Unit 8 Review - HBS, Homeostasis

What role does the muscular system play in homeostasis?

• It helps maintain posture and generates heat through movement.

• It regulates blood pressure and heart rate.

• It stores nutrients and minerals for the body.

• It facilitates the exchange of gases in the lungs.

How do the integumentary and circulatory systems work together?

• The integumentary system protects the body while the circulatory system delivers necessary components for healing.

• The integumentary system regulates body temperature while the circulatory system removes waste products.

• The integumentary system provides nutrients to the skin while the circulatory system transports oxygen to the muscles.

• The integumentary system absorbs sunlight while the circulatory system distributes hormones throughout the body.

What is the role of the circulatory system during long-distance running?

• It carries oxygen to the muscles.

• It removes carbon dioxide from the muscles.

• It regulates body temperature.

• It stores energy for muscle contraction.

What is the primary function of the nervous system?

• To transmit signals between different parts of the body.

• To produce hormones that regulate metabolism.

• To provide structural support to the body.

• To facilitate the exchange of gases in the lungs.

What is a negative feedback loop?

• A process where each action creates a consequence that decreases the other action.

• A mechanism that amplifies changes in a system.

• A method of increasing the output of a system.

• A strategy for maintaining constant conditions in a system.

What is an example of a stimulus that might disrupt homeostasis?

• Extreme temperature changes.

• Consistent room temperature.

• Regular exercise routines.

• Balanced diet.

What is homeostasis?

• The process of cell division.

• The maintenance of a stable internal environment in the body.

• The ability to adapt to external changes.

• The mechanism of energy production in cells.

What are the two body systems interacting when platelets seal a paper cut?

• Nervous and muscular systems

• Integumentary and circulatory systems

• Digestive and respiratory systems

• Endocrine and lymphatic systems

What is the relationship between the respiratory and circulatory systems?

• The respiratory system provides oxygen to the blood, which the circulatory system transports to cells.

• The circulatory system filters toxins from the blood before it reaches the lungs.

• The respiratory system removes carbon dioxide from the blood, which the circulatory system then expels from the body.

• The circulatory system is responsible for the production of red blood cells, while the respiratory system regulates blood pressure.

Which body system is responsible for gas exchange?

• Digestive system

• Respiratory system

• Circulatory system

• Nervous system
