Body Systems Working Together
Grade 7 · Science · Cells and Body Systems · Manitoba, Canada
Lesson Summary
See how the body's major systems depend on each other to keep you healthy.
Explanation
No body system works alone. The circulatory system delivers oxygen from the respiratory system and nutrients from the digestive system to every cell. The muscular and skeletal systems work together to create movement, guided by signals from the nervous system. The excretory system removes waste produced by all these processes. When one system is weakened by illness or injury, other systems are affected too, which is why overall health depends on every system functioning well.
Practice Questions
Q1: How do the respiratory and circulatory systems work together?
Answer: The respiratory system brings oxygen into the lungs, and the circulatory system transports that oxygen through the blood to cells throughout the body.
Q2: Give an example of the nervous system and muscular system working together.
Answer: When you decide to pick up a book, your brain (nervous system) sends a signal through nerves to your arm muscles (muscular system), telling them to contract and move your hand.
Q3: What might happen if the digestive system stopped functioning properly?
Answer: Other systems would be affected because the body would not be able to break down food into the nutrients that cells need for energy and repair.
