It is an epithelial tissue.
It is composed of a single layer of cube-like cells.
They are found in the walls of blood vessels and air sacs of lungs.
Secretion and absorption are the main functions of these tissue.
Lateral heart. It is a blood pumping organ.
Calciferous glands. They neutralize the humic acid present in humus.
Nephridia. It regulates the volume and composition of the body fluids.
Blood glands. They produce blood cells and haemoglobin which is dissolved in blood plasma.

Each muscle is made of many long, cylindrical fibres arranged in parallel arrays.
Muscle fibres contract (shorten) in response to stimulation, then relax (lengthen) and return to their uncontracted state in a coordinated fashion.
Muscles play an active role in all movements of the body.
