Topic 3: Metabolic Rate Flashcards
How can metabolic rate be compared?
Oxygen consumption, carbon dioxide production and heat production
Metabolic rate can be measured using what?
Respirometer, oxygen probes, carbon dioxide probes and calorimeters
What do organisms with high metabolic rate require?
More efficient delivery of oxygen to cells
Birds and mammals have a ________ which is higher the reptiles and amphibians?
Metabolic rate
Reptiles and and Fabians have a higher ___ what than fish?
Metabolic rate
What type of circulatory system to birds and mammals have?
complete double circulatory system
What type of circulatory system to amphibians and most reptiles have?
Incomplete double circulatory system
I’m in complete circulatory system consists of what?
Two atria and one ventricle
What type of circulatory system to fish have?
Single circulatory system
A single circulatory system consists of what?
One atrium and ventricle
What happens to the oxygenated and deoxygenated blood in a complete double circulatory system?
No mixing of oxygenated and deoxygenated blood occurs therefore oxygenated blood can be pumped out at higher pressure enabling a more efficient oxygen delivery to cells
