UNIT 1 ' 1 - BSCADRIC e 1DI0BIR3 5 High pressure in the systemic and pulmonary circuits often results in ventricular hypertrophy, in which the ventricle enlarges to pump against greater force. Which side(s) of the heart would be affected by high pressure in the pulmonary circuit? Which side(s) of the heart would be affected by high pressure in the systemic circuit?

During the exam, she explained that over the last two weeks, she had been feeling much more tired than normal and occasionally felt short of breath. Knowing that women usually present with atypical symptoms of a heart attack, her physician ran some diagnostic tests and found that Ms. F. was indeed having a heart attack. Imaging studies showed that Ms. F. had blockages in her anterior interventricular artery. What parts of the heart would be affected by these blockages?

If the statement is false, correct it to make it a true statement. F a. The three major circuits of blood flow in the body are the systemic, cerebral, and pulmonary circuits F b. The external carotid arteries and vertebral arteries supply blood to the brain T . The cerebral arterial circle provides alternate routes of blood flow through the brain F d. Venous blood from the spleen, digestive tract, and pancreas drains into the inferior vena cava 8 The venous blood of the brain drains into a set of before draining into a vein. a. coronary arteries cerebral veins b . @ dural sinuses d. paranasal sinuses Cardiovascular System = unir 11 = 325

11 Ablood clot that forms along the wall of a blood vessel is called a thrombus. An embolus is a piece of a thrombus that breaks off and flows through the blood until it gets stuck in a small blood vessel downstream from the original thrombus thway an emt C 1 take If it broke off from a thrombus in the external iliac artery (assume it gets stuck q Femoval, poplitenl, antevior Hbiol, formol pedulus, arderiles, CL\(MHNW beds reaches capillary beds) the pathway an embolus could take if it broke off from a thrombus in the femoral vein (assume it gets stuck in es, before it reaches capillary beds) Femorm| vein, external ilioc, common ilioc, wkerior vero cou, right orium, rignt ventricle, Pulnon Trunk, pulmo afi%eq, ?u\wwwan\ ovteroles (mj ij 12 David has an ultrasound of his common carotid arteries, which shows that his right common carotid artery is nearly 90 percent blocked.
