THE BODY FACTS.
BY: CHARLOTTE M
THE DIGESTIVE
SYSTEM FACTS
•
The digestive system is responsible for the breaking down of
food that we eat into smaller compartments so that nutrients
can easily be absorbed by the body and the waste
discarded
•
There are two types of digestion. Mechanical digestion is the
physical breakdown of large pieces of food into smaller
pieces through, chewing (mastication). While chemical
digestion uses enzymes to break down this food mass further
into small molecules which the body can separate and use.
•
Saliva in our mouths plays a key role in initial digestion by
moistening the food to help with the mechanical chewing and
swallowing process. Saliva also contains an enzyme which
starts the chemical digestion of starchy foods.
THE HEART FACTS!!!!!
• The heart, blood and blood vessels together make up the circulatory system. The heart pumps the blood through the
blood vessels to all the different tissues of the body. This blood carries water, oxygen and nutrients. Blood is also
important for removing waste products from the body. The heart is essential for your survival! Your heart is constantly
working, even when you are resting.
• The heart is located in-between your right and left lungs in the middle of your chest slightly towards your left .
THE BRAIN!!!
• The human brain is like a powerful computer that stores our memory and controls
how we as humans think and react. It has evolved over time and features some
incredibly intricate parts that scientists still struggle to understand.
• The brain is the centre of the human nervous system, controlling our thoughts,
movements, memories and decisions. The brain contains billions of nerve cells that
send and receive information around the body.
BONES AND MUSCLES
HOW MANY BONES
ARE IN YOUR BODY
There are 270 bones in your body when you
are first born but when you are older you
have 206. You have less bones when you are
older because some bones fuse together.
Human bones grow continually from birth
till our mid 20's. Our skeleton's bone
mass is at its maximum density around
the age of 30.
MUSCLES.
Your muscles are soft tissues in the body of a
human or animal. Its main purpose is to produce
force and movement. Muscles are responsible
for maintaining posture, physical movement
(sitting, walking, eating, etc.), and movement
of internal organs (such as keeping the heart
pumping to circulate blood and moving food
through the digestive system).
FACTS ABOUT
BLOOD CELLS.
The heart pumps blood to your lungs to pick
up oxygen. The oxygen-rich blood is then
pumped out to your body through your
arteries. It's bright red at this point. From
your arteries, the blood flows through tiny
blood vessels called capillaries, where it
gives up its oxygen to the body's tissues.
STOMACH ACID
AND THE
STOMACH.
Stomach acid can also be known as gastric
juice and gastric acid. It is a digestive fluid
formed in the stomach and is composed of
hydrochloric acid.
Stomach acid is not something most people
think about. Yet it’s one of the most
important aspects of your digestive
system!
The stomach is a muscular organ located on the left side of the
upper abdomen. The stomach receives food from the
oesophagus. ... The stomach secretes acid and enzymes that
digest food. Ridges of muscle tissue called rogue line the
stomach. The stomach muscles contract periodically, churning
food to enhance digestion.
