The atriuretic peptides (ANP and BNP) react to increased stretch of heart muscles by:

• Decreasing blood volume and stimulating aldosterone

• Decreasing blood volume and inhibiting aldosterone

• Increasing blood volume and stimulating aldosterone

• Increasing blood volume and inhibiting aldosterone

Capillaries have a small cross sectional area

• True

• False

Lipid soluble substances

• require water-filled pores to move through endothelial cells

• pass directly through endothelial cells

• help to maintain osmotic pressure

• help to maintain hydrostatic pressure

Diffusion moves substances from

• low concentration to high concentration

• high concentration to low concentration

Fluid being reabsorbed into capillaries is mostly due to

• capillary hydrostatic pressure

• capillary osmotic pressure

• interstitial fluid hydrostatic pressure

• interstitial fluid osmotic pressure

Hypertention would increase

• CHP

• COP

• IFHP

• IFOP
