Hello teachers and friends. I named A through from Group 1 and our team consists of 8 members is
A BCDEFG H. Today we are here to present to you ề structure of our bodies. I will
turn the presentation with you on the external parts, inside and skeletons
First B will give us information on the external parts of the body.
As you know, parts outside the body is divided into three main parts: head, neck, torso, two arms and
two legs. Outside the body was covered by a layer of skin called.
The head and neck, as on the drawing include parts eyes, ears, nose, mouth, cheeks, forehead, eyebrows, eyelashes,
hair, neck. these parts are an important function and certain of the human body: the eyes
to see, ears to hear, noses to smell, ...
Next to the body, including parts: breasts, navel, belly
finally the two legs and two arms. In arms with elbow parts, hands, fingers, wrists, heart
hands, forearms. In the legs there parts: thighs, knees, legs, feet, toes, ankles,
hips, caves, genitalia
Each external parts of the body are very important functions for the human body,
the inner parts and skeletons to form the body.
that's all that I want to give to you about the external parts of the body. Thank
you for listening to my presentation.
Thank you to the presentation of group B. Next we will present on the inner parts of
the human body.
The inner parts of the body is divided into six organ systems were: urinary system, endocrine system, tract
chemical, circulatory system, nervous system, respiratory system.
first invites you C up to us to present the excretory system.
C : excretory system consists of two kidneys, the urethra and bladder. The kidneys filter the blood agencies substances
from the blood of waste and residues residues. Therefore, excretory system and exhaust filter acts harmful substances
for the body to the environment. In addition, the skin has sweat glands secretion also on duty. The place
is also sweat a manifestation of the excretion.
D: The circulatory system consists of the parts is the heart and blood vessels. The three types of blood vessels are arteries, and veins
and capillary vessels. Tim is a very important part of human beings, it helps sustain human
life. Functional circulatory system transporting oxygen, nutrients and hormones to every cell and
carry the waste out of the body.
E: Respiratory system consists of parts nose, pharynx, larynx, trachea , bronchi and lungs that brings oxygen
into the lungs and the potty dioxide emissions into the environment
F: digestive system including the mouth, esophagus, liver, small intestine, large intestine and digestive glands. Digestive system function
of putting food into the body, transform food into essential nutrients for the body and
the waste products out.
G: The nervous system consists of parts including the brain, bone marrow live and nerves. This system Charge control
the activities of the body, causing the body to adapt to changes in the external environment.
H: internal system to include the pituitary, thyroid, pancreas, kidney and upline gonad. It serves
hormone secreted away under the blood sugar to balance the physiological for the human body.
The main component of the skeleton
The human skeleton is divided into three parts skull (including the facial bones and neurocranium) , skeletal body
(including the sternum, ribs and spine) and limb bones (bones spending on - hand and lower limb bones -
feet). All 300 bones in children and 206 adult bones, long, short, flat other
in each of the joints. In skeleton has many firmware. Neurocranium in humans consists of 8
bone graft creates large skull containing the brain. Small facial bones, jaw bones less crude than animals because
chewing food is not cooked and defensive weaponry. The formation protruding chin involving motor
languages. The spine consists of 33-34 vertebrae fit together and bent at the 4 spot, the letter S after the other two help
the body upright. The ribs attached to the spine and sternum associated with forming the chest, protecting
the heart and lungs. Hand and foot bones bones respective parts together but different segmentation in line
with the functions upright and labor.
The type of bone
Bone Flat: the flat shape, slim as the scapula, iliac wing bone, bones skull. This type of bone at
the most.
The bones do not have (bone formation uncertainty): is the complex bone shaped like maxillary,
xuongthaii positive, in the base of the skull bones. + Create and Lift: The bones linked together to form the frame
and the fulcrum hard to improve the whole body, to help people with upright posture.
The role of the skeleton;
+ Protect: Bone protection inner organs from injury, such as the skull protects the brain,
spine protects the spinal cord.
+ Exercise bones combined with the lever system that created the fulcrum is the joints, ensuring that
activities of the body. Such bones passive role in mobilizing apparatus.
+ Hematopoietic: Bone marrow is where blood created.
+ Metabolism: Bone is where the fat reserves, mineral salts, specialty
