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
Aorta
Mitral valve
Pulmonary semilunar valve
Right ventricle
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.
One 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.

Select one: Flow of blood from atria Closure of semilunar valves Closure of AV valves Contraction of ventricles Contraction of atriaarrow_forwardThe second heart sound is caused by the ventricles contracting opening of the AV valves closing of the semilunar valves closing of the AV valvesarrow_forwardUse an arrow to indicate where DORV would occur on the flow chart (right ventricle to aorta and pulmonary trunk)arrow_forward
- "the patient's heart makes a sound at systole, assuming it is the S1 sound made by closing of valves, which valve are involved?" mitral valve and tricuspid valve pulmonary and aortic valve mitral and pulmonary valve aortic and tricuspid valvearrow_forwardUse an arrow to indicate on the flow chart where DORV would occurarrow_forwardWhat 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/veinsarrow_forward

Question 12 options: Pectinate muscles help open this valve by pulling down on the chordae tendineae This valve closes when pressure in the left ventricle exceeds that of the left atrium The papillary muscles open this valve by pushing on the chordae tendineae This valve opens when pressure in the right atrium exceeds that of the right ventriclearrow_forward
- During the production of the waveform of the EKG indicated by the arrow, blood would pass through which 2 valves of the heart? aortic and pulmonic mitral and tricuspid (c) aortic and mitral pulmonic and tricuspidarrow_forwardDetermine 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.arrow_forwardThe first sound of a cardiac cycle occurs when the _____ and ______ (select them in alphabetical order) are closing. The second sound of a cardicac cycle occurs when the _______ and ________ (select them in alphabetical order) are closing.
