PG 34A Essential Question   What are the interactions that occur among the systems that perform the function of nutrient absorption? 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

What nutrients are needed for your body to function? Food (carbohydrates, lipids, proteins, vitamins, minerals) Water Oxygen

SYSTEMS INVOLVED DRAW ALL OF THIS. NUTRIENT ABSORPTION Digestive Respiratory Circulatory DRAW ALL OF THIS.

DIGESTIVE SYSTEM Main Parts: Mouth Esophagus Stomach Small intestine Large intestine

Getting & Using Food Ingest Digest Absorb Eliminate taking in food mechanical digestion breaking up food into smaller pieces chemical 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 intracellular digestion 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 stomach kills germs break up food digest proteins store food pancreas produces enzymes to digest proteins and starch

mouth break up food digest starch kill germs moisten food stomach kills germs break up food digest proteins store food liver produces bile - stored in gall bladder break up fats pancreas produces enzymes to digest proteins & starch

mouth break up food digest starch kill germs moisten food stomach kills germs break up food digest proteins store food liver produces bile - stored in gall bladder break up fats small intestines breakdown food - proteins - starch - fats absorb nutrients pancreas produces enzymes to digest proteins and starch

mouth break up food digest starch kill germs moisten food stomach kills germs break up food digest proteins store food liver produces bile (stored in gall bladder) break up fats small intestines breakdown food - proteins - starch - fats absorb nutrients pancreas produces enzymes to digest proteins and starch 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 Artery to Head and Body Vein from Head and Body Vein from Lungs Right Atrium Left Atrium valve valve Left Ventricle Right Ventricle

8.8 Title: Blood flow in the heart. Caption: (c) Blood flows through the heart from the atria to the ventricles.

what’s in BLOOD digested food red blood cells white blood cells oxygen waste (urea) platelets carbon dioxide plasma hormones

a biconcave disc that is round and flat without a nucleus Red Blood Cells contain hemoglobin, a molecule specially designed to hold oxygen and carry it to cells that need it. a biconcave disc that is round and flat without a nucleus 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 cells take up glucose from blood pancreas insulin depress appetite liver takes up glucose for storage liver releases glucose to blood pancreas stimulate hunger glucagon

DEBRIEF: Quickwrite in Bellwork Journal: Explain how all three systems work together for nutrient absorption in the body.
