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.

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.
Outermost layer of the heart as organ itself Composed of skeletal muscle Composed mainly of cardiac muscle tissue Also referred to as the epicardium Area filled with serous fluid to decrease friction Functions to bring air in and out of lungs Outermost portion of sac composed of dense irregular connective tissue Innermost layer of the heart organ Middle layer of the heart organ Most superficial layer secreting serous fluid Entire protective structure surrounding heart Identify location of entrance and exit of blood vessels Tapered end of heart pointing toward left hip Most deep layer secreting serous fluid fills and empties of blood
Choose all the correct statements. The right atrium receives deoxygenated blood from the body cells. Blood in the left ventricle is oxygenated and is sent out through the aorta to all the cells of the body. Blood in the left ventricle is pumped into the pulmonary artery. The superior and inferior vena cava deliver deoxygenated blood to the right atrium. The heart has 2 ventricles and 3 atria. The mitral valve is the tricuspid valve. The surface of the heart is covered by the visceral pericardium. The left side of the heart pumps blood to the lungs.
Describe the flow of blood through the heart from where it returns to the heart through where it leaves to travel to body tissues. Make sure to include all appropriate anatomical structures.
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.
What is the tissue type for the following structures of the heart Fibrous pericardium Serous pericardium Myocardium Endocardium Right atrium right Ventricle Left Atrium Left Ventricle Auricles Papillary muscles Fossa Ovalis Pectinate Muscles Chordae Tendinae Interventricular septum Tricuspid, pulmonary, Bicuspid, mitral, and Aortic semilunar valves pulmonary trunk Pulmonary artery Aorta Arteries Sinus/veins
Determine whether the statement is either true or false. To clearly hear the heart sound of the bicuspid valve, a stethoscope should be placed to the left of the sternum at the second intercostal space. At late diastole, the atria and ventricles are relaxed and the aortic semilunar valve is open. During ventricular contraction all the blood is forced out of the ventricles.
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.
Match the layer or structure to the correct tissue type. myocardium visceral pericardium endocardium parietal pericardium epicardium diaphragm capillary walls the middle portion of artery and vein walls fibrous pericardium Answer choices (used more than once) connective tissue muscle tissue epithelial tissue
Diastole and systole are terms that address the contracting and relaxing of the heart. Which of the following statements about diastolic and systolic blood pressure are true? Select all that apply. The diastolic blood pressure reading is the second number that is read and it's a measurement of the pressure of the arteries as the heart contracts and beats. The systolic blood pressure reading is the first number that is read and it's a measurement of the pressure of the arteries as the heart contracts and beats. The systolic blood pressure reading is the first number that is read and it's a measurement of the pressure in the arteries when the heart rests between beats. Systole refers to when the heart contracts and blood flows from atria into ventricles. The diastolic blood pressure reading is the second number that is read and it's a measurement of the pressure in the arteries when the heart rests between beats Diastole refers to when the heart contracts and the blood flows from the…
