Depending on the volume change in the thoracic cavity, there is a pressure change that leads to a flow of gases to equalize pressure. 

The relationship between the volume and pressure is Boyle's Law. Gases will fill always fill the container they are in. ]]> 2018-04-03 12:15:03 UTC https://padlet.com/angela_almeria23/iq1k92dnus8/wish/248075196 angela_almeria23 https://padlet.com/angela_almeria23/iq1k92dnus8/wish/248079405 Pressure will vary inversely with volume where P1V1= P2V2]]> 2018-04-03 12:27:59 UTC https://padlet.com/angela_almeria23/iq1k92dnus8/wish/248079405 angela_almeria23 https://padlet.com/angela_almeria23/iq1k92dnus8/wish/248080217 External respiration the the exchange of gases between blood and lungs, while internal respiration in the diffusion of gases between blood and tissues.]]> 2018-04-03 12:30:12 UTC https://padlet.com/angela_almeria23/iq1k92dnus8/wish/248080217 angela_almeria23 https://padlet.com/angela_almeria23/iq1k92dnus8/wish/248081222 Oxygen diffuses out of the lungs while Carbon Dioxide diffuses into the lungs.

Oxygen in carried into the blood by dissolving in plasma or they are bound to hemoglobin in the red blood cell. 

Carbon Dioxide is carried into the blood by dissolving in plasma, binding to the globin of the hemoglobin (carbaminohemoglobin), or they are transported as bicarbonate ions in plasma.]]> 2018-04-03 12:33:11 UTC https://padlet.com/angela_almeria23/iq1k92dnus8/wish/248081222 angela_almeria23 https://padlet.com/angela_almeria23/iq1k92dnus8/wish/248084283 Respiration is controlled by brain centers, chemoreceptors, and reflexes.

Respiratory centers are affected by chemicals, influence of the brain, pulmonary irritants and inflation reflexes. ]]> 2018-04-03 12:41:47 UTC https://padlet.com/angela_almeria23/iq1k92dnus8/wish/248084283 angela_almeria23 https://padlet.com/angela_almeria23/iq1k92dnus8/wish/248086236 Hyperpnea: the increase of ventilation in response to metabolic needs. 
EX: When exercising here is an increase in ventilation and when it stops, there is a decline in the flow of Carbon Dioxide.

Acute Mountain Sickness: Quick travel to altitudes higher than 8,000 feet will cause symptoms of headaches, shortness of breath, nausea, and dizziness. This is due to the  change in atmospheric pressure, as Oxygen levels lower. ]]> 2018-04-03 12:47:16 UTC https://padlet.com/angela_almeria23/iq1k92dnus8/wish/248086236 angela_almeria23 https://padlet.com/angela_almeria23/iq1k92dnus8/wish/248151132 Chronic Obstructive Pulmonary Disease (COPD): An umbrella term for a multitude of diseases. Lacking the ability to push air out of the lungs. 

Emphysema: enlargement of the alveoli, causing a lack in elasticity.

Chronic Bronchitis: Excessive mucous caused by inhaled irritants. This results in a blocked airway. 

Asthma: Inflammation of the airways due to a release of interleukins, IgE, and inflammatory cells, causing bronchospasms.

Tuberculosis: An infectious disease caused by a presence of the bacteria Mycobacterium tuberculosis. 

Lung Cancer: Mainly caused by smoking or second-hand smoke. The three most common types of lung cancer are adenocarcinoma, squamous cell carcinoma, and small cell carcinoma.]]> 2018-04-03 15:00:18 UTC https://padlet.com/angela_almeria23/iq1k92dnus8/wish/248151132 angela_almeria23 https://padlet.com/angela_almeria23/iq1k92dnus8/wish/248159770 Going up a mountain too fast can cause altitude sickness. This includes symptoms of nausea, dizziness, headaches, and shortness of breath due to the lack of oxygen in the thinning atmosphere. ]]> 2018-04-03 15:16:28 UTC https://padlet.com/angela_almeria23/iq1k92dnus8/wish/248159770
