What is hemostasis? correct answer: Hemostasis is a multistep process that maintains the integrity of a closed high pressure circulatory system after vessel injury. What is the process of hemostasis regulated by? correct answer: The normal process of hemostasis is regulated by a complex array of activators and inhibitors that maintain blood fluidity and prevent blood from leaving the vascular compartment. When is hemostasis considered normal? correct answer: Hemostasis is normal when a ...
