    Study Notes

    Vascular Pathology and Circulatory System

    • The two principal mechanisms responsible for vascular pathology resulting in disease are weakening of vessel walls and complete obstruction of vessel lumens.
    • The circulatory system function involves delivering oxygen and nutrients to tissues while carrying away metabolic waste products.
    • The three major causes of morbidity and mortality mentioned in the text are cardiovascular disease, atherosclerosis, and hypertension.
    • Edema is characterized by an abnormal accumulation of fluid in the interstitial space, leading to tissue swelling.
    • A general cause of edema is increased permeability of vessel walls.
    • Pitting edema is typically caused by increased pressure within the vessel.
    • Lymphatic filariasis, also known as elephantiasis, is caused by the parasitic worm Wuchereria bancrofti.
    • Congestive heart failure is characterized by edema due to increased pressure in the venous system.
    • Nephrotic syndrome is characterized by edema due to increased permeability of vessel walls and loss of proteins in the urine.
    • Lymphedema is characterized by an abnormal accumulation of fluid in the interstitial space, leading to tissue swelling.
    • Thrombosis is the term for the formation or presence of a blood clot within a blood vessel, obstructing the flow of blood.
    • Atherosclerosis is a major cause of morbidity and mortality associated with vascular disorders.
    • Cardiovascular disease is responsible for more morbidity and mortality than any other category of human diseases.

    Cardiovascular System Disorders

    • Cardiovascular system disorders are the major cause of morbidity and mortality.
    • The normal function associated with a healthy circulatory system is delivering oxygen and nutrients to tissues while carrying away metabolic waste products.
    • Vascular pathology results in disease via weakening of vessel walls and complete obstruction of vessel lumens.
