Pathway of blood through the Human Circulatory System Trace the pathway of blood through the circulatory system by placing the parts found on the word box to the appropriate box where it belongs in the diagram. A. Bicuspid Valve B. Aortic Semilunar Valve C. Pulmonary Semilunar Valve D. Tricuspid Valve E. Veins (from venules) F. Artery (to arterioles) G. Aorta H. Pulmonary Artery I. Pulmonary Vein J. Superior Vena Cava K. Inferior Vena Cava L. Veinlet M. Right Atrium N. left Atrium O. Right Ventricle P. Left Ventricle Q. Coronary Sinus

The peripheral chemoreceptors that respond to oxygen levels of the blood and regulate heart activity are located in Select one: a. structures near the carotids and aortic arch. b. the infundibulum of the hypothalamus. c. the left ventricle. d. the right ventricle. e. the medulla oblongata.

Which of the following is not a type of capillary?a. continuousb. sinusoidc. elasticd. fenestrated

Which statement about atrial contraction is true.   A the end diastolic volume is the volume of blood that enters the ventricles during atrial contraction   B the end diastolic volume is the volume of blood in the atria at the end of diastole   C most of the filling of the ventricles occurs during atrial contraction   D when atrial contraction begins the ventricles are already about 80% full

Atrial flutter is characterized by A.  An atrial rate slower than the ventricular rate B.  Waves with a saw tooth or picket fence pattern C.  An atrial rate between 160 and 220 beats per minute D.  All of the above

What are some observations comparing the schematics of the fish and mammal circulatory systems? (Note: these are simplified schematics that don't show every single route for blood, so focus on the heart and the immediate inflow/outflow around the heart.)

for its oxygen then it may die, forming rct. The severity of this condition depends on the precise location of the occlusion, which downstream tissues are involved, and how large an area of tissue dies. Use Figure 4.9 as a reference and list the flow of blood through both circuits in order, beginnng with the right atrium (don't forget to include the heart valves). 1. If an embolus breaks off in a systemic vein in the leg, it would be able to pass through: It would occlude: 2. If an embolus formed in the left ventricle, it would be able to pass through: 3. It would occlude: 4.
