Teacher Notes:
Use this worksheet as a warm-up, independent review, partner game, or quick assessment on the human body. Suggested classroom use: student race-to-complete, team points, or station review. Learning objectives: identify major body systems and organs, explain basic functions, and connect body structure to function. Skills practiced: recall, classification, matching, basic interpretation, and simple reasoning. Differentiation: support struggling learners with word banks or partner reading; challenge advanced learners with a brief oral explanation or extension question about how two systems work together.

18	Urinary system	The urinary system removes wastes and excess water through urine.
19	Respiratory system	Breathing increases so more oxygen can enter the body.
20	Tendons	Tendons attach muscles to bones.
21	Mouth, stomach, small intestine	Food is broken down in the mouth, processed in the stomach, and nutrients are absorbed in the small intestine.
22	Kidneys	Kidneys clean the blood and help maintain fluid balance.
23	Circulatory system	The circulatory system moves blood through the body.
24	False	Nerves send signals that help muscles contract and move.

26	Gallbladder	The gallbladder stores bile before it is used in digestion.
27	Immune system	White blood cells are key parts of the immune response.
28	Diaphragm	The diaphragm contracts to help air move into the lungs.
29	spinal cord	The spinal cord is the main pathway for signals between the brain and body.
30	Musculoskeletal system	Muscles pull on bones to create movement.
31	To deliver more oxygen and remove carbon dioxide faster	Exercise increases the body’s need for oxygen and waste removal.
32	Heart	The heart pumps blood throughout the body.
33	Stop bleeding and protect the wound	A scab helps protect the area while healing happens.
34	Digestive and circulatory systems	The digestive system breaks food down, and the circulatory system carries nutrients to cells.

39	Endocrine system	Insulin is a hormone made by the pancreas and used in blood sugar control.
40	organ system	Organs that work together form an organ system.
41	Nervous, muscular, and skeletal systems	The eyes and brain process information, and muscles and bones create the movement.
42	It keeps internal conditions stable	Homeostasis helps the body stay balanced, such as keeping temperature and water levels controlled.
43	Cerebellum	The cerebellum helps coordinate movement and balance.
44	A) More waste builds up in the blood	Kidneys remove wastes, so kidney problems can cause wastes to build up.
45	Gas exchange	Alveoli let oxygen enter the blood and carbon dioxide leave it.
46	Homeostasis	Thirst helps the body maintain water balance.
47	To allow exchange of gases, nutrients, and wastes	Thin walls make it easy for materials to move between blood and body cells.
48	Liver	The liver makes bile, which helps digest fats.
49	It delivers oxygen and nutrients to cells and removes wastes	Blood carries materials that cells need and helps remove carbon dioxide and other wastes.
50	Sample answer: Muscular system, because nerves tell muscles when to contract and move.	Many systems work with the nervous system; the key idea is that nerves send signals that control body actions.
