Respiratory system
Commonly called the windpipe, this structure is strengthened by rings of cartilage.
trachea
smaller branches from the bronchi that enter the lungs
Bronchioles
This process is the result of air rushing into the lungs
Inhalation
from the air sacs/alveoli, where does the oxygen pass into the blood from which blood vessel?
the capillaries
What is the number one cause of lung disease/damage?
Smoking
These air passages divide from the windpipe at the bottom of the trachea.
bronchi
The voicebox
larynx
This pulls down and causes air to rush into the chest cavity
Diaphragm
Bones that protect the lungs
the Rib cage
This happens when something irritates your nose
Sneeze
What is the name of the large muscle (singular) that pulls air into the lungs?
The diaphragm
Exchange of oxygen and carbon dioxide
respiration
During inhalation what does the diaphragm do?
Contracts
Hollow organ that allows you to talk and make sounds when air moves in and out
the Larynx
Physical activity causes breathing rate to do what?
Increase
What are the tiny hairs that move back and forth along the trachea called?
Cilia
where oxygen and carbon dioxide change places in the lungs
the alveoli/air sacs
In diffusion ( e.g. at the alveoli)...particles move from ____ to ____ concentration
High to low
The part of the respiratory system that is connected to the nose and mouth and is shared with the digestive system.
Pharynx
What is the sticky coating that is secreted by cells along your respiratory tract?
Mucus
What are the tiny balloon-like sacs that look like bunches of grapes where carbon dioxide in the blood is exchanged for oxygen?
Alveoli
What is minute ventilation?
Ventilation is measured as minute ventilation. This is calculated by multiplying the number of breaths you take in a minute (RR) by the amount of air you breathe in or out with each breath (TV).
What is tidal volume
The amount of air that moves in or out of the lungs with each respiratory cycle (inhale and exhale)
What is the main organ of the respiratory system?
Lungs
Name two thing that nose hairs do.
1. Keeps pathogens out of the nose
2. Warms the air going in
