Question

Explain how mucles and organs get energy

Answer 1

Parts of the body (muscles, brain, heart, and liver) need energy to work. This energy comes from the food we eat.Once in the bloodstream, glucose can be used immediately for energy or stored in our bodies, to be used later. However, our bodies need insulin in order to use or store glucose for energy.

Answer 2

All parts of the body (muscles, brain, heart,
and liver) need energy to work.
This energy comes from the food we eat.
Our bodies digest the food we eat by mixing
it with fluids (acids and
enzymes) in the stomach. When the stomach
digests food, the carbohydrate (sugars
and starches) in the food breaks down into
another type of sugar, called
glucose.
The stomach and small intestines absorb the
glucose and then release it into
the bloodstream. Once in the bloodstream,
glucose can be used immediately for
energy or stored in our bodies, to be used
later.
However, our bodies need insulin in order to
use or store glucose for energy.
Without insulin, glucose stays in the
bloodstream, keeping blood sugar levels
high.
