Interacting Body Systems — Drills · Grade 10 Science
Chapter: Body Systems, Signals & HomeostasisWhat these drills covers
By the end of Interacting Body Systems you should be able to:
- I can trace matter through digestive, respiratory, circulatory, and excretory systems.
- I can connect specialized exchange structures with the needs of cells.
2 questions, written answer, each with a worked explanation.
Vocabulary used: tissue, organ, gas exchange.
Problem 1
Why does naming an organ alone not explain a body function?
Answer and explanation
The mechanism also depends on its tissues, exchange surfaces, transport, and interactions with other systems.
Problem 2
Draw a route for carbon dioxide from a body cell to the environment.
Answer and explanation
Cell → tissue fluid/blood → circulation → lung capillaries → alveolar air → exhaled air; diffusion crosses the exchange barriers.
