Composition SALTS
Supplies these to tissues and receives CARBON DIOXIDE
and other waste products from tissues.…read more

Here's a taster:

1. Pressure start of capillary bed = greater than outside the capillary
2. Difference in pressure forces fluid out
3. Fluid surrounds cells forming tissue fluid
4. After fluid left capillary, pressure is reduced in capillary bed nearer
to veins
Hydrostatic pressure created as lumen size decreases,
forces TF out of the plasma…read more

Slide 4

Preview of page 4

Here's a taster:

1. Lower hydrostatic pressure in capillary at venuous end
due to loss of tissue fluid
2. Tissue fluid outside of capillary has greater hydrostatic
pressure than inside capillary
Return of 3. Due to differences in pressure, tissue fluid forced back
into capillary by outside hydrostatic pressure forces
tissue fluid
4. Osmotic forces pull water back VIA OSMOSIS into
capillary due to proteins in the blood plasma lowered it's
water potential.…read more

Here's a taster:

Excess of TF drained into lymph vessels
Lymph vessels found in ALL CAPPILARY BEDS
Lymph vessels have very thin walls so TF can easily diffuse
into it.
Forms lymph
Not all Lymph vessels take the lymph back towards the heart to be
tissue fluid drain back into the blood near the superior vena cava.
Lymphatic system also absorbs fats from small intestines
returns... It is part of the immune system; lymph nodes = where
white blood cells develop ­ swollen when there's infection;
more WBC produced
No pump in lymphatic system, lymph moved by hydrostatic
pressure of tissue fluid that has left capillaries and muscle
contractions which squeeze lymph vessels.…read more
