The ureters to the urinary bladder,
Both the sheep and the pig kidneys are bean-shaped and both have the main
structures – cortex, medulla and renal pelvis. They were different color; the fetal
pig’s was reddish-brown and the sheep’s was greyish-yellowish ( not sure if it was
because of the chemicals).
b. Describe the location of the kidneys in the fetal pig.
Kidneys are located in the retroperitoneum.
c. Describe the path that urine takes to exit the body, starting in the kidney.
The urine is made in the kidneys through filtration of blood. It then moves
through the ureters to the urinary bladder, where is stored. During urination the
urine passes through the urethra which is connected to the penis and is discarded
outside of the body.
The two endocrine organs in the throat are the thymus gland and the thyroid
gland. The thyroid gland is a dark and solid organ and is located in front of the
trachea. It secretes thyroxin, which is important for the metabolic control and
calcitonin, which lowers calcium levels in the body.
The thymus gland is glandular-looking and is located posteriorly to the larynx and
over the thyroid and it extends to partially cover the anterior portion of the heart.
The thymus plays an important role in the development and maintenance of the
immune system.
b. Describe three endocrine organs that are located in the abdominal or pelvic
cavities.
The three endocrine organs in the abdominal cavity are the pancreas, the adrenal
glands and the male gonads.
The pancreas is located along the bottom of the stomach. It is yellowish-brown in
color with bumpy texture.
The adrenal glands are located on the anterior surface of the kidneys. Hey are
bean shaped and light in color.
My specimen was a male. The testes are located in the scrotal sac in the pelvic
cavity. They are small with smooth surface.
5. Discuss your dissection of the digestive system of the fetal pig by doing the
following:
a. Describe the major digestive organs, including their name, location, relative
size, and physical characteristics (e.g., color, shape, texture).
The digestive tract has 3 main parts: stomach, small and large intestine.
The stomach is located underneath the liver in the left upper quadrant. It is
pouch-like that is tan in color with a smooth surface. The small intestine is a thin,
long tube which lies in a spiral and that way is able to fit in the tight space in the
and is held together by the mesentery. It is shorter than the small intestine, but
larger in diameter.
b. Describe the accessory digestive organs, including their name, location, relative
size, and physical characteristics (e.g., color, shape, texture)
The liver is a large, multi-lobar organ, brownish in color in the right abdominal
cavity over the liver. In its posterior side is embedded the gallbladder – small,
green elongated organ. Under the stomach is the pancreas – it is yellowish-brown
with bumpy, granular texture.Assignment click HERE
