Digestive System Sample Footer Text 2/8/20 XX 3

Digestive System Functions • Digestion: the breakdown of food into molecules that can be absorbed by the body • Absorption • Responsible for maintaining homeostasis Sample Footer Text 2/8/20 XX 4

Parts of the Digestive System • Digestive tract: mouth, pharynx, esophagus, stomach, small intestine, large intestine • Accessory organs: teeth, tongue, salivary glands, liver, gallbladder, pancreas Sample Footer Text 2/8/20 XX 5

Organs of the Digestive System • Stomach: digestion • Pharynx: throat • Esophagus: tube from mouth to stomach, inside pharynx • Small intestine: absorbs nutrients • Large intestine: absorbs water and salts Sample Footer Text 2/8/20 XX 6

Accessory Organs in the Digestive System • Liver: creates bile which helps break down fats • Gallbladder: stores bile • Pancreas: creates enzymes which break down fats, starches, and sugars Sample Footer Text 2/8/20 XX 7

Digestive System and Maintaining Homeostasis • Toxin Excretion – indigestible materials Sample Footer Text 2/8/20 XX 8

Respiratory System Sample Footer Text 2/8/20 XX 9

Respiratory System Function • Breathing • Absorb oxygen from the air • Remove carbon dioxide from the blood • Responsible for maintaining homeostasis Sample Footer Text 2/8/20 XX 10

Respiratory System Organs • Nose and mouth • Pharynx: throat • Larynx: voice box • Trachea: windpipe • Bronchi: airways • Lungs Sample Footer Text 2/8/20 XX 11

Respiratory System and Homeostasis • Body temperature: exhaling warm air • Toxin excretion: carbon dioxide • p. H balance Sample Footer Text 2/8/20 XX 12

Circulatory System Sample Footer Text 2/8/20 XX 13

Circulatory System Function • Carries oxygen, nutrients, and hormones to cells • Removes waste products • Responsible for maintaining homeostasis Sample Footer Text 2/8/20 XX 14

Circulatory System Organs • Heart: pumps blood around body • Blood: delivers nutrients and oxygen all over the body • Blood vessels: carries blood around body • Lymph: cleanses out fluid, removes dead cells and cancer cells • Lymphatic vessels: help maintain fluid balance Sample Footer Text 2/8/20 XX 15

What is the difference between arteries and veins? • Veins: carry blood back to the heart • Arteries: carry blood away from the heart Sample Footer Text 2/8/20 XX 16

Circulatory System and Homeostasis • Body temperature: sweat • Blood pressure regulation Sample Footer Text 2/8/20 XX 17

Circulatory system lab • Follow directions on the lab worksheet • Turn it in at the end of the class, if you are not done it is homework (Due by Tuesday, 4/13) • Do not lose the worksheet, you may need it for your lab report • We will discuss the lab report on Wednesday (4/14) Sample Footer Text 2/8/20 XX 18
