Below are sample questions representative of the exercises included on this worksheet and related 6.73 Human Body Systems and Interactions skill assessments:

Problem 1Difficulty: Mastery
A class is asked to choose the best overall model of the human body. Which model is most accurate?
AA model showing specialized cells forming tissues and organs, with multiple organ systems exchanging matter and signals to keep the body stable
BA model showing only bones because all body systems are made of bones
CA model showing one giant cell that does every job in the body
DA model showing each organ floating separately with no arrows or connections
Solution & Explanation:The most accurate model includes levels of organization and interactions among subsystems.
Problem 2Difficulty: Mastery
Use the model of a person riding a bicycle with labeled lungs, heart, leg muscles, skin, and brain connected by arrows. One arrow goes from the leg muscles toward the lungs. Which label would make that arrow most accurate?
Abone tissue
Bcarbon dioxide
Curine
Dsaliva
Solution & Explanation:Working muscle cells produce carbon dioxide, which is carried by blood to the lungs for removal.
Problem 3Difficulty: Mastery
Which evidence best supports the argument that body subsystems help maintain homeostasis after exercise?
ABones become longer immediately after running.
BBreathing and pulse gradually slow, sweating releases heat, and the body works to restore balance after activity ends.
CThe digestive system stops interacting with all other systems after movement.
DHair grows faster for a few minutes after exercise.
Solution & Explanation:Returning toward normal conditions after exercise shows interacting systems helping maintain homeostasis.
