The Ectoderm
The three embryonic tissue layers of animals are ectoderm, mesoderm, and endoderm. These layers give rise to different specialized tissues and organs in the developing organism during the process of gastrulation. Ectoderm develops into structures like the skin and nervous system, mesoderm gives rise to muscles and bones, and endoderm forms the lining of the gut and associated organs.
Epithelium is the connective tissue in a frog that lines the organs. It covers the internal organs and forms a protective barrier.
Animals that live in the shrub layer include small mammals like rabbits, squirrels, and chipmunks, as well as birds such as sparrows, finches, and thrushes. Additionally, insects like butterflies, beetles, and spiders can also be found in the shrub layer.
In a fetal pig, the mesentery is attached to the small intestines. It helps to support and hold the intestines in place within the abdominal cavity, allowing for movement and function of the digestive system.
Blubber is the layer of fat that keeps animals warm. These animals include polar bears, whales, and seals.
The serous membrane contains the epithelial layer and the connective tissue layer. The epithelial layer produces cells that produce lubricating serious fluid. The Connective tissue later houses blood vessels and nerves and serves as the "binding layer" for the serous membrane to adhere to organs and other structures in the body.
The double layer sheets of serous membrane that support the viscera are called mesenteries. Mesenteries hold organs in place within the abdominal cavity and provide a pathway for blood vessels, nerves, and lymphatics to reach the organs.
Many animals have a layer if skin to protect their organs. Dogs, cats, wolfs, elephants, birds, insects, and pigs all have a layer of skin that can protect their organs and keep them warm in cold climates.
The visceral peritoneum is the inner layer of the peritoneum, a membrane within the abdominal cavity. Organs inside the visceral peritoneum include the stomach, intestines, liver, spleen, and in females, the ovaries, Fallopian tubes, and uterus.
the body uses fat for many for example: the fat layer of our body keeps us warm. Fat is also used as padding and insulation for the organs and nerves.
serous membranes line the thoracic and abdominopelvic cavities and cover visceral organs. they are composed of thin sheets of epethelial tissue that lubricate, support, and compartmentalize visceral organs. serous fluid is the watery lubricant they secrete.
In higher vertebrates and some invertebrates (annelids, for instance), the peritoneum is the serous membrane that forms the lining of the abdominal cavity or the coelom - it covers most of the intra-abdominal (or coelomic) organs. It is composed of a layer of mesothelium supported by a thin layer of connective tissue. The peritoneum both supports the abdominal organs and serves as a conduit for their blood and lymph vessels and nerves. hope this answres you question

The peritoneal layer is the layer of tissues within the body that protects vital organs, particularly the intestines and surrounding organs.
mesoderm
The outer layer of the peritoneum that lines the interior of the abdominal wall is called the parietal peritoneum. This layer helps provide support and protection to the abdominal organs and helps reduce friction as the organs move against each other.
