| Factors affecting blood flow | Sympathetic nerves, hormones and local factors i.e. metabolic and endothelial
🗑

| Mean arterial pressure = | diastolic pressure + 1/3 pulse pressure
🗑

| Metabolic controls that dilate blood vessels | decrease O2, increase CO2, decrease pH, increase prostaglandins, increased osmolarity, increased nitric oxide
🗑
|

| Nerves that constrict the blood vessels | Sympathetic
🗑

| Hormones that constrict the blood vessels | alpha receptors, ADH, angiotensin II
🗑
