Answer:
how cilia helps columnar epithelium tissue in absorption?
Columnar cells also have an important role in the digestive tract .
These cells line the intestines and are responsible for absorbing nutrients from digested food. Columnar epithelial cells in these cases often have multiple finger-like projections, which increase the surface area of the cells.
why your calf muscles pain if you walk for long or climb too many steps?
The Achilles tendon, which connects your calf muscle to your heel, can be irritated by walking too much, especially if you don't build up to it. Repeated flexing of the foot when walking up and down steep hills or on uneven terrain can also strain the tendon, triggering lower leg pain.
