- which body system supplies cells with oxygen and nutrients and car- ries away waste?
circulatory system
- the pericardial cavity contains the: heart
- which layer of heart anchors it to the pericardium diaphragm?
- what is the purpose of the fossa ovalis in a fetus
It allows fetal blood to move directly from right to left atrium, bypassing he undeveloped lungs. The fossa ovalis closes during birth so that the lungs can receive oxygen once the baby is born.
- label the figure below A-E A- aorta B-right ventricle C-mitral/bicuspid/left AV valve D-left atrium E-pulmonary trunk
- Name the vessel in the figure below: right coronary artery (highlighted in blue, also indicated by the arrow)
- Name the vessel in the figure below: left coronary artery (highlighted in blue, also indicated by the arrow)
- Name the vessel in the figure below: posterior intraventricular artery (highlighted in blue, also indicated by the arrow)
- T/F: arteries have high amounts of stretch with little recoil
false (veins)
- which vessels would you expect to be common carotid, subclavian artery the best place to feel a strong pulse?
- which is the correct order of blood flow starting from the heart?
- which layer of a vessel helps anchor it to surrounding structures?
- The left and right veins carry blood directly into the superior vena cava.
- artery
- arteriole
- capillary
- venule
- vein
tunica externa
brachiocephalic
oxygenated blood is pumped from the heart through the to the rest of the body
- the pacemaker of the heart is the: SA node
- you are reviewing your patients re- sults from an EKG. the findings indi- cate a problem with ventricular de- polarization. where should you look on the EKG to find the abnormal ry- thm?
QRS complex
- Your patient's EKG results indicate dif-purkinje fibers ficulty with left and right ventricular systole. What part of the conduction system is not functioning properly?
- Which statement is true concerning the cardiac cycle
- a patient is suspected to have pul- monary edema due to CHF. Which
A and B, the dub sound is heard when the semilunar valves close and the lub sound is heard when the atrioventricular valves close/ OR the ventricular con- traction time is longer than the atrial contraction time
the left side of the heart would be in failure. if the left side of the heart cannot pump blood out to the body side of the heart would be in failure? tissues eflciently, blood and fluid will back up into the lungs
- a patient has a diagnosis of right sided CHF. which of the following signs/ symptoms would they most likely present with?
swollen ankles
- a patient is admitted to the ER with a myocardial infarction. what signs symptoms would they display?
- your patient has a dx of atheroscle-
all of the above (SOB, angina, heartburn, chest pres- sure)
yes. atherosclerosis is an accumulation of soft masses rosis. would you expect them to also of fatty materials, often cholesterol, inside arteries. have hypertension? why or why not
- your patient is admitted to the hos- pital for coronary artery bypass. ex-
these deposits called plaque accumulate beneath the inner linings of arteries. as plaque continues to build up it tends to protrude into the vessel, interfering with normal blood flow
a segment of another blood vessel from the patient's body will be stitched to one end of the aorta and plain what is going to happen in this the other end to a coronary artery past the point of surgery.
- the heart is contained in the cavity
obstruction. once the heart is exposed, some MDs may also use lasers to open clogged coronary vessels
pericardial
- Name the vessel in the figure below: circumflex branch (highlighted in blue, also indicated by the arrow)
- the aortic arch turns to be come the ?
descending aorta
- what is the name of the artery in the anterior communicating artery figure below (in blue also indicated by the arrow?
a patient has a dx of left sided heart failure. which s/sx would they most likely present with?
- a patient is admitted to the ER with a thromboembolism. Your patient is given t-PA. why?
to help dissolve blood clots
- your patient has a dx of atherosclero- higher risk. thromboembolism is an embolus that be- sis. are they at a higher or lower list of thromboembolism?
- the circulatory system is responsible for which of the following functions
- what is the purpose of the mitral valve?
comes lodged in a vessel as it travels. atherosclerosis is an accumulation of soft masses of fatty materi- als, often cholesterol, inside arteries. these deposits called plaque accumulate beneath the inner linings of the arteries. plaque can cause a clot to form on the irregular arterial wall. if the clot becomes dislodged it can travel and clog a similar artery in its path.
-supply cells with oxygen -transportation of gasses -rid cells of waste -prevents blood loss (all of the above)
The mitral valve (bicuspid) controls the flow of blood from the left atrium into the left ventricle.
- label the figure below A- E A: Superior Vena Cava B: Right Atrium C: Tricuspid/Right AV valve D: Left ventricle E. Pulmonary Valve
- T/F: the cell portion of blood is called true formed elements
- you are reviewing your patient's re- sults from an EKG. the findings indi- cate a problem with ventricular repo- larization. where should you look on the EKG to find this abnormal rythm?
T wave
- list the electrical impulse pathway of -SA Node the cardiac cycle, starting with the pacemaker
- a patient is suspected to have pe- ripheral edema due to heart failure. which side of the heart would be in failure?
- your patient is admitted to the hos- pital for an angioplasty. explain the procedure.
-AV Node -Bundle of HIS -purkinje Fibers
the right side would be in failure. if the right side of the heart cannot pump blood into the heart eflciently, blood and fluid will back up into the veins, causing swelling in body tissues
a surgeon threads a plastic tube into the artery of an arm or leg. the tube is then guided through the blood vessel toward the heart. when the tube reaches the segment clogged by plaque in a coronary artery, the balloon attached to the end of the tube is inflated, forcing the vessel open
- myocardium
