Why is it not lethal for amphibians to mix oxygenated and deoxygenated blood in their three chambered heart a b C d Amphibians can respire though their skin which helps oxygenate the mixed blood Amphibians use gills to oxygenate their blood from their environment directly Amphibians heartbeats prevent mixing of oxygenated and oxygenated blood by pushing blood through the pulmonary circulation first then to the systemic circulation before blood is returned to the heart Amphibians do not mix their oxygenated and deoxygenated blood

What vessels carry deoxygenated blood away from the heart Coronary arteries only Pulmonary artery only Both pulmonary arteries and coronary arteries Neither the pulmonary arteries or coronary arteries

At what location s does CO2 and O2 exchange take place Check all that apply The right side of the heart only The lungs The capillaries The heart
