Seventh Grade Week 14

This week we continue looking at the Human Body. Remember, as we go through this entire unit, add to, redo, edit your Human Body Notebook 10 projects. Send it to hoopmanscience@gmail.com. This week as a class we are editing and adding to the pages on the digestive and urinary systems.

Compare and contrast mechanical and chemical digestion?
What is a vestigal organ(like the appendix)?
How do the kidneys filter blood?

Contracts for this week focus on these questions. Use the Human Body Google Doc we created as a list of resources to use in your research and use lasts week's form to add new resources.

Kidney=nephrons=unfiltered blood in through artery(go through top of nephron), blood goes through glomerulus, then through tubes=water and nutrients absorbed= back to blood and body through veins(go through botton of nephron), waste=out of nephron through collecting duct

the kidney pushes blood through a screen like thing that will serperate the toxins from the blood.

so if we don't get a tide on the opposite side of the Earth from the moon by leaving water behind how does it happen?

What do vestigal organs do?

Myles said...

Are there any dieses that affect the kidney?

John said...

Myles,

Better to ask, "What did they do?"

Kate Sommerfeld said...

Myles, I did some research and apperenly its an organ that was once useful in an animals evolutionary past, but is now close to useless in humans. Evolutionary is a gradual process in which something changes into a different or usually more complex and better form. But whatever they did, it must not be important anymore otherwise we would have them in our bodies, right?

Red blood cells are in a liquid called plasma, which is 55% of blood fluid, is mostly water, and contains disolved protiens,glucose, iron, hormones, carbon dioxide, and platelets.
