Title: LAST LECTURE WE TALKED ABOUT


1
LAST LECTURE WE TALKED ABOUT DIETARY MINERALS IN
SPORTS TODAY WE WILL TALK ABOUT WATER
2
Lecture 15 WATER
3
OUTLINE OF LECTURE 15 WATER-SOME GENERAL
COMMENTS
4
OUTLINE OF LECTURE 15 WATER-IDATME WATER-FUNCTI
ONS WATER-SOURCES -DEFICIENCIES
AND TOXICITIES -WATER BALANCE
-INTERACTION WITH OTHER
NUTRIENTS AND IONS
5
WATER-SOME GENERAL COMMENTS     H2O 
6
WATER- GENERAL COMMENTS CONTINUED Essential-we
can make it but not nearly in sufficient
quantities
7
WATER-IDATME INGESTION- oral, tube,
intravenous DIGESTION not broken
down   ABSORPTION-passive large and small
intestine TRANSPORT-free
8
WATER-IDATME   METABOLISM- already in
correct form
water in water out
-we can make water-Krebs
-synthesis
-we can consume water-catabolism EXCRETION-
sweat, urine, faeces, lungs

FUNCTIONS OF WATER -carries nutrients and
wasteproducts -fluid and electrolyte balance -ion
balance -maintains the structure of large
molecules e.g. proteins and
glycogen -participates in chemical
reactions -serves as solvent for
nutrients -temperature-regulation -blood
volume-regulation
11
-carries nutrients and wasteproducts
 
12
-fluid and electrolyte balance -fluid balance in
cells critical or cells burst -water dissolves
compounds into water creating ions -ions are
charged particles eg Na andCl- -must have equal
number of charges in pool eg Na and Cl-
i.e. that cations must balance the anions in
terms of charge so that the net charge is
zero -or get electrolyte imbalance
 
13
Fig. 12-4, p. 390
14
-fluid and electrolyte imbalance -sweating -diar
rhea -vomiting all cause imbalance- fixed by
food and drink
 
15
Fig. 12-6, p. 391
16
-acid base balance (pH) ion balance regarding
carbon dioxide buffers-bicarbonate and carbonic
acid lungs-carbon dioxide kidneys-bicarbonate

-maintains the structure of large molecules
e.g. proteins and glycogen
20
-participates in chemical reactions
-splitting- catabolism -elimination-anabol
ism -electron transport chain
-elimination and electron transport
chain-metabolic water
21
-participates in chemical reactions -splitting

-serves as solvent for nutrients
25
 
-temperature-regulation
26

-blood volume-regulation
27
WATER BALANCE
water balance required for all this above
28
Table 12-3, p. 385
29
 
  WATER- TO MEET FUNCTIONS AND WATER
BALANCE Sources-foods, drinks, water

Table 12-2, p. 385
31
WATER TOXICITIES AND DEFICIENCIES water balance
is water inwater out i.e.
IDATME note water
in-consumption and
metabolic water we make

water out- urine, faeces, sweat,
lungs, vomiting and diarrhea
water balance required to avoid deficiencies and

toxicities
32
WATER TOXICITIES AND DEFICIENCIES Deficiency-loss
of function Toxicity-metabolic interference
33
WATER TOXICITIES AND DEFICIENCIES Deficiency-loss
of function-elaboration
-electrolyte imbalance
34
Table 12-1, p. 384
35
WATER TOXICITIES AND DEFICIENCIES Toxicity-metab
olic interference -congestive heart
failure -blood pressure
-renal damage-further fluid imbalance
-electrolyte imbalance
-cells bursting
36
WATER TOXICITIES AND DEFICIENCIES Not likely if
one is following an appropriate diet at all
times Proper diet ensures sufficient
water Water and the macronutrients they interact
with frequently come in a package
37
THUS THERE IS AN INTEGRATION OF SOURCE, FUNCTION,
DEFICIENCY AND TOXICITY
38
INTEGRATION OF WATER WITH OTHER NUTRIENTS AND
IONS CARBOHYDRATES LIPIDS PROTEINS VITAMINSMINER
ALS OXYGEN IONS
39
INTEGRATION OF WATER WITH OTHER NUTRIENTS AND
IONS CARBOHYDRATES -shape-function
-interaction with other nutrients in
solution -solvent including water
soluble fibre -idatme -wwfq
