Объяснение:

Connective tissue(CT) is one of the four basic types of animaltissue, along with epithelial tissue, muscle tissue, and nervous tissue. It develops from the mesoderm. Connective tissue is found in between other tissues everywhere in the body, including the nervous system. In the central nervous system, the three outer membranes (the meninges) that envelop the brain and spinal cord are composed of connective tissue. They support and protect the body. All connective tissue consists of three main components: fibers (elastic and collagenous fibers), [1]ground substance and cells. Not all authorities include blood[2] or lymph as connective tissue because they lack the fiber component. All are immersed in the body water.

The cells of connective tissue include fibroblasts, adipocytes, macrophages, mast cells and leucocytes.

The term "connective tissue" (in German, Bindegewebe) was introduced in 1830 by Johannes Peter Müller. The tissue was already recognized as a distinct class in the 18th century

Answer 2

The type of tissue that is predominantly present in the pancreas is epithelial tissue. The pancreas is a glandular organ that serves both endocrine and exocrine functions.

In terms of its exocrine function, the pancreas produces and releases digestive enzymes into the small intestine to aid in the breakdown of food. These digestive enzymes are synthesized and secreted by clusters of cells called acinar cells, which are a type of epithelial cell. These acinar cells form the majority of the exocrine tissue in the pancreas.

Additionally, the pancreas also has endocrine functions, as it contains specialized regions called islets of Langerhans. These islets consist of different types of endocrine cells, including alpha cells, beta cells, delta cells, and others. These endocrine cells secrete hormones such as insulin and glucagon into the bloodstream to regulate blood sugar levels. Again, these cells are of epithelial origin.

Connective tissue and muscle tissue are not the predominant types of tissue found in the pancreas. While the pancreas does contain some connective tissue to support its structure and blood vessels, the majority of the tissue is composed of epithelial cells due to its glandular and secretory functions. Muscle tissue is not a significant component of the pancreas as it is not involved in its primary functions.
