Why does the respiratory system need the digestive system?
The respiratory system consists of living tissue that requires food to survive. The digestive system processes the food you eat and turns it into a form that can be carried to the cells of the respiratory system so they can be well nourished and keep the respiratory system functioning properly..
What is the respiratory system?
The respiratory system one of the major systems in the human body. Its major purpose is to control breathing, which is an autonomic response of the lungs. Respiratory system comprises of the two Lungs in the chest and the tubes called bronchus and trachea. It is responsible for your breathing and gas exchange whereby blood gets oxygenated and purified .
your respiratory system is the sysetm that you use to breathe. It inludes your nose and mouth and it goes right down to your lungs.
If your nose and mouth are covered with hands will you pass out?
Yes, if covered tightly enough (air tight) to keep adequate oxygen from getting into to your lungs.
People pass out when enough oxygen can't get to their brains from the blood stream to keep fully functioning. If the oxygen gets used up and isn't replenished through breathing air in and out of the lungs, then you could pass out, and if deprived of oxygen for too long, you could have brain damage or even die from the lack of blood flow and oxygenation.
The same effect can come from choking or strangling or other types of airway obstructions that prevent proper blood flow to the vital organs. It is not good for your body to have even short periods of low oxygenation, so it is not something to do casually or on purpose.
Insects do not have lungs, they breath passively by diffusion through tiny holes in the abdomen.
true
What is frontal sinuses in respiratory system?
Frontal sinuses in respiratory system are younose and eyes.
What are the respiratory system?
1. The prime organs participating in the breathing process are the lungs and the diaphragm. These are supplemented by the rib cage and surrounding muscles and activated by one of two nerve systems. One is the automatic breathing you will notice as you go to sleep while the main waking system is at your will. As when blowing out a candle or speaking.
2. My answer is diaphragm (the thing under the lungs that relaxes and tightens as you breathe), bronchus (A bronchus is a main branch of the airway located below the trachea and above the bronchioles), trachea which is also the windpipe (it is connected to the lungs and the air goes through it), pharynx (The pharynx is the section of the throat between the skull and the esophagus that propels food when swallowed into the esophagus. The epiglottis at the bottom of the pharynx pivots to send food to the esophagus or air into the lungs), larynx (The hollow muscular organ forming an air passage to the lungs and holding the vocal cords in humans and other mammals; the voice box) and there is this thing that is not really important to know called bronchial tubes. It goes into the two lungs, so air goes through it. Did you know that the left lung is smaller than the right lung to have more room for the heart? (By the way,this was made by founders0's sister)
Does breathing into a brown paper bag trigger the brain to take slower deeper breaths?
no it does not trigger the brain. it increases the amount of carbon dioxide in your air intake to your lungs. when a person feels anxious or starts to feel like they cant get enough oxygen into their lungs they start to breath more shallow and repeditivley. when you breath too quickly you lose the carbon dioxide from your lungs thus people use a paper bag to retain the co2 instead of it releasing into the atmosphere. theoretically it doesnt have to be a paper bag it could be anything that could hold your breath for rebreathing.
Anoxia, the severest form of hypoxia, is caused by extreme deprivation of oxygen.
The causes of anoxia are:
- Severe anemia.
- Low partial pressure of oxygen in blood (Hypoxemia).
- Premature birth
- Lung diseases like asthma

What tissue forms the inner lining of the respiratory passages?
The type of epithelial tissue that lines much of the respiratory tract is called pseudostratified columnar. This type of tissue also moves substances across its surface.
The Heimlich Maneuver.
What is the thickness of the respiratory membrane?
The average thickness of respiratory membrane is 0.2 Mm
How do the digestive and respiratory systems work together?
After we eat, the food is broken down by the digestive system and then it mixes with oxygen to produce blood.
How does the epiglottis behave .What would happen it you talk while eating?
The short answer is : the epiglottis is a movable flap of tissue attached behind/under the tongue which blocks the entrance to the trachea. There is also a sound box called Larynx which sends out vibrations when we talk and due to this vibrations the flap opens and sometimes food goes inside and we start coughing. If you talk while eating, and you happen to be a toddler, your Mum will tell you off. If you talk while eating, and you are older than that, people may think you are a bit of a pig.....
What is the respiratory surface for protists?
the respiratory surface for protists is the alveolis and capillaries
Which system contains the diaphragm?
The diaphragm belongs to the Muscular and Respiratory systems.
Respiratory
The diaphragm is part of the respiratory system.
The diaphragm is a large, dome-shaped muscle that plays an important role in breathing. Therefore, even though it helps out with breathing, it is a part of the muscular system.
People breathe through their lungs using their respiratory system.
Inhalation occurs when the diaphragm (a muscle under the lungs) pushes down on internal organs, freeing up space for the lungs to expand. The intercostal muscles between ribs also elevate the rib cage and push it out. The expansion creates negative pressure in the lungs, and the higher pressure of the atmosphere draws air into the lungs. The oxygen diffuses into the blood running through the capillaries around the alveoli, sacs that line the lungs. Carbon dioxide also moves to a lower concentration to the interior of the lungs from the blood.
Exhalation is essentially the opposite process: the diaphragm and ribs relax, creating positive pressure within the lungs and pushing the carbon dioxide out. The actions of the diaphragm and other muscles is controlled in the areas of the brain, not conscious thought, which makes breathing while sleeping possible.
when you breathe in your diaphgram flatens as your lungs expand.when you breathe out your diaphgram relaxes and takes a dome shape and your lungs collapses.
By flexing the diaphragm below the lungs. This creates a vacuum to suck air in and then pushes the air back out. A popular illustration of how this works is to put a deflated balloon in a 2 liter bottle with the bottom cut off. Hang it so that the balloon is inside but the neck of the ballon is stretched over the opening. Then take plastic wrap or a sheet of rubber the fasten it to the bottom, make sure it isn't stretched tightly, there needs to be some give, and make sure that the excess is in the bottle. Once it is airtight, pull down on the plastic wrap. This makes the space inside the bottle larger, but no extra air can get in to fill it. So, the balloon inflates to take up the new space. Now, push the plastic back up into the bottle. There isn't enough room anymore for all the air. So, the air in the ballon is expelled. Hope this helps!
It is an involuntary motion control by the cerebelum which is dorsal to the brain. It consisit of abdomen movements to put air into the lungs and to empty it.
the diaphram ,which is a muscle under the lungs, contracts and pulls the lungs down, expanding them and filling them with air, we only realise the air when we relax this muscle, if you realse the musle to quickly you can often damage the tissue, hence we breath in and out at a steady pace.
the oxygen is passed through the pharynx and larynx which pass into the trachea and it branches into the bronchi through the lungs and back up in reverse.
With lungs! Without lungs there would be no place for the air to go.
