Tissue Fluid

found between the cells within tissues and organs of the body

Plasma

Tissue type

lean tissues, muscles, organs, bones

Water

excellent solvent and can dissolve many different substance s

Dissolved Materials

solutes that include ions, carbs, amino acids, vitamins, minerals

Blood Volume

amount of fluid in the blood

Why does our temperature of our body fluids remain stable?

fluid helps maintain body temperature because water has a high heat capacity

electrolytes intacellular fluid is

K + potassium

Extracellular Fluid Electrolytes

Na postive sodium

Osmosis

movement of water from one are to another due to a concentration gradient

Thist Mechanism

occurs from a cluster of nerve cells in the hypothalamus that stimulates our desire to drink

metabolic water

contributes about 10-14% of the water the body needs

Fluid Balanced Controlled Hormones

ADH - Antidiuretic Hormone

Sensible Water Loss

occurs through urine and sweat

Insensible Water loss

Occurs through evaporation from the skin or exhalation from the lungs, as well as through feces

Diuretics

Increases fluid loss via the urine and thus anti - diuretics decrease fluid loss

Hypernatremia

abnormally high blood sodium concentration

Hyponatremia

an abnormally low blood sodium level

HypERkalemia

high blood potassium

HypOkalemia

low blood potassium

Dehydration

occurs when fluid excretion exceeds fluid intake

Heat illness

heat cramps, heat Exhaustion, heat stroke

Drink

defined as the amount of a beverage the provided ½ fluid ounce of pure alcohol

Proof

is a measuremnt of alcohol content, which is double the percentage

Alcohol Abuse

excessive intake of alcohol

Binge Drinking

is the consumption of five or more drinks per occasion

hangover

is a consequence of drinking too much
alcohol; severe dehydration due to blocking of ADH –
antidiuretic hormone

Alcohol poisoning

is a potentially fatal metabolic state
involving cardiac or respiratory failure

Fatty Liver

is an early but reversible sign of liver damage if drinking is stopped

Alcohol Hepatitis

Result in loss of appetite, nausea and vomiting, abdominal pain and jaundice

Cirrhosis of the liver

involves permaent scarring after years of alcohol abuse

Fetal alcohol syndrome (FAS)

a set of
serious, irreversible birth defects, including
physical, emotional, behavioral, and
developmental problems

Fetal alcohol effects (FAE)

subtler
consequences that may be exhibited later,
including hyperactivity, attention deficit
disorder, and impaired learning abilities
