1
The pressure exerted by the air surrounding the body is called _____________ pressure
2
During ____________, the diaphragm and external intercostal muscles contract to increase thoracic volume
3
The pressure inside the alveoli is known as ______________ pressure.
4
________ expiration is an active process that involves contraction of the abdominal muscles and internal intercostals.
5
The process of moving air in and out of the lungs.
6
Expiration during quiet breathing is a _________ process because it relies on the natural recoil of the lungs.
7
The pressure in the pleural cavity is called intrapleural pressure, and it is always negative under normal conditions.
8
A rupture of the ________ pleura can lead to pneumothorax by allowing air to enter the pleural space.
9
When intrapleural pressure equals atmospheric pressure, the lung will __________.
10
The muscles primarily responsible for quiet breathing are the _________ and the external intercostal muscles
11
During __________, the volume of the thoracic cavity decreases, causing the intrapulmonary pressure to rise.
12
A rupture of the _________ pleura can cause air to leak from the lungs into the plural cavity, leading to lung collapse.
13
The difference between intrapulmonary and intrapleural pressure that keeps the lungs inflated is called ____________ pressure.
14
Forced inspiration involves additional muscles, including the sternocleidomastoid, _________, and pectoralis minor.
15
Intrapleural pressure is always ____________, meaning it is lower than both atmospheric and intrapulmonary pressure.
16
During quiet breathing, intrapulmonary pressure becomes slightly ________ than atmospheric pressure during inspiration, allowing air to flow into the lungs.
17
The total amount of exchangeable air in the lungs is known as __________ capacity.
18
The major chemical factor that influences the rate and depth of _____________ is carbon dioxide levels in the blood
19
The volume of air moved in and out of the lungs during normal breathing is called ________ volume.
20
The sticky, watery secretion that lines the alveoli to prevent their collapse is called __________.
