LAB 14 More Abdominal Viscera
- Expose and palpate the abdominal viscera through paralumbar incisions in the abdominal wall.
- Through an incision in the caudal part of the dorsal ruminal sac on the left side, remove most of the ingesta and then palpate internal structures.
- Enlarge the right paralumbar incision and observe the layers of the omentum.
What is the function of the pericardium?
The pericardium is divided into three membrane layers:
- Fibrous pericardium is the outer fibrous sac that covers the heart. ...
- Parietal pericardium is the layer between the fibrous pericardium and visceral pericardium. ...
- Visceral pericardium is both the inner layer of the pericardium and the outer layer of the heart wall. ...
What is the function of visceral pericardium?
Visceral pericardium is both the inner layer of the pericardium and the outer layer of the heart wall. Also known as the epicardium, this layer protects the inner heart layers and also assists in the production of pericardial fluid.
What is the function of the fibrous pericardium?
What is the Pericardium?
- Structure. Pericarditis can cause pain and shortness of breath. ...
- Functions. Individuals who have experienced a recent heart attack or sustained trauma to the chest and heart may develop pericarditis.
- Pericardial Disorders. Excess fluid between the heart and the pericardium is referred to as pericardial effusion. ...
What is the function of the pericardium in a pig?
Pericardium, the covering of the heart, lining the pericardial cavity which is the sac containing the heart, bathing it in fluid and keeping it separate from the expanding lungs during breathing.
What is the pericardium in a fetal pig?
The pericardium is a membrane that surrounds the heart and lines the pericardial cavity. It contains a lubricating fluid and isolates the heart from body movements such as the expansion and contraction of the nearby pleural (lung) cavity.
Where is the pericardium in a pig?
the heartThis visceral pericardium is the thin, shiny membrane on the surface of the heart.
What are the four parts of the heart in a pig?
Like human hearts, pig hearts consist of four chambers (two atriums and two ventricles). They also have four valves and an aorta, just like humans. During the 30-minute dissection, students are able to identify the different parts of the heart and trace the path of blood flow.
Where is the pericardial sac?
heartYour heart is surrounded by a double-layered membrane, called the pericardium or pericardial sac. This membrane keeps your heart in place in your chest cavity, restricts the expansion of your heart when your blood volume increases, and helps to protect your heart.
How many hearts does a pig have?
The heart is located in the thoracic cavity nestled between the lungs on the body's midline. Pigs like other mammals have a four-chambered heart. The right side of the heart pumps blood to the lungs (pulmonary circulation), and the left side pumps blood out to the rest of the body (systemic circulation).
Are pigs hearts the same as humans?
Pig hearts are anatomically and functionally similar to human hearts but, obviously not identical. These differences can cause organ rejection. This happens when the body's immune system treats a new organ as an unwelcome a foreign object and attacks it.
How do pig hearts look?

What are the differences between a pig's heart and a human heart?
An important difference is the presence of the left azygous vein in pigs, which drains directly into the coronary sinus; the human heart lacks this anatomic arrangement. In the swine heart, the right auricle has a narrow tubular appearance, compared with the triangular shape of that in humans.
Why are pigs hearts chosen?
This means the human heart has to pump hard to push blood vertically, whereas the pig heart has an easier time pumping horizontally. Whether the pig heart can generate (or withstand) the pressures needed in humans is unknown.
What animals have 4 chambered hearts?
Bird and mammal hearts have four chambers (two atria and two ventricles).
Which chambers are the receiving chambers of the pig heart?
The right atrium is one of the receiving chambers of the heart. It is thin walled, small in comparison to a ventricle and resembles the shape of an ear. Blood flows into the right atrium from the vena cava.
What is the purpose of bovine pericardium?
Principally composed of collagen, pericardium provides strength and elasticity. Bovine pericardium is used extensively in applications including bio-prosthetic heart valves, dural closure, bone and dental membranes, ...
What is bovine pericardium used for?
Bovine pericardium is used extensively in applications including bio-prosthetic heart valves, dural closure, bone and dental membranes, and surgical buttressing. Collagen Solutions offers a variety of tissue harvesting and selection options to meet manufacturer’s requirements.
What are the benefits of pericardium leaflets?
Pericardium has the mechanical properties needed to achieve the best hemodynamics so patients do not have to undergo long-term blood thinner therapy . Neonatal bovine pericardium may have additional benefits for use as leaflets in percutaneous bioprosthetic heart valves because it is thinner and more elastic than the adult form. Collagen Solutions has been granted a patent for the preparation and use of neonatal pericardium for several applications.
What is the term for the loss of support of the anterior or posterior vaginal wall?
Pelvic organ prolapse refers to loss of support of the anterior or posterior vaginal wall or the vaginal apex leading to protrusion into or out the vaginal canal of the bladder, rectum, small bowel, and uterus. Surgeons have recently begun to explore the use of decellularized ECM, such as pericardium, to replace weak tissues that permit prolapse.
Is the neonatal pericardium a leaflet?
Neonatal bovine pericardium may have additional benefits for use as leaflets in percutaneous bioprosthetic heart valves because it is thinner and more elastic than the adult form. Collagen Solutions has been granted a patent for the preparation and use of neonatal pericardium for several applications.
What is the purpose of pericardium?
Pericardium, of both bovine and porcine origin, has become widely used in cardiovascular surgery over the last two decades. One particularly common use is as a patch for arteriotomy closure ( Fig. 3.3), and bovine pericardium is predominant in the United States. Compared with synthetic patches, bovine pericardium has superior biocompatibility, demonstrates minimal suture line bleeding, and patency can be immediately confirmed by intraoperative or postoperative ultrasound. 51 Additional proposed benefits of bovine pericardium for use in patch angioplasty include lack of calcification, support of cellular ingrowth, and reduced rates of restenosis and infection. 52–57 Similar to other prosthetic patches, pericardial patches are durable, strong, and available off-the-shelf in convenient sizes. They are easily handled and reliable in consistency.
Why is the bladder lined with pericardium?
The purpose of this change was to improve biocompatibility, thereby reducing the need for anticoagulants.
