Respiration Anatomy and Physiology Quiz


The ____ sits on top of the uppermost tracheal ring

A. larynx

B. esophagus

C. thorax

D. diaphragm

serves as a partial attachment for many muscles, the smallest

A. the manubrium

B. the corpus

C. the xiphoid process

During quiet/passive exhalation____ from the stretched inspiratory muscles is released

A. potential (stored) energy

B. active expiratory pressure

C. recoil forces

D. non-muscular forces

breath hold, bare down (e.g., giving birth)

A. intra-thoracic pressure

B. abdominal unit

C. external intercostal muscles

D. negative subglottal pressure

elastic tissue that inflates and deflates and as a result move air

A. lungs

B. trachea

C. thorax

D. ribs

passive expiration is accomplished by

A. non-muscular forces (recoil forces)

B. muscular forces

C. potential (stored) energy

D. passive expiratory pressure

the smallest branches stemming from the secondary bronci, lead to the alveoli where gas exchange occurs allowing air to enter into the blood

A. bronchioles

B. thorax

C. lungs

D. diaphragm

serves for attachment of certain respiratory muscles like the trapezius, pectoralis major and sternocleidomastoid

A. clavicle

B. sternum

C. abdominal wall

D. bronchi

for the lungs to inflate (inspiration), alveolar pressure must be more than atmospheric pressure



the act of inspiration is always passive



supplies innervation to the diaphragm

A. phrenic nerves ( C3,4,5)

B. spinal nerves



the lungs are apposed (or connected) to the thorax by….

A. pleural linkage

B. visceral pleura

C. parietal pleura

D. functional residual capacity

the chest cavity that surrounds and protects the lungs, the heart, and other respiratory structures

A. thorax

B. ribs

C. diaphragm

D. abdominal wall

alveolar pressure is changed by 2 forces: passive and active forces



neither the lung nor the thorax is really at their respective rest position

A. functional residual capacity

B. visceral pleura


D. pleural linkage

consists of 3 processes that serve as attachments for the respiratory muscles: manubrium, corpus, xiphoid process

A. sternum

B. abdominal wall

C. thorax

D. trachea

developed by the contraction of the respiratory muscles, alveolar pressure is changed by____

A. passive force

B. active force

When the respiratory system is at rest, the lungs are partially ____ at “rest”

A. inflated

B. deflated

has passive and active properties, during effortful tasks like coughing, sneezing, and certain voicing tasks, it contracts to compress the contents inside

A. abdominal wall

B. diaphragm

C. sternum

D. clavicle

a membrane that covers the lung

A. visceral pleura

B. parietal pleura

C. pleural linkage

during inhalation the lung volume increases, air molecules are less compressed, creating a vacuum called…

A. negative subglottal pressure

B. abdominal unit

C. intra-thoracic pressure

D. sternum

diaphragm and external intercostal muscles

A. muscles of quiet inspiration

B. muscles of forced inspiration

when the diaphragm moves downward and the force is transferred to the lower ribs moving them outward, the pressure rises and the lower rib cage….

A. expands

B. shrinks

C. rests

D. contracts

a membrane that covers the thorax

A. visceral pleura

B. parietal pleura

C. pleural linkage

For air to flow out of the lungs (expiration), alveolar pressure must be less than atmospheric pressure
