Study Notes
Key Concepts in Homeostasis and Anatomy
- Homeostasis refers to the maintenance of a constant internal environment within an organism.
- Anatomy focuses on the structure of organisms, while physiology is concerned with their function.
- The relationship between anatomy and physiology highlights that structure often dictates function.
Interdependence of Biological Systems
- A chemical imbalance in the blood can lead to heart failure, affecting the functioning of other tissues.
- This illustrates the interdependency of all organizational levels within an organism.
Levels of Biological Organization
- Levels of organization from complex to simplest are: organism, system, organ, tissue, cell, and molecule.
- The cellular level represents the smallest unit of living organization.
Study of Tissues
- Histology is the branch of biology that studies tissues and their structures.
- Epithelial tissue serves to cover and protect the body's exposed surfaces.
- Connective tissue fulfills roles such as filling internal spaces and providing structural support.
Functions of Biological Systems
- The skeletal system plays key roles in protecting soft tissues, mineral storage, and facilitating blood formation.
- The endocrine system is primarily responsible for the long-term regulation of activities across various organ systems.
