What is the difference between pathology and pathophysiology?
✔✔Pathology is the study of disease causes and effects, while pathophysiology focuses on the
functional changes caused by disease.
What happens to cells during hypoxia?
✔✔Cells receive insufficient oxygen, leading to impaired function and possible death.
What is homeostasis?
✔✔The body's ability to maintain a stable internal environment.
Why is homeostasis important for health?
✔✔It keeps body systems functioning properly despite external changes.
What is an acute disease?
1
,✔✔A condition that develops quickly and lasts a short time.
What is a chronic disease?

How can genetic factors influence disease?
✔✔By predisposing individuals to certain conditions or affecting their severity.
What is a compensatory mechanism?
