Step by step
Solved in 2 steps
- 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.What is the function of the heart? Explain.Why is the left side of the heart larger than the right?
- Which of the following statements regarding heart valves is NOT true? a) They are flaplike structures. Ob) There are four valves in the heart. Oc) They prevent backflow of blood. d) They must remain tightly closed in order to work properly.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 valveWhat is the correct sequence for flow of blood in the heart? o Superior vena cava → right ventricle > right atrium o Pulmonary vein > left atrium → bicuspid valve o Right atrium → mitral valve → right ventricle o Inferior vena cava > left atrium > left ventricle o Right ventricle > aortic semilunar valve → aorta
- What is the role of one-way valves in the return of blood to the heart?Under the microscope, I can see a section through one of the chambers of the heart. The myocardium is thick and the endocardium is very thin. In addition, I can see a valve that connects this chamber to the next which has two cusps that prevent backflow from one chamber into another 4. Where in the heart am 1? What does the thickness of the myocardium tell you about this region of the heart? What is the valve called? What does it do? What other valve would you see in this area of the heart? Where is it situated?How can you distinguish the left and right sides of the heart based on your views of the myocardium of the left and right ventricle?
- Can you describe how blood moves through all parts of the heart?We analyzed the difference between the action potential of a cardiac contractile cell and an action potential in a neuron. Describe the physiological mechanisms behind the primary difference in the shape of these two action potentials. Why is this feature important to the normal workings of the heart?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?
