Answer Key

#	Answer
1	Examples: circulatory system—moves blood; respiratory system—brings in oxygen and removes carbon dioxide; digestive system—breaks down food and absorbs nutrients.
2	Cells are the basic units of life that carry out the body’s functions and make up tissues.
3	A tissue is a group of similar cells working together, while an organ is made of different tissues working together for a specific function.
4	Homeostasis keeps internal conditions stable, such as temperature, pH, and water balance, so body systems can work properly.
5	The respiratory system brings oxygen into the lungs, and the circulatory system carries that oxygen in the blood to body cells while removing carbon dioxide.
6	Enzymes speed up chemical reactions that break food into smaller molecules the body can absorb and use.
7	The small intestine has a large surface area, and villi add even more surface area so nutrients can be absorbed efficiently into the blood and lymph.
8	Blood enters the right atrium, moves to the right ventricle, goes to the lungs, returns to the left atrium, moves to the left ventricle, and is pumped to the body.
9	The left side must pump blood to the entire body at higher pressure, while the right side only pumps blood to the lungs.
10	Arteries carry blood away from the heart, veins carry blood back to the heart, and capillaries allow exchange of gases, nutrients, and wastes with tissues.
11	It detects stimuli, processes information in the brain and spinal cord, and sends nerve signals to muscles and organs for a rapid response.
12	The nervous system provides fast electrical responses, while the endocrine system uses hormones for slower, longer-lasting regulation; together they coordinate body functions.
13	The kidneys filter the blood, remove wastes, regulate water and salt levels, and help control blood pressure and pH.
14	It recognizes specific surface markers and signals; immune cells identify pathogens as foreign and respond by attacking or neutralizing them.
15	Body systems are interdependent. For example, if the respiratory system is damaged and oxygen levels drop, the circulatory system carries less oxygen, muscles produce less energy, and the nervous system may also function less effectively.
