Peripheral Vascular System Flashcards
consists of vessels of body?
Vascular System
tubes for transporting fluid, such as blood or lymph?
Vessels
It forms separate vessel system, which retrieves excess fluid from tissue spaces and returns it to the bloodstream?
Lymphatics
It controls the amount of blood delivered to tissues?
Muscle fibers or VSM (Vascular Smooth Muscle)
It contracts or dilates, which changes the diameter of arteries to control the rate of blood flow?
VSM
Its function is to supply oxygen and essential nutrients to tissues
o Complete blockage leads to death of distal tissue
o Partial blockage creates an insufficient supply, and ischemia may be apparent only at exercise when oxygen needs increase?
ARTERIES
What is the major artery supplying the arm which runs in biceps-triceps furrow of upper arm and surfaces at the antecubital fossa in the elbow medial to biceps tendon?
BRACHIAL ARTERY
Immediately below elbow, brachial artery bifurcates into ulnar and radial
arteries. These run distally and form two arches supplying hand; these are called?
superficial and deep palmar arches
It is a pulse that lies just medial to radius at wrist?
Radial Pulse
It in same relation to the ulna, but it is deeper and often difficult to feel?
Ulnar artery
Major artery to leg is WHAT? It passes under inguinal ligament
FEMORAL ARTERY
Femoral artery travels down thigh; at lower thigh, it courses posteriorly, then is termed?
POPLITEAL ARTERY
Below knee, popliteal artery divides; anterior tibial artery travels down front of
leg on to dorsum of foot, where it becomes?
DORSALIS PEDIS
In back of leg, posterior tibial artery travels down behind medial malleolus and in foot forms?
Plantar arteries
It affects noncoronary vessels and refers to arteries affecting the limbs?
Peripheral arterial disease (PAD)
3 types of veins in legs?
-DEEP VEINS
-Superficial veins
-Dilated and tortuous (varicose) veins
These are great and small saphenous vein?
SUPERFICIAL VEINS
Perforators are connecting veins that join two sets
o Veins drain deoxygenated blood and its waste products from tissues and
return it to heart. o In the legs, this mechanism?
CALF PUMP OR PERIPHERAL HEART
Veins are called _____ vessels because of their ability to stretch?
CAPACITANCE
It form a completely separate vessel system, which retrieves excess
fluid from the tissue spaces and returns it to the bloodstream?
Lymphatics
_______ and ______ lead to increased risk for
venous disease?
Hypercoagulable states and vein wall trauma
The functions of lymphatic system are to?
o Conserve fluid and plasma proteins that leak out of capillaries
Form a major part of immune system that defends body against disease
o Absorb lipids from intestinal tract
Processes of immune system are complicated and not fully understood. Lymphatic vessels have a unique structure
Lymph nodes are small oval clumps of lymphatic tissue located at intervals
along vessels. Superficial groups of nodes are accessible to inspection and palpation giving
clues to status of lymphatic system
GRADING PITTING EDEMA: Very deep pitting, indentation lasts long time, leg very swollen?
4+
GRADING PITTING EDEMA: Deep pitting, indentation remains, leg looks swollen?
3+
GRADING PITTING EDEMA: Mild pitting, slight indentation, no perceptible swelling
1+
GRADING PITTING EDEMA: Moderate pitting, indentation subsides rapidly
2+
