Study Notes
Anatomy and Physiology
- Anatomy is the study of the structure of body parts and their relationships to one another, and can be classified into three types: gross or macroscopic, microscopic, and developmental.
- Physiology is the study of the function of the body's structural machinery.
Types of Anatomy
- Gross Anatomy can be further divided into two categories: regional and systemic.
- Regional anatomy involves the study of all structures in one part of the body, such as the abdomen or leg.
- Systemic anatomy involves the study of the gross anatomy of the body by system.
Microscopic Anatomy
- Cytology is the study of the cell.
- Histology is the study of tissues.
Levels of Structural Organization
- There are six levels of structural organization: chemical, cellular, tissue, organ, organ system, and organismal.
- Atoms combine to form molecules at the chemical level.
- Cells are made up of molecules at the cellular level.
- Tissues consist of similar types of cells at the tissue level.
- Organs are made up of different types of tissues at the organ level.
- Organ systems consist of different organs that work together closely at the organ system level.
- The human organism is made up of many organ systems at the organismal level.
Examples of Tissues and Organs
- Examples of tissues include epithelial tissue, smooth muscle tissue, and connective tissue.
- Examples of organs include the heart, which is part of the cardiovascular system.
- A blood vessel is an example of an organ that is made up of different types of tissues.
