Which body system supplies cells with oxygen and nutrients and carries away waste? Circulatory system The heart is contained in the _______ cavity. Pericardial Which layer of heart anchors it to the diaphragm? Pericardium What is the purpose of the mitral valve? Mitral valve controls the flow of blood from the left atrium into the left ventricle Label the figure below (A-E): A: B: C: D: (In blue) E: A: Superior Vena Cava B: Right Atrium C: Tricuspid Valve/ Right AV valve D: Left Ventricle
E: Pulmonary valve Name the vessel in the figure below: r Right Coronary Artery Name the vessel in the figure below: l Left Coronary Artery
A patient had a stroke in their frontal lobe. What vessel was most likely blocked? Anterior cerebral artery These two arteries of the circle of Willis arise from the common carotid arteries in the neck. Internal carotid arteries (left and right) What is the name of the artery in the figure below? Anterior Communicating artery Use the figure below to answer the following question. Which part of the medical equipment (B-F) is squeezed to inflate A? A. Bladder B. Monometer C. Cuff D. Stethoscope
E. Valve F. The bulb True or False: The cell portion of the blood is called formed elements. True True of False: Hydrostatic pressure is the net pressure which pushes fluid into the tissues. True The average pH of blood is near:
A ______ does not contain a nucleus: Red Blood Cells
The right side of the heart would be in failure because if it cannot pump blood to the efficiently, the blood and fluid will back up into the veins, causing swelling in the body tissues. A patient has a diagnosis of left sided heart failure. Which of the following signs/symptoms would most likely be present with? SOB at rest Swollen ankles All the above A patient is admitted to the ER with a myocardial infarction. What signs/symptoms could they display? SOB Angina pectoris Heart burn Pressure over the chest Your patient has a diagnosis of atherosclerosis. Is your patient at a higher or lower risk for a thromboembolism? Explain your reasoning. Higher risk Atherosclerosis is an accumulation of soft masses of fatty materials in the arteries. A thromboembolism is an embolus that becomes lodged in a vessel as it travels. Plaque can cause a clot to form on the irregular arterial wall. If this clot becomes dislodged it can travel and clog a smaller artery in its path. Your patient is admitted to the hospital for a coronary artery bypass. Use your own words to explain to your patient about what is going to happen in this surgery. During this procedure, the surgeon will take a segment of another blood vessel from the patient's body and stitch one end of the aorta and the other end to a coronary artery past the point of obstruction. Some physicians may also use lasers to open the clogged vessels if the heart is open and exposed.
The circulatory system is responsible for which of the following functions? Supply cells with oxygen Transportation of gases Rid cells of waste Prevents loss of blood What is the purpose of the fossa oval is in the a fetus? It is an opening in the interstitial septum that allows the blood to flow from the right atrium to the left atrium. This bypasses the undeveloped lungs of the fetus True or False: Veins carry blood to towards the heart. True Which layer of a vessel helps anchor it to the surrounding structures? Tunica externa The left and right ______ veins carry blood directly into the superior vena cava Brachiocephalic A patient had a stroke in their pons portion of the brain stem. What vessel was most likely blocked? Basilar artery
Left sided because pulmonary edema effects the left side, and the flow of oxygenated blood from the heart would be compromised. True or False: Arteries have high amounts of stretch with little recoil. False What is the name of the artery in the figure below (in blue also indicated by the arrow)? Posterior Cerebral artery True of False: Osmotic pressure is the net pressure which pushes fluid into the tissues. False A patient has a diagnosis of right sided heart failure. Which of the following signs/symptoms would they most likely present with? Swollen ankles
