Specialised cells that make up the juxtaglomerular apparatus of the kidney can sense changes in BP.

blood vessels and circulation

Normally, the MAP falls within the range of 70— mm Hg. Mean is a statistical concept and is calculated by taking the sum of the values divided by the number of values.

blood flow rate

Although there are five recognized Korotkoff sounds, only two are normally recorded. Oxygen and carbon dioxide move across the capillary wall by diffusion.

resistance to blood flow
