Discuss how each of the following influences ventilation:?

Ventilation - the physical act of moving air in and out of the lungs.\n\na)  Passage way resistent would reduce the volume of air that could be inspired - either by hyperinflating the lungs thereby not allowing new air to fill the lungs with breathing OR by the simple resistence itself, no allowing air in (but its usually the former).\n\nb) Decrease lung compliance would reduce the inspiratory volume and therefore decrease ventilation.\n\nc)  If the lungs did not secrete surfactant, the surface tension of alveoli would be much higher and it would not be able to inflate normally.  Therefore ventilation would be reduced again.\n\nSo after I help you with your homework, are you going to buy me lunch?

A few things I can think of right off my head, without reviewing physiology.  Very basic info here, for more details, you can find it in any good physiology textbook.\n\nSmoke in cigarrettes decreases the capacity for hemoglobin to carry O2, and thus decreases the efficiency for O2 diffusion.\n\nCO2 decreases the surfactant in the lungs, making them less efficient in CO2/O2 exchange.\n\nCO2 also damages cells lining the blood vessels (capillaries) that are important in the diffusion process.

Assuming you're talking about in the body: increased ventilation increases the amount of oxygen in your alveoli (lungs) and decreases the amount of CO2, the pH is buffered under normal circumstances by bicarbonate but more CO2 would lower the pH. Decreased ventilation gives the opposite effect of the ones mentioned.\n\nHope this helps

Respiration is a process involving inhalation and exhalation of airs.As for inhalation, the muscles that are involved in it is the diaphragm and external intercostal muscles.During inhalation, the contration of diaphragm (lowered to the abdominal) increased the lungs' volume so that the pressure inside the lungs are lower compared to the atmosphere pressure.As for external intercostal muscles, it help by elavating the ribs cage upward(superior) and forward(anterior).The movement that is made is know as Bucket Handle movement.\n\nAs for exhalation, the muscles that are involved in it is the abdominal muscles and the internal intercostal muscles.During exhalation process, the abdominal muscles contrated and pushed the diaphragm upward, squized the lungs(decreasing the lungs' volume).Decrease in volume caused the pressure inside the lungs are higher than the atmosphere pressure and then we exhaled the air out.As for internal intercostal muscles, it draged the ribs cage downward(interior) and backward or inward(posterior).\nThe two muscles involved in exhalation process only participated only if the process is active.Mostly, the exhalation is a passive movement of the ribs cage due to the elasticity of the lungs and the alveolies.\nIf the person exhaling with force,then the muscles will participate in.\n\nHope this helps ya.\n(^^o)/

these are some factors that i can thought of:\n1) addition/ removal of reactants/products\n2)increase/decrease of pressure of enclosed system containing only gases\n3)increase/decrease of temperature of enclosed system(only for reaction having enthalpy change)

Shear stress, wind loads, dead loads, compression...I think.

Look for connections: causes and effects.\n\nGOOD Question!

The most effective way is with one or more large fans blowing in, on the lowest level of the house, and the windows on the upper level (if there is one) open. By forcing air into the home, you create a positive pressure, and that, along with the fact that hot air rises, moves the air through the home.\n\nIf you ever watch the fire department removing smoke from a building, you will see them using the positive pressure ventilation method

Expansion coefficients for air can be determined using the attached link.\n\nBest wishes !

There are way too many variables for anyone to be able to give you a good answer from the information you gave. I'm an RT & take care of patients on ventilators in the ICU. If you have specific questions, and can share more info, you can email me & I'll try to answer them for you.

hmmm..\nyou can see how albuterol sulfate (asthma medicine) changes someone's breathing or heart rate lol

Respiratory and circulatory.\n\nRespiratory brings oxygen into your body.  Circulatory pumps blood, which carries the oxygen, to the cells in the rest of your body.

Life does not exsist in a vaccuum.  There are way to many variables in every situation, some of which are not noticable.  Wind speed and direction, temperature, barometric pressure, heat index, time, space........and the list goes on and on.

Chemoreceptors in the medulla, carotid arteries and aorta, detect the levels of carbon dioxide in the blood. To do this, they monitor the concentration of hydrogen ions in the blood, which decreases the pH of the blood, as a direct consequence of the raised carbon dioxide concentration.\n\nThe response is that the inspiratory centre (in the medulla), sends nervous impulses to the external intercostal muscles and the diaphragm, via the phrenic nerve to increase breathing rate and the volume of the lungs during inhalation.
