Comparing The Walls Of Atria And Ventricles: Structural Differences Influencing Heart Function
The atrial walls are thinner and less muscular than the ventricular walls, reflecting their different roles. Atria receive blood and have relatively weak contractions, while ventricles pump blood out of the heart and have thick, muscular walls for powerful contractions. Additionally, the ventricles’ walls contain trabeculae and papillary muscles, which enhance their contractile strength. Thickness:…
