Peripheral Vascular - Bates Flashcards
What are the three layers of tissue in arteries?
1) intima
2) media
3) adventitia
What does injury to vascular endothelial cells cause?
1) thrombus formation
2) atheromas
3) vascualr lesions of HTN
What are the functions of the arterial intima?
1) synthesizes regulators of thrombus
2) produces prothrombotic molecules
3) synthesizes vasoconstrictors
4) synthesizes vasodilators
5) regulates immune and inflammatroy reactions
What are the functions of the arterial media?
To dilate and constrict blood pressure and flow
What are the functions of the arterial adventitia?
1) connective
2) contains nerve fibers
3) contains the vessels of the vessels
Resistance is _______ proportional to the 4th power power of the vessel diameter.
inversely (Law of LaPlace)
Veins have what two layers?
1) intima
2) media
What is the function of the venous media?
Changes vein caliber in response to minor changes in pressure
What are some problems that veins are susceptible to due to their structure?
1) irregular dilation
2) compression
3) ulceration
4) tumors
What is the normal size of the adult inguinal lymph node?
1-2 cm
Which lymph nodes drain the superficial portions of the lower abdomen and buttock, the external genatalia (except the testes), the anal canal and perianal area, and the lower vagina?
The horizontal group of the superficial inguinal nodes
What is the result of lymphatic dysfunction or disturbances in hydrostatic or osmotic forces of the capillary bed?
Edema
What is the term for pain or cramping in the legs during exertion that is relieved by rest within 10 minutes?
Intermittent claudication
What disease causes spasm of distal arteries in the hands and episodes of sharply demarcated pallor of the fingers?
