A

Movement of water from an area of low salt concentration to an area of high solute concentration through a membrane

34
Q

What solutes influence osmosis

A

Electrolytes (sodium, potassium, and chloride)

Protein

35
Q

How do we excrete water?

A

Kidney - urine

GI tract - feces

Skin - sweat

Insensible losses - drying of skin, moisture lost through breathing

36
Q

How many liters are lost daily

A

2-3 liters

*Can change based on activity, temperature, and humidity*

37
Q

Oral rehydration therapy

A

The act of providing water and electrolytes to reverse dehydration

38
Q

Water-soluble vitamins

A

Vitamin C, B vitamins

Readily excreted in H2O

Not stored

Not toxic

Defficiencies quickly onset due to high excretion

39
Q

Fat-soluble vitamins

A

A, D, E, K

Not readily excreted

Stored in the body (fat, liver, skin)

Highly toxic

Deficiencies develop slowly due to high storage levels

40

A

True

42
Q

Vitamins can be created by plants and animals

Protein - sulfur amino acids

46
Q

Trace Minerals

A

Iron, copper, zinc, iodine, and selenium

47
Q

Zinc

A

Cell replication and division - would healing

Defiency - poor growth and would healing, poor immune response

48
Q

Iron

A

Component of myoglobin (hemoglobin)

Development of myelin sheath, neurotransmitters

49
Q

Vitamin B12

A

Production of myelin sheaths

Activation of folate

Deficiency = from lack of intrinsic factor

  • leads to severe neurological problems and pernicious anemia
50
Q

Folate

A

Deficiency leads to neural tube defects (spina bifida), and improper DNA synthesis

51
Q

Potassium

A

Positive intracellular ion that helps conduct muscle and nerve impulses

Defiency = leads to weakness, arrhythmia, excessive sweating, and eating disorders

52
Q

Sodium

A

Positive extracellular ion

Exchange for potassium in nerve cells

53
Q

Calcium

A

Large component of bone

Required for muscle contraction

54
Q

Chromium

A

Aids in insulin binding to the cell to aid in the absorption of glucose and AA

55
Q

Pyridoxine (B6)

A

Synthesis of non-essential AA, neurotransmitters

56
Q

Vitamin C

A

Synthesis of collagen, and connective tissue

Deficiency leads to scurvy

Q

Antioxidants

A

Protect against oxidative damage from free radicals

Vitamins = C, A, E

Mineral = selenium

58
Q

Beta-carotene

A

is a vitamin A provitamin

59
Q

Erythropoiesis

A

The formation of red blood cells

60
Q

Hemoglobin

A

Transports oxygen to the body and delivers it to myoglobin, where it exchanges oxygen for carbon dioxide

61
Q

Macrocytic or Megaloblastic anemia

A

Improper DNA synthesis from a folate deficiency leads to a decreased cell division and enlearged red blood cells called these

62
Q

Deficiency in Iron

A

most common form of anemia

most common nutrient deficiency

most toxic mineral

63
Q

Ferritin

A

Storage protein for Iron

64
Q

Transferrin

A

The transport protein involved in delivering iron to the body

65
Q

Iron needs are increased in this population

A

Premenopausla women because of increased iron lost during mensturation

66
Q

Vitamin K (required)

A

required for blood clotting as it is a coenzyme in the formation of prothrombin

67
Q

Anticoagulants

A

Aid in reducing this clotting mechanism by vitamin K inhibition

ex. warfarin
