BIOD 151 Module 2 Updated Version Questions and Correct Answers Score 100% advantages of shared passageway of the pharynx - Correct Answer 1) air can enter through the mouth when nasal cavity is obstructed 2) allows for relatively normal breathing while eating 3) greater air intake during heavy exercise that requires more gas exchange
aerobic cellular respiration - Correct Answer Process of making ATP for cellular work
alveolar macrophages - Correct Answer dust cells
alveolar sacs - Correct Answer clusters of alveoli
alveolar ventilation - Correct Answer movement of air into and out of the alveoli
Alveoli - Correct Answer tiny sacs of lung tissue specialized for the movement of gases between air and blood represent the site of gas exchange and blood-air barrier
aspiration - Correct Answer when food or liquid accidentally enters the trachea may cause pneumonia
Auscultation - Correct Answer listening to sounds within the body (usually with a stethoscope)
benefit of incomplete ventilation - Correct Answer air entering the lungs mixes with the air already in them which helps conserve water and maintain a constant temperature
Boyle's Law - Correct Answer P1V1=P2V2 explains why inspiration and expiration can take place
breathing - Correct Answer movement of air into and out of the lungs includes inspiration and expiration
Bronchi - Correct Answer the branches located at the lower end of the trachea that carry air into the lungs.the two main ones enter left and right lungs they further divide
Bronchioles - Correct Answer Airways in the lungs that lead from the bronchi to the alveoli interface b/w conducting and respiratory portions of system
capillaries are typically sandwiched b/w - Correct Answer two separate alveoli
- / 2
carbaminohemoglobin - Correct Answer CO2 combined with hemoglobin
Charles's Law - Correct Answer V1/T1=V2/T2 explains why warming air is beneficial to the respiratory system
cilia - Correct Answer small hairlike structures
Columnar - Correct Answer taller than wide
cystic fibrosis - Correct Answer A genetic disorder that is present at birth and affects both the respiratory and digestive systems.causes epithelial cells to produce mucus w/o enough saline. mucous gets too thick and clogs resp tract.
Dalton's Law - Correct Answer The total pressure of a mixture of gases is the sum of the individual pressures (ppO2 + ppCO2 + ppN2 = 1atm) different gas quantities or partial pressures in the body which affects diffusion
delivery of O2 to cells is promoted by - Correct Answer an O2 carrying molecule such as hemoglobin
Diaphragm - Correct Answer muscle that is dome-shaped at rest but flattened as it contracts pulls lungs open negative pressure in the lungs meCorrect Answer air naturally flows inward
diffusion - Correct Answer gas exchange between the air in the alveoli and the blood in pulmonary capillaries
Diffusion is enhanced by - Correct Answer extensive vascularization of the lungs
Emphysema - Correct Answer disease in which the alveoli are damaged. inner walls of alveoli become week and rupture, causing a loss of alveolar ventilation ability and loss of total gas exchange because of the loss of alveoli often caused by smoking
epiglottis - Correct Answer a flap of cartilage at the root of the tongue, which is depressed during swallowing to cover the opening of the windpipe/larynx
Esophagus - Correct Answer A muscular tube that connects the mouth to the stomach.lies posterior to the larynx and trachea
Eustachian tube - Correct Answer connects the middle ear with the nasopharynx and allows passage of air
expectorate - Correct Answer cough or spit out phlegm from the throat or lungs
