- When the peripheral chemoreceptors detect low oxygen levels, they stimulate the respiratory areas of the brain to _________ breathing rate.
- What structures monitor the level of oxygen in arterial blood?
- With each breath, some inspired air does not reach the alveoli and, thus, does not participate in gas exchange. The term _________describes this volume of air.
- carbon dioxide diffuses from _______ to ______
- What effect will hyperventilation have on the blood carbon dioxide level?
- respiratory group that establishes basic rhythm of breathing
- the respiratory membrane consists of the alveolar wall and the ________
- the _______ separates the capillary blood from the alveolar air.
- respiratory group that processes sensory input and stimulates inspiratory muscles
- The stomach receives food from _____ and sends it to the ____
- Enzyme that is secreted in low levels to stimulate production of gastric juice
- What is the volume capacity for the average human stomach? ( in liters )
- Proteins are digested into their building blocks called....
- decrease in thorax width, ribs move out and in, internal intercostals contract, diaphragm moves superiorly
- What nonrespiratory air movement is due to a spastic contraction of the diaphragm while the glottis is closed?
- true or false: Inspiration is a passive process, relying on tissue recoil to change thoracic volume.
- What nonrespiratory air movement helps to clear the upper respiratory passageways?
- during inspiration, the pressure within the lungs is _______ than atmospheric pressure.
- As the intercostal muscles relax and the thoracic cavity becomes smaller, the alveolar pressure
- during expiration, the pressure within the lungs is _______ than atmospheric pressure
