There are 16 very long malpighian tubules present at the junctions of midgut and hindgut.
Grinding of food is carried out only by the mouth parts.
Nervous system is located ventrally and consists of segmentally arranged ganglia joined by a pair of longitudinal connectives.
Females bear a pair of short thread like anal styles.

Tight junctions help to stop substances from leaking across a tissue.
Adhering junctions perform cementing to keep neighbouring cells together.
Gap junctions facilitate the cells to communicate with each other by connecting the cytoplasm of adjoining cells, for rapid transfer of ions, small molecules and sometimes big molecules.

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.
It exerts the greatest control over the bodys responsiveness to changing conditions.
Chondrocytes, the unit of neural system are excitable cells.
Neuroglial cells protect and support neurons.
When a neuron is suitably stimulated, an electrical disturbance is generated.

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.

dense irregular connective tissue
elastic cartilage

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.
