HAPPY MONDAY WELCOME BACK!!! C3 computer Bellwork: A.Quickwrite (54 words – attach a sheet of paper if necessary): What body systems are involved with nutrient absorption? Defense against illness or injury? Regulation/control of your body? And reproduction?

Monday Digestive Circulatory Respiratory Tuesday Immune Integumentary Wednesday Nervous Muscular Skeletal Thursday Reproductive Endocrine Excretory Essential Question PG 124 How do animal systems interact to absorb nutrients? Standard B.10A - describe the interactions that occur among systems that perform the functions of regulation, nutrient absorption, reproduction, and defense from injury or illness in animals Presentations What nutrients are needed for your body to function? •Food (carbohydrates, lipids, proteins, vitamins, minerals) •Water •Oxygen SYSTEMS INVOLVED NUTRIENT ABSORPTION Digestive Respiratory DRAW ALL OF THIS. Circulatory DIGESTIVE SYSTEM • Main Parts: • Mouth • Esophagus • Stomach • Small intestine • Large intestine Getting & Using Food • Ingest • taking in food • Digest • mechanical digestion • breaking up food into smaller pieces • chemical digestion intracellular digestion • breaking down food into molecules small enough to be absorbed into cells using enzymes • Absorb • absorb nutrients across cell membranes • diffusion • active transport • Eliminate • undigested material passes out of body extracellular digestion Digestive systems Everybody’s got one! mouth break up food digest starch kill germs moisten food stomach kills germs break up food digest proteins store food sphincter sphincter mouth break up food digest starch kill germs moisten food pancreas produces enzymes to digest proteins and starch stomach kills germs break up food digest proteins store food mouth break up food digest starch kill germs moisten food liver produces bile - stored in gall bladder break up fats pancreas produces enzymes to digest proteins & starch stomach kills germs break up food digest proteins store food mouth break up food digest starch kill germs moisten food liver produces bile - stored in gall bladder break up fats pancreas produces enzymes to digest proteins and starch stomach kills germs break up food digest proteins store food small intestines breakdown food - proteins - starch - fats absorb nutrients mouth break up food digest starch kill germs moisten food liver produces bile (stored in gall bladder) break up fats pancreas produces enzymes to digest proteins and starch stomach kills germs break up food digest proteins store food small intestines breakdown food - proteins - starch - fats absorb nutrients large intestines reabsorb water DIGESTIVE SYSTEM • Main Functions: • Mouth breaks down food into smaller pieces • Stomach enzyme breaks food into biomolecules (carbs, lipids, proteins) • Small intestine breaks food into monomers and absorbs nutrients • Large intestine reabsorbs water Lung Inflation! How Lungs Work! RESPIRATORY SYSTEM • Main Parts: • Nose • Mouth • Lungs • Diaphragm RESPIRATORY SYSTEM • Main Functions: • Nose & mouth filter air as it comes in • Diaphragm contracts and relaxes to move the lungs • Lungs expand and contract for inhaling & exhaling • Oxygen diffuses into blood • Oxygen necessary to release energy from food (glucose) Circulatory System CIRCULATORY SYSTEM • Main Parts: • Blood vessels • Heart • Red blood cells The Heart Artery to Lungs Vein from Head and Body Right Atrium valve Right Ventricle Artery to Head and Body Vein from Lungs Left Atrium valve Left Ventricle what’s in digested food red blood cells white blood cells oxygen waste (urea) platelets carbon dioxide plasma hormones Red Blood Cells a biconcave disc that is round and flat without a nucleus contain hemoglobin, a molecule specially designed to hold oxygen and carry it to cells that need it. can change shape to an amazing extent, without breaking, as it squeezes single file through the capillaries. CIRCULATORY SYSTEM • Main Functions: • Heart pumps blood through blood vessels • Transports oxygen & carbon dioxide to and from the respiratory system • Transports nutrients from the digestive system to the rest of the body INTERACTION: Maintaining Homeostasis • Balancing glucose levels in blood depress appetite pancreas insulin cells take up glucose from blood liver takes up glucose for storage liver releases glucose to blood glucagon pancreas stimulate hunger DEBRIEF: Explain how all three systems work together for nutrient absorption in the body.
