Blood Vessels Flashcards
There are three types of blood vessels
: 1. Arteries. 2. Veins. 3. Capillaries.
What transport blood from the heart and distribute it to the various
tissues of the body through their branches
Arteries
Arteries always carry oxygenated except the ?
pulmonary artery which goes to the lungs
What are mostly deeply situated in the body
Arteries
It is a connection between arteries & veins
ANASTOMOSIS
Have thick muscular walls
Arteries
It serves as a backup route if one of the branches is cut off or blocked
ANASTOMOSIS
The smallest arteries are called ?
arteriole
Example for anastomosis
abdominal anastomosis between intestinal arteries
allowing the blood to flow through other branches is a function of
Anastomosis
Arteries have no valves
T/f
T
They transport blood back to the heart
Veins
Veins always carry deoxygenated except the ……… which goes to ?
pulmonary veins/ Left atrium
What unites to form larger veins?
The smaller venules (Tributries)
What commonly end in S.V.C. & I.VC.
veins
What is known to be superficial and deep in location
Veins
Have thin walls
Veins
Have wider internal lumen
Veins
Veins Have valves to ?
prevent blood flowing backwards
Describe Capillaries structure
Microscopic vessels in the form of a network
Capillaries connect what to what
the arterioles to the venules
Capillaries helps with what
They help to enable the exchange of water, oxygen and many other nutrients between blood and the tissues
