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.

How does emphysema affect a person's alveoli?
*IT* Doesnt
Emphyesma is when alveoli die.
how does it affect them...
Well it would affect them like it affects every other cell in the body.
(decreased O2)
but it acually doesnt affect the alveoli
it just happens
when they die
Why is hair important to the human body?
Human body hair might seem to be useless on today's modern man, but it could help us detect parasites, researchers suggest, adding there's a chance our female ancestors preferred a bug-free mate, and so opted for hairier guys.
What happens as air passes through the nasal passage?
the oxygen we inhale will reach lungs . the hemoglobin will bind with oxygen through iron present in hemoglobin as (Fe2+).and it will reach blood cells. the myoglobin present in the cells will bind with the oxygen which is already bonded with the hemoglobin. coz myoglobin have greater affinity than hemoglobin.then hemoglobin picks up co2 from myoglobin will reach lungs ,finally we exhale.
What is the site of anaerobic respiration?
In fast twitch muscles.Aerobic respiration occurs in the mitochondria.
Which principle normally prevents the alveoli from collapsing during expiration?
cardiac output can be determined by the following formula
What is a effect on a long term on the respiratory system in a exercise?
While exercising the muscles use oxygen and produce carbon dioxide. The lungs and heart respond by supplying extra oxygen. Breathing increases and you breath deeper to maximize intake. Heart rate increase to transport the oxygenated blood to the muscle.
What is the intake of air in the respiratory system?
To allow the air to enter the body. The air can enter through either the nose or through the mouth.
Why do your lungs expand during inhalation?
The diaphragm below the lungs, which one of the body's strongest muscles, lowers and raises again, drawing air into the lungs and pushing it back out again. "Hiccups" (hiccoughs) are caused when a stimulus of the vagus nerve triggers a sudden lowering of the diaphragm, drawing air in and forcing the vocal cords closed in the larynx.
Why do mammals need the respiratory system?
so that they can breath. If you do not know the respiratory system is used for breathing
Does the respiratory system remove waste?
Yes, the respiratory system removes waste. Besides providing oxygen to the lung and the cells of a body during inhalation, they also provide some nutrients as well. Therefore when a person is exhaling, carbon dioxide is picked up from the cells along with waste (unused or used nutrients) and is breathed out.
Why does the respiratory system need so many structures?
This is in order to increase the surface area available to the blood that carries the red blood cells in it, in order to maximize the amount of oxygen and carbon dioxide transfer that is needed to keep you alive.
What is the definition of the respiratory system?
what do you mean by your? I will tell everything I know about the respiratory system.
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)
Which muscles are involved in inhalation and exhalation?
The diaphragm & the external intercostal muscles (the muscles between the ribs that course downward) are the two most important muscles of inhalation, but there are many other muscles that also contribute to this process.
Other muscles of inhalation include:
-Pectoralis major
-Pectoralis minor
-Serratus anterior
-Costal levators
-Subclavius
-Serratus posterior superior
-Serratus posterior inferior
What is the function of respiratory membrane?
it is a barrier across which gases are excahnged betwween alveolar air and the blood. it helps prevent each alveolus from collapsing as air moves in and out during respiration
Waste product given off in the gas exchange between air and blood in the alveoli?
Carbon Dioxide. (CO2 )
How does the renal system compensate for conditions of respiratory alkalosis?
It expels or retains carbon dioxide in the blood.
What is the advantage of having a bladder for temporary storage of the urine?
It is because the kidneys do not hold urine and merely acts as a filtering system, so if no bladder is present, the urine will freely pass through.
What parts of the respiratory system function as the main sites of gas exchange?
In the respiratory system, it is the alveoli.
In the circulatory system, it's the capillaries.
They are similar in that both have walls that are only one cell thick, they are both the thinnest parts of their systems, and they are right next to each other. (They diffuse through to each other.)
In the respiratory system it's the Alveoli and in the circulatory system it's the capillaries :D
How does the integumentary system contribute the cardiovascular system?
One of the functions of the integumentary system is to regulate body temperature. It does so by using the APM (arrector pili muscle) to raise arm hairs and help increase body temperature when cold by using this muscle contraction and to help trap and warm air underneath these hairs.
The circulatory system is also responsible for helping regulate body temperature. It does so by allowing the blood vessels to vasodilate (widen) or vaso constrict (become smaller). When the blood vessels dilate what else does the heat escape through than the integumentary system (the skin).
Function of the larynx in the respiratory system?
The larynx is where the vocal cords are located. The cords tighten and relax to change the pitch of the voice.
Actual sounds are produced by the mouth and nose by changing the shape and the speed of the air as it passes through the chambers.
In societies that incorporate non-tonal sounds into their language (such as certain cultures in Africa that utilize clicks), these sounds are produced by the tongue.
What are the long term effects of exercise to the cardio vascular system?
Your body will have a shorter recovery time as your fitness levels get better. The heart would need to beat less just to pump the same amount of blood as before. The heart increases in size and so does the muscle tissue due to the long time in training. The strength of the contractions also increases and so the does the blood being pumped every beat.
