HUMAN NUTRITION

ARE

substances the body
takes it to sustain the
life of cells...

2 TYPES

INORGANIC

Watter

THESE:

It makes up two thirds of the human body

The chemical reactions that make life
possible occur in watter

Oxygen

Is a gas you obtain from the air, and not from food

Minerals

ARE:

nutrients that humans need in small quantities

involved in the regulation of internal processes
and used as building materials.

ORGANIC

Carbohydrates

ARE:

moleculs composed of carbon,
oxygen, and hydrogen

THESE:

The main source of energy
for cells.

Provide the raw materials from
which cells can from biomoleculs.

Fats

ARE:

moleculs made up of carbon,
oxygen, and hydrogen.
Are a type of lipid

THESE:

Nutrients that contain the
most energy, are stored
in specialized tissues.

Used in the formation of biomoleculs
and are the main component of
cellular membranes.

Proteins

ARE:

moleculs that are mainly up of
carbon, oxygen, hydrogen, and
nitrogen.

THESE:

Is a process the body needs for
growth and repair

Can be used as an energy source if all
the carbohydrates and fats been used
up by the body

Vitamins

ARE:

organic components that the body
either cannot produce or produces
only in insufficient quantities.

THESE:

Are needed in small quantities

Are essencial for regulating many
cellular processes in the body

IS

a liquid made up of two elements

PLASMA

IS

a 55% of the blood composition

a aqueous solution made up of several
solutes. It contains several nutrients

CELLS

a 45% of the blood composition

may be red blood cells, whithe bloods cells
or platelets

RED BLOOD CELLS

Are

Are.. Erythrocytes, make up the largest
volume of blood cells. These cells lack a nucleus
and are specialized in transporting oxygen.

WHITE BLOOD CELLS

Are

Are... smaller in the volume. And there are
different types of leukocytes, all they have
nuclei and are part of the body response.

PLATELETES

Are

cell fragments that participate in the blood clotting
and control the bleeding process.

IS:

the physical and chemical process by
which foods are converted into nutrients
that can be absorbd by cells

we needed to

obtain oxygen from the air and adds
it to the blood; it also releases carbon
dioxid.

we needed to

transports nutrients to all cells in
the body and removes metabolic
waste from the cells.

we needed to

filters waste and extra salt from the blood
These are eliminated in the urine. This system
also regulates the body's water balance.
