SPLANCHNOLOGY
• Science which study viscera of animals.• The root” sphlancnon” means internal organ (the
entrails).• Viscera includes only the organs belonging to
the systems that maintain the life of the individual and secure the continuity of the species, example:
• digestive, respiratory and urogenital System.
![Page 3: Rudy Soekamto Setiabudi Edited by Hana eliyani](https://reader036.vdocuments.mx/reader036/viewer/2022062323/56815966550346895dc6a496/html5/thumbnails/3.jpg)
Structure in general
• Structure organs with or without a cavity, always surrounded by and, if hollow lined by special layers. Whether hollow or solid, most viscera are prominent in the cavity of the body.
• Viscera lined by layers : serous (outer wall) muscular (middle wall) mucous (inner layer).
![Page 4: Rudy Soekamto Setiabudi Edited by Hana eliyani](https://reader036.vdocuments.mx/reader036/viewer/2022062323/56815966550346895dc6a496/html5/thumbnails/4.jpg)
SPLANCHNOLOGY
• Apparatus digestive deals with food.
• Apparatus respiratory with gases.
• Apparatus urinary removes the residues, as do the other two systems also to maintain the metabolic balance and, consequently, that of life itself.
• Apparatus genitalia for perpetuate the species.

BODY CAVITY
• Mamalia have two cavities:
thorax cavity and abdominal cavity separated by diaphragm.
• thorax & abdominal organs were protected by membrane (pleura, pericardia and peritoneum,) this layers produces mucous liquid in the cavity for protecting the adhesion and friction.
![Page 6: Rudy Soekamto Setiabudi Edited by Hana eliyani](https://reader036.vdocuments.mx/reader036/viewer/2022062323/56815966550346895dc6a496/html5/thumbnails/6.jpg)
system digestive = apparatus digestorius =systema digestorium
• Composes of organs which receive & digest the food.
• This tube run along the body, starts from lips until anus
• example : mouth, pharynx, esophagus gaster, intestine & accessory organs: teeth, tongue, salivary glands, liver and pancreas.

TRACTUS RESPIRATORIUS
Respiration organ function in the Organism for :• Breath (respiration); as osmotic and chemical

TRACHEA
compose of Cartilage membranous connecting larynx with Pulmo courses in cervical (pars cervicalis) and enters thorax cavity (pars thoracalis) in the mediastinum space.
• Trachea make bifurcation on dorsal COR at the level V.T 5, this branch term as :bronchus dexter et sinister.
• length : cattle = 65 cm
horse = 70 -80 cm.
goat/sheep = 25 cm
.

Trachea
• Pars cervicalis:
course at the ventral esophagus, a little bit right position.
• Young animal thymus can be found in the ventro-lateral trachea.
• Trachea no 1-4: position of thyroid glands

Cavum thorax
• Apertura thoracalis caudalis: composes of diaphragm fixing tho the costal cartilage no 8, 9 and 10 costal.
• Thorax cavity line by pleural sacs which invaginate from dorsal fold down makes cavum pleura dexter et sinister, which covers lungs.
• Septum longitudinal mediastinum, is a longitudinal space between pleura dexter et sinister

LUNG (PULMO)
• Compose of dexter et sinister, fill the large part of thorax cavity.
• Covers by pleura and fixing by ligamentum pulmonaris• Pulmo of horse compose of sveral lobulus in sinister
part: apicalis & diafragmatica (caudal).• Pulmo dexter: apicalis (=cranialis), diafragmatica &
accessorius• Pulmo dexter et sin same big, only the dexter part more
thicker because it has lobus accessorius (intermediate).

pulmo
• Divides into: basis (facies diafragmatica) and apex (cranial).
• 2 surfaces:(facies costale with impressio costale & medial with impressio cardiaca)
• 3 margo : dorsale, ventrale, basale.• Hilus : location enters/out blood vessels
(A/V), Lymphonodulus and Nerves in the lungs.

BRONCHUS TRACHEALIS
• Develops only in the cattle, goat & sheep.
• The branch from trachea at the right position at the level costae III
• cattle: ± 10 cm before bifurcation
• Goat/sheep : ± 5 cm
• Enters the right lobus apical.

Vascularisation & innervation
• Branches of the artery pulmonary carry venous blood to the lungs. They accompany the bronchi.
• The pulmonary veins (vv pulmonalis) return most of the blood from the lungs and the pulmonary pleura to the left atrium of the heart.
• The nerve supply to the lungs and pulmonary pleura are nn. pulmonalis branch of the n. vagus and nervi symphaticus. Passes through the hilus & supply branches of aa bronchialis and bronchial tree wall.
