In class Mrs.Gess always seems to be going back to the topic of sludgy blood. Every system can contribute to sludgy blood. All the term slugdy blood refers to is just that, our blood is thick and sludgy. When things dont make it out of our system and stay and get caught up in our blood our blood becomes sludgy. And hello, sludgy blood isn't good for our bodies. The sludgier our blood becomes, the hard it is for it to travel through our vessels, therefor increaseing our blood pressure, and no needs to have high blood pressure. There are many different things that can cause our blood to become sludgy: antigens aka bad guys, too much oxygen or carbon dioxide, differnet waste materials, and even too much water in our blood.

Objective 34: Lymph Nodes
Our lymphatic system has three different parts:
1.Lymph- a protien like fluid found throughout our bodies
2.Lymph Vessels-get the lymph where it needs to go
3.Lymph Nodes- little "stations" that clean the lymph as it circulates through the lymph vessels
The lymph nodes help to form the lymphatic tissues and organs. The lymphatic organs include:
1.Spleen-stores leftovers from redblood cells to be reused, stores platlets of blood, and just might be the fetus production house of red blood cells
2.Thymus-is the "babysitter' for T cells until they become mature enough to go fight off diseases. The thymus is the bowtie of the mascarade face from the respiratory section. It lies on the trachea and looks like a bowtie.
3.Tonsils-'security' for the pharynx, they capture pathogens trying to sneak into out bodies through our food and the air we breathe.
4.Peyer's Patches and Appendix- kill bacteria before it can get to our intestinal wall, they also have a unforgetting policy where they remember these bad guys and create new "memory' lymphocytes for the future so we will be ready for the enemy when it strikes again
Our immune systems major job is: to remember all of our "forgein invaders"and to recognize "self to non-self". Recognition of self to non-self is important because in some cases our bodys will startt to attack itself because it believes that it's not part of itself, this causes a number of different diseases.
It has two parts a more "superficial" defense and a chemical defense. The skin and mucosae make up the "superficial" defense. Once there is a breach in our "superficial" defense the chemicals start to fight the battle against pathogens. The pagocytes are called in to come eat up the bad guys along with the natural killer cells.

The lymphatic system is home to the lymphocytes, T cells and B cells. These cells are very important in defending our bodies against diseases and infections.
The lymphatic system helps set the foundation for the immune system.

Objective 35:Bottle Neck-Lymph Nodes
Mrs.Gess lined all of the students up in a bunch of lines and made us all run out the door at the same time, proving her point about the bottle neck shape of the lymph nodes.

Objective 36: Im watching you!!!!!!!

Our immune system is like the surveillence system of our bodies. As Mrs.Gess always reminds us in class, our immune systems are so unique because of their ability to recognize and to distinguish between self and non-self and because of it's memory. In our immune systems we have this protein called Major Histocompatibility Complex (MHC), this protein is divided into two parts, Class 1 MCH and Class 2 MCH. Class 1 MCH is found in all body cells, where as Class 2 MCH is found only in cells that deal with the immune system. Class 2 MCH eat up the bad guys in our bodies and then take a piece of the bad guy and show it off like a trophy. They do this so that the other cells in the body will be able to identify the bad guy. Mrs.Gess used an example of her defetinng Aarron, then she took Aarons sunglasses and put them on illustrating how the Class 2 MHCs defetes the bad guys then shows a piece of them off.
