Lungs, Cross Section
Product Code : SCL-BLE-11674
Lungs, Cross Section (SKU SCL-BLE-11674) is a coloured prepared slide of lung tissue cut in cross section, used to show students the spongy network of air sacs where gas exchange takes place. It serves respiration lessons in secondary school biology, B.Sc. zoology and nursing or paramedical anatomy classes. Schools, colleges, training institutes, tender contractors and distributors can obtain it from Science Lab Supplies, which ships it out of Ambala, India.
Specifications
All specifications of the lung cross-section slide appear in the table. To summarise, the section is mounted on a rectangular borosilicate glass slide of 25.4 x 76.2 mm (1 x 3 inches), the preparation is coloured for contrast, and a plastic box is provided to keep the slide safe.

Applications and Experiments for the Lungs Cross Section Slide
Under the microscope the slide shows how lung tissue is built for gas exchange. Students trace the many thin-walled alveoli, the bronchioles that lead into them and the small blood vessels between them, and explain why a large, moist, thin surface suits the diffusion of oxygen and carbon dioxide.
- CBSE/NCERT Class 10, Life Processes: the human respiratory system and where exchange of gases happens.
- NCERT Class 11, Breathing and Exchange of Gases: structure of alveoli and the respiratory membrane.
- B.Sc. zoology, nursing and paramedical histology: identifying lung tissue and drawing a labelled section, then linking it to the bronchial tree on a Human Transparent Lung Segment Model.
- Class observation work on a monocular instrument such as the Junior School Microscope.
Standard Scope of Supply
You receive one coloured lung cross-section slide on 25.4 x 76.2 mm borosilicate glass, held in a plastic box. No microscope, model or chart comes with it; those items are listed separately and can be priced alongside the slide when a respiration unit is being equipped.
Packing, MOQ and Lead Time
A quotation can be raised for one slide or for a class quantity that gives each microscope its own copy. It will show the packing, delivery time and price for the number you ask for, and lung models or respiratory charts can be included on the same document.
Because it holds an Importer-Exporter Code, Science Lab Supplies can ship to buyers in South Africa, Qatar, Sri Lanka, Vietnam, Malaysia and Peru. Requests for this lung slide are welcome through the contact page and the enquiry cart, while public-sector and institutional bids are explained on the lab tender page.
Frequently Asked Questions
What does a cross section of lung tissue show?
It shows a honeycomb of small air sacs, the alveoli, separated by very thin walls, together with sections of bronchioles and blood vessels. Students use it to see how the lung provides a large surface for gas exchange.
How does the slide fit with lung models in teaching?
Models show the lungs and bronchial tree at visible scale, while the slide shows the tissue itself at microscope scale. Using both lets students connect the airways they handle on a model with the alveoli they see through the eyepiece.
Who supplies the Lungs, Cross Section slide?
Science Lab Supplies handles supply from Ambala, India. As a school laboratory equipment supplier in India it can bundle this slide with microscopes, respiratory models and charts, so a school or college receives one combined quotation and shipment.
What are the physical details of the slide?
The slide is rectangular borosilicate glass measuring 25.4 x 76.2 mm, carries a coloured lung section, and is delivered in a plastic box. It is intended for laboratory use with a compound microscope.
