1. Calcium and
Copper

Period 2

2. Calcium chloride, CaCl2, is a
salt with many uses in our
human body:
The calcium is ingested in our body
thru some foods that are drinkable:
Milk and dairy products such as
yogurt, cheese, and ice cream.
Calcium could be ingested or
eaten, some vegetables like
cabbage, spinach, broccoli,
carrots, cauliflower, eggplant, kale,
parsley, peas, pumpkin, turnip,
dandelion and asparagus are rich
in calcium.

3. Calcium is important in
our diet because…
 It is a structural
component of bones,
teeth, muscles and soft
tissues.
 It helps the human body
to grow during childhood,
adolescence, and
pregnancy.

4. What happen when the body
does not received enough
Calcium?
The body takes calcium from
their own bones causing
bones fractures and
osteoporosis.
Osteoporosis is a condition
in which bones become
weak and brittle, increasing
the chance they may break.

5. What happens when the
body consumes too much
Calcium?
High calcium intake can cause
kidney stones. Kidney stones are
made of calcium.
When humans get in contact with
calcium chlorine in large
amounts, they may suffer severe
irritation or burn of the eyes or
skin, vomiting or nausea.

6. Copper (Cu29) is a metal
that is use largely in our
civilization.
 It use for electrical
equipment due to its
electrical conductivity
properties.
 Copper is used to make
many alloys such as
bronze and brass.
 It can be found in a small
amount in humans,
animals, and plants.

7. Copper is a vital elemental
nutrient that is necessary for
good health .
 Human ingest copper in salads, fruits, poultry, and
meat in small amounts that are not harmful to the
body.
 After copper is ingested, it is absorbed from the
small intestine into the bloodstream. Here copper
transform proteins, which carry it to the liver. Then, it
gets distributed throughout the body.

8. The excess of copper
could be unsafe to
humans.
 People can ingest excess of copper by drinking
water and foods (plants and lakes treated with
cooper). It can also enter the body through the skin.
 Some homes have copper plumbing pipes, there is
a chance that your drinking water may include a
high level of copper.
 Excess amount of copper can causes nausea,
vomiting, diarrhea, liver damage, kidney damage,
and some cases death.
