Questions and Answers
What is homeostasis?
Organism's ability to maintain steady internal conditions while the outside conditions change.
How does the skeletal system maintain homeostasis?
By supplying calcium and working with the muscular system to move away from unpleasant stimuli.
What role does the muscular system play in maintaining homeostasis?
It contracts to turn chemical energy into thermal energy when the body is cold and manages oxygen delivery to cells.

Study Notes
Homeostasis
- Ability of organisms to maintain stable internal conditions despite external changes.
Skeletal System
- Supplies calcium essential for various bodily functions.
- Works with muscular system to facilitate movement away from harmful stimuli.
Muscular System
- Converts chemical energy into thermal energy to generate heat when the body is cold.
- Adjusts contraction frequency to optimize oxygen delivery from the heart to cells.
Integumentary System
- Produces vitamin D, crucial for calcium absorption.
- Protects against environmental hazards, preventing injury and infection.
- Regulates body temperature by facilitating cooling methods.
Digestive System
- Ensures sufficient nutrient absorption to support cellular functions.
- Eliminates waste products to maintain internal balance.
Excretory System
- Filters blood to remove waste, keeping the internal environment clean.
- Regulates fluid levels to prevent dehydration or overhydration.
Respiratory System
- Delivers oxygen to the bloodstream essential for cellular respiration.
Circulatory System
- Transports nutrients and hormones throughout the body.
- Collaborates with respiratory system for gas exchange of oxygen and carbon dioxide.
- Works with digestive system for nutrient distribution.
- Coordinates with endocrine system for hormone transport and regulation.
- Interacts with nervous system to maintain heart rate stability.
Lymphatic System
- Regulates fluid buildup to prevent tissue swelling.
- Plays a crucial role in immune defense against infections.
Immune System
- Produces antigens to protect the body from pathogens and maintain health.
Nervous System
- Monitors external stimuli and sends signals to enact physiological responses for homeostasis.
Reproductive System
- Ensures species survival but indirectly contributes to homeostasis through population management.
Endocrine System
- Releases hormones in reaction to various stimuli, establishing a system of feedback loops for internal regulation.
