Q

Where does the infection for endocarditis come from

A

bacteria, fungi, or other microorganisms from another part of the body such as the mouth, limb abscess, or lung infection that spreads through the bloodstream and attaches to damaged areas in the heart (it loves attaching to valves)

101
Q

What happens if the flow rate of the vessels decreases?

A

decreased flow = decreased O2 to tissue = causes ischemia and malnutrition

102
Q

How do the arteries change with metabolic needs?

A

Increased need = arterial dilation

Decreased need = arterial constriction

103
Q

What happens when vessel function is impaired?

A

Cells are malnourished

Arterial - no O2 or nutrients

Venous - system clogged with wastes and excess fluid

A

return deoxygenated blood to the heart

have thinner less muscular walls

flow is controlled by valves - when the valves are incompetent they cannot push or pull blood back up to the central circulation

106
Q
