Frequently Asked Questions
Why do some epithelial tissues have cilia?
Cilia are microscopic hair-like structures that move in waves. In the respiratory system, cilia move mucus and trapped particles up and out. In reproductive organs, cilia move the egg. This is more efficient than waiting for diffusion.
What is the difference between tendons and ligaments?
Tendons connect muscle to bone and are made of dense connective tissue aligned in parallel. Ligaments connect bone to bone. Both must withstand tension, but tendons must transmit force efficiently while ligaments must prevent excessive joint movement.
Why is blood considered a tissue?
Blood consists of cells (red and white blood cells, platelets) and cell fragments suspended in plasma, which is the extracellular matrix. This fits the definition of tissue as a group of similar cells with an extracellular matrix.
