Below are sample questions representative of the exercises included on this worksheet and related 7.27 Body System Pathways skill assessments:

Problem 1Difficulty: Mastery

A science poster is supposed to show the body as a system of interacting subsystems. Which description best meets that goal?

AA poster that lists organ names alphabetically without explaining any interactions

BA poster that focuses only on bones and muscles without showing transport

CA poster that labels body parts but shows no arrows or movement of materials

DA poster that shows digestive and respiratory inputs, circulatory transport to cells, and waste removal by respiratory and urinary pathways

Solution & Explanation:To show interacting subsystems, the model should include materials entering, being transported, being used by cells, and leaving through waste pathways.

Problem 2Difficulty: Mastery

Why do heart rate and breathing rate often stay elevated for a short time after exercise ends?

AThe bladder stores extra air after exercise and slowly releases it through the kidneys.

BThe circulatory and respiratory systems continue delivering oxygen and removing carbon dioxide while cells recover from activity.

CThe bones keep using all oxygen for several minutes, so the lungs have to pump harder.

DThe digestive system keeps making extra carbon dioxide after movement stops, and only the stomach can remove it.

Solution & Explanation:Recovery takes time. Body systems continue transporting materials and clearing wastes after intense muscle activity stops.

Problem 3Difficulty: Mastery

A branching diagram is meant to show that once molecules enter the blood, they can have different fates. Which branch set is most accurate?

Ablood -> mouth for filtration; blood -> small intestine for exhalation; blood -> ribs for digestion

Bblood -> bones for breathing; blood -> stomach for thinking; blood -> skin for digestion

Cblood -> cells for growth and energy release; blood -> kidneys for waste removal; blood -> lungs for gas exchange

Dblood -> bladder for oxygen loading; blood -> muscles for urine storage; blood -> lungs for bone growth

Solution & Explanation:Once materials are in the blood, different body systems can use, exchange, or remove them depending on the molecule and body need.
