involved in clotting
(plasma proteins) what are globulins involved in?
transport and the immune system
(blood) blood transports oxygen and carbon dioxide to where?
(blood) transports digested food from where?
the small intestine to cells
(blood) transports nitrogenous waste from where?
cells to excretory organs
(blood) transports platelets to where?
(blood) transports cells and antibodies involved in what?
(blood) transports what chemical messengers?
(tissue fluid) surrounds cells and is made from what?
substances leaving blood plasma
(tissue fluid) how do substances move out of capillaries into tissue fluid?
(tissue fluid) as blood flows through arterioles to capillaries what type of pressure is it under?
hydrostatic from the hearts contractions
(tissue fluid) at the arterial end of the capillary hydrostatic pressure is what?
high - 4.6
(tissue fluid) the high hydrostatic pressure at the arterial end does what?
forces blood out of the capillary
(tissue fluid) the oncotic pressure is what at the arterial end?
lower than the hydrostatic
(tissue fluid) at the venous end what is the hydrostatic pressure?
low - 2.3
(tissue fluid) what is the oncotic pressure at the venous end?
3.3 - higher than hydrostatic
(tissue fluid) at the venous end oncotic pressure is higher than hydrostatic so the fluid does what?
moves back into capillaries
(tissue fluid) what percentage of tissue fluid returns to the blood?
(lymph) 10% of the fluid that doesn't go back to the blood goes where?
into lymph capillaries
(lymph) lymph has less what?
oxygen and nutrients
(lymph) lymph has fatty acids from where?
the villi of the small intestine
(lymph) lymph capillaries join to form what?
(lymph) the lymph is moved by what?
breathing and muscle contraction
(lymph) what builds up in the lymph nodes?
(lymph) lymph nodes intercept what?
the bacteria digested by the phagocytes in the nodes
