W6 Lymphatic System Flashcards
what’s the function of the peripheral vascular system
transport of blood
contains system of the arteries veins and capillary
which 2 vessels drain
veins and lympathics
what’s the Functions of the Peripheral Vascular System
transport blood
host system of veins arteries and capillaries
which 2 vessels drain
veins and lympathics
what’s the organisation of the PVS
Head & Neck
Upper Limbs
Thorax
Abdomen
Pelvis
Lower Limbs
what do arteries have that veins dont
branches
what do veins have that arteries dont
tributaries
what are the capillaries known as in the vascular system
the business end that link arteries and veins
whats the role of a pericyte
provide homeostasis for capillary vessels
what are the main 2 types of arteries in the heart
subclavian artery for limbs
carotid artery for head
whats the role of the Brachiocephalic artery
supply blood to upper right side of body
whats the role of the Internal jugular vein
drains blood from the brain, face, neck to the heart.
what is the main vein for blood draws in the upper limb
median cubital vein
what is AAA
abdominal aortic aneurysm
how does AAA occur
loss of elastin weakens the artery walls
whats the law of laplace
T = Pr/2
whats the equation for a spherical aneurysm
H = Pd/4w
where does nutrient rich blood go first
liver
what’s the job of the hepatic portal vein
carry blood to the liver
whats the job of the Inferior Vena Cava
IVC carries deoxygenated blood from lower body back to heart
which vertebrae levels does the aorta lie
T12-L4
what’s the job of the genicular arteries
supply blood to the knee
what’s the job of the iliac arteries
supply blood to lower body
what’s atherosclerosis
narrowing of arteries due to high blood pressure/cholesterol levels
which vein does blood travel through to get up the leg
popliteal vein to femoral Vein
which duct enters the right subclavian vein
right lymphatic duct
which duct enters the left subclavian vein
thoracic
where to lymph nodes leave from
medullary sinus in the deep cortex
what’s the role of lymph nodes
trap bacteria
what’s Lymphoedema
leakage of lymph into surrounding tissues
what is lymphoma
cancer related to lymphoid tissue
what is ascites
accumilation of fluid in peritoneal cavity
what are the 3 lymphatic organs
spleen
thymus
tonsils
what’s the role of the spleen
recycling of old RBC
hold reserve of blood
how is the spleen supplied and drained
splenic artery from coeliac trunk
through the hepatic portal vein
what’s the role of the thymus
production of T cells
what happens to the thymus as you get older
gets smaller and replaced by fat
what do tonsils do
gather and remove pathogens trying to enter pharynx
