Digestive, Circulatory, and Respiratory Systems Cellular Respiration Digestive, Circulatory, and Respiratory Systems

Cellular Respiration Is the set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products Formula C6H12O6 + 6O2 6CO2 + 6H2O + ATP Glucose +Oxygen Carbon Dioxide + Water + Energy

Cellular Respiration and Digestion Through the digestive system the body acquires the food it needs to fuel all cells .

Cellular Respiration and Digestion Main food source needed are carbohydrates broken into glucose molecules

Cellular Respiration and Digestion The cell breaks the glucose into something smaller and sends it off to the mitochondria there the mitochondria uses these smaller pieces with oxygen to make energy for you

Cellular Respiration and Circulatory The heart and vessels are responsible to pump and transport all nutrients to all parts of the body through tiny vessels called capillaries

Cellular Respiration and Circulatory Things like glucose, oxygen and carbon dioxide are able to enter or exit the tissue or vessel

Cellular Respiration and Circulatory The only way to get glucose (from the intestine) and oxygen (from the lung) to the cells of your toes is through blood vessels

Cellular Respiration and Circulatory The blood vessels are essential in removing waste products too, like carbon dioxide

Cellular Respiration and Respiratory The lungs are necessary to get oxygen into the body In the lungs there are millions of little air sacs called alveoli that are surrounded by capillaries here the blood drops off carbon dioxide and picks up oxygen

Cellular Respiration and Respiratory This oxygen will be taken directly to the cells when the oxygen gets to the cell The mitochondria takes it and begins the process of cellular respiration

62% is used as thermal energy to heat organism How Much Energy During this process 38% glucose is released as energy to complete life’s process 62% is used as thermal energy to heat organism

Dietary Needs For Cells

Dietary Needs For Cells Protein Essential to Diets They help rebuild and repair cells

Dietary Needs For Cells Fiber Keeps the digestive system working properly. Which is essential for cellular respiration

Dietary Needs For Cells Carbohydrates Essential for cellular respiration to convert to glucose for energy Grains provide a good source.
