Which of the following is a function of the respiratory system?

Elimination of nitrogen waste (ex. ammonia)

What is the correct sequence for the passageway of air through the respiratory system?

-Trachea - Terminal Bronchioles

-Nasal Cavity - Alveolar Sacs

-Alveolus -Secondary Bronchi

-Primary Bronchi

Nasal Cavity


Primary Bronchi

Secondary Bronchi

Terminal Bronchioles

Alveolar Sacs


Which of the following are true regarding the true vocal cords?

-They are Found in the larynx

-Vibrations of the anterior folds=increase frequency and pitch

-Vibrations of the longer sections=decrease frequency and pitch

What are the purpose of the cartilage rings?

Prevents the trachea from collasping

The conduction zone of the tracheobronchial tree ends at the

Terminal Bronchioles

This is the primary gas exchange site


Which of the following cells of the alveoli produce surfactant?

Type 2 Alveolar cells

When the inhalation muscle contract...

The size of the thoracic cavity increases in length

The size of the thoracic cavity increases in diameter

Exhalation begins when

Inspiratory muscle relaxes

During the process of expiration/exhalation, the alveolar pressure is

Greater than the barometric pressure

Pulmonary surfactant acts to

-Lower the surface tension of the alveoli

-Prevent the barometric pressure

-Prevent dehydration of the alveolar surface

- Keep the alveoli from sticking together

This means the lung and chest wall expand easily

High Compliance

This part of the pharynx extends from the nasal cavity to the soft palate


You are traveling in a space capsule that has lost all power to control the atmosphere. If the pressure inside the capsule is now 900mmHg and the concentration of oxygen is 20%, what would the PO2 be?


Given these lung volumes, calculate the vital capacity

1. Tidal volume=500ml

2. Inspiratory reserve volume=2500ml

3. Residual Volume=100ml

4. Expiratory reserve volume=100ml

5. Dead Space=100ml


Which of the following is incorrect

-decrease surface area in the alveoli, decrease rate of gas exchange

-Increase the partial pressure differences of gases, decrease rate of gas exchange

-increase the diffusion distance across the respiratory membrane, decrease the rate of gas exchange

-Increase the partial pressure difference of gases, increase rate of gas exchange

Increase the partial pressure differences of gases, decrease rate of gas exchange

Which of the following would increase hemoglobin's ability to bind oxygen?

-decrease in temperature

-increase in blood pH

-decrease in blood CO2 concentration

-All of These

All of these

Oxygen is mostly transported in the blood

bound to hemoglobin

Most of the CO2 is transported in the blood is

in the plasma as the bicarbonate ion (HCO3)

An enzyme that speeds up the reaction of carbon dioxide and water:


Carbonic Anhydrase

When bicarbonate ion diffuses out of red blood cells into plasma, it is usually exchanged with which ion


The respiratory areas that controls the basic rhythm of respiration and transitions between inhalation and exhalation are located in the

pons & medulla oblongata

The chemoreceptors in the aortic and carotid bodies:

-affects the respiratory center when blood carbon dioxide levels change

-affects the respiratory center when blood pH changes

- affects the respiratory center when blood oxygen levels change

- All of these

All of these

The residual volume is the amount of air

remaining in the lungs after forced expiration

The tidal volume is

Volume of air moved in and out of the lungs in a single quiet breath

Results in the loss of cilia, increases accumulation of mucus

Whooping Cough

Results in the formation of a grayish membrane in the throat


An inherited disorder that affects secretory cells and increases mucus formation

Cystic Fibrosis

Controls the ability to voluntarily hold your breath

cerebral cortex

Collapse of lungs in premature infants

Respiratory Distress syndrome

The blood flow resistance in the efferent arteriole is greater than the blood flow resistance in the afferent arteriole


Fever production enhances the activities of the immune system


The fluid from blood capillaries that is found between cells is called lymph


A graph versus host rejection occurs when the recipient recognizes the donor tissue as foreign
