Q

External respiration

A

Gas exchange process that occurs between the alveoli and the surrounding pulmonary capillaries. Also referred to as alveoli/ capillary gas exchange, serves to oxygenate the blood and eliminate CO2 in the lungs.

Q

Internal respiration

A

AKA cell/capillary gas exchange, is responsible for delivering oxygen to the cells and removing CO2 from the cell. Gas exchange process that occurs between the cells and the systemic capillaries.

Q

Cellular respiration and metabolism

A

AKA aerobic metabolism, occurs in the cell. Process breaks down glucose in the presence of oxygen, produces high amounts of energy in the form of ATP, and releases CO2 and water as a by-product.

Q

Chemoreceptors

A

Continuously monitor levels of oxygen, carbon dioxide, and pH (hydrogen ion concentration) in the arterial blood and stimulate an increase or decrease in the impulses from the respiratory rhythm centers to control the rate and depth of ventilation.

Q

Hemoglobin

A

Found in the cytoplasm of red blood cells, is responsible for picking up most oxygen in the blood, approximately 97 percent, and carrying it through the arterial system to the capillaries throughout the body. protein molecule in red blood cells that carries oxygen from the lungs to the body’s tissues

17
Q

An Open airway

A

Patent airway

18
Q

Snoring

A

Occurs when the upper airway is partially obstructed by the tongue or by relaxed tissues in the pharynx.

19
Q

Crowing

A

Is a sound like a crow cawing that occurs when the muscles around the larynx spasm and narrow the opening into the trachea.

20
Q

Gurgling

A

A sound like gargling, usually indicates the presence of blood, vomitus, secretions, or other liquid in the airway.

21
Q

Stridor

A

Is a harsh, high-pitched sound heard during inspiration.
