What is biocompatibility defined as?

The ability of a material to perform without any host response in a specific application
The ability of a material to perform with an adverse host response in a specific application
The ability of a material to perform with an appropriate host response in a specific application (correct)
The ability of a material to perform with any host response in a specific application

What determines the host response in biocompatibility?

Site or type of tissue in which the material is implanted (correct)
Shape of the material implanted
Color of the material implanted
Size of the material implanted

What occurs in the process called exudation?

Fluid, proteins, and blood cells escape from the injured tissue into the vascular system
Fluid, proteins, and blood cells escape from the vascular system into the bloodstream
Fluid, proteins, and blood cells escape from the injured tissue into the surrounding air
Fluid, proteins, and blood cells escape from the vascular system into the injured tissue (correct)

What are the changes that occur in the vascular system and the subsequent responses in blood-material interactions?

Following injury, changes in vascular flow, caliber, and permeability occur, leading to exudation where fluid, proteins, and blood cells escape from the vascular system into the injured tissue. These changes are followed by cellular responses. Signup and view all the answers

How is biocompatibility assessment defined and what does it measure?

Biocompatibility assessment is defined as a measure of the magnitude and duration of adverse alterations in homeostatic mechanisms that decide the host response. It measures the adverse alterations in homeostatic mechanisms. Signup and view all the answers

Explain the role of the site or type of tissue in determining the host response in biocompatibility.
