🗑
|
||||
| show | The 2 vertebral arteries unite on the undersurface of the brainstem
🗑

🗑
|
||||
| show | The force exerted by the blood against a vessel wall; determined by cardiac output, blood volume, and resistance
🗑
|
||||
| Peripheral resistance | show 🗑
|
||||
| show | The difference between systolic and diastolic pressure
🗑
|
||||
| show | Adjusting the diameter of blood vessels
🗑
|
||||
| show | Reduction of the diameter of a vessel that increases the resistance to blood flow
🗑
|
||||
| Vasodilation | show 🗑
|
||||
| Vasomotor center | show 🗑
