A polypeptide with iron that bind to oxygen
High oxygen level, -> combines with RBC
in blood -> leaves
Carbon Dioxide transportation
with help from
Can be dissociated by hemoglobin to create bicarbonate ions and hydrogen
O + CO
Maintains and Detects changes in Gas levels and Blood pH level.
-> Breathing is controlled by CO
: Increased cellular respiration and high elevations
Enzyme responsible for the conversion of carbon dioxide gas into Bicarbonate (common form of CO
in the blood stream)
To ensure oxygen is brought to each call in the body and that carbon dioxide leaves each cell and is removed from the body.
-> Respiratory surface area
-> Moist environment
Stages of respiration
: Involves inspiration(In) and expiration(Out)
: Exchange of oxygen and carbon dioxide between the air and the blood, the lung alveoli.
: The exchange of oxygen and carbon dioxide in the body's cell tissues and blood.
: Series of energy (ATP) releasing chemical reactions that take place inside of cells. The final stage of restoration provides the energy for all cellular activities.
Tiny air sacs in your lungs and blood that exchange oxygen and carbon dioxide during the process of breathing in and breathing out.
Lined with ciliated cells and cells that secrete mucus to warm, moisten, and clean incoming air
Gas moves from areas of high pressure to low pressure.
- Intercoastal muscles
Daltons law of partiall pressure
Gases move from an area of high concentration/pressure to lower concentration/ pressure
Intercoastal muscles and diaphram contract
Rib cage moves upward and outward
Thoratic cavity volume increases which decreases the pressure inside the cavity and air moves inwards
Begins when intercoastal muscles and diaphram relax.
Rib cage falls back to normal position and diaphragm moves upward returning to its done shape.
Thoratic cavity volume decrease and air moves outwards.
Extended respiration takes place in the lungs. Gases are exchanged between the alveoli and the blood in the capillaries.
- Moves oxygen into capillaries
- Moves CO
out of capillaries
Where does air travel?
Nasal cavity -> Pharynx -> Epiglottis -> Larynx(voice box) -> Trachea -> Bronchus -> Bronchioli -> Alveous (alveoli)
Takes place in the lungs, where gases are exchanged between alveoli and the blood in the capillaries.
