Carry
oxygenated
blood
away
from the heart
View source

View source
What is the lumen size of capillaries?
5 to 10
microns
View source
What are pericytes?
Contractile cells
that regulate blood flow
View source
What is the function of fenestrations in capillaries?
Allow rapid exchange of
substances
View source
What is the musculo-venous pump?
Also known as the
skeletal muscle pump
Assists in
venous return
Works against gravity
View source
What does the pulmonary trunk carry?
Deoxygenated blood from the
right ventricle
View source
What is the role of systemic circulation?
Delivers
oxygen
and picks up
carbon dioxide
View source
Describe the blood flow through the heart.
Arteries
carry blood away from the heart
Veins
carry blood towards the heart
Blood flows through
chambers
and
valves
View source
What is the function of the tricuspid valve?
Separates
right atrium
and
right ventricle
View source

Subclavian artery
Axillary artery
Brachial artery
Radial artery
Ulnar artery
View source
What are the deep and superficial veins of the upper limb?
Deep
veins: Same name as arteries
Superficial veins:
Basilic
and
Cephalic
View source
What is the function of the femoral artery?
Supplies blood to the
thigh
and leg
View source
What happens to the femoral artery at the adductor hiatus?
It becomes the
popliteal artery
View source

Supplies blood to the
posterior compartment
of the leg

Supplies blood to the
foot
and toes
View source
How do deep veins differ from superficial veins?
Deep veins are within
muscular compartments
View source
What is the function of the great saphenous vein?
Drains blood from the
lower limb
View source
What is the significance of collateral vessels?
Allow
continuous
blood supply during movement
View source
What is the role of the median cubital vein?
Connects
basilic
and
cephalic
veins
View source

Supplies blood to the
knee
and lower leg
View source
What arteries branch from the popliteal artery?
Anterior and posterior tibial arteries
