Muscle contraction that results in a change in joint angle is called <span>concentric contraction.
This contraction occurs when enough force that can overcome the resistance applied is developed by the muscle where this force developed is larger than the force of the resistance applied.</span>
A white blood cell engulfing a bacterium is an example of blood functioning in protection.
<h3>What is a white blood cell?</h3>
White blood cells or better called leukocytes are blood cells produced in the bone marrow that belong to the immune system which are responsible for the <u>protection </u><u>and</u> <u>combat of infections and diseases</u>.
There are different types of white blood cells, among these are: <em>neutrophils, eosinophils, basophils, monocytes and lymphocytes</em>.
Usually the blood count of these leukocytes is used to detect situations such as infections, allergies, inflammation or leukemia.
Therefore, we can confirm that a white blood cell engulfing a bacterium is an example of blood functioning in protection.

In this situation, muscle cells ferment glucose to two molecules of lactic acid — again, with the net production of only two molecules of ATP per glucose molecule (Figure 16-6, left).
Next step, is to look more into it and explore the evidence.
