Alt language

vitamins biological activitt varies by form so activity must be expressed in activity equivalnets A,E Niacin, Folate

Vitaman A and D do what?

Act like hormones by binding nuclear receptors

Vitamin E protects

cell membrane

My blood calcium is low

Gland release PTH hormones

• The kidneys increase CA reabsorption

• Bones release Ca 2+ and phosphate '

• In the intestine, calcitrol inc, Ca2+ absorbption

ICF

inside cells 2/3 total body water KKKKKMGMG

ECF

outside cells1/3 total body water NANANA

Dehyfrated

• ADH is released

• water reabsorption back into kidney

• urine volume dec

• urine becomes highly conc.

Blood volume drops

• renin released form juggle cells

• Ang 1 turns into Ang II

• This causes intense vasoconstrcition

• everything is reabsorbed expcprt K
