    Assertion Left ventricle of heart has a thinner wall than that of right ventricle. Reason Left ventricle eeds to pump blood to nearby lungs only.

    Contraction of the ventricle in the heart begins by the command from

    Assertion : The left ventricle of heart has a thinner wall than that of the right ventricle. Reasoning : the left ventricle needs to pump blood to nearby lungs only.

    Read the statements and select the option which best describes the process that occurs during systemic circulation. (i) The left atrium receives the oxygenated blood through the pulmonary veins. The left ventricle pumps the blood through the aorta to various parts and the deoxygenated blood reaches right atrium. (ii) The left atrium receives the oxygenated blood through pulmonary veins and pumps the blood through the aorta to various parts and the deoxygenated blood reaches the right atrium. (iii) The left atrium receives deoxygenated blood and pumps into left ventricles which in turn pumps into pulmonary artery for oxygenation. (iv) The right atrium receives the deoxygenated blood and pumps into pulmonary artery for oxygenation.
