Tissue Structure: In a Nutshell (Nursing)

00:00 So to wrap up our lecture on the tissue level of organization, we find that a tissue is a group of similar cells that work together to perform a function. Cells of a tissue are often able to associate or communicate with neighboring cells via different types of cell junctions. There are 4 tissue types found in the body; epithelial tissue, connective tissue, muscular tissue, and nervous tissue. In this lecture, we focused on the first 2. Epithelial tissue is made up of cells that are densely packed into sheets. This is an avascular tissue that can cover or line organs or that can be glandular. Connective tissue is made up of cells and their extracellular matrix.

00:56 This is a mostly vascular tissue that is found all over the body. Finally, we have membranes.

01:05 Membranes are flat sheets of pliable tissue that cover or line a part of the body. They can either be epithelial or synovial. And this concludes our lecture on the tissue level of organization. Thank you for listening.
