THE HUMAN BODY
The human body consists of three parts. They are the head, the trunk and the limbs. There are many bones of different sizes and shapes in the skeleton. The bones are connected together by the cartilages, the ligaments and joints. The joints allow the bones to move.
The main part of the head is called the skull. The bones of the skull are composed of cranial and facial parts. The skull encloses the brain. The, forehead, the temples, the cheeks, the cheekbones, the two jaws and the mouth compose the face. The teeth and the tongue are lodged in the mouth. One chews food with the teeth and tastes food with the tongue. The lips are the two margins of the mouth. We see with the eyes, breathe and smell with the nose and hear with ears.
The trunk consists of the spine, the chest and the pelvic bones. In the spine there are many vertebrae. They are cervical, thoracic, lumbar, sacral vertebrae and the coccyx. The trunk is divided into two large cavities by diaphragm. The upper cavity of the trunk is called thorax and the lower one is called the belly. In the middle of the thorax (the chest) there is a long bone the breastbone by name. The ribs are connected with the breastbone by cartilages. The lungs and the heart are located above the diaphragm the upper cavity. In the lower cavity (abdominal cavity) we find interior organs such as stomach, liver, urinary bladder, gallbladder, kidneys, spleen and intestines (bowels). There are two nipples on the chest, and, in women, the breasts with the teats. There is the na¬val in the middle of the abdomen. At the lowest part of the abdomen there are genitals (the external reproductive organs).
The upper limb (extremity) is divided into the shoulder, the upper arm, the forearm and the hand. The joint between upper arm and forearm we call the elbow. The wrist is the joint between forearm and hand. Each hand has five fingers: index (fore-finger), middle finger, ring finger, little finger and a thumb.
The lower limb consists of the thigh-bone (the femur), the shin-bone (the tibia) and the fibula. We call the calf the back of the lower leg. The joint between the femur and the lower leg is called the knee-joint. This joint is protected by the knee-cap (the patella). The joints between lower legs and feet are the ankles. The foot consists of heel, sole and toes.
The muscles form about 40 per cent of the body weight. They are subdivided into three groups. These groups are the musiles of the trunk, head and extremities. There are about 600 skeletal muscles. As far as their form is concerned they can be long, wide and short. The long muscles compose the free extremities, the wide ones lay on the trunk and from the walls of the body cavities. The short muscles are not numero¬us. Some of them form facial muscles. Muscles are attached to bones, internal organs and blood vessels. They allow us to make an internal or external movement due to their contraction and relaxation.
As for the structure of the muscles there are also three types of them: striated (skeletal) muscles, smooth (visceral) muscles and a cardiac muscle. The first ones move all the bones, face and eyes. The second ones move our internal organs such as the digestive tract, blood vessels and secretory ducts. We have no conscious control over visceral muscles and a cardiac muscle. The muscles contain many muscle fibers (cells) which are connected together by connective tissue. It goes without saying that there are many nerves and blood vessels in the muscles.

INSON tana
The inson tanasi uch qismdan iborat. Ular bosh, magistral va oyoq bor. Skelet turli registri va shakllar ko'p suyaklari mavjud. suyaklar tog'aylarida, bog'lamalari va bo'g'imlarning tomonidan birgalikda ulangan. bo'g'imlarga ko'chib suyaklari. imkonini beradi
rahbarining asosiy qismi Boshsuyagi deyiladi. Boshsuyagi suyaklari Boshsuyagi va yuz qismlari topgan. Boshsuyagi miya o'z ichiga oladi. , Peshona, ibodatxonalar, yonoqlarini, cheekbones, ikki jag'ning va og'iz yuzini tashkil etadi. tish va tili og'ziga misafirizdir. One tishlari bilan oziq-ovqat paymol, kishilar ko'ziga va til bilan oziq-ovqat ta'mi. lablari og'zidan ikki hoshiya bor. Biz ko'zlari bilan, nafas va burun bilan hid va quloqlari bilan eshitib qarang.
magistral umurtqa, ko'krak va tos suyaklari iborat. Umurtqa pog'onasi juda ko'p vertebra bor. Ular, ko'krak, bel, sakral vertebra va dumg'aza bachadon bor. magistral Diafragma tomonidan ikki katta BIV bo'linadi. tanasiga yuqori chuqur ko'krak qafasi, deyiladi va pastki bir belly deyiladi. Ko'krak o'rtasida (ko'krak) uzoq suyak nomi bilan ko'krak suyagi bor. qovurg'a tog'aylarida tomonidan ko'krak bilan bog'liq. o'pka va yurak diafragma yuqori chuqur yuqorida joylashgan. Pastki bo'shlig'ida (qorin bo'shlig'i), biz bunday oshqozon, jigar, siydik pufagi, o't pufagi, buyrak, taloq va ichak (ichak) kabi ichki organlarni topish. Ayollarda ikki ko'ksiga ko'krak, va, satrlari bilan ko'krak bor. Qorin o'rtasida na¬val bor. Qorin eng kam qismida jinsiy a'zolar (tashqi jinsiy organlar). Bor
yuqori terminatori (uch) elka, yuqori qo'li, bilak va qo'l bo'linadi. yuqori qo'l va bilak o'rtasida qo'shma biz tirsak qo'ng'iroq. bilagini bilak va qo'l o'rtasida qo'shma hisoblanadi. Har bir qo'l besh barmoqlari bor. Indeksi (old-barmoq), o'rta barmoq, ring barmoq, kichik barmoq va bir thumb
past oyoq boldir suyagi (son), Shin-suyak (tibia) va kichik boldir suyagi iborat . Biz buzoq past oyoq orqa chaqiradi. femur va pastki oyog'i o'rtasida qo'shma tizza bo'g'imi, deyiladi. Bu qo'shma tizza ko'zi (patella) bilan himoyalangan. pastki oyoqlari va oyoq o'rtasida bo'g'imlarga to'piqlari bor. oyoq tovoni, yagona va oyoq barmoqlari iborat.
mushaklari tana og'irligi 40 foiz atrofida tashkil etadi. Ular uch guruhga bo'linadi. Ushbu guruhlar magistral, bosh va oyoqlarning musiles bor. 600 skelet mushaklari bor. O'qisak, ularning shakli bilan bog'liq bo'lib, ular uzun, keng va qisqa bo'lishi mumkin. uzoq mushaklari bepul ekstremiteleri tashkil, keng bo'lganlar tanasi va tanasi bo'shliqlar devorlaridan yotardi. qisqa mushaklar numero¬us emas. Ulardan ba'zilari yuz muskullar hosil qiladi. Mushaklari suyaklari, ichki organlar va qon tomirlari yopishtiriladi. Ular bizga tufayli qisqarishi va dam olish uchun ichki yoki tashqi harakatini qilish imkonini beradi.
muskullar tuzilishi kelsak, ular uch turdagi ham bor: ko'ndalang-targ'il (skelet) mushaklari, silliq (vistseral) mushaklari va yurak mushak. birinchi bo'lganlar hamma suyaklari, yuzini va ko'zini harakat. ikkinchi bo'lganlar bunday ovqat hazm qilish trakti, qon tomirlari va sekretor kanallarida bizning ichki organlar harakat. Biz vistseral mushaklar va yurak mushak ustida hech qanday ongli nazorat ega. mushaklari biriktiruvchi to'qima bilan birga ulangan ko'p mushak tolalar (hujayralar) o'z ichiga oladi. Bu mushaklar ko'p asab va qon tomirlari bor deb turib ketadi.
