Most tissue fluid returns to the blood at the venous end of the capillary because

the water potential of the blood is lower than that of the tissue fluid and hydrostatic pressure has fallen
hydrostatic pressure is higher there
it is pumped
lymph pushes it
7.

has a primary sequence
contains more than one polypeptide chain
has hydrogen bonds
is soluble
8.
Which statement best describes Atherosclerosis?
Conducting fibres that spread the impulse through the ventricle walls from the apex.
Build-up of fatty plaque (atheroma) in artery walls.
Tissue that delays the impulse then passes it to the bundle of His.
Volume of blood pumped by a ventricle per beat.
