10.5 Blood Pressure Flashcards
1
Q
Systole vs diastole
A
Contraction vs at rest pressure in ventricles (mmHg)
110 / 70 avg
2
Q
MAP dictates
A
Tissue perfusion
(60-90mmHg)
3
Q
Factors of BP
A
Cardiac Output and Total peripheral resistance
4
Q
Baroreceptors located in
A
Aortic and carotid bodies
5
Q
Baroreceptors stimulate control centers in
A
Medulla oblongata
6
Q
MAP formula
A
MAP= CO x TPR
CO= SV x HR
7
Q
EDV
A
End diastolic volume affects Stroke volume.
Changed based on venous pressure, blood volume, skeletal muscle and respiratory pump, ANS
8
Q
TPR effected by
A
Blood viscosity (dehydration, hematocrit)
Arteries (diameter) by ANS
Length of vessels (weight gain/loss or height)
