5.(a) The force is

provided by the pumping action of the heart..

(b) Capillaries are extremely fine. Their walls consist of only one layer of cells and are thus very permeable.

(c) Blood capillaries

form a dense network for linking an artery, and a vein, while lymph capillaries are composed of blind ducts and normally larger than blood capillaries.

(1) (1) White blood cells

can kill invading agents by

engulfing them or by secreting antibodies,

and promote blood clotting and tissue repair...

(2) Salts contribute

to usmotic pressure,"to" form

buffer systems. (3) Clotting of blood

prevents further bleeding and contamination by foreign agents.

(g) Because lymph

contains higher amount

chlon of protein and

the osmotic pressure of lymph is higher, the water would flow from

tissue fluid to lymph through the wall of lymph capillaries by usmosis.
