INTRODUCTION
All living-beings on Earth need energy in order to live, grow and reproduce themselves. The energy they use is generated in a process called respiration.
Methods of respiration by which energy can be obtained.
Anaerobic respiration. Tape-worm.
Aerobic respiration: the presence of oxygen is needed in order to obtain energy.
AEROBIC RESPIRATION
What is respiration?
Mitochrondias. Photosynthesis.
Oxygen found in water used for respiration comes from the atmosphere and photosynthesis which is carried out by aquatic organisms themselves.
RESPIRATION TRACTS
Plants have the ability to produce organic compounds called carbohydrates together with a gas called oxygen.
Photosynthesis and the energy coming from sunlight.
Protozoa breathe through their cellular membranes.
Earthworms use cutaneous respiration.
Amphibians have two kinds of respiration.
More complex animals need more oxygen.
Branchia help to exchange gases.
Some arthropoda have developed tracheal respiration.
Adult amphibious, reptiles, birds and mammals have lungs. How lungs work.
HUMAN RESPIRATION
Man has a respiratory apparatus made of lungs and organs which connect them to the air.
How human beings breathe: the trachea, the lungs, the bronchia, the alveoli.
Capacity of the lungs.
Breathing in, breathing out.
