 There is a blood vessel that has the following characteristics when examined under a microscope: Simple squamous epithelium in the layer next to the lumen Athin tunica media layer Thick elastic connective tissue on the outer layer of the vessel Overall shape is a large collapsed circle What type of blood vessel is this? vein artery capillary arteriole 2. A 65 year old male, who is obese, has a blood pressure reading of 160/100. Answer the following questions about this patient: 0 Calculate the patient's pulse pressure 0 Calculate the patient's mean arterial pressure (MAP) 0 If normal mean arterial pressure is between 70-100mmHg, what does the MAP tell you about her cardiovascular risk? 0 If the patient has this reading (or similar) on more than three different occasions, but no other test are done, what diagnosis would you consider giving them? 3. If a person has hypertension, they will have decreased afterload, which will cause an increased stroke volume. True False 4. In a low blood pressure situation, which of the following is CORRECT? The renin—angiotensin—aldosterone pathway is activated to raise systemic blood pressure. The renin-angiotensin-aldosterone pathway is inhibited to raise systemic blood pressure. The sympathetic nervous system is activated to stimulate vasodilation. The vasomotor center is inhibited so that vasoconstriction can occur and blood pressure is raised. 5. Which of the following people would have increased resistance in their blood vessels due to their condition? An athlete who did blood doping A person with hemophilia Achild who has a heart murmur All of these are correct.

6. An obese patient comes to the clinic complaining of swollen feet and ankles, fatigue, shortness of breath, and often feeling "spaced out." She is a cashier in a grocery store, a job that requires her to stand all day. Outside of work, she engages in no physical activity. She confesses that, because of her weight, she finds even walking uncomfortable. Explain how the skeletal muscle pump might play a role in this patient's signs and symptoms. 7. Match the organ/structure in the body with the type of capillary that would be present there. dermis of skin [ Choose ] sinusoid capillary fenenstrated capillary continuous capillary -liver [ Choose ] sinusoid capillary fenenstrated capillary continuous capillary pancreas [ Choose ] sinusoid capillary fenenstrated capillary continuous capillary -skeletal muscle (i.e. rectus femoris) [ Choose ] sinusoid capillary fenenstrated capillary continuous capillary 8. When measuring blood pressure the systolic number is the first sound you hear when the brachial artery opens from a closed state and the diastolic number is the last sound you hear when the artery is fully opened. True False 9. Blood coming from the arteriole side of a capillary bed will have higher oncotic pressure causing the plasma to leave the capillaries to the tissues. This allows tissues to receive nutrients and oxygen from the blood. True False
