Inflammation

Inflammation is the defensive response of our body's tissue damage. The four characteristics signs and symptoms of inflammation are redness, pain, heat, and swelling. It can also cause a loss of function in that area. Inflammation is the attempt to dispose of microbes, toxins, or foreign material at the site of injury. To prevent the spread to the other tissues and to prepare for tissue repair. There are 3 basic responses to inflammation which are: Vasodilatoin and increased permeability of blood vessels. Next, the movement of phagocytes form the blood into the interstitial fluid and lastly, tissue repair.

This seems a lot like when i sprained my ankle. My ankle was red, in a lot of pain, and was swelling the size of a softball. At this time, my body was trying to fix my ankle when it knew something was wrong. After spraining it, i had to elevate it every once in a while, and put ice on it to reduce swelling. This helps get the blood lowing threw the site of inflammation. Before long, i was able to walk on it, and begin doing my everyday activities again.

HPV and Gardasil

Gardasil doesn't contain any of the HPV virus. It's made up of virus particles, and stimulates the body to make antibodies, and recognize them to fight the HPV. Gardisil gives traits of the HPV so the body makes the correct antibodies. The Gardisil protects against four types of HPV. There must be enough antibodies in the blood when exposure happens. The antibodies end up staying in the body for a period of time. There are three shots given to ensure enough antibodies are made and remain in the blood.

This has a lot to do with me for one because i have gotten all 3 of the Gardasil shots. My doctor recommended it with i was 17 because its more common in younger girls. Also, one of my friends has a form of HPV, and she was going to get the shots when she found out, which i found very strange. Since i got the shots, i haven't come up with any kinds of infections. Before, i would get UTI's and once i had a really bad kidney infection.

The Eye

The eyes have a lot of different parts to it. The major ones are the cornea, pupil, sclera, the eyelash, lens, choroid and retina. The cornea have no blood vessels. The lens is held in place by suspensry ligaments which connects to ciliary process and ciliary muscle both are called the ciliary body. The sclera is fibrous tunic, which is highly vascular. The choroid is the pigmented tunic which is also highly vascular and the retina which is the visual tunic that is not vascular at all. Parasympathetic nerve impulses, circular muscles relax, radial muscles contract, the pupil dilates, and more light enters eye.

The eye has a lot to do with my everyday life. I have the worst eyes ever. Don't know how or why, maybe i sat in front of the TV to close i don't know. I am near cited, therefor i have to where contacts all the time, if i take them out i cant see 3 ft. in front of me. I don't know why exactly people lose there eyesight. i wish i hadn't, because contacts and glasses are a pain. But you gotta deal with whatever life throws at you. I'm also not aloud to drive without contacts or glasses, if i get caught driving without them i can get a hefty fine or even lost my licence.

Lymph nodes

Lymphatic capillaries are like jigsaw puzzle shape cell's connect oxygenated and deoxygenated vessels. Fluid moves towed end of lymph node. There dead end or blind ended vessels. Closed ended means not connected to anything else. The lymph fluid moves form Skeletal muscle pumps. Efferent vessel directs to the lymph node. There are 3 major area's where the lymph nodes are. The cervical nodes, axillary nodes, and inguinal nodes.

Lymph nodes are important for protecting our bodies from harmful diseases. There supposed to help filter them away. My boyfriend had swollen lymph nodes in his cervical area and inguinal area. At first we didn't know what it was, but when i took him to the doctors, he was told it was swollen lymph nodes and it was caused by some infection in his body, and the lymph nodes are trying to fight it off. He ended up giving him medicine, and the swelling went down. In some way the nodes where trying to fight his infection, and by doing that they where swelling.

Heart

The heart has 3 layers, the Endocardium, Myocardium and Epicardium. The Endocardium is made up of simple squamous Epithealial. The Myocardium is all cardiac muscle, and the Epicardium is the visceral layer. Also theres the great cardiac vein, which is anterior to interventicular artery. The right atrium receives blood from 3 veins, the superior vena cava, inferior vena cava and the coronary sinus. The interatrial septum separates the right and left atria, and has the fossa ovalis, a shallow depression that is a renant of the feta foramen ovale. The tricuspid valve lies between the right atrium and the right ventricle where blood passes as it flows from the atrium to the ventrical.

The heart is very interecting to me. There is so much to know about it, that its hard to keep up with it all. The heart is probably the most vital organ that we all have. Without it we wouldnt have blood pumping from our heart to all other regions to our body and back to the heart again. My step father's dad just died from a heart attact. It was believed to be cause by anestesia from having knee surgery. He had already had a previous surgery on the heart.

White Blood Cells

There are 5 different catagories of White Blood Cells. The first one is Neutrofulls, which are the most commen, the second are the Lymphocytes, which are made up of T-cells, helper sells and killer cells, and CD4, CD8, and B-cells. Next is monocytes, which are macrophage's. Eosinophil, is protozona and worm deiseas, like filarysisis. Basophil is next, and there are less then 1/10 % in white blood cells. Also basophile has graunals of histomine, vasodilation of blood cells, drop blood pressure, and could be life treatning.

These blood cells have a big effect on our lives. With the lymphocytes, CD4 count, if it fals below 200 + 1 mc you will have aids. Without the lymphocytes, we woundnt have them filtering out the possible deseases that we can get. It also plays a major roll in blood clotting, without them, we could get blood clots everyday. The clotting is proteins in an inative state but have to be activated when homeostasis occurs..

Red Blood cells

We have two different kinds of blood cells Red and White. Red blood cells have no nucleus and are made in the red bone marrow. Closest to the trunk, radius, ulnar, femur, and flat bones like the skull. There's the erythroblast, and erythrocytes. The red blood cells leave the red bone marrow s in the blood for 24 hrs, they eject the nucleus, which is why they don't have one, and then they become nucleotides then back to the beginning. the liver and spleen get rid of extra red blood cells, and they cant repair themselves because they have no nucleus. there phagocytized in the spleen and liver for 90-100 days. They just float around for a while.

Red blood cells are very important to our life. For one there made in the red bone marrow, which bone marrow is used for cancer patients. When someone has leukemia they need they usually need a bone marrow transplant. That's where the red blood cells are made. When i was little my cousin have leukemia, she needed kemo and a bone marrow transplant, she was only 5. I don't really remember this but i have pictures of her with no hair. We also need the red blood cells to transport atoms of oxygen.
