Intracellular digestion

Occurs within cell in unicellular or small multicellular

1

Extra cellular

Occurs outside cell in multicellular

2

Essential amino acids

8 that your body can't produce, include them in diet b/c they make proteins

3

Vitamins

Co-enzymes, important in chem reactions in body

4

Vitamin C

Neurotransmitters, hormones, prevents disease/cancer; deficiency causes scurvy; sources are citrus/berries leafy green veggies/peppers and tomatoes

5

Vitamin K

BLOOD CLOTTING; deficiency causes bruising and slow blood clotting; cooked dark veggies kiwi olive oil

6

Vitamin A

Skin/mucus/membranes/digestive lining; carotenoids, milk, dark veggies

7

Vitamin B-1 (Thiamine)

Coenzyme for carb metabolism; heart disease, BeriBeri, Alzheimer's; whole grain, lean pork, legumes

8

Calcium

Bone growth; osteoporosis, hypertension, colon cancer; dairy products, kale/broccoli

9

Iodine

Metabolism; goiter impairs growth and neurology development; soil/salt

10

Iron

Carries o2 and forms hemoglobin; anemia, low hemo and birth weight in babies; grain products, meat, poultry, fish

11

Zinc

Present in nucleus/major role in regulation; reduced immune function, skin lesions, depressed growth; red/white meat, shellfish

12

Malnourishment

Eat enough but eat unhealthy

13

Undernourishment

Don't even eat mannn

14

Mouth

Mechanical digestion, chewing, chemical digestion of carbs

15

Esophagus

No digestion, peristalsis moves food down

16

Stomach

Protein digestion

17

Pancreas

Make enzymes released to small int to break down carbs, lipids, proteins, accessory organ

18

Small intestine

Digestion of cabs, lipids and proteins, absorption of digested materials through villi

19

Large intestine

Reabsorption of water by villi

20

Liver

Makes bile to emulsify fat (NOT ENZYME) accessory organ

21

Epiglottis

Prevents food from going down wrong pipe

22

Peristalsis

Muscle contraction moves food involuntarily through digestive tract

23

Villi

Finger like projections in SMALL INTESTINE that INCREASE SURFACE AREA for greater absorption of fatty acids glycerol monosaccharides and amino acids. Surrounded by blood vessels to absorb/carry away nutrients (capillary w/ lymph node running through)

24

Gall bladder

Stores bile

25

3 macronutrients

Carbs (mono saccharide) proteins (amino) lipids (3 fatty acids+glycerol)

26

Bile

Made in liver stored in gall bladder (MECHANICAL EMULSIFYER, NOT ENZYME) fat globules->droplets

27

Trypsin

Basic (small int)

28

Pepsin

Acidic (stomach)

29

Ulcer

Bacteria, heliobacter pylori; pain and vomiting; causes erosion of surface; treatments are antacids, special diet, antibiotics

30

Colon cancer

Lack of calcium, obesity, genes; symptoms (often none besides diarrhea/constipation); causes fatigue, abdominal pain; chemo

31

Diarrhea

Intestinal infection; keep hydrated or use antibiotics

32

Gallstones

Small hard particles in gall bladder blocking bile duct; remove gall bladder
