- Excretion
- Carbon Dioxide
- Produced as a waste product of aerobic respiration
- How is it excreted?
- CO2 from respiring cells
- Hydrogen Carbonate ions in blood
- Blood capillaries surrounding the lungs
- Alveoli
- Environment
- Alveoli
- Blood capillaries surrounding the lungs
- Hydrogen Carbonate ions in blood
- CO2 from respiring cells
- Why is it necessary to excrete it?
- Combines with HB to form Carbamino-Hb
- Lower affinity for O2 than normal Hb
- Less O2 can be transported to respiring cells
- H ions combine with HB
- Lower affinity for O2 than normal Hb
- When Hydrogen-Carbonate ions form, Hydrogen ions form
- H ions combine with HB
- CO2 dissolves in blood and forms Carbonic Acid
- Carbonic Acid dissociates
- pH of blood drops (becomes more acidic)
- Respiratory Acidosis
- Symptoms?
- Headache
- Difficulty breathing
- Drowsiness
- Tremor
- Confusion
