The vertebrate digestive tract, like that of invertebrates, is highly specialized in both structure and function for the digestion of a wide array of food. The basic components of the gut tube include the buccal cavity, pharynx, esophagus, stomach, small intestine, large intestine, rectum, anus/cloaca. A few vertebrates lack a stomach (cyclostomes, lungfish) but in most it functions for storage and acidic/enyzmatic digestion.
it is modified for fermentation in ruminant and pseudoruminant mammals. Absorbtion is the primary function of the small intestine in higher vertebrates, although some absorbtion occurs in the stomach and large intestine. There are three important glandular systems in vertebrate digestive system.
1-The salivary glands
2-The liver, gallbladder and bile duct
3-Pancreas and pancreatic duct
The liver is a large organ that secretes bile fluid.
Some mammals lack a gallbladder. Cephalochordates and cyclostomes lack a pancreas.
The large intestine of mammals is generally more developed than other vertebrates, is responsible for water reabsorbtion and formation of feces. Bacterial action in the hindgut can ferment cellulose and can synthesize vitamins. source: histology

Biogeochemical Carbon Cyles Video
Carbon is one of the key element of life. All life is about the carbon , so lets watch this usefull video about carbon cycle in nature.
Histology, The Science of Cells
The cell is the fundamental living unit in all life forms and the perfect example of nature’s genius operating at the microscopic level. From the first time when Anton Van Leeuwenhoek first observed cells under a microscope, the study of histology has come a long way. Histology is basically study of living cells and tissues under a microscope. As the science progressed, it was discovered that organisms such as Viruses which were much smaller than the most microscopic of bacteria were connected to the most gigantic of life forms by the same units known as cells.
Histology has helped identify differences invisible to the naked eye between animal and plant cells. The identification of a cell wall in plant cells which was absent in the latter has helped science delve into the fascinating regulatory mechanisms of plants. It has helped identify the causative agents of several dreaded illnesses and helped identify cures and immunization against many of them. It has helped understand and eventually, manipulate the life cycles of several microorganisms and plants leading to an industrial revolution of sorts that can boast of achievements ranging from cheese to Biofuel.
One of the biggest achievements of Histopathology has been in the field of medicine. From the use of humble stains to make cells visible to electron microscopy, the science of Histology has paved way for the detection and eradication several medical conditions. The latest diagnostic techniques and markers are being developed each day in a bid to improve the detection of conditions such as Cancer, Neonatal diseases, Genetic disorders. This is first step towards unlocking their cures in the future. Histology also forms an integral part of research aimed at plant and animal tissue culture. The science of Histology is our window to a fascinating world otherwise invisible to us.

CRG Histology Internal video
A new video from youtube about CRG histology and laboratory works.. very good video for histology and basic histology
Histology of Epithelial Tissue Video
great description of the main epithelial tissue types (simple and stratified) which are found within the bodyother histology videos which include more selective timings so, you arent waiting forever on a title slide to pass and slides with more information are shown for longer
