Question

Name UNIT 11 Quiz continued Section Date 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? Explain. 6 Ms. F. visited her physician for a routine physical. 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 a Imaging studies showed that Ms. F had blockages in her anterior interventricular artery What parts of the heart would be affected by these blockages? b Ms. S heart attack damaged one of her papillary muscles. What is the normal function of a papillary muscle? Predict the consequences of a malfunctioning papillary muscle. 7 True/False: Mark the following statements as true (T) or false (F). If the statement is false, correct it to make it a true statement a. The three major circuits of blood flow in the body are the systemic, cerebral, and pulmonary circuits. b. The external carotid arteries and vertebral arteries supply blood to the brain C. The cerebral arterial circle provides alternate routes of blood flow through the brain. d. Venous blood from the spleen, digestive tract, and pancreas drains into the inferior vena cava. 8 before draining into a vein. The venous blood of the brain drains into a set of a coronary arteries b cerebral veins c. dural sinuses d. paranasal sinuses Sardiovascular System + UNIT 11 325

Answer 1

Hope this is practice quiz.

5.Left ventricle get Hypertrophy or enlarged to pump against grater force.

Due to high pressure in the pulmonary circulation right side of the heart get affected ,Because in pulmonary circulation right atrium receive deoxygenated blood from all body parts and left ventricle pump deoxygenated blood to lungs for purification .

Due to high pressure in the systemic circulation Left side of the heart get affected ,Because in systemic circulation left atrium receive oxygenated blood from lungs through pulmonary vein and left ventricle pump oxygenated blood4to body tissues. So high pressure causes effect.

6. A.Due to blockage in anterior intra ventricular artery Intervenricular septum and thus Bundle brach of conducting system will affect.

6.B.Normal fuction of papillary muscle was contraction during Ventricular contractions to prevent inversion or prolapse Mital and Tricuspid valves. Dysfunction of papillary muscle leads to Regurgitation of mood through valves causing Back flow of blood that can leads to the left or right side heart failure.

7.a.False.correct statement was "There are two Major circuit systems in our body Systemic (coronary)and pulmonary circulation systems.

7.b.true.

7.c.true.

7.d.false .Venous blood of blood drains into Splenic vein and ends as portal vein.

Venous blood of digestive system drains into portal venous system via hepatic veins and enters to inferior vena casa.

Venous blood from pancreas drains into superior mesentric branch of hepatic portal vein and spleninc vein.

8.Venous blood of brain drains into dural sinuses located between two layers of dura mater.
