Movement and Exchange of Gas in Human Body

Exchange of gas happens at

• Alvioli

• Bronchus

• Trachea

• Body cells

Inhale air has high concentration of

• Oxygen

• Carbon dioxide

• Oxyhaemoglobin

• Blood

Oxyhaemoglobin form from combination of

• Haemoglobin

• Oxygen

• Glucose

• Water

Blood with oxyhaemoglobin is transported from lungs to

• Other parts of body

• Brain

• Heart

• Spinal cord

Why does oxyhaemoglobin decompose at body cells?

• Being partial pressure

• Being unstable

• Producing energy

• Producing glucose

Process diffusion of oxygen oxidises glucose into Carbon dioxide known as

• Cellular respiration

• Gas diffusion

• Oxyhaemoglobin

• Exhalation
