First of all, you might want to spell DEFENSE correctly.

External defenses - Includes skin and mucous membranes. Internal defenses - Includes phagocytic cells, inflammatory responses, and antimicrobial proteins.
The body has three main lines of defense against pathogens. They are as follows:First line of defense: Skin, Mucous membranes, and Secretions of skin and mucous membranesSecond line of defense: Phagocytic white blood cells, Antimicrobial proteins, and the Inflammatory responseThird line of defense: Lymphocytes, and Antibodies
The body's first line of defense against pathogens uses mostly physical and chemical barriers such as sweat, skin, tears, mucus, stomach acid, and so on. Our skin and other membranes which line the body passages are fairly effective in keeping most pathogens out of the body. Mucus can trap pathogens, which are then washed away or destroyed by chemicals. Tears, sweat, and saliva all contain chemicals to destroy pathogens to some extent. There's multiple ways to organize the body's defenses. One way splits them into two parts: specific and nonspecific. Specific, also known as adaptive, is the last line of defense. This describes anything that targets the specific antigen, and not foreign substances in general. Specific includes lymphocytes, their antibodies, and the rather complex system that allows your body to become immune to certain invaders. The non-specific, or innate, immune system is the first line. This includes the first line of defense as described in the first paragraph, but also includes non-specific cells such as macrophages and neutrophils, which will eat and destroy just about anything it encounters that isn't a part of your body. Also included are the complement system, inflammatory response and interferons, which are left for another question.

Two crucial factors were Stonewall Jackson's immovable defense, which prevented Union troops from breaking the line, and the arrival of reinforcements by railroad.
There are many kinds of defenses, and some coaches use their own made up forms of defense. The most common forms of defense are zone, 2-3 defense (two players in a line around the free-throw line and three players in a line with one on the right wing, one under the basket and one on the left wing), 3-2 defense, 1-3-1 defense, man to man defense, and full press defense. You can also add any kind of trapping to any one of those defenses.
Three types of defense in basketball are: • Zone • Man-to-Man • a Hybrid of the first two (box and one, diamond and one, or triangle and two) - now what does this have to do with memorabilia?
You pass another line through both of them and measure the angles. If the first two lines form the same angle with the third line, the first two are parallel.
The film Secret Defense was a spy film that was first released in 2008. It gives a story of both a spy and a terrorist as they go through a conflict from two sides.
Nose Tackle. It's a position on the defensive line and is also called a nose guard or a middle guard. It's typically seen in the 3-4 defense, when the NT is the sole tackle on the lien of scrimmage, with defensive ends on either side. It can also refer to one of the two tackles used in the 4-3 defense. And in the older 5-2 defense, the line has two ends, two tackles and the NT would the be the middle tackle. The NT focuses on the center and one of the guards on the opposing team's offensive line.
