This slide presents a transverse section through the intestinal region of an earthworm, stained with H&E to highlight tissue layers. Under the microscope, students can observe:
- Typhlosole: Internal fold increasing surface area for absorption
- Intestinal lumen: Central cavity for digestion
- Circular and longitudinal muscle layers
- Coelomic cavity and epidermis
- Dorsal and ventral blood vessels
The 10 µm thickness allows for crisp visualization of internal structures, making it ideal for comparative anatomy and invertebrate physiology lessons.
