A&P II - Blood Vessels and Hemodynamics

Inner most layer of blood vessels

• Endothelium

• Smooth muscle

• Elastic lamina

• Basement membrane

Section of the layers of blood vessels that contains smooth muscle and external elastic lamina in arteries

• Tunica interna

• Tunica externa

• Tunica media

• Tunica elastica

Union of branches of 2 or more arteries supplying same body region

• Collateral circulation

• End artery

• Anastamosis

• Collaborate circulation

Alternative route of blood flow to a body part

• Diversion circulation

• Anastamosis circulation

• Collateral circulation

• Compensation circulation

Arteries that do not Anastamose

• End arteries

• pollicis arteries

• Distal arteries

• Terminal arteries

continuation of the metarteriole that enables blood to bypass a capillary bed and flow directly into a venule, creating a vascular shunt

• bypass channel

• Thoroughfare channel

• Capillary channel

• Capillary sphincter channel

Blood vessel composed of a single layer of endothelial cells on basement membrane

• Distributive vessels

• Conducting vessels

• Exchange vessels

• Resistance vessels

Answer explanation

Exchange vessels are also known as capillaries

Vein with thin endothelial wall with no smooth muscle

• Capillary

• Vascular sinus

• Arteriole

• Elastic artery

Most blood in the body is in the

• Pulmonary vessels

• Heart

• Systemic arteries and arterioles

• Systemic veins and venules

If net filtration pressure is positive fluid inside the capillary will

• Leave the capillary

• Remain in the capillary with no exchange of outside fluids

• Remain in the capillary as outside fluid rushes into the vessel

• Have equal exchange of fluid coming into and leaving the vessel
