Organs
The main passageway for air into and out of our body
Nose
Function of alveoli
Perform gas exchange in lungs
We inhale this gas
oxygen
Cells use this to break down molecules
Oxygen
This disorder results in a large amount of mucus from irritants
Asthma
Spongelike organs filled with bronchioles and alveoli
Lungs
Purpose of diaphragm
expand and contract chest cavity to allow intake and release of Oxygen and CO2 (breathing)
We exhale this gas
Carbon dioxide
Cells produce these molecules as waste
CO2 and H20
The inflamation of the bronchi/bronchioles
Bronchitis
The passageway for air traveling from the larynx to lungs
Trachea
Purpose of Larynx
Airway--voicebox
This muscle is responsible for voluntary contractions and expansions of the loungs
diaphragm
These three types of molecules are broken down by Oxygen
Carbohydrates, fats and proteins
Caused by bacteria or viruses that inflame and fill lungs with fluids
Pneumonia
One of these goes to each lung and branches into thousands
Bronchus
Purpose of pharynx
entrance of air food water, epiglottis separates two tubes
These branches extend throughout the lungs connecting the windpipe to the alveoli
Bronchioles
How is carbon dioxide exhaled?
It is released by cells into the bloodstream and then reaches the lungs
The unrestricted replication of lung cells
This organ uses muscles to control stretching of cords
Larynx
Purpose of capillaries
thin vessel allows cell movement one at a time to diffuse gasses
The reason we breathe is to provide oxygen to aid in what process
Cellular respiration
How are the cardiovascular and respiratory system related?
Respiratory system brings in Oxygen to supply cells and the cardiovascular system circulates the oxygen via rbcs and hemoglobin
difficulty absorbing oxygen in the lungs due to tissue erosion
Emphysema
