Blood pressure depends on the total volume of blood in the system and on the resistance provided by all the blood vessels. Peripheral vascular resistance depends on the diameter of blood vessels, the viscosity of blood and the total blood vessel length. Under normal circumstances, blood viscosity and total blood vessel length remain the same and do not affect blood pressure. Blood vessel diameter, however, can and does change from moment to moment by vasoconstriction.

In the course of prescribing, the supplementary prescriber must enter into a prescribing partnership and agree the CMP with the independent prescriber. They must also arrange for access to prescribing pads and a budget to meet the costs of prescriptions and any other costs.

Approved training programmes are at degree level and consist of at least days provided by an Institution of Higher Education and at least of learning in practice must be under supervision of a designated medical practitioner who will provide the student with support and opportunities to develop competence in prescribing practice. An outline curriculum has been developed and agreed with the HPC who also accredits programmes provided by Higher Education Institutions.

Characteristics of cancer include uncontrolled cell division with excessive growth of undifferentiated cells. Cancer cells invade surrounding tissues, whereas normal cells do not survive outside their normal boundaries.

Baroreceptors continually send impulses to the cardiovascular centre.

It is usually in solution in the blood and filters through the kidneys into the urine. In people with gout, the uric acid level in the blood exceeds its solubility and crystals are deposited in joints and other tissues. In joints this causes the synovium to become inflamed.
