What would happen to a person blood osmolality when drinking seawater?
When you drink seawater, a high concentration of salt finds its way into your blood vessels. As a result, you have a higher concentration of solutes (salt molecules, in this case) on the outside of your blood cells than in your blood cells-- there is a hypertonic solution on the outside of the blood cells. Your body wants to keep solutions isotonic across the membranes-- that means your body wants the same amount of free water molecules on the inside of the blood cells as the outside-- so water molecules move out of the blood cells in order to keep the balance of free water molecules. The water moving out of the blood cells cause them to "crenate," or shrink, which is of course not very good for your cells.
What is free surface?
An epithelium always has on surface where the cells are exposed either to the external environment or to an internal passageway or cavity; this surface is called the free surface of the epithelium.

What makes antibodies in the body?
Yes, by certain white cells in the blood. Some of these cells produce free floating antibodies while others present their antibodies on their surface receptors. These different systems fight infection by different kinds of organisms.
What is microvilli'?
Tiny projections on the free surface of some epithelial cells; increase surface area for absorption
What is the function of human epitheal cells?
Epithelial cells found on the surface. They cover the and line the free surfaces.
How will you keep your blood vessels free from deposit?
Stay away from fats and high cholesterol and exercise regularly.
Why should urine be free of blood cells?

What large phagocyte white cells that spend most of their time outside the blood as fixed and free phagoctic cells?
monocytes
What is in blood other than the cells?
The plasma (liquid part), free antibodies, etc.
Cells that free calcium from bone to maintain blood calcium levels are called?
