UNIT 1- MY SELF THE FOOD YOU EAT THE 3 MACH NUTRIENT CATEGORIES FOR HUMAN DIGESTION ARE: CARBOHYDRATES, FATS, PROTEIN DIGESTIVE SYSTEM IS RESPONSIBLE FOR DIGESTING FOOD: 1) PHYSICALLY BREAKING DOWN. FOOD INTO NUTRIENTS ii) ABSORBING WATER AND NUTRIENTS (ii) PRODUCING WASTE FROM THE STUFF 1~ CE INTESTINES DON'T NEED DIGESTIVE SYSTEM IS MIDE UP OF ORGANS: MOUTH ESOPHOGUS STOMACH SMALL INTESTINE LARGE INTESTINE RECTUM/ANUS (IN ORDERR) STOMACH CHEMISTRY 15 WHEN INDIGESTION STOMACH ACID IS STRONGER THAN NORMAL (USUALLY FOOD-RELATED), AND IT BURNS/HURTS THE ESOPHAGUS ANTACIDS CONTAIN BASIC SUBSTANCES THAT NEUTRALIZE THE STOMACH ACID ACCOS NEUTRAL (WATER) BASES pH SCALE: 0 MORE CESS LESS ACIDIC STOMACH ACID ACIDIC 7 BASIC ANTACID MORE BASIC 14 (HCL) WHEN AN ACID REACTS WITH BASE, THEY CREATE AND WATER (Al(OH)3) A NEVTRAL COMPOUND OF A SALT ACIDS MOST AND BASES HAVE DIFFERENT PROPERTIES AND USES CLEANING SUBSTANCES WERE BASIC COMPOUNDS (LAUNDRY DETERGENT, TOILET BOWL CLEANER) THE AIR YOU BREATHE THE EARTH'S ATMOSPHERE NITROGEN 78% OF GASES SURROUNDING THE EARTH: ARGON, CARBON DIOXIDE, HYDROGEN, METHANE, HELIUM, WATER VAPOUR 0.93% 15 A COLLECTION OXYGEN 21% ALMOST 100% VERY LITTLE BITS THE RESPIRATORY SYSTEM IS A COLLECTION OF ORGANS: TRACHEA LUNGS THE RESPIRATORY SYSTEM TO BLOOD, AND FOR RESPONSIBLE IS BREATHING FOR BREATHING IN AIR, GIVING OXYGEN CARBON DIOXIDE THE SMALL STUFF SPECIALIZED GROUPS OF CELLS PERFORM SPECIALIZED SPECIFIC JOBS 2 OF A CERTAIN TYPE FORM THE BODY, "TISSUES" AND ORGANELLES ARE VERY SMALL STRUCTURES INSIDE EACH CELL EACH ORGANOLLE PERFORMS bey. THE NUCLEUS IN A SPECIFIC TASK INSIDE THE CELL ANY TYPE OF CELL CONTAINS GENETIC INFO. ex. THE MITOCHONDRIA IN ANY CELL PRODUCES ENERGY FOR THE CELL ex. THE VACUORE STORES WATER FOR THE CELL (DNA) BIOLOGICAL DRAWINGS ARE HAND DRAWN REPRESENTATIONS OF CELLS UNDER A MICROSCOPE AT HIGHER MAGNIFICATION ONION CELL AT 400X MAGNIFICATION RULES CELL WALL NUCLEUS RIBOSOME VACUOLE FOR BIOLOGICA DRAWINGS DONE WITH PENCIL ON BLANK PAPER . USE A BULER TO UNDERLINE TITLE & DRAW LINES LAGELS IN A COLUMN an RIGHT SIDE HORIZONTAL, PARALLEL LINES THAT DO NOT CROSS INCLUDE MAGNIFICATION & SPECIMEN TYPE IN TIRE USE ONLY STIPPLING, NOT SHADING THE CELL CYCLE
