as needed with over the counter medications (Tylenol, Motrin, Robitusin, etc.).
Insects require oxygen just as we do, and must "exhale" carbon dioxide, a waste product of cellular respiration. Oxygen is delivered to the cells directly through respiration, and not carried by blood as in vertebrates.
Along the sides of the thorax and abdomen, a row of small openings called spiracles (8) allow the intake of oxygen from the air. Most insects have one pair of spiracles per body segment. Small flaps or valves keep the spiracle closed until there is a need for oxygen uptake and carbon dioxide discharge. When the muscles controlling the valves relax, the valves open and the insect takes a breath.
Once entering through the spiracle, oxygen travels through the tracheal trunk (8), which divides into smaller tracheal tubes. The tubes continue to divide, creating a branching network that reaches each cell in the body. Carbon dioxide released from the cell follows the same pathway back to the spiracles and out of the body.
Most of the tracheal tubes are reinforced by taenidia, ridges that run spirally around the tubes to keep them from collapsing. In some areas, however, there are no taenidia, and the tube functions as an air sac capable of storing air.
In aquatic insects, the air sacs enable them to "hold their breath" while under water. They simply store air until they surface again. Insects in dry climates may also store air and keep their spiracles closed, to prevent water in their bodies from evaporating. Some insects forcefully blow air from the air sacs and out the spiracles when threatened, making a noise loud enough to startle a potential predator or curious person.
What are the respiratory organs of a crayfish?
Crayfish breathe using gills, which are located between the carapace (the exoskeleton of the cephalothorax) and the lateral body wall, in the branchial chamber.
Oxygen and carbon dioxide are exchanged between the blood and water across the gill surface as water is circulated through the branchial chamber by the beating of the gill bailer on the second maxilla.
What is the respiratory rate of infants?
A newborn's respiratory rate may range from 100 to 140 respirations per minute. RBB, MD
100 to 160 is the heart rate for infants, infant respiratory rate is 30 to 60 per min, i really hope that you are not actually a doctor MC EMT-P
What is the role of hair and mucus in our noses?
Mucus is produced in the throat and brushed upwards by tiny hair-like structures called cilia. On its way up to the nose and mouth the mucus traps various dust, dirt and germs you breathe in. When the mucus reaches your mouth you either spit it out or swallow it, where it is dissolved in your stomach acid. If you did not produce mucus you would be more prone to respiratory infections, pepsin enjyme which release in our body do work only in the presence of HCL and mucus prevents the walls of stomach in contact with HCL etc. as the germs would be allowed easy access to your body.
The skin and mucous membranes from the body's first line of defense against disease. Most microscopic pathogens and microbes cannot pass through unbroken skin, although they can easily enter through cuts and other wounds. Mucus membranes protect internal organs that are continuous with the outside of the body.These membranes, which line the respiratory, digestive,urinary and the reproductive tracts, secrete a sticky fluid called mucus,which traps microbes.The mucus may then be expelled from the body, perhaps in a cough or sneeze or in feces.If the mucus are swallowed, digestive juices kill the microbes.
Mucus is a protective layer for internal soft organs/tissues.
In HUMANS, mucus acts as an important unspecific form of defense against pathogens preventing them from entering your body and coating our stomach walls which prevents the highly acidic acids in our stomach from digesting itself.
In ANIMALS, mucus has many roles.
- defense against predators Ex. hagfish
- motion Ex. snails
- homes Ex. cave swiftlet
- hunting Ex. New Zealand glowworm
- bungee (escape) cord Ex. banana slug
Mucus is used to keep foreign substances from getting into your body; in your nose it is used to keep the nasal passage clear of these substances and prevents things such as dust mites, insects, pet dander, etc. from infiltrating your lungs.
Mucus is used to make a bigger loogie.
It traps dirt and germs to prevent your body from becoming infected from disease- causing microbes. It is part of the natural defence system.
The purpose of mucus, also loving termed phlegm or boogers, is to fortify the body from disease.
it stops dust from going into the body
It traps pathogens>>>novanet
^thanks, -pewds
well OK. i think it is easier to go to sleep early. that helps me. but i would say don't use the computer all the time or the TV or video games and other electronics. i would also recommend taking a sleep ade. if you really can go to bed take a sleep ade. OK i also recommend buying a mattress that has advertisements to sleep better. hope this helps. :) other things that may help are:
going to bed on a full tummy and a warm body and wear comfy clothes.
How is the respiratory system affected by pollution?
smoking: lung cancer, caused you to cough grossly and choke
smog: it will make you sick and it could give you cancer
pollen: allergies, sneezing, coughing, ichy eyes and nose, runny nose
Is it possible to die if bleach enters the blood stream?
yes but if ur trying to kill yourself please don’t! your strong! you got this! believe in yourself! i have tried multiple times and yes i did search this to kill myself but i’m not gonna 🥺 people love you! i love u ❤️ stay strong x
What happen if you talk or laugh while eating?
The epiglottis is a movable flap of tissue attached behind/under the tongue which blocks the entrance to the trachea (windpipe) when food is swallowed, thus protecting the lungs by forcing the food to pass over the trachea and instead go down the esophagus into the stomach.
On another hand, talking while eating is not the most attractive habit. No one wants to see chewed-up food!
How does the circulartory system work with the respiratory system?
Actually the circulatory system and respiratory system and digestive system work together by the circulatory system takes oxygen. For example air goes into your heart but first goes to your alveoli and then the blood cells take it to the heart. There the heart does its job and pumps everywhere. the stomach and respiratory are working to with the air.
