Capillaries
These control flow of capillary beds, shift around blood and has knobs. When it closes, it diverts blood flow to capilkary beds, it is made up of smooth muscle.
Precapillary Sphincter
These surround and invade tissue.
Capillary Beds
Very small capillaries that go into medium veins.

Large
Anything below the heart defies _____.
gravity
Have thin walls and can expand. (coronary)

These detect blood pressure and are green.
Baoreceptors
Identify different types of chemicals and are blue. (tastebuds)
Chemoreceptors
A connection or opening between two things that are normally diverging or branching like blood vessels it can be natural or artifical and helps bypass blood.

Your portal system is in your ____.
liver
A simplest pathway is located _______.
everywhere
This circulation pathway is anastomosis and is in your fingers, toes, palms, and ears.
Arteriovenous
A circulation pathway dealing with your organs and is vein to vein.
Venous Anastomosis
A circulation pathway that is diarthrotic and is in free moving joints.
Arterial Anastomosis
Physical properties of blood flow.

Another name for nosebleed.
Epistaxis
Hypertension has ____ signs.
no

hypertension
Thinning of the wall of a vessel.
Aneurysm
What are the first four phases of the cardiac cycle?

What are the last four phases of the cardiac cycle?
ventricular systole —— blood into arteries —– semilunar valves close ——- ventricular diastole

What are the secondary causes of Hypertension?
Underlying Factors, Gestational Hypertension, Renal Failure and Heart Failure
What is involved with Gestational Hypertension?
A female being pregnant
Blood loss, dehydration, anemia, and involves genetics are all considered to be _________. (Hypotension or Hypertension)
Hypotension
Resistance of blood flow through a vessel is directly _________.
proportional
The smaller the vessel the more ____________.
peripheral resistance
When a vessel is decreased in diameter, increased in viscosity, and decrease in flow the vessel is _____.
longer
This is associated with blood vessels, it is located in the pons of the brain and controls vasodilation and vasoconstriction.
Vasomotor Center
Fight or flight and controls the diameter and radius of a blood vessel.
Sympathetic
This hormone controls diameter and radius of a blood vessel and causes vasoconstriction.
Vasopressin
Blood flow through the tissues go through ____________.
Capillary Walls
_________ is the ONLY thing in the capillary.
Endothelium
Bronchioles don’t have what?
Cartilage Rings
This means dilate and it is the process of allowing more air to flow through the bronchioles.

This means to constrict and less air is going through the bronchioles.
Bronchoconstriction
These alveolar cells have 95% surface area, are very thin and allow gas transport.
Squamous Type 1
These alveolar cells have 5% surface area, repair alveolar epithelium, and secrete a pulmonary surfactant which reduces surface tension.
