Description
A Cockroach: Blood Circulation, Respiratory, & Nervous System chart (55×90 cm) is a large-format, multicolored educational wall chart illustrating three critical physiological systems of the cockroach—essential for biology classrooms, NEET prep, and zoology labs.
Chart Features and Content
Size and Material: 55 × 90 cm, printed on 80 GSM map litho paper, often thermally laminated for tear, water, and dust resistance. These charts are durable and suitable for classrooms and labs.
Blood Circulation (Circulatory System): Shows the open circulatory system with a long dorsal heart, anterior aorta, segmental ostia, sinuses (pericardial, perivisceral, perineural), alary muscles, and the direction of hemolymph (blood) flow.
Respiratory System: Diagrammatic view of the branched tracheal tubes, main tracheae, and the ten pairs of spiracles (openings) on the lateral side. Includes details of air sacs and tracheoles for direct gas exchange, showing air movement and spiracle function.
Nervous System: Clear labeling of the decentralized nervous system—with brain (supraesophageal ganglion), subesophageal ganglion, ventral nerve cord, segmental ganglia, and branching nerves, demonstrating both central and peripheral control.
Color Coding and Labels: Each system is usually color-coded for clarity (e.g., red/blue for circulation, green for respiratory, yellow/orange for nervous pathways), with key parts annotated in English and sometimes in Hindi for broader accessibility.
Functional Notes: Some charts include legends or side panels summarizing functions of each system or key anatomical features—helpful for conceptual learning and quick visual reference.
Educational and Catalog Use
Widely used to teach insect physiology and comparative anatomy. Essential tool for practical classes, revision, and reference in biology textbooks and competitive exam preparation.
Meets institutional standards for scientific accuracy, visual clarity, and long service life.
For digital or catalog inclusion, high-resolution, scientifically accurate charts can be sourced from reliable educational suppliers and biology chart manufacturers.
