When levels equal out then inspiratory muscles relax , the thoracic cavity volume decreases and the the elastic lungs recoil to the smaller size they where at before releasing the 500ml of air, as well as the pressure gradient inside the lungs has now returned to 1 mm Hg. ]]> 2018-04-03 12:15:43 UTC https://padlet.com/ifbbadam_reshkovsky/vuvmmds5cf3i/wish/248075373 ifbbadam_reshkovsky https://padlet.com/ifbbadam_reshkovsky/vuvmmds5cf3i/wish/248075452 measuring the pulmonary ventilation is usually assessed with a spirometer, which uses a hollow bell inverted over water. you bow into it to see how long you can blow air into it and the pressure at what level of air you can blow. it helps evaluate the loss of respiratory function but does not give you an exact diagnosis, more of assess the rate at which gasses move in and out of the lungs. They usually only check for FVC (Forced Vital Capacity) and FEV (Forced Expiratory Volume).]]> 2018-04-03 12:15:59 UTC https://padlet.com/ifbbadam_reshkovsky/vuvmmds5cf3i/wish/248075452 ifbbadam_reshkovsky https://padlet.com/ifbbadam_reshkovsky/vuvmmds5cf3i/wish/248075517 The way that gas is exchanged within the body is mostly by solubility and partial pressure of the gasses. In regards to the air exchange in the lungs, if there is a higher Part pressure of oxygen in the lungs gasses compared to the blood in the alveoli, then the oxygens partial pressure is higher thus causing it to be forced into the blood and at the same time having a lower carbon dioxide partial pressure in the lung's air so it pushes the carbon dioxide form the blood into the air in the longs to expel it. this same process happening everywhere else in the body, the higher partial pressure, the more it will be pushed out of that area. ]]> 2018-04-03 12:16:15 UTC https://padlet.com/ifbbadam_reshkovsky/vuvmmds5cf3i/wish/248075517 ifbbadam_reshkovsky https://padlet.com/ifbbadam_reshkovsky/vuvmmds5cf3i/wish/248075616 The main way that oxygen and carbon dioxide travel through the blood is by the affinity that the molecules have with Hb. The higher the partial pressure of oxygen there is at the area, such as in the lungs, the stronger the affinity hemoglobin has of oxygen. When HB becomes fully saturates with oxygen it then becomes oxyhemoglobin, once this oxyhemoglobin and to the tissues where the partial pressure of carbon dioxide is higher the affinity to oxygen is less compared to the affinity to carbon dioxide so carbon dioxide binds to the HB becoming deoxyhemoglobin. ]]> 2018-04-03 12:16:35 UTC https://padlet.com/ifbbadam_reshkovsky/vuvmmds5cf3i/wish/248075616 ifbbadam_reshkovsky https://padlet.com/ifbbadam_reshkovsky/vuvmmds5cf3i/wish/248075738 contro of respiration primarily involves neurons in the reticular formation of the medulla and pons within the brain. The VRG that extend from the spinal cord to the pons which is the rhythm center and integrative center. with the VRG, inspiratory and expiratory impulses fire to the phrenic and intercostal nerves causing the thorax to expand and or relax. DRG is still to this day not completely understood but assists the VRG with impulses as well as the chemoreceptors. ]]> 2018-04-03 12:16:57 UTC https://padlet.com/ifbbadam_reshkovsky/vuvmmds5cf3i/wish/248075738 ifbbadam_reshkovsky https://padlet.com/ifbbadam_reshkovsky/vuvmmds5cf3i/wish/248075763 Atelectasis - or a collapsed lung happens when an alveoli collapses or a ruptured visceral Plura and the negative sustaining pressure becomes a positive pressure and doesn't allow that lung to inflate being equal to the atmospheric pressure.  ]]> 2018-04-03 12:17:04 UTC https://padlet.com/ifbbadam_reshkovsky/vuvmmds5cf3i/wish/248075763 ifbbadam_reshkovsky https://padlet.com/ifbbadam_reshkovsky/vuvmmds5cf3i/wish/248075842 Higher altitude effects on the body are substantial, for when a person travels to a high elevation of 8000 feet from sea level fast, they then can start getting affects of ALS or altitude sickness. ALS, will start giving the person effects such as nausea, dizziness. This is all due to your body being accustomed to the sea level of ATM pressure and having to adjust to the Arm at 8000 feet. for long term acclimation, your body creates more EPO so that it can create more read blood cells for varying and absorbing more the oxygen at the higher altitude. ]]> 2018-04-03 12:17:23 UTC https://padlet.com/ifbbadam_reshkovsky/vuvmmds5cf3i/wish/248075842
