- Figure 40.11 Which of the following statements about the heart is false? The mitral valve separates the left ventricle from the left atrium. Blood travels through the bicuspid valve to the left atrium. Both the aortic and the pulmonary valves are semilunar valves. The mitral valve is an atrioventricular valve.Which statement has a false sentence? The systematic system receives blood from the left ventricle. The first blood vessel in the systematic circuit is the aorta. The pulmonary circulation transports blood from the heart to the lungs and back from the heart. The right side of the heart is the pump for the pulmonary circuit. The coronary circulation is part of the pulmonary circuitWhich heart chambers are used as route between heart and the entire body? right atrium, right ventricle left ventricle, right atrium right ventricle, left atrium left atrium, left ventricle
- I receive blood coming back to the heart from the systemic circuit. What am I? _____________ My job is to prevent the back flow of blood from the left ventricle to the right atrium when the ventricles contract. What am I? _____________ My job is to prevent the back flow of blood from the aorta to the left ventricle when the ventricles relax.What am I? ___________ I return blood from the myocardium to the right atrium. What am I? ___________ I am the pump for the pulmonary circuit. What am I? ____________ I am the pump for the systemic circuit. What am I? ____________ Word Options for Blank: aorta aortic valve bicuspid valve coronary sinus inferior vena cava left atrium left ventricle pulmonary arteries pulmonary trunk pulmonary valve pulmonary veins right atrium right ventricle superior vena cava tricuspid valveWhich chamber of human heart pumps fully oxygenated blood to aorta and hence to the body? A. Right AuricleB. Left AuricleC. Right VentricleD. Left VentricleWhat does each side of your heart do? Draw a picture and explain how the heart functions. Ensure you label each part. In your drawing place arrows indicating the flow of blood through the heart.
- Which row shows the chambers of the heart, from those with the thickest walls to those with the thinnest walls? thickest thinnest A atria left ventricle right ventricle B atria right ventricle left ventricle left ventricle right ventricle atria right ventricle left ventricle D atria C В D O AChoose all the statements that are correct. When the heart beats, first the right side of the heart contracts, and then the left side of the heart contracts. That is one heartbeat. The sympathetic nervous system speeds up the heart rate and the parasympathetic system slows down heart rate. M Bradycardia is when the heart beats faster than normal. The SA node is the pacemaker of the heart. Coronary arteries deliver blood to the muscle of the heart. A heart attack is a myocardial infarction. The ECG (EKG) has a QRS wave that represents ventricular depolarization (the message to tell the ventricle to contract. The heart needs nerve stimulation in order to contract.Complete the table below to summarize what you know about the major vessels of the heart. Vessel Blood Flow in Relation to the Heart: Blood Oxygenation: Entering / Exiting / Within Oxygenated / Deoxygenated Aorta Coronary arteries Pulmonary arteries Pulmonary veins Vena cavae (superior and inferior)
- The heart has its own built-in pacemaker that generates a basic rhythm (heart rate) that the sympathetic and parasympathetic nervous system can change. What is the name of this pacemaker region and where does it sit in the heart?Structure of the Heart Use this table as a checklist for your study of the heart.

Do you enter a heart chamber or a vessel? What is the name of the location (chamber or vessel)?
