Answer:
Left ventricle
Explanation:
Left ventricle forms the thickest chamber of the heart and receives oxygenated blood from the right atrium. The oxygenated blood from the left ventricle is passed through the aortic valve into the ascending aorta. The blood from ascending aorta passes to coronary arteries, arch of the aorta and descending aorta. Branches of the arch of the aorta and descending aorta deliver the oxygenated blood to the various cells and tissues present in body parts.
