Choose 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.

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 heart chamber has the thickest wall? a. right atrium c. left atrium b. right ventricle d. left ventricle
Which of the following statements is correct? Group of answer choices Veins carry blood away from the heart A stenotic heart valve would restrict the flow of blood through the valve Semilunar valves are located between the atria and the ventricles The right ventricle pumps blood to the systemic circulation
Which of the following statements best describes systolic blood pressure? Systolic blood pressure depends upon the force of the heart contractions - the stronger the contractions the higher the systolic pressure will be. Systolic blood pressure depends on how tightly the cuff of the sphygmomanometer is tightened. Systolic blood pressure depends upon the resistance of the blood vessels - the greater the resistance to blood flow the higher the systolic pressure will be. Systolic blood pressure depends upon the force and frequency of the heart contractions - the stronger and more frequent the contractions the higher the systolic pressure will be.
Which 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
Which of the terms in the following pairs is correctly matched? Group of answer choices Heart contraction : systole Stroke volume : end systolic volume minus end diastolic volume End diastolic volume : volume of blood in the ventricle immediately after it has contracted Passive filling : blood moves into the ventricles because the atria contract
Choose the statement(s) that are correct about serous membranes. Select all that apply. Visceral pericardium covers the surface of the heart, and parietal pericardium lines the interior of the heart. Serous membranes line body cavities that are open to the outside. Serous membranes are very thin, double-layered structures. Serous membranes secrete a watery lubricating fluid.
What happens when the pressure in the ventricles becomes lower than the pressure in the atria? the first heart sound occurs the semilunar valves open the atrioventricular valves open the semilunar valves close
Which of the following statements concerning the heart is true 1. The intraventricular septum prevents the electrical activity from stimulating the heart in a superior to inferir direction 2. The bundle of his is located in the intraventricular septum 3. The bundle branches stimulates the ventricles in ann inferior to superior direction
A person showing signs and symptoms of a heart attack will often: Panic and faint Deny that they are having a heart attack Take a nap to relieve pain None of the above
Outline the flow of the electrical impulse through the conduction system of the heart by choosing the correct sequence from the drop-down menusFill the slots with the terms provided (A) leads to (B) leads to (C) leads to (D) leads to (E) Terms to use: Purkinje fibers SA node AV node and atrial contractile cells Ventricular and contractile cells right and left bundle branches
What 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.
