Study Notes

Overview of Anatomy and Physiology

Anatomy delves into the body's structure and relationships among body parts.
Physiology focuses on body functions and the mechanisms behind how body parts work.

Topics of Anatomy

Gross Anatomy: Studies large structures visible to the naked eye like the heart and lungs.
Microscopic Anatomy: Examines structures at a cellular level, including:
- Cytology: Study of individual cells.
- Histology: Study of tissues.
Developmental Anatomy: Investigates changes in body structures throughout life; includes embryology, focused on intra-uterine development.

Topics of Physiology

Subdivisions pertain to specific organ systems, such as:
- Cardiovascular Physiology: Functions of heart and blood vessels.
- Neurophysiology: Functions of the brain, spinal cord, and nerves.
- Renal Physiology: Kidney functions and urine formation.

Levels of Structural Organization

Chemical Level: Atoms comprise the simplest units of matter and combine to form molecules (e.g., water, proteins).
Cellular Level: Cells are formed from molecules and organized into tissues.
Tissue Level: Similar types of cells group to form tissues.
Organ Level: Different tissue types combine to create organs (e.g., stomach).
Organ System Level: Various organs work together to form systems (e.g., cardiovascular system).
Organismal Level: The human body as a complete entity made up of multiple organ systems.

Cellular Structure and Function

Cell shape and structure are tailored to their specific functions.

Interrelationships Among Organ Systems

Organ systems collaborate, for example:
- Integumentary System: Protects the body and interacts with the external environment.
- Digestive and Respiratory Systems: Ingest nutrients and oxygen, respectively, facilitating distribution via the bloodstream.
- Urinary and Respiratory Systems: Eliminate metabolic waste to maintain homeostasis.

Body Systems

Integumentary System: External covering, protection, vitamin D synthesis, sensory receptors.
Skeletal System: Provides support, movement framework, blood cell formation, and mineral storage.
Muscular System: Facilitates movement, posture maintenance, and heat production.
Nervous System: Fast response system regulating muscle and gland activation.
Endocrine System: Hormone-secreting glands that control growth, metabolism, and reproduction.
Cardiovascular System: Blood circulation, transporting oxygen, carbon dioxide, nutrients, and waste.
Lymphatic System/Immunity: Returns fluids, disposes of debris, and houses immune cells.
Respiratory System: Oxygen supply and carbon dioxide removal via gas exchange in the lungs.
Digestive System: Processes food into absorbable units; eliminates indigestible waste.
Urinary System: Removes nitrogenous wastes, and regulates fluid and electrolyte balance.
Male and Female Reproductive Systems: Facilitate reproduction through gamete production and nurturing offspring.

Conclusion

Understanding the interconnectedness of anatomy and physiology is crucial for studying human health and disease. Each component plays a vital role in maintaining overall body function.
