Now we're going to discuss the connective tissue. Now here's a connective tissue. The connective tissue consists of cells and the extracellular matrix.
Again, there's a close relationship between the connective tissue and the extracellular matrix. The cells in the connective tissue rarely touch each other. As you can see, In the way, for example, in the skin, in the dermal layer, you can see there the cells in the extracellular matrix are far from each other. The extracellular matrix here consists of ground substances and fibers.
The ground substance is between the fibers. This one here. Actually, it's not a very important concept for you.
The term collagen and proteome like us is more important. This is just nice to know. Then, The connective tissue is vascularized. So, see, it's vascularized, it can provide nutrients. So, ano yun?
Ano yung mga ano natin? Ano yung laman ng ating connective tissue? So, this is the connective tissue, or if you're going to zoom, make a diagram of the extracellular matrix, itong may kita nyo.
we have here the blood vessels we have thin brush elastin fibers no we have the collagen fibers okay we have fibroblast which are the one that produces your collagen no and you have here the growth substances no that will spaces no and okay then we have the different types of connective tissue there are 12 types of connective tissue but we can uh categorize them into three one two three first is the connective tissue proper supportive connective tissue and the fluid connective tissue okay let's start with the supportive connective tissue why? if you're going to know kung alin yung list yung mga pp naka konti The rest, it's in the most. Okay.
Now for our supported connective tissue, you have to remember hyaline cartilage, fibrocartilage, and elastic cartilage. Now as you can see, there is a word cartilage in the names. We have hyaline cartilage, fibrocartilage, and elastic cartilage.
Okay. While your fluid and connective tissue is on the blood and the lymph. Okay.
That's the blood. You can see that it's in the cardiovascular system. and the lymph in the lymphatic system.
Lymphatic. Okay, the rest, you can now associate it with the connective tissue properly. So what are the rest of those?
It's the areolar, adipose, reticular, dense irregular, dense irregular, and dense irregular connective tissue. Okay? So what's my tip here?
Remember to support it with the fluid. then the rest will now fall into your connective tissue proper again so supportive tissue known to the words with cartilage okay by your flood fluid and connect fluid connective tissue the blood and the lymph which is correlated to your cardiovascular system and the lymphatic system okay these are just examples no okay so what is the function of your connective tissue so we have here the fibroblast now the fibroblast produces the fibers in collect in the extracellular matrix now for example collagen which is the strongest fiber then we have the elastic cartil elastic elastic elastic or elastin no elastin which provides elasticity and the reticular fibers which are branching fibers that support the internal organs okay so here is the function of collagen strongest fibers elastic fibers elasticity with the word elastic while the reticular these are branching fibers It looks like spider webs. Then we have the adipocytes.
The adipocytes store energy and provides cushioning. In short, these adipocytes are just other term for fats. So fat is storage of energy. It's your lipids.
Okay? Then cushioning. It's just the fats are soft, right?
Is this important? Yes. Does it serve as protection?
Yes. Because it softens impact. It softens impact.
then we have here the white blood cells and the components of blood components of blood so the function is provide immune function white blood cells immune function then we have the red blood cells and again in blood so the function is to release gases such as oxygen and carbon dioxide okay now here other cell type that can be found in your connected tissue proper Again, we have the fibroblasts, which produces extracellular fibers and ground substances. The plasma cells, which is a white blood cell that produces your antibodies. We have the lymphocytes, also eosinophilic leukocytes, neutrophilic leukocytes, and macrophages.
And we have the cisplasophilic leukocytes, which are all white blood cells. I have to erase a lot of them. From your plasma cells to the basophilic leukocytes, except your mast cells, except these are your white blood cells. As you can see here, we have leukocytes.
Leuco means white. Cytes means cells. These white cells, they're white blood cells.
Leukocytes, then leukocytes. the macrophages is also um the macrophages is also a white blood cell okay as you can see your function is more as an immunity the plasma cells antibodies the lymphocytes no immune immune immunity then defense functions the eosinophilic the eosinophil no allergies and also defense against parasites in short immunity potential that's an immunity then we have the that deeper side so this is storage energy storage okay
