HAPPY THURSDAY

Today in class we...DISSECTED A SHEEP HEART!!

Before we dissected the heart we had to take a quiz :( Luckily I didn't have to take it because I wasn't in class on Wednesday, so I don't really have much to say about it. Sorry

In the dissection we had to locate the pulmonary artery, which happened to be on top of the heart, and the coromary arteries, which were located in the fat on the heart. Before we could slice and dice the heart we had to show Ms.Stein that we knew the right side of the heart from the left side and locate the right and left ventricles and the right and left atriums.

We found out that if you stick one finger in the pulmonary artery and another finger in anotehr hole in the heart far enough then your finegrs will touch!!!

Homework:

1) Read 33.2

2) Four Corners Sheet

3) Finish the Heart Lab if you didn't finish it in class


THE NEXT SCRIBE IS...

MICHELLE

Happy Passover!

Today in Bio we started off by getting our UP (11-17) pages that we annotated and then filled out the questions for stamped. After getting our homework stamped we took a bunch of notes on the heart, circulation and Blood vessels. When we talked about the circulation in humans we figured out that humans have a four chambered heart (2 ventricles on bottom and 2 atriums on top), we also have double loop circulation which means the blood not only circulates through our body it, also circulates through your lungs as well. We then reviewed the heart diagram we were given and named all the parts to review for our quiz tommorow (no word bank). Then we started our coloring homework at the end of class (not all diagrams need to be labled!).

Parts on Diagram:
Supirior Vena Cava
Infirior Vena Cava
Pulmonary Vein
Pulmonary Valve
Pulmonary Artery
R/L Atrium
R/L Ventricle
Tricupsid Valve
Septum
Bicupsil Valve
Aortic Valve
Aorta
Desending Aorta
Where you would find Oxygenated blood and Deoxygenated blood

Flyer Than Aladdin :)

hey hey hey it's tuesday :)

today in class we started off by getting a new unit packet, a new calendar , and we turned in our cornell notes from 33.1. we got grade reports and we got back a flow map! then we did up page nine and ten in groups and when we were going over the answers Olivia had this bizarre question..I believe it went as follows (correct me if i'm wrong): "Mrs. Stein, scientifically, which is more likely to be real a werewolf or a vampire?" and mrs. stein gave a one word answer : Vampires. And I think I know why. Some people become so obssesed with them that they start drinking blood which turns their obssession into a mental illness, so they truely believe that they are vampires which I guess makes it more probable that they exist. I mean i guess it's what you define vampire as because some believe they never sleep and others say they sleep upside down. yay or nay?
Moving on, we watched a video as we walked in and at the end of class and both were on the circulatory system :)

i'm sorry that this was mostly about olivia's question but to be honest we didnt do a whole lot in class
homework:
up pages 11-17 read +annotate (underline and write in the margins)+ answer ?s on page 17


the next scribe is Olivia :)

Halfway through the Week

Today, we started off class by turning in our kidney dissection worksheets and with Mrs. Stein selling some hope bands. (Which people should wear on Friday!) Then we continued by taking some notes, about the kidney and the nephron. This is the nephron picture that Mrs. Stein on the powerpoint:

The Nephron is the basic unit of the kidney. In it filtration and reabsorption happen. Filtration- water, urea, glucose, salts, amino acids, and vitamins filter into the nephron.Most proteins and blood cells remain in the capillary. Reabsorption- needed materials re-enter the bloodstream Collection- concentrated urine is collected and leaves kidneys via ureters.

Kidney:

• 
  
  
  The kidney removes metabolic wastes



• 
  
  
  Maintains homeostasis: - it keeps salt and water balance

3 steps: 1.) Filtering blood 2.) Reabsorbing nutrients 3.) Collection and excretion of urine

And then at the end of class we did pages 17 and 18 in the UP.

After that we did an experiment with urine to check what was in it. Jacob and Sam were the helpers and I also think Jacob ended up tasting one of the urine samples!!

Homework: Test is on FRIDAY!

KIDNEY DISECTION!

IN CLASS:
-Discussed rules and expectations of the kidney dissection
-Kidney dissection

HOMEWORK:
-Finish kidney dissection lab (UP 23-28)
-Unit test on Friday

KIDNEY DISSECTION:
The dissection was not bad at all. We had to cut off the fat tissue and then cut the kidney in half and examine and figure out the different parts. Then Mrs. Stein quizzed each lab group by pointing to a part of the kidney and asking each person what she was pointing to. All in all i think it wasn't too bad and everything went pretty well. Most people finished early. Also, if you were not in class today you are still able to complete the questions that go along with the lab.

OMG IT'S MONDAY!!

GREAT STUFF YOU GUYS!! KIDNEYS!! :D Ok... we've started the class by getting two stamps for UP 19-20 and the Lab we did last week. Tomorrow we will be dissecting a sheep KIDNEY!! I can barely hold my excitement :] Next we answered these questions on the board: 1) What organs are the part of the excertory system? 2)How does the excretory system play a role in homeostasis? 3)What does the cartoon below illustrate? What does it do? (I couldn't find the exact picture but this was close enough.) Answers... 1) Liver, skin, kidneys, and lungs. 2) Balances the body to keep metabolic wastes out. 3)A nephron, it is the functional unit of the kidney (it filters the blood) Next we went over our lab and the results of the nutrition test.

Please make sure you get the correct results from a friend....

-For the bread, it should defiently be positive for starch but everything else could be either or... Bread is a fortified food.

-If you tested cheese for starch (which you didn't have to..) it would test positive (which shouldn't) but the powder on the cheese that prevents it from sticking to eat other is the only thing that has a starch compound in it..

-Why is there no fat in potatoe?? Potatoe is full of carbohydrates and if you don't consume the energy you get from it it is store and converted to fat...

We also took some notes.....

Excertion -The removal of metabolic wastes from the body. -CO2, salts, water, nitrogenus waste, uric acid and urea -Excertory organs - lungs remove CO2 - skin removes salt, water, and some urea - kindeys are the main excretory organ Excretory System -Renal arteries carry "dirty" blood from the aorta to the kidneys. (Unfilterd blood) -Renal veins carry "clean" blood from the kidneys to the inferior vena cava -Ureters carry urine from the kidneys to the bladder -Urethra carries urine out of the body. We were suppposed to watch some videos afterwards but youtube wasn't working... OUR HOMEWORK.... -Read over our kidney dissection UP 23-28. -Tomorrow is the last day to visit Mrs. Stein for a homework pass. -Test Friday STUDY!!!! :O Next scribe shall be..... Ariana !! :D
