The Angora goat (Capra /iircus) has been tile minII experimental animal ti.,ed by the Biophysics Division ofthe Biomedical Laboratory for many years. Knowledge tst goat anatomy is imipoitant during both the planningand experimental stages of projects. Because no readily usable information on goat anatomy is available, a sariesof reports on the subject is being prepared. The first iii thle series described thle skeletal anatomy; the seconddescribed the cross-section anatomy; the third described tile muscles on superficial and deep dissection of thehead, neck, and pectoral and pelvic limbs. This report concerns the internal organs and describes the structuresof each organ.

A HI AS 01: GOAT ANATOMY
lAR IV: INTFRNAL ORGANS
1. INTRODUCTION.
Thi: Angora goat ((iqpre Wrens) has been the inain experimental animal used hylte Biophysics Division~ ol, tile Biomedical Laboratory For many years. Knowledge ot' goalanatomny is important during both tile planning and experimentaml stages of' projects. Bvccuuiseno readily usable information ()on goalt anatomy is available, a series ol reports on the subject
ais bveing prepared. The first in lte serk-0~ described the skeletal anatomy: lte second2 describediii' cross-sectional anatomy: anid thie third-' described [lie mnuscles onl superficial and deepdissetion of' the head. neck. and pectoral and pelvic Aieis
This report concerns the internal organs and describes the structures of' eachorganl.
11. MATERIALS AND ME-THODS.
Eight castrated Angorai goats were used. Each goat was euthanized withphenobarbital sodium. The toals were of average size, weighing 40 to 50 kg. Deep dissectionwas done on fo.ur goats showing the right and left lateral side with tile internal organs intact(figures I through 4). Another goat -was dissected to show the ventral view of the qbdonlinalviscera (figvie 5) and the ventral view of' the lungs (figures 6 and 7). Three goats weredissected te obtain the internal organs. The organs were either drawn or photographed andlabeled accv-rdingly. The drawings are placed with some of the photographs with a centimeterscale shc'wing the exact size of the organ.
A total of 14 drawings and 28 photogiaphs was made while the dissection of theorgans was taking place. The organs dissected were the 'brain, tongue, !ungs, heart, liver.kidneys, adrenal, spleen, pancreas, and the stomach (figures I through 31).
The drawing of the digestive system in the domestic goat shows the passagewaythrough the system of thi, four stomachs (abomasum, retictlmini. onmasum. and rumnen)(figure 29).
The anatomy books of Sissoni and Grossman" andl Nlwi" anmd the excellent bookby Miller et al.' were, used as references during the preparation om thi, atlas.
