Thyroid gland The thyroid gland is prresent around the trachea, nearer to the larynx. Left and right thyroid glands are joined ventrally in pigs.

1. 1) Why does a fetal pig have anything in its intestine?
2) Are there any differences between the thyroid gland, thymus gland, and spleen in a male and
female pig? Breifly explain.
3) Do all members of the animal kingdom have a coelom? What is a coelom?
4) Is there a cause to the color of a fetal pigs intestines? Explain.
Solution
1). Fetal pig is used to study anatomy and physiology because it seems like similar to the
mamalian. gastrointestinal system of the fetal pig contain simliar structure as like mamalian. it
containing osephagous, stomuch, large intenstine.mesentries serve to connect the oragn. it gains
much needed nutrition from the mother by ambelical codes. other organ developing during fetal
development such as pancreas, gall blader, spleen are contributing in digestive system because it
eill produce digestive enzymes. so after digestion the solid waste remain inside in intenstine
though it will exerted which will sent back to the mother by embelical codes.
2.
Thyroid gland
The thyroid gland is prresent around the trachea, nearer to the larynx. Left and right thyroid
glands are joined ventrally in pigs. The thyroid glands receive an abundant supply of blood from
which they are able to uptake iodine. Iodine is used for the synthesis of hormones which contain
three or four iodine moles or atom, triiodothyronine(T3) and thyroxine. Thyroid hormones
regulate metabolism and heat genaration in the body. few cells in the thyroid also produce the
calcitonin (Hormones)
Thymus gland
The thymus is a big gland, is located fronter to the heart and lateral extensions into the neck. The
thymus gland is made of lymphoidal tissue and has a important immunological function in
animals. The animal's immune system with which it protect itself against inactivating
microorganisms. there is significant difference between male and female thymus gland.
male thymus gland shows the secondary lobulation while female thymus glands shows the
simple lobules.
interlabulor septue were thin andshows less vascular in male pig as comare to them female pig
showed thick and highly vascular property.
medulla of the lobules shoews the hassels corpuscles in male pig. medulla shows isolated island
in the lobules in female pig.
medulla occpy larger area in male pif as compare to female pig.

2. no difference is shown in spleen of male pif and female pig.
3.Most of the animal kingdome has coelom. coelom mens hollow cavity, infect it the main cavity
shown in most animal and it is present inside in the body to surround and it contain digestive
part. it lines with mesodermal epithelium.
4.The colour of intenstine is slightly puple. it is due to the presence of mesnteries. mesenteries
are couple of transperant sheets with the petrineoum that suspended and support mechanical
strength to the visceral part of organ.purplish colour of the mesnteries is due to the
vascularization which include both veins and artery.
