OXYGEN - Coggle Diagram
OXYGEN
What is oxygen used for in our bodies?
Cellular respiration: glucose is broken down + oxygen = energy to the cell/ATP = CO2 + H2O get out
There are two types of respiration:
Aerobic respiration:
Uses oxygen
Glucose breaks down
It happens in the Cytosol and Mitochondria
High energy is released
CO2 and H20 get out
Anaerobic respiration:
Doesn't use oxygen
Glucose breaks down
Low energy is released
It happens in the Cytosol
Lacid acid - muscle cells
Plants and fungi have anerobic respiration
Chemical reaction that happens inside every living cell
How does oxygen reaches the organs?
There are two main systems involved:
Circulatory system
Diagram and parts
What it does?
Deliver company used by the organs to transport:
Nutrients
Oxygen
Carbon dioxide
Metabolic wastes
From one part of the body, to another
Deliver nutrients and oxygen to the cells
Pumped blood to all the body
Transport blood though the body
How it does?
Veins carry blood to the heart
Then arteries take blood out of the heart
Which makes that the heart beats or pumps
Respiratory system
Diagram and parts
What it does?
Gets out oxygen from the air into the lungs
Help us to breathe
Gets rid of carbon dioxide
How it does?
Gas exchange
Deoxygenated blood (venus blood) passes trough the blood stream, releasing carbon dioxide
Then the oxygen oxygenate the blood and it gets to other parts of the body
