(jasin,1992)

Description :

Lepus migricollis divided into 4parts, the are : head, cervix, truncus and caudal. In the head can

be found rima oris (mouth hole), nores (rose) and organon visus (eyes). In the head there are

also long shape is classified as tetrapods that has four extremity in leg form. It has large ear and

big eyes with nictitans membrane. Mouth is soft and flexible. Around of mouth there are some

long hair (vibrissae)that has function as smelling organ. It also has short tail with anus located

under of the tail. Urogenital hole located in anterior part of anus. It has long and strong legs that

use to jump. Front has five fingers and hind log has four fingers. Body skin is covered almost by

thick hair, covered almost entre part of the body. Vibrissae has function to detect the food

under the ground. In this animals, female, female one has four until five fairs of nippes in the

ventral side of the body.

Description :

1) Digestive system

Concists of digestive tracts and digestive gland. Digestive tracts consists of cavum oris, pharynx,

esophagus, ventriculus, intestrinum and anus. And digestive gland are salivary gland, mucosa

gland, hepar and pancreas. These has unique digest way, they fead cut their food that had been

digested with their feses and then it will eat again for the second time and the important

vitamins will absorp.

2) Circulatory system

Circulation of blood in rabbit’s is classified as closed circulation. Heart is relatively small and

located inside of cavum thoraxica or thest hole. That covered by pericardium that has two

layers. It has distrinctive charactive, it has branches or aorta curve to be arteri innaminator and

left subolavia artery. These artery innaminator will be there bronches, they are night subclavia

artery, night carotis artery and left conatis artery. It different with human, that just had one

vena cava anterior in left side.

3) Respiratory system

In the observation of respiration system there are one pair of nose hole pharynx, larynx and

then lung that yellowish red color that has located near or steleton. Gasus enter through cavum

aris and then go to pharynx, larynx and towards to glottis. After that, it go towards to branched

tractic to be bronchi and it also branches inside of pulmo and there are alveoli bubble that

connected by bronchios. This alveoli surrounded by blood capillaries and in the place the

exchange of o2 and co2 is occus.

4) Excretion system

It consists of kidney that has shape like alidneys. almond shape. Urine is realeased out by two

kidneys. That distributed in ureter and collected in vesina urinaria will automatically pump the

blood out from urethtra. Rabbit urine contain many cartons and it also so condensed becaused

calcium cartonate and it also cong get color excharge to be dork red depended on their foud.

5) Nervous system

The nervous system consists of two parts, they are CNS and PNS. CHS consists of brain and

medulla spinals. In the brain consists of cerebrum and cerebellum. Cerebrum plays important

role as activity coordinator and the PNS has function to called the information in implus from to

distribute to CNS and took impuls from. CNS to the motoric sensory.

6) Reproduction system

Consists of genital interna and externa. In female organisms, interna organ consists of a pair of

ovarium and uterus. Ovarium in caudal side of ren and uterus is rotated caral. Externa organ

consists of vagina, vulva,labium majus,labium minus and clitoris. Testis is a pair and located in

scrotum.

9. Caudal

Description :

Mus musculus divided into 4parts, they are, hrad, cervix, truncus and caudal. In the head can be found

nose hole,mouth, eye and eare. The ears shape is obtwe and rounded. The structure of ears is soft and

smooth. The body is covered by hair that thick and soft with white color. It has long tail that has a little

har and has a line of cycle,. Eye is red and it has doris convinus that long and has shape. Cervix is short

and covered by thick hair. Truncus is round and short with two pairs extremity. A pair hind log that

consists of femus and monus. Hind leg consist of 5 finger with nail tip. The front log is shorter than hind

leg and it use to hold the food. It consiists of arm and moris. Caudal is long and soft with pinkish color. It

is consists of flexilael hissuos.

Anatomy

1. Digestive system

Consists of digestive tract and digestive gland that connected each other. Digestion in the mouth

and mouth hide. Food are crushed by don’t and wet by saliva. Distributed by pharynx and

esophagus. Digestive in stomach and intestinum tenue changed to be amino acid,

monosacharyde and basical dements obsorption in colon and out from the body.

2. Circulatory system

Cor located in front of chest hole in the side. Hearts has four room that perfectly devided and

located inside of chest and covered by pericardia. It consists of two atrium and two ventricles. It

contructed by there kinds of miocardia, it is ventriculus muscle. Atrium musle and stimulator

muscle fiber and special conductor.

3. Respiratory system

Lung is located inside of hole in the left and right side of heart. Right lung consists of three

groups of dueotus and of two lobus. Inside wing, bronchus in right side are three branches and

left bronchus are bronched to be two parts. Function of wings is exchange 02 from the with

cartonm dioxide from the blood.

4. Excretion system

Kidney is located in posterior wall of abdomen behind of perisoneum. Kidney shape like nut

seed. Right kidney is lowes then left kidney, because the prerence of big heparis dextor. Every

kidney covered by thin membrane that called as capsulla fibrosa in cortex renalis.

5. Reproduction system

Male genitalia system has function to produce male gammattes, it is sperma genitalia male

divided into interna genitalia and externa genitalia. Externa genitalia consists of penis and

scrotum and interna genitalia consists of testes. Reproduction tract and reproduction tracts and

reproduction gland female organiem. Genitalia externa consists of vulva, pubis , ditoris and

interna geritalia consists of ovarium, tubarion ducts and vagina.
