What are the waste products of respiration in animals?
The waste products of respiration include carbon dioxide and heat.
Why is carbon dioxide dangerous to living tissue?
Carbon dioxide increases the acidity of fluids, which can affect other reactions in the body.
How is carbon dioxide removed from the body in humans?
Carbon dioxide is transported in the blood to the lungs and removed from the lungs during exhalation.
What happens to some of the energy produced during respiration?
Some of the energy is converted into heat energy, which increases the body’s temperature.
Why is it important to remove excess heat from the body?
Excess heat must be removed because high temperatures can denature enzymes, stopping essential reactions.
How is excess heat lost from the body?
Excess heat is lost through the skin.
What happens to excretory products of respiration during exercise?
During exercise, the rate of respiration increases, producing more carbon dioxide and heat. Breathing rate increases to expel excess carbon dioxide, and sweating occurs to remove excess heat.
How does the body remove metabolic waste in urine?
Metabolic waste is excreted in urine, which is removed from the body through the urethra.
