How to use these flashcards

Work through these flashcards in short sessions. Try to answer each prompt before flipping the card, then revisit any cards you miss until the explanation feels automatic.

Flashcard 1: Identify the interaction: bones produce blood cells in marrow; which systems interact?

Answer: Skeletal and circulatory systems. Bone marrow produces blood cells that enter circulation.

Flashcard 2: Identify the feedback type: uterine contractions trigger oxytocin, increasing contractions.

Answer: Positive feedback. Response amplifies the initial stimulus in a self-reinforcing cycle.

Flashcard 3: Identify the interaction: insulin from pancreas lowers blood glucose; which systems interact?

Answer: Endocrine and digestive systems. Hormone from endocrine gland affects digestive system function.

Flashcard 4: What type of model best represents rates and directions of material movement among systems?

Answer: Flow model (inputs, outputs, and transfers). Shows how substances move between systems at specific rates.

Flashcard 5: What is the main transport medium linking organ systems in many interaction models?

Answer: Blood. Carries materials, signals, and wastes between different organ systems.

Flashcard 6: Identify the interaction: adrenaline increases heart rate via hormones; which systems interact?

Answer: Endocrine and circulatory systems. Hormone travels through blood to affect heart muscle.

Flashcard 7: Which two systems coordinate rapid and long-term signaling in interaction models?

Answer: Nervous and endocrine systems. Nervous provides fast signals, endocrine provides slower hormonal control.

Flashcard 8: Identify the interaction: motor neurons trigger muscle contraction; which systems interact?

Answer: Nervous and muscular systems. Neural signals directly stimulate muscle fiber contraction.

Flashcard 9: Identify the interaction: insulin from pancreas lowers blood glucose; which systems interact?

Answer: Endocrine and digestive systems. Hormone from endocrine gland affects digestive system function.

Flashcard 10: Identify the interaction: skin sweat glands cool the body under brain control; which systems interact?

Answer: Integumentary and nervous systems. Brain controls skin glands for temperature regulation.

Flashcard 11: Identify the interaction: lymph vessels return fluid to blood; which systems interact?

Answer: Lymphatic and circulatory systems. Lymphatic vessels drain excess tissue fluid back to bloodstream.

Flashcard 12: Which body systems interact to absorb nutrients and distribute them to cells?

Answer: Digestive and circulatory systems. Intestines absorb nutrients, blood distributes them throughout body.

Flashcard 13: Identify the interaction: white blood cells attack bacteria in tissues; which systems interact?

Answer: Immune and circulatory systems. Immune cells travel in blood to reach infection sites.

Flashcard 14: What does a receptor do in a model of system interactions maintaining homeostasis?

Answer: Detects a stimulus or change in a regulated variable. Sensors that monitor conditions and detect deviations from normal.

Flashcard 15: What are the three core parts of a homeostatic control model (in order)?

Answer: Receptor, control center, effector. The basic components of any homeostatic control system.

Flashcard 16: What is a set point in a homeostasis model involving multiple body systems?

Answer: The target value a regulated variable is maintained near. The optimal level that homeostatic mechanisms work to maintain.

Flashcard 17: What term in system models refers to keeping internal conditions within a narrow range?

Answer: Homeostasis. Maintains stable internal environment despite external changes.

Flashcard 18: Which type of feedback loop amplifies a change in models of biological interactions?

Answer: Positive feedback. Enhances the original stimulus, moving away from equilibrium.

Flashcard 19: Which type of feedback loop stabilizes internal conditions in system-interaction models?

Answer: Negative feedback. Counteracts changes to maintain stability and equilibrium.

Flashcard 20: What is a feedback loop in a model of interacting biological systems?

Answer: An output that influences the system’s input, changing the response. Creates a cycle where output affects input, modifying system behavior.

Flashcard 21: What is the difference between a structural model and a functional model of a biological system?

Answer: Structural shows parts; functional shows processes and interactions. Structural focuses on anatomy, functional focuses on physiological processes.

Flashcard 22: Which option best labels the effector in thermoregulation: sweat glands increase sweating?

Answer: Sweat glands. The structure that produces the cooling response.

Flashcard 23: Which option best labels the receptor in thermoregulation: skin detects temperature change?

Answer: Thermoreceptors in skin. The sensors that detect temperature changes in environment.

Flashcard 24: Which option best labels the control center in thermoregulation: brain integrates signals?

Answer: Hypothalamus. The brain region that processes temperature signals and coordinates response.

Flashcard 25: Identify the feedback type: blood glucose rises, insulin lowers it toward set point.

Answer: Negative feedback. Response opposes the initial change to restore normal levels.

Flashcard 26: Identify the feedback type: body temperature drops, shivering raises temperature.

Answer: Negative feedback. Shivering generates heat to counteract the temperature drop.

Flashcard 27: Which variable is being regulated in a model where ADH increases kidney water reabsorption?

Answer: Blood water concentration (osmolarity). ADH regulates water balance by controlling kidney water retention.

Flashcard 28: What is the main criterion for judging whether a biological interaction model is useful?

Answer: It accurately predicts outcomes within its stated assumptions. A good model successfully predicts real biological outcomes.

Flashcard 29: Which option best describes why models often omit details when showing system interactions?

Answer: To focus on key variables and causal relationships. Simplification highlights important interactions while reducing complexity.

Flashcard 30: Identify the correct model link: increased $CO_2$ in blood causes faster breathing; which systems interact?

Answer: Circulatory and respiratory systems. High $CO_2$ triggers respiratory response via circulatory detection.
