PSY320H1 Chapter Notes -Partial Pressure, Ph, Circulatory System
Document Summary
Provide an extensive area for gas exchange between air and circulating blood. Moving air to and from the exchange surfaces of the lungs. Protecting respiratory surfaces from dehydration, temperature change, or other environmental variations and defending the respiratory system and other tissues from invasion by pathogens. Producing sounds involved in speaking, singing, and non-verbal communication. Providing olfactory sensations to the cns from the olfactory epithelium in the superior portions of the nasal cavity. Acute bronchitis usually results from an infection such as cold or flu. Gas diffusion across the respiratory membrane and across capillary walls. The transport of oxygen and carbon dioxide between alveolar capillaries and capillary beds in other tissues. Gases moves from areas of high pressure to areas of low pressure. Inhaling/exhaling pressure intrapulmonary or intra alveolar pressure- measured inside the respiratory tract at the alveoli during inhalation, intrapulmonary pressure is 759mmhg. During exhalation, intrapulmonary pressure is 761 mmhg.
