Circulation in blood vessels Flashcards
Main type of blood vessels
Artery
Capillary
Vein
Connective tissues found in vessel walls: collagen
Its strengthen the blood vessel to withstand the pressure changes
Connective tissues found in vessel walls: smooth muscles
Controls the constriction & dilatation of blood vessels
Connective tissues found in vessel walls: elastic fibers
It allows the blood vessel to stretch to accommodate the greater volume of blood
Artery
Arteries carry blood away from the heart toward the cells in the body
Almost all arteries carry oxygenated blood except for pulmonary and umbilical artery
Artery - structure related to function: smooth endothelium lining
Arteries contain smooth endothelium lining to reduce friction between wall & blood
Artery - structure related to function: collagen
The wall of the arteries contain collagen layer to withstand high blood pressure
Artery - structure related to function: elastic fibres
The wall of the arteries contain elastic fibres allowing the arteries to stretch & recoil maintaining high bald pressure
Artery - structure related to function: smooth muscles
The smooth muscles in the artery wall enables the arteries to change diameter
Capillary
Capillaries connect arteries to veins
The primary function of capillaries is the exchange of materials between the blood and tissue cells
Capillary - structure related to function:
Vein
Veins carry blood towards heart
Most veins carry deoxygenated except pulmonary & umbilical vein
Vein - structure related to function:
