Observations
Pancreas 1X
A cross section of the tissue in the pancreas.
Pancreas 4X
The Islets of Langerhan contain endocrine cells
that secrete the hormones insulin and
glucagon.
The exocrine aciner cells secrete digestive
enzymes and bicarbonate into the intestines.
Pancreas 10X
There are separate cells found in the pancreas.
The endocrine cells secrete hormones into
blood or lymph. The exocrine cells secrete to
the surface of a tissue.
Pancreas 20X
The insulin secreted by the cells of the
pancreas promotes protein synthesis.
Pancreas 40X
The enzymes secreted by the cells of the
pancreas aid in the digestion and absorption
that takes place in the small intestines.
Intestine 4X
The epithelium found in the intestines is made
up of varying kinds of cells. The cells that make
up the villi are the most abundant. These cells
function to absorb nutrients during the
digestive process.
Intestine 10X
The intestines also contain fibroblasts. These
cells are part of the connective tissue that
provides support to the intestinal canal.
Intestine 20X
Like all organs, the tissues of the intestines
receive oxygen and remove waste by blood
carried in arteries and veins.
Intestine 40X
The intestines are lined with smooth muscle
that contracts involuntarily to move the
digested food through the intestinal canal.
