What is the symbol equation for AEROBIC respiration?
C H O + 6O → 6CO + 6H O
1 of 6
What do RED blood cells do?
Carry oxygen around the body
2 of 6
When does ANAEROBIC respiration take place?
During hard exercise when there is insufficient oxygen available.
3 of 6
ANAEROBIC respiration produces LACTIC ACID, which:
Builds up in muscles causing PAIN and FATIGUE. It also acts as an OXYGEN DEBT and has to be broken down in the liver after exercise.
4 of 6
the HEART -
has four chambers and is part of a double circulatory system.
5 of 6
Arteries- THICK elastic walls + carry blood AWAY from the heart
Veins - large LUMENS + VALVES + carry blood back to the heart. CAPPILARIES- permeable and link ARTERIES to VEINS.
