UNIT 1: Organization of the Human Body Flashcards
The “science of body STRUCTURES” and the relationships among them.
- Example: Major organs like the liver and small structures such as the cells and tissues.
Anatomy
The “science of body FUNCTIONS” that is concerned with how the body works.
- Example: How the heart pumps blood and regulatory mechanisms that maintain the amount of blood ejected every minute (cardiac output).
Physiology
Structure determines ________.
The structure of the provides insight into their function.
**So for example, the bones in the skull would have to be tightly joined in order to form a case that can protect the brain.
On the other hand, the bones in a finger would be more loose to allow movement.**

Renal Physiology
- SUBSPECIALTIES OF PHYSIOLOGY -
Changes in cell and organ functions due to muscular activity.
Exercise Physiology
- SUBSPECIALTIES OF PHYSIOLOGY -

Pathophysiology
- LEVELS OF STRUCTURAL ORGANIZATION -
The most basic level of organization with substances involving in chemical reactions.
- Example: atoms (smallest unit of matter), molecules (two or more atoms joined together)
Chemical Level
- LEVELS OF STRUCTURAL ORGANIZATION -
Cells are the basic structural and functional units of an organism.
Composed of chemical and are also the “smallest living units in the human body”.
Cellular Level
- LEVELS OF STRUCTURAL ORGANIZATION -
Certain cells (group of cells) that work together and perform specific functions.
- Example: epithelial, connective, muscle, and nerve ___?
Tissue Level
- LEVELS OF STRUCTURAL ORGANIZATION -
Structures made up of two or more different tissue types and perform specific functions.
Organ Level
- LEVELS OF STRUCTURAL ORGANIZATION -
A system composed of several organs with common function.
- Example: The nose, pharynx, trachea, bronchus, and lung would all belong here.
Organ System Level
- LEVELS OF STRUCTURAL ORGANIZATION -
Organism with functioning body parts.
This is “you”.
Organismal Level
- LEVELS OF STRUCTURAL ORGANIZATION -
Enumerate the six (6) levels of structural organization.
- Chemical Level
- Cellular Level
- Tissue Level
- Organ Level
- Organ system Level
- Organismal Level
**CCTOOO
- BODY SYSTEMS -
Body system responsible for:
1. Supports and protects the body
2. Provides surface area for muscle attachments.
3. Aids in Body movement.
4. Houses cells that rpoduce blood cells.
5. Stores minerals and lipids
Skeletal System
- BODY SYSTEMS -
Body system that is responsible for:
1. Protecting the body
2. Regulating the body temperature
3. Eliminating waste in the form of “sweat”
4. Aids in making Vitamin D
5. Detects sensations (touch, pain, warmth, and cold)
Integumentary System
- BODY SYSTEMS -
Body system where skeletal muscle tissue is found.
Responsible for:
1. Body movement like walking
2. Maintains posture
3. Produces heat
Muscular System
- BODY SYSTEMS -
Body system responsible for:
1. Generating action potentials (nerve impulses) to regulate body activities.
2. Detects changes in the body’s internal and external environments.
3. Interprets changes and responds by causing muscular contractions or glandular secretions.
Nervous System
- BODY SYSTEMS -
Body system responsible for:
1. Pumps blood through the blood vessels.
2. Carries oxygen and nutrients to cells and carbon dioxide away from cells.
3. Regulates acid-base balance, temperature, and water content.
Cardiovascular System
- BODY SYSTEMS -
Body system responsible for:
1. Regulating body activities by releasing body activities by releasing hormones in the blood to a target organ.
It houses hormone-producing glands like pineal gland, hypothalamus, etc.
Endocrine System
- BODY SYSTEMS -
Body system responsible for:
1. Returns proteins and fluid to the blood
2. Carries lipid from the GTI tract to blood
3. Contains lymphocytes that protect against disease-causing microbes mature and proliferate.
Lymphatic System
- BODY SYSTEMS -
Body system responsible for:
1. Physical and chemical breakdown of food.
2. Absorption of nutrients
3. Eliminates solid wastes.
Digestive System
- BODY SYSTEMS -
Body system responsibe for:
1. Transferring oxygen from inhaled air to blood and CO2 from blood to exhaled air.
2. Regulates acid-base blance of body fluids.
3. Produces sound.
Respiratory System
- BODY SYSTEMS -
Body system responsible for:
1. Produces, stores, and eliminates urine
2. Eliminates wastes and regulates the volume and chemical composition of blood
3. Maintains acid-base balance of body fluids and body’s mineral balance
4. Also regulates the production of red blood cells.
