Respiration & the Human Body Systems
Respiration & the Human Body Systems The formula and illustrations must be aligned exactly as shown below. Oxygen + Food Energy + Wastes ATP (Energy) + Carbon dioxide + Water Oxygen + Glucose All Body Cells Respiratory Digestive Circulatory Excretory
Respiratory System Brings oxygen into the body
Digestive System Digests food – breaks it down into smaller nutrient molecules Absorbs nutrient molecules into the bloodstream
Circulatory Systems Transports substances, such as glucose, oxygen, and carbon dioxide throughout the body
All Body Cells Mitochondria – site of cellular respiration Occurs in all body cells ATP = stored energy Some cells need more energy than others. Which ones?
Excretory System Removes wastes: Lungs* – carbon dioxide and water Kidneys – urea and water Skin – perspiration (water & chemical wastes) *part of cellular respiration process
