BIOL 2222 Blood Flow Regulation & Select Vessels

True of False? Capillary Hydrostatic Pressure is the same as Blood Pressure inside the Capillaries.

• True

• False

When regulating the amount of blood flow to skeletal muscles, is the release of Angiotensin II to cause Vasoconstriction an Intrinsic or Extrinsic mechanism?

• Intrinsic

• Extrinsic

Hydrostatic Pressure in your Interstitial Fluid is usually about what number?

• 0 mmHg

• 17 mmHg

• 35 mmHg

• -8 mmHg

Lymphatic Capillaries drain fluid from where?

• Intracellular fluid

• Capillary Beds

• Extracellular Fluid

• Interstitial Tissue

Which of the following best defines Osmotic Pressure in the Capillaries (OPc)?

• None of the following

• The pressure of blood flow being pushed back into the vessel after leaving the tissue.

• The “suck” created by water being pulled back into capillaries

• Pressure gradient created from protein content in tissues

What is the function of your Hepatic Portal Circulation?

• To carry oxygen rich blood to the liver for CO2 exchange

• To carry oxygen and nutrient rich blood to the liver for filtration and storage

• To drain the intestines of deoxygenated but nutrient rich blood and filter it through the Liver

• To drain the intestines of oxygen rich blood and carry it to the lungs for CO2 exchange.

Is the Net Force at the arteriole end lower or higher than at the venous end and why?

• Higher; Because there is more hydrostatic pressure being exerted at the arteriole end of a capillary

• Lower; Because there is more hydrostatic pressure being exerted at the arteriole end of a capillary

• Higher; Because there is less hydrostatic pressure being exerted at the arteriole end of a capillary

• Lower; Because there is less hydrostatic pressure being exerted at the arteriole end of a capillary

True or False? Net Filtration Pressure is measured by subtracting Outward Pressures from Inward Pressures.

• True

• False

The Brachiocephalic, L. Common Carotid, and L. Subclavian Arteries feed what?

• Chest & Arms

• Arms & Legs

• Chest & Abdomen

• Arms & Head

Which cluster of arteries feeds the Liver, Spleen, and Gastric Structures?

• Gonadal Arteries

• Superior Mesenteric Trunk

• Celiac Trunk

• Inferior Mesenteric Trunk
