Objective 2: Pimples

One day in class during lecture Mrs. Gess was talking about blood and how the white blood cells help in defending our body against infection. Well as we were talking she said something about the macrophages, well macrophages when they die turn into pus. Now every time I see a pimple I think about popping it to see the dead macrophages.

objective 2: Centrifuge

The other night my mom and I were watching House and the girl doctor was using a centrifuge machine to test one of the patients blood. it was soo coll because I asked mom if she knew what that was and ofcourse my mom didn't know what it was, so I was able to tell her what it does- that its used to separate the different components of blood so you can see what is in the blood. I just thought that was so cool, plus she thinks im smart now, lol.

Objective 2: Everywhere I Go I See Anatomy & Physiology


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 3

At first I didn't really like the Physio ex. assignments, I just thought they were dumb and time consuming. However, after Valerie started asking me questions I was able to answer correctly, not because I remembered from lecture but because I had just saw the results of different hormones on my Physio ex the night before. She was asking me about estrogen  and how it relates to the follicle stimulating hormone. I remember reading in the lab book in the Physio ex. portion about how the FSH is what stimulates the production of estrogen.

This is Mrs. Gess showing up precipitation. It's hard to believe even for her but you can break the bonds of water and create a solid. The precipitants are the "damdruff flake" floating around in the bottom of the tube. Sssooooooooooooo cool!!!!!!

Objective 8: Safety


In Anatomy our group always tries to follow all the safety precautions while we are in the lab. Here are a few pictures that help demonstrate how you're supposed to handle thing in the lab.






Before and after lab we always clean our table with a 10% bleach solution,because you never know if the people before you cleaned the table whenever they left and we don't know what they may have used the table for. We clean it after lab even if we haven't disected anything or used any chemicals.

We always wear our goggles and lab coats when we are disecting anything. The hat was jus extra that night.

We always place the microoscope back in the bags, and place the back in the cabinets where we got them from.

Objective 9: ok now I think I understand these bonds a little bit better

I loved the illustration Mrs.Gess did in class with Ashley and Mike.
#1 Rule. Greedy,Grabby, Gassy=boys
Mike represented oxygen, Ashley and Mrs.Gess represented Hydrogen
Mike wanted their electrons but they were like yeah right whatever we're not giving them up so Mike tried to take them anyways but they never let go, so that shows that water forms a polar covalent bond.
Polar=pulls
Covalent=sharing
Hydrogen=giving
Oxygen=give me, give me, give me
This concept just now clicked after the illustration in  class and after Val further explained it to me. I see now after lecture why this type of bond is so important in water.

Objective 12: Hormones and Functions of the Hypothalamus-Pituitary Complex

How I remember what it does- posterior kind of sounds like postage and the  posterior pituitary gland is used for storage. This is just a quirky way that i remember what the posterior pituitary gland's function is.

The anterior pituitary gland has about 6 different hormones:
Growth Hormone-too much of this hormone can cause gigantism in children and adults, on the flip side too little of this hormone can cause dwarfism in children. It effects the liver, muscles, bones, cartilage, and other different tissues.
Thyroid Stimulating Hormones- too little in the body can cause hypothyroidism, in adults extreme hypothyrpoidism is called cretinism and in adults it is called myxedema. Too much of this hormone can cause Hyperthyroidism.
Adrenocorticotropic Hormone- its job is to signal the adrenal cortex to release glucocorticoids and androgens. It is very rare to not have enough of this hormone, however having too much can lead to Cushing's disease. 
Follicle-Stimulating Hormone- it's job is to tell the ovaries and testies to start producing estrogen and sperm. Unfortunately if we dont have enough of this hormone we will be unable to have children, but having too isn't gonna be a bad.
Luteinizing Hormone-  also helps with the production of estrogen in females, but also with  triggers ovulation in females as well, in male it tells the testies to start making progesterone and testosterone. It effects are the same as the above, too much is a good thing but too little can be devestating for some.
Prolactin-tells the secretory tissue of the breast to start lactation, an insuficiency can cause problems in nursing women, too much cause too much milk production (galactorrhea) and is "impotence in males".

 The Posterior Pituitary Gland has about 2 hormones:
Oxytocin- tells the uterus to contract, starts off the labor contractions, and starts off the spill of milk in the breast. The effect of having too much or too little is unknown,
Antidiuretic Hormone- tells kidney when to reabsorb good ole H2O, too little can cause deabetes insipidus, too much can cause "Syndrome of Inappropriate ADH secretion"
