Study Notes

Structural and Functional Organization of the Human Body

The human body is structured in a hierarchical manner, starting from the simplest building blocks to complex organisms.
This organization levels:
- Chemical level: Involves the interaction and combining of atoms, such as hydrogen and carbon, to form molecules such as DNA, RNA, sugar, and water.
- Cellular level: Molecules interact further to form organelles, the functional units within a cell, such as the nucleus and mitochondria.
- Tissue level: Similar cells and surrounding tissues combine to create a tissue type, for example, smooth muscle tissue.
- Organ level: Multiple tissue types work together to form an organ, such as the bladder, which performs specific functions.
- Organ system level: A group of organs with a common function constitutes an organ system, for example, the urinary system, composed of kidneys, bladder, and ureters.
- Organism level: This encompasses all the previous levels, representing a complete living being.

Characteristics of an Organism

Organization: Defined relationships and interactions between an organism's parts, enabling them to perform specific functions.
Metabolism: The ability to use energy through chemical reactions to carry out vital functions.

Levels of Anatomy

Gross anatomy (macroscopic): Studying structures without the aid of a microscope.
- Systemic anatomy: Studying the body system by system.
- Regional anatomy: Studying the body area by area.
Surface anatomy (macroscopic): Examining the external form of the body in relation to deeper structures.
Microscopic anatomy: Studying structures using a microscope.
- Cytology: Study of cells.
- Histology: Study of tissues.
Developmental anatomy: Analyzing structural changes throughout the lifespan.
- From fertilization to death.
- Most significant developmental changes occur prenatally.

What is Physiology?

The science that explores the normal functions of living organisms and their parts.
Studies how organisms and their parts function.

Levels of Physiology

Molecular: Focuses on the functions of molecules.
Cellular: Examines the functions of cells.
Systemic: Studies the functions of specific organ systems.
- Neurophysiology: Deals with the nervous system.
- Cardiovascular physiology: Focuses on the cardiovascular system.

Studies of Anatomy or Physiology?

Measuring the electrical conductivity of the heart: Physiology.
Viewing cells under a microscope: Anatomy - Cytology.
Using a vitalograph to test lung capacity: Physiology.
Observing the deep interior structures of the brain: Anatomy - Gross anatomy - Regional anatomy.
Measuring blood pressure and heart rate after a run: Physiology.
Dissecting a heart: Anatomy - Gross anatomy - Systemic anatomy.
