IMED3001 Lymphatics Notes
Recap on capillaries
● Capillaries filter more than reabsorb
○ (~90%)
■ Excess fluid
● (10%)
○ enters lymphatic vessels
Lymphatic drainage
● Thoracic duct drains into subclavian vein
Question
● So what happens when we add in gravity?
○ Standing for 15 minutes
■ reduces blood plasma volume
■ by >10%
OEDEMA
● The accumulation of
○ excess fluid
○ in the interstitial space
● Causes
○ Increased capillary hydrostatic pressure
■ (usually ⇑ venous pressure)
○ Decreased Plasma Oncotic Pressure
■ (PCOP)
■ ( ⇓ plasma albumin)
