What is the transparent tissue that covers the heart called?
The pericardium. It is composed of two layers: the fibrous pericardium (the outer layer that is made of tough connective tissue) and the serous pericardium (the inner layer in which serous fluid provides lubrication for the heart to beat with almost no friction).
Arthropods have a hard outer skeleton and?
Yes. Arthropods are characterized by an exoskeleton made mostly from the tough protein chitin, also joint appendages and segmented bodies.
What does the percardium do?
The pericardium is a tough double layered fibroserous sac which covers the heart. The space between the two layers of serous pericardium the pericardial cavity, is filled with serous fluid which protects the heart from any kind of external jerk or shock.
Where is an arthropods skeleton?
Arthropod have exoskeleton. The exoskeleton is composed of a thin, outer protein layer, the epicuticle, and a thick, inner, chitin–protein layer.
