Which chamber of the heart receives oxygenated blood from the lungs?
Answer: Left atrium
The left atrium receives oxygen-rich blood from the pulmonary veins coming from the lungs.
What is the function of the sinoatrial (SA) node?
Answer: Acts as the heart’s pacemaker
The SA node is the heart’s natural pacemaker, initiating electrical impulses that cause the heart to beat.
Which valve prevents backflow of blood into the left atrium?
Answer: Mitral valve
The mitral valve (also known as the bicuspid valve) prevents blood from flowing back into the left atrium when the left ventricle contracts.
What structure separates the left and right sides of the heart?
Answer: Septum
The septum is a muscular wall that separates the left and right sides of the heart to prevent the mixing of oxygenated and deoxygenated blood.
Which vessel carries deoxygenated blood to the lungs?
Answer: Pulmonary artery
The pulmonary artery is the only artery in the body that carries deoxygenated blood, transporting it from the right ventricle to the lungs.
Which layer of the heart is responsible for contraction?
Answer: Myocardium
The myocardium is the thick, muscular middle layer of the heart wall responsible for contracting and pumping blood.
