Arterial blood pressure Arterial BP is defined as lateral pressure exerted by the column of blood on wall of arteries Usually hypertension is defined as blood pressure above 140/90, and is considered severe if the pressure is above 180/120. High blood pressure often has no symptoms. Over time, if untreated, it can cause health conditions, such as heart disease and stroke. Eating a healthier diet with less salt, exercising regularly and taking medication can help lower blood pressure.

12. Determination of Arterial
Blood Pressure

13. Some factors are necessary to maintain normal blood pressure. These
factors are called local factors, mechanical factors or Determinants of
blood pressure
Local factors are of two types
I) , which are pretaining to heart:
1. Cardiac output
2. Heart rate
II) , which are pretaining to blood and blood vessels:
3. Peripheral resistance 7. Velocity of blood flow
4. Blood volume 8. Diameter of blood vessels
5. Venous return 9. Viscosity of blood
6. Elasticity of blood vessels

14. Regulation of Arterial
Blood Pressure

17. ► Nervous regulation is rapid among all the
mechanisms involved in the regulation of
arterial blood pressure.
► Although nervous mechanism is quick in
action, it operates only for a short period and
then it adapts to the new pressure.
► Hence, it is called short-term regulation.
► The nervous mechanism regulating the
arterial blood pressure operates through the
vasomotor system.

19. Vasoconstrictor fibers belong to
the sympathetic division of autonomic
nervous system.
These fibers release
neurotransmitter substance like
noradrenaline
Noradrenaline acts through alpha
receptors of smooth muscle fibers in
blood vessels.

20. Parasympathetic vasodilator fibers cause dilatation of blood
vessels by releasing acetylcholine.
Sympathetic fibers cause vasodilatation in certain areas, by
secreting acetylcholine.
Such fibers are called sympathetic vasodilator or sympathetic
cholinergic fibers.
.
Some impulses pass through the other branches of the axon in
the opposite direction and reach the blood vessels supplied by
these branches.
These impulses now dilate the blood vessels.
