Human Breathing/ Respiration - Coggle Diagram
Human Breathing/ Respiration
Breathing:
Taking in oxygen and releasing carbon dioxide via the lungs. Breathing plays an important role in homeostasis
Respiration:
using the oxygen that has been inhaled in breathing to release energy from food during aerobic respiration
Lungs
Are air tight
Located in thoracic cavity
Protected by rib cage and sternum
Pleural membrane around lungs allows for friction-free movement
Nose/Nasal Passage:
lined with cilia (hair structures) and mucus to trap dust particles
Epiglottis:
flap of tissue at top of trachea to seal over trachea during eating (to prevent food going down the wrong way)
Trachea:
part of air way passage.
Allows air to enter the lungs.
Trachea is lined with rings of cartilage to prevent collapse of the trachea
Bronchus:
trachea divides into two bronchus;
one leading into each lung
Bronchioles:
bronchus divides into smaller branches known as bronchioles.
Located at the end of the bronchioles are alveoli
Pleural Membrane:
acts as a lubricant and reduces friction
Alveoli:
point of gaseous exchange where gases (O2 and CO2) are exchanged between the lungs and blood.
Alveoli have adapted to their role in gaseous exchange by
Presence of many alveoli increase large surface area
WALLS are one cell thick (allow for faster movement of molecules)
Moist surface (gases can only travel dissolved in water)
Surrounded by a good blood supply
