The presence of only one ventricle in the frog's heart causes mixing of oxygenated and deoxygenated blood, making it harder for the body to get the oxygen it needs. This mixing occurs because the single ventricle pumps both types of blood out to the body, which is less efficient compared to the double circulation seen in mammals, where separate ventricles allow for complete separation of oxygenated and deoxygenated blood.
how does the presence of only one ventricle in the frog’s heart affect its circulatory system?(1 point) Responses It allows for complete separation of oxygenated and deoxygenated blood. It allows for complete separation of oxygenated and deoxygenated blood. It causes mixing of oxygenated (blood with oxygen in it) and deoxygenated blood (blood without oxygen in it), making it harder for the body to get the oxygen it needs. It causes mixing of oxygenated (blood with oxygen in it) and deoxygenated blood (blood without oxygen in it), making it harder for the body to get the oxygen it needs. It prevents blood from being pumped to the lungs. It prevents blood from being pumped to the lungs. It enhances the efficiency of oxygenation compared to the human heart
