Worksheet Overview & Skills Covered

Core academic competencies and curriculum alignment

This Biology Science worksheet provides structured practice on 10.103 Respiratory and Circulatory System Integration. Students are guided through targeted exercises that build foundational understanding, computational accuracy, and critical thinking skills.

Respiratory and Circulatory System Integration: Students interpret how respiratory surfaces, blood, hemoglobin, capillaries, the heart, and concentration gradients support gas exchange and transport across multiple body systems. Rigor range: standard concept checks through honors/Pre-AP/AP-ready integrated physiology, plant systems, health data, and applied decision-making.

Below are sample questions representative of the exercises included on this worksheet and related 10.103 Respiratory and Circulatory System Integration skill assessments:

Problem 1Difficulty: Mastery

After repeated sprints, a student has high breathing rate, high heart rate, and rising lactate levels. Which integrated explanation best fits these observations?

AThe lungs produced lactate because alveoli use fermentation as their main energy source.

BHigh heart rate proves oxygen demand was low and carbon dioxide production stopped.

CLactate rises only when hemoglobin carries too much oxygen to tissues.

DOxygen demand in active muscle exceeded aerobic delivery for part of the activity, so anaerobic metabolism increased while breathing and circulation responded.

Solution & Explanation:Sprints can require ATP faster than oxygen delivery supports fully aerobic respiration, so lactate rises while respiratory and circulatory responses try to meet demand.

Problem 2Difficulty: Mastery

A model shows three lung units: Unit 1 has matched airflow and blood flow, Unit 2 has high airflow but low blood flow, Unit 3 has low airflow but high blood flow. Which unit should contribute most efficiently to oxygenating blood?

AUnit 2, because airflow alone oxygenates blood even without perfusion.

BUnit 3, because blood flow alone oxygenates blood even without ventilation.

CUnit 1, because ventilation and perfusion are matched for exchange.

DUnits 2 and 3, because mismatches always increase diffusion gradients.

Solution & Explanation:Efficient gas exchange requires both air and blood near the respiratory surface; matched ventilation and perfusion provide that condition.

Problem 3Difficulty: Mastery

Which plant-animal comparison avoids a misleading analogy?

APlants have pulmonary arteries that carry oxygen from roots to lungs.

BPlants regulate gas exchange with stomata and move water/sugars in vascular tissue, but they do not use blood to transport most gases.

CPlants use hemoglobin in phloem to bind carbon dioxide for photosynthesis.

DPlants and mammals both require a heart to move gases through leaves and lungs.

Solution & Explanation:Plant vascular tissues move water and sugars, while gases mainly diffuse through stomata and air spaces; animals often use blood for gas transport.
