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...

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:
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!
