Wednesday the 13th

Today in 2nd period biology we discussed the Kidney. Some of the notes for today are the following...

The kidney

- Removes metabolic waste and helps to maintain homeostasis (i.e. keeps salt and water levels in balance)

- Three major steps the kidneys preform are...

- Filtering blood

- Reabsorbing nutrients

- Collection and excretion

- The nephron

-Basic unit of the kidney

- Filtration

- water, Urea, glucose, salts, amino acids and vitamins filter into nephron

- Reabsorption

- needed materials reenter the blood stream

- Collection and

- concentrated urine is collected and leaves the kidney

The second half of class we saw a urine demonstration were we tested for glucose.

There is no homework due tomorrow but there is a test friday on digestion and excretion. The homework that was due today was the kidney dissection lab on pages 23-28 in the unit packet.
