Answer Key

#	Answer
1	The skeletal system supports the body, protects organs, and helps the body move.
2	The lungs help you breathe.
3	The heart pumps blood through the body.
4	Muscles need bones because they pull on them to help the body move.
5	The brain controls body activities, thoughts, and many actions.
6	The skin is an organ because it has important jobs such as protecting the body and helping control temperature.
7	The lungs put oxygen into the blood, and the heart pumps that oxygen-rich blood to the body.
8	The digestive system breaks down food so the body can use the nutrients for energy and growth.
9	Cells need oxygen to release energy from food and stay alive.
10	Voluntary muscles are muscles you control, while involuntary muscles work without you thinking about them.
11	Exercise makes muscles stronger and helps bones stay healthy and strong.
12	We need joints because they connect bones and allow movement.
13	The body cools itself mainly by sweating and sending more blood to the skin.
14	Red blood cells carry oxygen from the lungs to the rest of the body.
15	The nervous system sends messages quickly so the body can react to changes or danger.
16	Food provides nutrients, and oxygen helps cells break down those nutrients to release energy.
17	Their bones may become weaker and not develop as strongly.
18	The stomach breaks food into smaller pieces, and the small intestine absorbs nutrients from the food.
19	The brain needs oxygen and nutrients to work properly and control the body.
20	It carries waste products away from cells in the blood so they can be removed by other organs.
21	The skin helps protect the body, and blood cells and platelets help stop bleeding and start repair.
22	Body systems must work together because each system depends on the others to keep the body healthy and functioning.
23	Poor sleep can make it harder for the brain to focus and for the body to repair itself.
24	The respiratory system brings in oxygen, the circulatory system delivers it to muscles, and the muscular system uses that oxygen to move the body.
25	The human body is a system of connected parts because organs and body systems depend on one another to keep the body alive, healthy, and balanced.
