1 NOTES Inv. 2 Supporting Cells / / p. Food (energy) Delivery System into our Bodies Excretory System digestive breaks down food into molecules that cells can use nutrient molecules pass into the bloodstream through the small intestine the body gets its energy from the food we eat

2 NOTES Inv. 2 Supporting Cells / / p. Oxygen Delivery System into our Bodies cardiovascular refers to the circulatory blood picks up nutrients in the small intestine blood travels to the lungs after it picks up the nutrients the circulatory pumps blood throughout the body so that the blood can deliver oxygen and nutrients to the cells 3 types of blood vessels: arteries, veins, and capillaries Arteries carry blood Away from the heart; veins carry blood to the heart

3 NOTES Inv. 2 Supporting Cells / / p. Oxygen Delivery System into our Bodies oxygen transfers into the bloodstream from the lungs oxygen travels: through nose/mouth > through trachea > into lungs > into the bronchi > into the alveoli (air sacs) capillaries surrounding the air sacs are where the oxygen passes into the bloodstream

4 Investigation 2 Notes Supporting Cells 10/21/16 oxygen and nutrients are the two main resources that cells need to function and stay alive humans get nutrients from the foods/drinks that contain calories calorie: a unit that measures the amount of energy in food water, sleep, exercise, etc. are essential for cells and humans to function; but they do NOT provide energy for the cells the more physical activity our bodies do, the faster our heart pumps and the faster we breathe so the blood can get oxygen to the cells we can detect this by checking our pulse rate all cells need oxygen and nutrients

5 DEFINITION The process almost all cells use to turn food molecules and oxygen into energy to live and grow CHARACTERISTICS requires oxygen occurs in cells, both plant and animal cells carbon dioxide and water are the waste products EXAMPLE aerobic cellular respiration NON EXAMPLE In the human body, cells use glucose from the digestive and oxygen from the respiratory to obtain usable energy Photosynthesis plants capture energy from the Sun and use it to turn carbon dioxide and water into glucose and oxygen

6 Aerobic Cellular Respiration SUMMARY Digestive Circulatory (blood) Respiratory Food (glucose) TO CELLS Oxygen (O 2 ) AT CELLS (aerobic cellular respiration) C 6 H 12 O 6 + O 2 Energy + CO 2 + H 2 O Energy Waste water (H 2 O) FROM CELLS Carbon dioxide (CO 2 ) Excretory Circulatory (blood) Respiratory

7 Food enters the Digestive body through the mouth. Food enters the bloodstream. Circulatory (blood) Oxygen enters the body through the nose/mouth. Respiratory Oxygen enters the bloodstream. Food goes to the cells. Food (glucose) TO CELLS Oxygen (O 2 ) Oxygen goes to the cells. ENERGY is made!!! AT CELLS (aerobic cellular respiration) C 6 H 12 O 6 + O 2 Energy + CO 2 + H 2 O Energy Waste water (H 2 O) FROM CELLS Carbon dioxide (CO 2 ) H 2 O enters the bloodstream. Circulatory CO 2 enters the bloodstream. Excretory (blood) Respiratory Water is excreted from the body through the excretory. Water and CO 2 are excreted from the body through the respiratory.

8 Investigation 2 Notes Supporting Cells / / p. ~Big Ideas~ The human body is made of s, which are made of organs, which are made of tissues, which are made of cells All the human organ s interact in order for a human to live and carry out life functions. The most important function is servicing cells. In a human, the circulatory pumps blood, which carries resources to each cell and carries away waste. Cells use glucose and oxygen, provided by the digestive and respiratory s, to provide usable energy for the cell. This process is aerobic cellular respiration. Carbon dioxide and water are the waste products of aerobic cellular respiration and are removed by the respiratory and excretory s. Modeling s is useful to describe processes and construct explanations.
