Study Notes
Levels of Organization
- Organelle: Organized structures within a cell, known as "little organs," each with distinct shapes and functions.
- Cell: The fundamental unit of life, serving as the basic structure and functional unit in organisms.
- Tissue: Group of similar cells organized to perform specialized functions.
- Organ: Comprised of two or more tissue types that collaborate to perform specific, complex tasks.
- Organ System: A group of related organs working together to coordinate functions for a common purpose.
- Organism: The highest level of organization, representing a complete living entity, such as a human.
The 11 Organ Systems
- Integumentary System: Includes skin, hair, nails, and sweat glands.
- Skeletal System: Composed of bones, cartilage, and ligaments.
- Muscular System: Consists of skeletal, smooth, and cardiac muscles.
- Nervous System: Encompasses the brain, spinal cord, and peripheral nerves.
- Endocrine System: Composed of glands like the pituitary, thyroid, and adrenal glands.
- Cardiovascular System: Includes the heart and blood vessels.
- Lymphatic System: Features lymph nodes, spleen, and thymus.
- Respiratory System: Consists of lungs, trachea, and bronchi.
- Digestive System: Comprises the stomach, intestines, and liver.
- Urinary System: Includes kidneys and bladder.
- Reproductive System: Divided into male and female components.
Definitions
- Organ: Two or more tissue types working together for complex functions.
- Organ System: A collection of organs that work in tandem to achieve a common function.
Homeostasis
- Homeostasis: Mechanisms that maintain stable conditions within the body.
- Example: Regulation of body temperature through blood circulation in the integumentary system.
Multiple Choice Review
- Midsaggital section separates the right and left halves of the body.
- Recognizing the heart under the sternum relates to surface anatomy.
- The forearm region is termed antebrachial.
- Constant internal environment is termed homeostasis.
- The level of organization consisting of two or more tissue types is an organ.
- The cavity beneath the diaphragm is the abdominal cavity.
- A structure located below another is termed inferior.
- The organ system that filters waste is the urinary system.
- The anterior portion of the knee is referred to as patellar.
- The membrane covering the lungs is the visceral pleura.
- Cytology focuses on cell study, while histology focuses on tissue study.
- Anatomy studies structure, while physiology examines function; e.g., the small intestine's role in food breakdown.
- Steps in the scientific method include gathering information and forming hypotheses, used by clinicians in patient care.
