What is a fenestrated capillary? ✔Correct Answer-More permeable than continuous capillaries
Function in absorption or filtrate formation (small intestines, endocrine glands and kidneys)
Are not found in the brain
Why is the left ventricular heart wall thicker than the right? ✔Correct Answer-It helps it pump
blood with greater pressure to whole body right only pumps to lungs.
What happens with a thromboembolic disorder? ✔Correct Answer-Involves embolus formation, a
clot moving throughout the circulatory system
Which blood type is a universal donor? ✔Correct Answer-Type O
What are functions of myocardial cells? ✔Correct Answer-as a whole heart contracts as a unit or it
does not contract at all
What events occur when the semilunar (SL) valves are open? ✔Correct Answer-Blood enters
pulmonary arteries and aorta
AV valves are closed
Ventricles are in systole
What epithelia supports the tunica intima? ✔Correct Answer-Squamous epithelium supported by a
sparse connective tissue layer
What are three main factors influencing blood pressure? ✔Correct Answer-Cardiac output (CO)
Peripheral resistance
Blood volume
What are the parts of the heart's conducting system? ✔Correct Answer-AV node
SA node
Bundle of His
What regulates cerebral blood flow? ✔Correct Answer-Intrinsic autoregulatory mechanisims
What is the source of blood going to capillaries in the myocardium? ✔Correct Answer-Coronary
arteries
Platelets .... ✔Correct Answer-stick to area of damaged blood vessel and help to seal the break
What is caused by hemorrhaging and a large loss of blood? ✔Correct Answer-A lowering of blood
pressure due to a change in cardiac output
What is the plasma protein that is a main contributor of osmotic pressure? ✔Correct Answer-
Albumin
Blood flow through the vascular system is equal to? ✔Correct Answer-Cardiac output
, What is an isovolumetric contraction? ✔Correct Answer-The short period during ventricular systole
when the ventricles are completely closed
What is the primary function of capillaries? ✔Correct Answer-Permitting the exchange of nutrients
and gases between the blood and tissue cells
What are some protective functions of blood? ✔Correct Answer-prevention of blood loss and
infection
What are sinusoids?, ✔Correct Answer-Modified capillaries with large clefts
Peripheral resistance increases as what else increases? ✔Correct Answer-Blood viscosity increases
Where in the body is blood flow velocity the slowest? ✔Correct Answer-In the capillaries
Blood is what type of substance? ✔Correct Answer-Fluid tissue,suspension
What are some functional characteristics of WBC? ✔Correct Answer-Diapedesis, amoeboid motion
and positives chemotaxis
What is the slowest step in the clotting process? ✔Correct Answer-Formation of prothrombin
activator
Blood in pulmonary veins returns to where? ✔Correct Answer-Left atrium
Some basic facts about heart valves ✔Correct Answer-AV valves are supported by chordae
tendineae, tricupus valve divide the bicupus so that regurgitation of blood into the atria during
ventricular contraction does not occur.
What vessels receive blood during ventricular systole? ✔Correct Answer-Aorta and pulmonary
trunk
The tunic of an artery most responsible for maintaining blood pressure? ✔Correct Answer-Tunica
medica
What organ regulates red blood cell production? ✔Correct Answer-kidney
What layer of the heart contracts? ✔Correct Answer-Myocardium
Where do arteries carry blood in regard to the heart? ✔Correct Answer-All carry blood away from
the heart
What is the most common type of blood capillary? ✔Correct Answer-Continuous capillary
When does blood flow increase to skin? ✔Correct Answer-When environmental temperature
increases o rise
What is hypovolemic shock? ✔Correct Answer-Shock that results from large-scale loss of blood
volume, or after severe vomiting or diarrhea
