Tissue Fluid and Lymph Fluid

Question 1

What 2 parts are blood conistsed off?

Answer 1

= cells: red blood cells, white blood cells, platlets, blood clos
SUSPENDED IN BLOOD PLASMA

Question 2

What does blood plasma contain?

Answer 2

= dissolved molecules
= glucose
= amino acids
= mineral ions
= dissolved oxygen
= plasma proteins

Question 3

What else happens in the capillaries?

Answer 3

= fluid passes out of the blood and bathres tissue cells
= tissue fluid

Question 4

Where does tissue fluid leave the blood at?

Answer 4

= parts of the capillary near the artery
= transfers molecules: oxygen and glucose to tissue cells
= waste molecules from the tissue cells pass into the tissue fluid, returns back into the blood stream at the capillary near the vein

Question 5

How is tissue fluid formed/moves in and out of the blood?

Answer 5

= tissue fluid is forced out of the blood at the arterial end of the capillary
= returns back to the blood in the veniual end
=

Question 6

What happens at the arterial end of the capillary?

Answer 6

= blood at arterial end of the capillary is under relativlry high pressure still- hydrostatic pressure
= forces fluid out of the blood and into the tissue
= plasma proteins are hydrophilic (interacts with water), lower the water potential of blood plasma- tendency for water to move back into the blood by osmosis - oncotic pressure

Question 7

How is high hydrostatic pressure formed?
