Question 4
Question
Complete this description of INHALATION..
Inhalation occurs when the [blank_start]diaphragm[blank_end] contracts and [blank_start]drops[blank_end]. This causes the lung volume to get [blank_start]larger[blank_end] which creates a [blank_start]negative[blank_end] pressure difference. Air then rushes [blank_start]in[blank_end].
