What is an anastomoses?

• A type of surgical procedure to remove blood vessels.
• A condition where blood vessels are blocked.
• An anastomosis is a connection between two blood vessels or other tubular structures.
• A term for a single blood vessel.

What is incorrect concerning capillary exchange?

• To allow nutrients leave the vessels to the cell, take waste from the cell into the vessel.

• Diffusion is where substances are actively transported across the cell membrane.

• Transcytosis is where molecules are transported across a cell, from one side to the other.

• Bulk flow involves filtration and reabsorption or the movement of substances out of the capillary and into the capillary.

Does pressure flow go from high to low or low to high?

• high to low

• low to high

What is incorrect concerning filtration?

• Blood hydrostatic pressure is where the pressure is located in the blood and pushes against the vessel wall

• IF osmotic pressure is where the pressure is located in the interstitial fluid and pulls substances from the vessel

• Filtration is where nutrients/wastes are taken out of blood

• All of these are correct

What is incorrect concerning reabsorption?

• IF hydrostatic pressure is where the pressure is located in the interstitial fluid and pulls substances into the vessel.

• Blood colloid osmotic pressure is where the pressure is located in the blood and pushes substances into the vessel

• Reabsorption is where nutrients/wastes are pushed into the blood vessel

• All of these are correct
