cuticle – in hair, the outermost layer of keratinocytes originating with the hair matrix, as noticed in a very cross-section with the hair bulb.
To be aware of the complete structures and working technique of this system it is necessary to learn about the anatomy and physiology.
hypertension – power exerted by the blood in opposition to the wall of the vessel or heart chamber; might be described Along with the extra generic term hydrostatic force.
diastolic pressure – lessen variety recorded when measuring arterial blood pressure level; signifies the nominal benefit comparable to the pressure That is still during ventricular rest.
