1st step in acute inflammation
- ______

vessels constrict, then dilate
why do vessels constrict in acute inflammation?
slow blood flow to area until hemostasis
why do vessels dilate in acute inflammation?
allows cells inside BV to leave
2nd step in acute inflammation
- vessels constrict, then dilate
- ________
- Neutrophils kill any foreign invaders/substances, then take off.
