differentiate between auricle and ventricle
Answers
Answer:
Explanation:
The auricles or atria are the upper chambers of the heart which is classified into left and right atria. The lower chambers the heart are ventricles which consist of left and right ventricles.
Function
Auricles receive deoxygenated blood from the systemic circulation through superior vena cava and inferior vena cava and directed down to the right ventricle through the tricuspid valve which is then sent out from the heart through the pulmonary artery for pulmonary circulation. Ventricles receive oxygenated blood through the mitral valve from the left atrium which then is pumped out through the aorta into systemic circulation.
Chamber Walls
Auricles have thinner walls. Ventricles have comparatively thicker walls to withstand the pressure
