LEAVE ACCRUAL RECORDS. Vacation and sick leaves are accrued based on the leave accrual codes established on the Payroll Personnel System (PPS). Leave code is established by the department when an appointment is initially set up.

For muscles to contract there needs to be an adequate supply of ATP within the cell. ATP is generated in part by a supply of glucose and oxidative phosphorylation. An inadequate supply of blood will not provide enough oxygen to keep up with the energy demands of contraction.

Because a constant supply of blood is so essential, the arteries supplying blood to the brain have the ability to narrow and widen as needed to ensure adequate oxygen and nourishment. Likewise, blood vessels within the brain widen and narrow to regulate the flow of blood to those areas of the brain working hardest.
