Anatomy & Physiology Study of human biology is divided into two primary areas.

1. Anatomy - (Greek Ana = up, tome cutting) field of study that describe the A. Gross Anatomy - study of body structures that are B. Microanatomy Histology - level only. . C. Systematic Anatomy - Studies body structure (skeletal, muscular). D. Regional Anatomy region (head, leg). with in a given

n 2. Physiology - (Greek physio = nature, logic=study) n n A. Human physiology – Study of specific B. Cellular & Systemic Physiology – emphasizes

Structural Levels of Organization n Small (Simple) to Large (Complex)

Negative Feedback

2. Positive feedback - rare in a healthy body because a change in normal state

Health & Disease any reduction from the Acute – Chronic – Symptoms - sensations, dizziness, pain Diagnosis - identifying a disease from its symptoms

Classification of disease 1. Congenital Can be inherited May cause death Ex. 2. Immunological – Defense reaction by white blood cells (WBC’s) Ex. 3. Metabolic May cause death trauma. Ex. 4. Neoplastic Ex.
