One surface extension from the plasma membrane is Cilia. Cilia are hair-like structures. Its function is still a mystery, but in some cases it is a sensory, serving as "antenna" for monitoring nearby conditions. One responsibility is protecting a person from germs in the lungs.
Osmosis pressure, the heart drives water out of the smallest blood vessels by reverse osmosis. Water leaves the capillaries by filtration but this is balanced by water moving back to the capillaries by osmosis.
One non-membraneous organelle is the ribosomes. Ribosomes are responsible for synthesis of proteins from amino acids. They assist in the process of joining amino acid together to form
