S
THE CARDIOVASCULAR SYSTEM: BLOOD VESSELS AND CIRCULATION
SECTION OBJECTIVE
1. Compare and contrast the anatomical structure of arteries, arterioles, capillaries, venules, and veins
2. Accurately describe the forces that account for capillary exchange
3. List the major factors affecting blood flow, blood pressure, and resistance
4. Describe how blood flow, blood pressure, and resistance interrelate
5. Discuss how the neural and endocrine mechanisms maintain homeostasis within the blood vessels
6. Describe the interaction of the cardiovascular system with other body systems
7. Label the major blood vessels of the pulmonary and systemic circulations
8. Identify and describe the hepatic portal system
9. Describe the development of blood vessels and fetal circulation
10. Compare fetal circulation to that of an individual after birth
STUDY QUESTIONS
1. You measure a patient’s blood pressure at 130/85. Calculate the patient’s pulse pressure and mean arterial pressure. Determine whether each pressure is low, normal, or high?
2. A patient arrives at the emergency department with dangerously low blood pres- sure. The patient’s blood colloid osmotic pressure is normal. How would you expect this situation to affect the patient’s net filtration pressure?
3. The hepatic portal system delivers blood from the diges.ive organs to the ___.
4. In the renin-angiotensin-aldosterone mechanism ______________.
5. 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 tha requires her to stand all day. Outside of work, she en- gages 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.
6. Cocaine use causes vasoconstriction. Is this likely to increase or decrease blood pressure, and why?
