Study Notes
Anatomy and Physiology
- Anatomy studies the structure, shape, and relationships of body parts.
- Physiology examines how the body and its components function.
Levels of Organization
- Atoms are the fundamental building blocks of matter.
- Cells are the smallest units of living organisms.
- Tissues consist of similar cells working together for a common function.
- Organs are formed from two or more tissue types working together.
- Organ systems are groups of organs that collaborate to achieve a specific purpose.
- Organisms represent the highest level of structural organization.
Key Body Systems
-
Lymphatic System
- Transports fluid leaked from blood vessels back to the bloodstream.
- Lymph nodes and organs cleanse the blood and house white blood cells for immunity.
-
Respiratory System
- Supplies oxygen to the body and removes carbon dioxide.
-
Digestive System
- Breaks down food and provides nutrients to the bloodstream.
- Eliminates indigestible substances as feces.
- The liver aids in digestion by producing bile; the pancreas contributes enzymes.
-
Urinary System
- Eliminates nitrogenous wastes and regulates water, electrolyte, and acid-base balance.
-
Reproductive System
- Responsible for producing offspring.
- Testes generate sperm and male hormones; ovaries produce eggs and female hormones.
-
Skeletal System
- Composed of bones, cartilage, and joints; provides structural support and mineral storage.
-
Muscular System
- Facilitates body movement through muscle contraction.
-
Nervous System
- Fast-acting control system that responds to stimuli via the brain, spinal cord, and nerves.
-
Endocrine System
- Composed of glands that secrete hormones to regulate growth, reproduction, and metabolism.
-
Cardiovascular System
- Transports blood and is essential for oxygen and nutrient delivery throughout the body.
Maintaining Life
- Necessary life functions include:
- Maintaining boundaries between internal and external environments.
- Movement of the body and substances within.
- Responsiveness to stimuli.
- Digestion and nutrient absorption.
- Metabolism for energy production.
- Excretion of waste products.
- Reproduction for species continuation.
- Growth for organism development and maintenance.
