The primary chemical stimulus for breathing is the concentration of:
medulla oblongata & pons and the amount of CO2 in the blood
What is respiration rates mainly controlled by?
What makes the trachea rigid to keep the airway open, make the bronchi rigid to keep them open, are C shaped in the trachea to allow the esophagus to expand behind it, are not found in the esophagus?
What is the flap of cartilage that closes off the larynx and prevents food and water from entering the larynx during swallowing is the:
A) transport of nutrients to tissue
Which of the following is not a function of the respiratory system?
A) transport of nutrients to tissue.
B) ventilation of lungs.
C) Gas exchange between lungs and blood.
D) gas exchange between blood and cells.
E) production of sound.
All of them affect the release of oxygen
Which of the following affect the release of oxygen from hemoglobin?
A). partial pressure of oxygen
C) acidity and exercise
D) carbon dioxide in the tissue
B) smoker's cough and brochitis
C) lung cancer
D) increased mucous
What are some effects that smoking can cause?
C) less carbon dioxide is produced
Changes in the respirtatory system during exercise include all but which of the following:
A) increase in blood flow to the lungs
B) oxygen diffusion rate increases
C) less carbon dioxide is produced
D) ventilation rate increases
E) ventilation depth increases
True or False: In order for respiration to occur, the volume of the lung needs to be increased.
True or False: The nasal cavity is divided into top, middle and bottom portions by nasal conchae and into a right and left side by the nasal septum. The purpose is to circulate air to warm, cleanse, examine and moisten it.
True or False: The total pressure of a gas mixture is calculated by multiplying the partial pressures.
True or False: The transport of respiratory gases between the lungs and body tissues is a function of the blood.
True or False: During inspiration the diaphragm contracts and drops which increases the thoracic cavity's size and decreases its pressure. Expiration is the reverse, volume decreases and pressure increases forcing air out.
True or False: If alveolar PCO2 is low, CO2 will diffuse from the capillary blood into the alveoli.
True or False: The right lung is smaller than the left lung because of the position of the heart.
True or False: Parietal pleural membrane lines the thoracic cavity while the visceral pleural membrane covers the lung.
True or False: Cigarette smoke is the single most preventable cause of death and disability worldwide
True or False: While laryngitis is common among all people, cancer of the larynx is found almost exclusively with those who smoke.
True or False: Shallow breathing is called diaphragmatic breathing while deep breathing involves the ribs and so is called costal breathing.
True or False: Hypocania caused from voluntary hyperventilation can be dangerous, especially to swimmers, because the oxygen level may from dangerously low and cause fainting.
The branches of the trachea to the bronchi and bronchioles is referred to as the _____.
Heimlich or Abdominal thrust maneuver
The maneuver used to expel an aspirated object is called the _____ maneuver.
minute volume of respiration
The total volume of air taken in during one minute is called the _____.
The air that remains in the lungs after the expiratory reserve volume is expelled, is the _____.
The passive process by which air flows into and out of the lungs is called ______.
The immediate increase in ventilation at the onset of exercise is a result of the stimulation of _______.
What is it called when alveolar walls lose their elasticity and remain filled with air during expiration?
SIDS (sudden infant death syndrome)
What kills infants between the ages of 1 week and 12 months, without warning?
What is an abnormal accumulation of interstitial fluid in the interstitial spaces and alveoli of the lungs?
nose, pharynx, larynx, trachea, bronchi, bronchioles, terminal bronchioles
Name, in correct order, the conducting portion of the respiratory system.
1. They warm, moisten, and filter incoming air.
2. They receive olfactory stimuli.
3. They provide a resonating chamber for speech sounds.
Name the function of the interior structures of the nose.
1. Pulmonary ventilation is the movement of air in and out of the lungs, inspiration occurs
when the pressure inside the lungs is lower than the atmospheric pressure. This is achieved by increasing the volume of the lungs. Expiration occurs when the pressure in the lungs is greater than the pressure of the atmosphere. This occurs when the size of the thoracic cavity decreases.
2. External respiration is the exchange of gases between the air in the alveoli and the blood.
3. Internal respiration is the exchange of gases between the blood and tissues.
Name and briefly describe the three basic processes of respiration.
