Structures
This is the anatomical term for the opening of the larynx.
What is the glottis?
A condition that causes constriction of the bronchioles, often due to an allergic reaction.
What is asthma?
This is the main function of the respiratory system. (Two words)
This system is most closely related to the respiratory system because it transports oxygen throughout the body.
What is the cardiovascular system?
(also: circulatory system)
This type of tissue is only one layer thick and has flattened cells.
What is simple squamous?
The major function of this structure is swallowing.
What is the pharynx?
This disease, caused by smoking and pollution, damages the alveoli in the lungs and disables their elasticity, making it difficult for a person to exhale.
What is COPD?
(Also: Chronic Obstructive Pulmonary Disease)
This muscle receives nerve impulses from the brain and contracts downward for breathing to occur.
What is the diaphragm?
The function of these is to keep the trachea open so air can pass through.
What are cartilage rings?
This type of muscle is both voluntary and striated.
What is skeletal muscle?
The anatomical term for this structure is the "voice box".
What is the larynx?
A lack of surfactant in the alveoli often causes this disorder to occur in newborns.
What is Respiratory Distress Syndrome?
(Also: Infant Respiratory Distress Syndrom, RDS, IRDS)
Suction between the plueral membrane and lungs cause the lungs and chest cavity to do this, which creates space for oxygen to fill.
What is expand?
The function of this structure is to keep food and liquids from entering the larynx when swallowing.
What is the epiglottis?
This bone in the arm is often referred to as the funny bone.
What is the humerus?
The function of these is to filter air by blocking dust and debris from entering the nose.
What are nasal hairs?
(Also: nose hairs)
This disorder which is caused by damage to the alveoli, making it difficult to breath, can lead to COPD.
What is emphysema?
This is left in the lungs after the deepest possible exhale to ensure that gas exchange continues between breaths.
What is residual volume?
This type of membrane lines the upper respiratory system and contains goblet cells that secrete mucus.
What are mucus membranes?
To bring a structure toward the midline is to do this.
What is to adduct?
These three structures protect the lungs.
What are serous fluid, rib cage, and plueral membranes?
A healthy, non-smoker woman who is 9 months pregnant complains to her doctor that she is having trouble breathing. This is most likely the cause of her labored breathing.
What is the baby pushing up against her diaphragm, preventing the lungs from expanding fully?
A change in this triggers the medulla to send nerve impulses to the diaphragm and intercostal muscles.
What is pH?
This fluid in the plueral cavity is important for keeping the alveoli inflated.
What is surfactant?
(also: serous fluid)
This is the upper chamber of the heart that blood enters after returning from the lungs.
What is the left atrium?
