A new year, a new system!

Today we started on the circulatory system by taking a brief reading quiz. Based on this, you should review your notes from you textbook and add any additional ideas/thoughts you missed.  We started a list of organs and tissues involved in the circulatory system:

Blood (RBC, WBC, Plasma)
Heart (Ventricles, Atria (Plural for Atrium))
      Left Ventricle - most muscular, under high pressure, pumps blood to rest of body, largest chamber
      Right Atrium - smallest, less muscular, under low pressure
      we will discuss the others as we move on
Veins - carry blood to the heart! have valves so blood doesn't flow backwards, thinner and less muscular
Venuoles - small veins
Arteries - carry blood away from the heart, thick and muscular, no valves, under high pressure
Arterioles - small arteries
Capillaries -where gas exchange occurs

Homework for tonight: Read entire lab and answer questions on pages 1-5. Below is also a video about Blood Pressure
