A patient with hypertensic crisis has increased content of angiotensin II in blood. Angiotensin pressor effect is based on:

Answer options

1. Prostaglandin hyperproduction
2. Vasopressin production stimulation
3. Activation of kinin-kallikrein system
4. Contraction of arteriole muscles
5. Activation of biogenic amine synthesis
