Exercise 6 Review sheet tissue
Orthopedic surgeons are fond of saying, "It is better to break a bone than it is to tear a tendon or ligament." Why is this true?
Broken bones heal faster and with less scar tissue because they are more vascularized than tendons or ligaments.

Explain why a buccal swab procedure should not cause bleeding.
Epithelium is avascular. Removing a few cells from the apical layer of the epithelium will not damage any blood vessels.
Smoking impairs cilia because the toxins paralyze and can destroy the cilia. Based on this loss of function, explain which types of infections smokers would be more susceptible to.

When cardiac muscle tissue dies in adults, it is replaced with scar tissue composed of dense connective tissue. Explain how scar tissue would affect the function of the cardiac muscle tissue.
The scar tissue cannot contract so the heart will be weaker.
