Module 3 - Respiratory System Hw Flashcards
Which lung has 3 lobes?
The Right Lung has 3 lobes.
What is breathing (ventilation)?
Breathing is moving air in and out of the lungs.
What is external respiration?
External Respiration is a gas exchange between air and blood in the lungs.
What is internal respiration?
Internal respiration is a gas exchange between blood and tissues.
What is cellular respiration?
Cellular respiration is using oxygen to produce energy (ATP) and the byproduct is carbon dioxide.
What are some functions of nose & pharynx?
Some functions of the nose and pharynx are that they are a passageway for respiration, receptors for smell, they filter large particles from air, moistens incoming air, warms incoming air, and works as a resonating chamber for voice.
What is the flexible flap of cartilage that routes food and air properly?
The flexible flap of cartilage that routes food and air properly is the Larynx.
What do vocal cords assist in?
The vocal cords assist in sound production.
Where does air go when it travels through the windpipe/trachea?
When air travels through the trachea (windpipe) it travels to the lungs.
The space between pleural membranes (pleural cavity) contains fluid that does what?
The fluid in the space between pleural membranes decreases friction when the lungs move.
What are alveoli?
The alveoli are microscopic air-filled sacs where gas exchange occurs.
Lungs receive deoxygenated blood from __________?
The right ventricle of the heart.
What is tidal volume?
Tidal volume is the volume of air inhaled and exhaled in 1 breath.
What is vital capacity?
Vital capacity is the maximal volume that can be exhaled after maximal inhalation.
What is residual volume?
Residual volume is the volume of air remaining in the lungs even after a forceful maximal expiration.
How is residual volume measured?
Residual volume is measured by a spirometer.
98% of oxygen in blood is carried bound to ___________ molecules in red blood cells?
Hemoglobin.
What results after spasmodic contraction of bronchi?
Asthma results after spasmodic contraction of bronchi.
What disease is an inherited condition where abnormally thick mucus in lungs impedes air flow?
Cystic Fibrosis is an inherited condition where abnormally thick mucus in lungs impedes air flow.
Describe COPD in 2 sentences.
Chronic Obstructive Pulmonary Disease (COPD) is a lung disease known by chronic poor air flow and the person usually has shortness of breath and a cough that produces phlegm. This disease gets worse over time and eventually impedes the person from doing everyday tasks.
