No, blood is a part of an organ system, known as the cardiovascular system.
Reasoning:

2. Blood does have tissue, and it is called <em>connective tissue</em>. This is only sometimes. However, an organ consists of <em>many</em> <em>different </em>tissues.
3. To go with point 1, since blood is a fluid, there is no structured organization.
4. Organs <u>must</u> be solid or <em>gelatinous</em>.
In summary, blood is <u><em>NOT</em></u> an organ.

The whole world needs to work together, sooner rather than later, in order to gradually switch to energy sources that will be economically jutifiable but also environmental friendly, as if everything continous as until now the consequences will soon be irreparable and everyone will feel them.
