The heart is described as superior to the diaphragm because it isa. in back of the diaphragm.b. in front of the diaphragm.c. above the diaphragm.d. below the diaphragm.
Place the following structures in order, tracing the blood flow from the superior vena cava to the heart, to the pulmonary
circulation, and out of the heart to the systemic circulation. Start with superior vena cava as number 1.
aorta
pulmonary capillaries
right atrium
right ventricle
pulmonary arteries
pulmonary trunk
pulmonary valve
pulmonary veins
superior vena cava
tricuspid valve
aortic valve
bicuspid valve
left atrium
left ventricle
Put the flow of blood through the heart in the right order starting with vena cava.
Vena cava
Right atrium
Aortal semilunar valve
Pulmonary veins
Right AV valve
Left Ventricle
Pulmonary arteries
Lungs
Left atrium

- If the left side of the heart fails, then __________________________ Group of answer choices 1)the heart is unable to move blood from the pulmonary circuit to the systemic circuit at the rate needed. This would result in the back up of blood in the lower legs with resulting edema 2)the heart is unable to move blood from the systemic circuit to the pulmonary circuit at the rate needed. This would result in the back up of blood in the aorta. 3)blood would not back up at all, but rather pressure would increase in the left ventricle. 4)the heart is unable to move blood from the pulmonary circuit to the systemic circuit at the rate needed. This would result in the back up of blood in the pulmonary circuit.arrow_forwardDiastole 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…arrow_forwardOne of the following is a life-threatening arrhythmia and an absolute emergency that should immediately be notified by the MA to the physician in the event it appears in the EKG strips.
