What is the function of the mesentery in a fetal pig?
The organs are connected to each other and to the inner body wall by thin sheets of connective tissue called mesenteries, which suspend the organs and provide bridges for blood vessels, nerves, and ducts.
What is the function of the sublingual gland in a fetal pig?
The gland is responsible for secreting saliva through the parotid duct into the mouth, which aids in swallowing of food and the beginning of the digestion of starches (you should remember this from lecture). Note: humans also have two parotid glands (one on each side) that are located slightly inferior to the ears.
What is the function of the umbilical cord?
The cord is sometimes called the baby’s “supply line” because it carries the baby’s blood back and forth, between the baby and the placenta. It delivers nutrients and oxygen to the baby and removes the baby’s waste products. The umbilical cord begins to form at 5weeks after conception.
What is the function of the peritoneum?
The peritoneum serves to support the organs of the abdomen and acts as a conduit for the passage of nerves, blood vessels, and lymphatics. Although the peritoneum is thin, it is made of 2 layers with a potential space between them.
What is the function of epiglottis in a fetal pig?
When food is swallowed, the epiglottis folds over the entrance to the trachea to prevent food and drink from entering the windpipe. At rest, the epiglottis sits upright, thus uncovering the opening to the trachea and allowing air to pass into the lungs.
What is mesentery and its function?
The mesentery attaches your intestines to the wall of your abdomen. This keeps your intestines in place, preventing it from collapsing down into your pelvic area. If the mesentery doesn’t properly form during fetal development, the intestines can collapse or twist, per 2017 research.
Which are functions of mesenteries?
The mesentery attaches the intestines to the abdominal wall, and also helps storing the fat and allows the blood and lymph vessels, as well as the nerves, to supply the intestines.
What is the function of the sublingual gland?
It is the only unencapsulated major salivary gland. Sublingual tissue primarily produces a thick mucinous fluid and lubricates the oral cavity which allows for swallowing, initiating digestion, buffering pH, and dental hygiene [3].
What is the upper trunk of a fetal pig called?
The pig’s trunk is divided into two regions: thorax (chest) and abdomen (stomach). Examine the umbilical cord. Observe that it contains three blood vessels: a large vein (blue) and two smaller arteries (red).
What is the ventral of a pig?
belly side
Ventral is the belly side. It is opposite the dorsal side. The pig in figure 1 below has its ventral side up.
What is the difference between the peritoneum and the peritoneal?
Between its two layers – parietal and visceral – is the peritoneal cavity….Peritoneum and peritoneal cavity.
Definition | Serous membrane lining viscera and abdominal cavity wall |
---|---|
Peritoneal divisions | Lesser sac (omental bursa) Greater sac (supracolic and infracolic compartments) |
Why is peritoneum open in females?
Anatomical Parts In the female the peritoneum is not a closed sac, since the free ends of the uterine tubes open directly into the peritoneal cavity.
What is the function of glottis?
The glottis, a slit-like opening on the floor of the pharynx, is a valve that controls airflow in and out of the respiratory passages. The glottis opens directly into a boxlike larynx. This voice box occurs in all amphibians but is anatomically most complex in frogs.
What is the glottis and epiglottis?
Glottis is the narrowest part of the larynx and opens into the airway. Vocal cords make lateral borders of it. Epiglottis, a leaf-shaped cartilaginous flap, prevents the food to enter the airway passage of the respiratory system while swallowing.
Which of the following is a function of Mesenteries?
Which of the following is a function of mesenteries? Mesenteries stabilize the organs of the abdominal cavity.
