Gas Exchange Exam 4 George C Wallace State Community
College-Hanceville BIO 202 Questions with 100% Verified Answers
Latest Update
Question: Answer:
air moving in and out of lungs ventilation
Question: Answer:
exchange of oxygen and carbon dioxide respiration
Question: Answer:
Where is respiration taking place? between the alveolar sacs and the capillaries of the tissues
Question: Answer:
oxygen in the bloodstream oxygenation
Question: Answer:
oxygen to the tissues perfusion
Question: Answer:
What does oxygen and carbon dioxide follow between the -follow concentration gradient going from high to low
bloodstream in the lungs? -CO2 goes from the blood stream, where CO2 is high, into the
lungs, where CO2 is low, to be exhaled
-O2 goes from the lungs, where oxygen is high after
inhalation, and goes into the bloodstream where the oxygen is
low
Question: Answer:
What is the control of our breathing? When can we control it -involuntary
voluntarily? -motor cortex can temporarily override breathing to make it
voluntary for activities such as talking, singing, and swallowing
, Question: Answer:
What is the control center for breathing? brain
Question: Answer:
-located in the medulla, brainstem, carotid artery, and aorta chemoreceptors
-detect changes in pH, O2, and CO2
-send message to change rate of ventilation
Question: Answer:
What is the primary stimulus for breathing? CO2 levels
Question: Answer:
-sensitive to breathing patterns, lung expansion, lung compliance, lung receptors
airway resistance, and
respiratory irritants
-provides feedback to adjust ventilation
Question: Answer:
What are factors that affect ventilation? -rate: tachypnea & bradypnea
-depth:
-lung compliance
-airway resistance
Question: Answer:
-how much your lungs expand to take in air respiratory depth
-affect oxygen and CO2 levels in the blood
Question: Answer:
ease of lung inflation lung compliance
Question: Answer:
-resistance to airflow within the airways airway resistance
-the larger the diameter of the airway, the easier it is to breath
-constriction of the airways in asthma attacks make breathing harder
