Respiration Flashcards
What is the chemical reaction of respiration in our cells?
Oxygen + glucose -> water + energy + CO2
How do we know something is alive?
MRS GREN.
What is breathing?
The muscular contraction.
What is the chemical reaction for anaerobic respiration?

Glucose -> lactic acid + energy
What is a positive result of CO2 in limewater?

What do capillaries surround?
The alveoli.
Name five different parts of the lungs.
Trachea Alveoli Diaphragm Left and right bronchi Bronchioles Right and left lobes Pleura Secondary bronchi
Draw a diagram of the lungs.
What is gas exchange?
Where oxygen is picked up in the alveoli and where CO2 is dropped out of the alveoli.
Name three ways the lungs are adapted to gas exchange.
Cilia sweep mucus out of the lungs.
The blood capillaries’ thin walls let substances pass through them.
The alveoli have a large surface area for taking in oxygen and excreting CO2.
Oxygen is diffused into…
…the blood.
