A 6 month old fetus reacts by moving to the
sound of his mother talking or jumps at the
sudden sound of concert drums
A newborn baby has about one cup of blood
A baby can recognize the smell and voice of
its mother at birth.
A baby’s first social smile appears
between four and six weeks after birth
The heart begins beating at four weeks after
conception and does not stop until death.
The fetal heart rate is approximately twice as
fast as an adult’s, at about 150 beats per minute.
By the time a fetus is 12 weeks old, its heart
pumps an amazing 60 pints of blood a day
Because the heart has its own electrical impulse,
it can continue to beat even when separated from
the body, as long as it has an adequate supply of
The heart pumps blood to almost all of the body’s
The lungs contain approximately 2,400
kilometers of airways.
We take approximately 22,000 breaths
every 24 hours
Each lung weigh approximately 1.1
kilogram and entire organ about 2.3
Our lungs are only organs that can
float on water
ABOUT LIVER(HUMAN LIVER IS A
STOCKPILE OF IRON)
In addition to protecting us from any
harmful substances that we may eat or
otherwise put into our bodies, the liver also
cleans our blood from the harmful chemicals
that our own body produces just through
Bilirubin, a chemical that our bodies make
and our liver makes safe, is also filtered by
our kidneys, which is what gives our urine
the yellow color.
Blood makes up around 7% of the weight of a
There are 60,000 miles of blood vessels in the
More than 41,000 blood donations are needed
By comparison, the circumference of the Earth
is about 25,000 miles (40,000 km). That means a
person's blood vessels could wrap around the
planet approximately 2.5 times.
