Chapter 9- Minerals Flashcards
What are the roles of water in the body?
Transportation of nutrients and waste products, fluid balance, thermal regulation, chemical reactions, maintaining homeostasis, solvent, clean tissues pf waste products, lubricant for joints, shock absorber, 50-60% of body weight
What is osmosis?
Fluid moving across semipermeable membrane/diffusion of water. Molecules go from high concentration to low concentration
What is concentration?
Number of molecules per volume
What are the functions of calcium?
MAJOR mineral, 99% in bones and teeth, normal bone structure and strength, blood calcium levels, maintain BP, blood clotting, muscle contractions, an electrolyte, nerve transmission, activates enzymes
What are the symptoms of calcium deficiency?
Osteoporosis
What are the symptoms of calcium toxicity?
constipation, inhibits absorption of other minerals, kidney stones, excess blood calcium levels
What are food sources of calcium?
milk, cheddar cheese, dairy, fortified soy milk, spinach, almonds
What are the functions of Magnesium?
coenzyme, energy metabolism, metabolism of calcium, vitamin D, Vitamin K, and cells use of energy
What are food sources of Magnesium?
Nuts, legumes, whole grain, green vegetables
What are the functions of Sodium?
Fluid balance, primary electrolyte outside of the cells, maintaining acid base balance, muscle contractions, nerve transmission, glucose transport
What are symptoms of Sodium toxicity?
Increases BP, hypertension (over 2300mg)
What are food sources of Sodium?
Processed foods!
What are the functions of Potassium?
Primary electrolyte inside of the cell, fluid balance, muscle contractions, nerve transmission, regulate heart rate
What are the food sources of potassium?
Fruits and vegetables, beans, milk, whole grains, meat, yogurt
What are the functions of Iodine?
Formation of thyroid hormones (BMR, temp regulation, reproduction)
What are the symptoms of Iodine deficiency?
Hypothyroidism, Goiter (enlarged thyroid gland), cretinism (mental and physical delays)
What are food sources of Iodine?
Milk, Iodized salt, seafood
