stomach | digestive system |
esophagus | digestion system. | muscles in the esophagus push your food to your stomach.
small intestine | digestive system |
large intestine | digestive system |
pancreas | digestive system |
liver | digestive system, circulatory system. |
kidneys | excretory system |
urinary bladder | excretory system |
muscles | muscular system |
bones | skeletal system |

Explanation:

To fill the "What it Does For my Body" column, we use biological knowledge of human organs:

• Brain (Nervous System): Controls thoughts, memory, emotions, and body functions (like movement, sensory processing).
• Heart (Circulatory System): Pumps blood to deliver oxygen and nutrients to cells, and remove waste.
• Lungs (Respiratory System): Facilitate gas exchange (oxygen in, carbon dioxide out) for respiration.
• Stomach (Digestive System): Mixes and breaks down food with acid and enzymes (mechanical/chemical digestion).
• Esophagus (Digestive System): Muscular tube that moves food from mouth to stomach (peristalsis, as partially filled).
• Small Intestine (Digestive System): Absorbs nutrients (sugars, proteins, fats) from digested food into the bloodstream.
• Large Intestine (Digestive System): Absorbs water and electrolytes; forms and stores feces.
• Pancreas (Digestive System): Produces digestive enzymes (for small intestine) and hormones (e.g., insulin to regulate blood sugar).
• Liver (Digestive + Circulatory Systems): Filters blood, produces bile (aids fat digestion), stores nutrients, detoxifies.
• Kidneys (Excretory System): Filter blood to produce urine (removes waste, regulates fluid/electrolyte balance).
• Urinary Bladder (Excretory System): Stores urine until elimination.
• Muscles (Muscular System): Enable movement (voluntary: limbs; involuntary: organs like heart/stomach), maintain posture.
• Bones (Skeletal System): Provide structure, protect organs (e.g., ribcage), produce blood cells, store minerals.

Answer:

Organ	Which System?	What it Does For my Body
Heart	Circulatory System	Pumps blood to deliver oxygen/nutrients and remove waste.
Lungs	Respiratory System	Facilitates gas exchange (O₂ in, CO₂ out) for respiration.
Stomach	Digestive System	Mixes/breaks down food with acid/enzymes (mechanical/chemical digestion).
Esophagus	Digestive System	Moves food from mouth to stomach (peristalsis, as started).
Small Intestine	Digestive System	Absorbs nutrients (sugars, proteins, fats) into the bloodstream.
Large Intestine	Digestive System	Absorbs water/electrolytes; forms/stores feces.
Pancreas	Digestive System	Produces digestive enzymes (for small intestine) and hormones (e.g., insulin).
Liver	Digestive/Circulatory	Filters blood, produces bile (fat digestion), stores nutrients, detoxifies.
Kidneys	Excretory System	Filters blood to produce urine (removes waste, regulates fluid/electrolyte balance).
Urinary Bladder	Excretory System	Stores urine until elimination.
Muscles	Muscular System	Enable movement (voluntary/involuntary), maintain posture.
Bones	Skeletal System	Provide structure, protect organs, produce blood cells, store minerals.
