Cardiovascular Part 1

_____~60,000 miles worth of ___ through body and 5-6 liters of ___

_____ pumps blood out to lungs and back to heart (Right side of heart) ventricle

_____pick O2 from alveoli, deliver nutrients, pick up all CO2 back to heart then back out to lungs

_____ send blood out to capillary in lung and don't push blood very far, 30-40mmHg

In blood distribution___ is 7%

In blood distribution___ is 9%

In blood distribution___ is 11%

In blood distribution___ is 12%

In blood distribution___ is Systemic Veins and Venules

_____ has the largest blood volume by far in circulation

Artery->____->Capillary->____->Veins-> ____

____is where exchange takes place, btwn tissues and circulatory system, one cell thick

____eventually give way to the very smallest vessels in body called capillaries

120mmHg is pushing out into _____ system

____ carries blood away from heart and come out an artery

____ branch into smaller vessels called arterioles

____branches off to send blood to all the different organs, including: liver, kidney andbrain

Going into venules we eventually give way to larger vessels called____.

____ side is low pressure side

In a structure of ____ there's more smooth muscle around it to control BP

Major__ and veins are structured similarly

____ have Tunica Intima (internal layer), thickest to hold pressure

____consists of Tunica Intima, Tunica Media and Tunica Adventitia

____has endothelium(endothelial cells) in artery

____ has smooth internal layer that blood rubs up against as blood flows through system

___(endothelial cells) are surrounded by Tunica Media

___ is the middle and thickest layer of artery

____is where there's smooth muscle and is the structure of uterus and digestive tract in artery

____is the outside layer,which is a heavy connective tissue that surround Tunica Media in artery

____ tissue in artery hold everything together and keeps blood vessels intact

In the structure of_____pressure starts to drop a little and there's a little less smooth muscle

In the structure of_____there

In the structure of_____there's thin endothelial cells only, which is the only way to move into and out tissues

In the structure of_____, which is the next size up from the capillaries, has Tunica Intima surrounded by a little Tunica Adventia

____ have no Tunica Media and pressure is small

____ are superior and inferior vena cava on systemic side

In the structure of_____ there Tunica Intima,which extend into vessel to create small valves and has Tunica media,which is thinner

_____tunica externa act differently due to pressure compared to arteries

In mechanisms of control of blood flow ____ have vasoconstriction, stimulation and inhibition

In the major artery,____ is the primary control of blood flow

In the major artery,____ is created by autonomic NS by clamping down on blood vessel and BP >and force >

In the artery,____ cause smooth muscle to contract reducing diameter of vessel, which results in increased BP

What are the 3 ways to control blood flow through a capillary bed?

In ____able to by pass certain capillary beds, directly to venule by using metarterioles

___ is used to control oxygen and nutrient concentration in capillary

____are high metabolic activity, which increases # of capillaries causing ___capillary ratio

In____high metoblic areas in body are gut, brain (b/c O2) and muscles

____shuns blood away from certain capillaries or towards

____is 600 square meters

What are the 3 mechanisms of movement across semipermeable capillary membrane?

What are 2 parts of diffusion?

____easily move across cell membrane b/c cell membrane has a lipid bilayer, which easily move into cell

In diffusion____ generally remain in the blood b/c they are not lipid soluble and are to large to fit through pores or btwn cells

In ____generally movement is from the tissues into the capillaries creating an inward force of ______Pressure

In____ there's a movement of substances due to direct blood pressure called_____.

What are the two ends in Filtration?

At the _____end there is a outward hydrostatic pressure of 36.3mmHg

At the ____end there is a inward Osmotic Pressure of 28mmHg

Net movement of ____ end is 8.3mmHg, which is going of Capillaries

What are two effects that alter capillary permeability?

Chemical Effects are composed of ____ and ____

What is the Structural Effects?

____ is a chemical effect b/c it's produced by basophils

Increasing____make capillaries more leaky

____is a lekocyte that goes up during infection

In____ there is a tight junction btwn endothelial cells in capillaries to brain than other tissues

lipid soluble substances move easier across_____.

_____changes take place from drug concentration to neurons to brain b/c drugs have a hard time moving across the membrane

In ____ the 3 mechanisms of blood flow are Valves, Skeletal Muscle Contraction and Breathing

___ are low pressure side and move things in one direction

_____contract muscles in veins and squeeze vessel and blood moves in both directions

____and diaphargm helps bring blood back to heart

As we get closer to heart pressure in____ is close to 0mmHg

____typically outside of leg, venous malfunction, and abnormal dilations

Circulation Routes involve mainly what two circulations?

During circulatory routes there's generally only__ capillary bed per circuit

In___left ventricle->body->Right atrium, which is oxgenated blood coming out and leaving

In___blood flow to heart drive hydrostatic pressure

What are the three special circulations in systemic circuit?

In_____Circulation, 1st vessels off aorta go directly to heart to ___ artery

____ is block in coronary arteries to heart muscle tissue causing low O2 concentration and tissue doesn't work properly

____ is chest pain and nitroglycerin helps this problem

___effects smooth muscle around blood vessels causing them to relax

____ dead tissue on surface of heart, cause heart attack, also a type of coronal circulation, 20mmHg needs to go back to heart

____ from digestive tract is the 1st capillary bed sent through vein and protect from wastes so their not sent to rest of body

____ involve the Circle of Willis

___ is at base of brain, has a set of arterioles and arteries that connect circle around the base of brain

____ is what 30-40% of population have

In____ if linear flow is blocked sending bloodto sending blood to other parts of brain one direction then we can go another direction
