o Larynx better known as
the voice box.
o The larynx also protects
the trachea against food aspiration.
o Any disruption in these organs can cause pain
in the throat, loss of voice,
or trouble breathing.
7.
Esophagus
Stucture :
o The esophagus is part
of the digestive system and is commonly
known as the throat.
o This organ consists of a muscular tube through which food passes from the pharynx
to the stomach and through the process of peristalsis.
o Average length of the
esophagus is about 25-30 cm.
Function :
o The main function of the esophagus is to assist in transporting
food to the stomach
8.
Heart
Structure :
o The
heart is responsible for pumping the blood in our bodies.
o The
heart is made of cardiac muscle involuntary, and this is why the heart
continues to beat even when we sleep.
o It
weighs 250-350 grams and is almost the size of a fist.
o The
heart is located on the left side of the chest and is protected by the ribs. The
pericardium is a double-walled sac that encloses the heart, not only protects
the heart but anchor the surrounding structures and prevent the heart from
overfilling with blood.
Function :
o The
main functions of the heart is to provide oxygenated blood to all organs of the
body through blood vessels.
9.
Lungs
Stucture :
o They work very closely
with the heart, and
give an air of pure oxygen to the blood
that is circulated by the heart to the
various organs of the body.
o The lungs also get
rid of carbon dioxide and other impurities from
the blood veins.
Function :
o The heart is almost enclosed by the lung,
so they also
act as shock
absorbers for the heart.
o The lungs also maintain
the pH level of the
blood.
o Lung assist in breathing and is
the most important organ of the
respiratory system.
10. Diaphragm
Structure:
o The diaphragm is the muscular partition between
the chest and abdominal
cavity and extends
at the bottom of the rib cage.
Function :
o The main function of the diaphragm is to assist in respiration.
When contracted, there
is an increase in the volume of
the chest cavity and
air is drawn into the lungs.
o Any interference with the diaphragm
causes problems in breathing.
11. Stomach
Stucture :
o Stomach
is a pear-shaped organ located in the abdomen between the esophagus and
intestines. Depending on the position of the body and the amount of food in the
stomach can change size and shape.
o Stomach
is a large organ and multi-chamber, which houses a special bacteria that
produce enzymes needed for digestion. Removing stomach stomach acid,
hydrochloric acid, and maintain pH levels, which helps in the smooth digestion
of food eaten.
Function :
o Stomach
is a key player in the digestive system
12. Liver
Structure :
o Liver is located on the
right side of the abdominal cavity.
Function :
o Some of the important functions of the liver include
filtering harmful substances from the blood
o Keeping cholesterol and glucose
levels in the blood,
o Secreting specific amino acids
o Storing vitamins and
minerals
o Secrete chemicals that
break down fat
o And converts glucose into glycogen.
13. Pancreas
Structure :
o The pancreas is located deep in the abdomen and
is sandwiched between the spine and
abdomen.
o The pancreas is made up of a number of cells
called the islets of Langerhans.
Function :
o The pancreas is an integral part of the digestive system
o The functions of the head of the pancreas is to
secrete fluid pancreas and insulin, a hormone that affects blood
sugar levels.
14. Small Intestine
Stucture :
o The length of the small intestine in adults is
approximately 22 meters.
o It is primarily responsible for digestion.
Function :
o Small intestine connects
the stomach and the large intestine. The small intestine absorbs nutrients and
minerals in the food
and digested food passes into the large
intestine.
15. Colon
Structure
:
o The
colon is the part of the posterior intestine and length of approximately 5
meters.
o It
is divided into four parts: cecum, colon, rectum and anus.
Function
:
o The
main function of the colon is to absorb water and electrolytes from the rest of
the digestive and keep dirt until excreted.
16. Kidneys
Structure :
o The kidneys are two
bean-shaped organs that filter blood in
the human body. They are also
responsible for removing waste and regulate
electrolyte balance.
Function :
o The kidneys excrete urine into the ureter,
which passed out of the body.
o Another important function
of the kidneys is
to control the body's
fluid balance
o Helps in the reabsorption
of water, glucose and amino acids.
17. Skin
Structure
:
o
In
the skin there are receptors that are sensitive to physical stimuli
(mekanoreseptor). Examples of touch, pressure, recom- cold, and pain. Reviews
These receptors form free nerve endings and nerve endings tissue capsule that
enveloped belt.
o
Generally
each type of receptor can only accept one stimuli only.
o
The
skin serves as a protective device in the part, such as muscles and bones
o
As
an instrument equipped with a variety of touch-sensitive receptors to various
stimuli
o
As
a means of excretion; as well as regulating body temperature.
Function
:
o
The
skin is our sense organs capable of receiving stimuli temperature temperature,
touch, pain, pressure, texture, and so forth
