Respiratory System Flashcards
Name the structures that make up the respiratory system beginning where air is taken in and ending where gasses are exchanged in the lungs.
Nose, Pharynx, Larynx, Trachea, Bronchi, Lungs, and Alveoli
Which structure is part of both the respiratory and digestive system
Pharynx
Into which structure do the adenoids, tonsils, and eustachian tubes enter
Pharynx
What type of blood vessels surrounds the alveoli
Pulmonary Capillaries
The voice box is also known as
Larynx
This structure leads directly to the lungs
Bronchi
What molecule is high in concentration when it enters the lungs from the heart
Carbon Dioxide
The lungs are located in this body cavity
Thoracic
The functions of the nasal concha, nose hairs, and mucous membranes is to
Clean and warmed by turbulence
This structure is located at the end of the pharynx
Larynx
This structure prevents choking
Epiglottis
The pharynx located behind the mouth is called
Oropharynx
The pharynx located behind the nose is called
Nasopharynx
This structure separates the thoracic cavity from the abdominal cavity
Diaphram
Name the vessels that enter and exit the lungs going to and from the heart. State whether the blood in these vessels is high or low in oxygen and carbon dioxide when they enter the lungs
Pulmonary Artery - Deoxygenated blood, carries blood away from the heart. High in CO2
Pulmonary veins - Oxygenated blood, carries bloods towards the heart. Low in CO2.
How do the left and right lungs differ
The right has two primary Bronchi and 3 lobes. The left side has one primary bronchi and 2 lobes.
Describe how the diaphragm and intercostal muscles behave during inspirations and expiration.
During inspiration diagram contracts making thoracic cavity longer. The intercostal muscles pull ribs up and out tot elevate the sternum.
During expiration the muscles relax and decreases the size of the thoracic cavity.
Respiratory volume inhaled or exhaled during normal breathing
Tidal Volume
Air in respiratory passages that does not contribute to gas exchange
Dead Space Volume
Total amount of exchangeable air
Vital Capacity
Gas volume that allows gas exchange to go on continuously due to air left in lungs after maximum exhalation
Residual
Amount of air that can still be exhaled (forcibly) after a normal exhalation
Expiratory
Long volumes are found in:
Taller people, high altitudes, and athletes
Short volumes are found in:
Short people, obese, and low altitudes
