a.

Summary Introduction

To define: The term “perfusion” and explain its significance in relation to cardiovascular physiology.

Introduction: Living organisms needs different systems that are properly functioning for a healthy living. Cardiovascular system is one such very important system that is required by living organisms. Defects in any part of the cardiovascular system can cause different types of disease.

b.

Summary Introduction

To define: The term “colloid osmotic pressure” and explain its significance in relation to cardiovascular physiology.

Introduction: Cardiovascular is one of the most important systems in humans. Comprised of heart, blood, and blood vessels, this system is important for transport of oxygen and other nutrients to all the cells in the body.

c.

Summary Introduction

To define: The term “vasoconstriction” and explain its significance in relation to cardiovascular physiology.

Introduction: Cardiovascular system is important for transport of different nutrients through the body. blood carries oxygen and other nutrients to different cells in the body. changes or improper functioning of any part of cardiovascular system causes different health issues.

d.

Summary Introduction

To define: The term “angiogenesis” and explain its significance in relation to cardiovascular physiology.

Introduction:  Cardiovascular system comprises of solid functioning heart along with liquid connective tissue called blood. Hormones, oxygen and other important nutrients are transported to every cell of the body through the cardiovascular system.

e.

Summary Introduction

To define: The term “metarterioles” and explain its significance in relation to cardiovascular physiology.

Introduction: The cardiovascular system includes blood, blood vessels, and heart. the most important function of cardiovascular system is transportation of important gases such as oxygen and hormones along with nutrients throughout the body.

f.

Summary Introduction

To define: The term “pericytes” and explain its significance in relation to cardiovascular physiology.

Introduction:. Transportation of gases like oxygen and hormones is done by the cardiovascuklar system. The cardiovascular system is made up of the blood, blood vessels, and the heart. this system also collects waste material from all over the body and filters it in the kidneys.

which of the following mechanisms contributes most to the deterioration of myocardial perfusion in patients with a progressively dilating left ventricle and a cycle of gradual decompensation. A. decreasing left ventricular radius  B. decreasing peripheral  vascular resistance C. decreasing vestibular pressure D.  increasing left ventricular wall tension E. increasing left ventricular wall thickness
Characterize the following into: A. Factors that increase blood pressureB. Factors that decrease pressure 1. Decreased arterial diameter 2. Increased total vessel length 3. Increased vessel elasticity 4. Decreased plasma epinephrine 5. Decreased blood volume 6. Decreased plasma angiotensin 7. Increased stroke volume 8. Increased plasma ADH 9. Decreased blood viscosity 10. Increased parasympathetic stimulation
It is generally accepted that a relatively low diastolic vascular pressure is more important than a relatively low systolic vascular pressure because:   A. diastolic vascular pressure is the pressure that determines the length of diastole. B. diastolic vascular pressure directly determines stroke volume. C. diastolic vascular pressure ultimately determines and controls contractility. D. diastolic vascular pressure is a force the heart must compete              with to open the  aortic valve.
