Cards

Term
Anastomosis
Definition

the site where two or more arteries (or two or more veins) converge to supply the same body region

 

EX:  superior and inferior epigastric arteries

Term
End arteries
Definition

provide only one pathway through which blood can reach an organ

 

EX:  renal artery of the kidney and the splenic artery of the spleen

Term
Both artery and vein walls have three layers called
Definition
tunics
Term
Tunica intima
Definition

the innermost layer of a blood vesel wall

composed of endothelium CT

Term
tunica media
Definition

is the middle layer of the vessel wall

 

smooth muscle cells

Sympathetic innervation

vasoconstriciton

vasodilation

Term
Tunica externa
Definition

outermost layer of the blood vessel wall

 

areolar CT

helps achor the vessel to other structures

Term
Arteries transport blood
Definition

away from the heart

 

Term
Elastic Arteries
Definition

are the largest arteries

 

also called conducting arteries because they conduct blood away from the heart to the smaller muscular arteries

 

EX:  aorta, pulmonary, brachiocephalic, common carotid, subclavian, and common iliac arteries

Term
Muscular Arteries
Definition

Also called distributing arteries

distribute blood to body organs and tissues.

 

EX:  brachial, anterior tibial, coronary, and inferior mesenteric arteries

Term
Arterioles
Definition

smallest arteries

 

 

Term
Capillaries
Definition

smallest blood vessels, connect arterioles to venules

 

Also called functional units of the cardiovascular system

Term
What are the three types of capillaries
Definition

continuous capillaries

fenestrated capillaries

sinusoids

Term
Veins
Definition
drain capillaries and return the blood to the heart
Term
Venules
Definition

are the smallest veins

companion vessels with arterioles

Term
Valves
Definition

prevent blood from pooling in the limbs and assist blood moving back to the heart

 

they close to prevent backflow

Term
Deep vein thrombosis
Definition

a blood clot in a vein

 

EX:  calf (sural) most common site, femoral region

Term
Oxygenated blood is pumped out ot the left ventricle of the heart and enters the
Definition
ascending aorta
Term
The ascending aorta gives off the
Definition
left and right coronary arteries to supply the heart
Term
What are the aortic arch branches
Definition

three branches

 

1)  the brachiocephalic trunk

2)  the left common carotid artery

3)  the left subclavian artery

Term
Descending thoracic aorta
Definition
extends several branches to supply the thoracic wall
Term
Descending abdominal aorta
Definition

bifurcates into common iliac arteries

these vessels divide into internal and external iliac arteries

Term
Deoxygenated blood returns to the heart via
Definition
the superior and inferior venae cavae
Term
Which arteries supply most of the blood to the head and neck
Definition
Common carotid arteries branch into the internal and external carotid arteries
Term
The arterial anastomosis that supplies the brain
Definition
the cerebral arterial circle
Term
What drain the cranium
Definition
vertebral veins and the dural venous sinuses
Term
Which veins drain the left side of the thorax
Definition
Hemiazygos and accessory hemiazygos
Term
Which veins drain the the right side of the thorax
Definition
azygos vein
Term
Which arteries supply the diaphragm
Definition

Superior phrenic artery

Musculophrenic artery

Inferior phrenic artery

Term
What three unpaired arteries supply the gastrointestinal tract organs
Definition

Celiac trunk

Superior mesenteric artery

Inferior mesenteric artery

Term
Subclavian artery
Definition
continues as the axillary artery and then becomes the brachial artery
Term
The brachial artery divides into what two arteries
Definition

ulnar artery

radial artery

Term
The external iliac artery extends inferior to the inguinal ligament and is renamed what
Definition
the femoral artery
Term
The femoral artery enters the popliteal fossa and then becomes what
Definition
the popliteal artery
Term
The popliteal artery divides into
Definition
anterior and posterior tibial arteries
Term
The posteior tibial artery gives off a ___________ artery
Definition
fibular
Term
The posterior tibial artery branches into what
Definition
medial and lateral plantar arteries
Term
Oxygenated blood is pumped from which part of the heart
Definition
the left ventricle through the systemic circulation and back to the right side of the heart
Term
Deoxygenated blood is pumped from what part of the heart
Definition
the right ventricle through the pulmonary circulation and returns as oxygenated blood to the left side of the heart
Term

Three bilateral venous systems connect the sinus venosus of the heart

What are they

Definition

Vitelline system

Umbilical system

Cardinal sysem

Term
Hepatic Portal Circulation
Definition
Venous drainage of most abdominal organs is an example of a portal system in that there are two carpillary beds in a series connected by a portal vein.  In the way the blood drained from the abdominal organs can be processed in the liver's wide sinusoid capillaries before going back into systemic venous circulation
