Spirit levels can have several possible colours of fluid, including yellow, blue, green and red. The fluid used is often naturally clear, with a dye added. Yellow is the most common colour. This may be because yellow and black (the colour of the lines marked on the tube) are a very good contrast.
In the Dynamo Theory, the magnetic field of the earth is created in the outer core. The fluid contained in the outer core creates and maintains the magnetic field during rotation.
In physics, net force refers to the overall force acting on an object. A feather with no net force on it maintains constant velocity.
A feather with no momentum maintains constant velocity. Momentum is defined as the quantity of motion of a moving body, measured as a product of its mass and velocity.
A force that maintains motion is called inertia. This is the same as to what is normally referred to as momentum.

Sodium maintains the balance of fluid in a person's body.
major fuel source for cells Maintains blood glucose levels.

When the body maintains a steady internal environment, that is called homeostasis.
the pancreas secretes insulin which maintains body sugar levels.
Potassium is an electrolyte (a substance that maintains your body's fluid levels). It helps regulate blood pressure and heart function. Research shows that increasing your potassium intake can lower your blood pressure but too much can derange your electrolyte balance and slow your heart down, sometimes to dangerous levels.

The protective function? Well I guess there isn't really specific protective function because blood flow maintains the life of the organism, and also maintains hormone levels, body temperature, blood clotting to prevent blood loss, and much more.
It is the placenta. It is a temporary endocrine gland
