Frog Packet
Our unit built on their learning about biomes. Many plants
and animals depend on aquatic biomes. Amphibians are the
vertebrate class that best bridges the biomes of land and
water. Using our ecology workbooks, our green text book,
youtube videos, and chromebook research, we learned about
the frog and its amazing adaptation for life on land and in the
water.

Draw the heart. Label the atria and ventricle. What do the atria do? What does
the ventricle do?

Spleen
The spleen is involved in destruction of old or damaged red blood cells.
It stores blood. The spleen can release its stored blood to replace
blood lost during a traumatic injury. Many platelets are also stored
with the blood in the spleen to help form blood clots to prevent further
blood loss. The spleen produces specialized white blood cells called
lymphocytes and antibodies. An antibody is a large Y-shaped protein
used by the immune system to identify and neutralize foreign objects
such as bacteria and viruses.
The working spaces of the spleen can be divided into the white pulp
and the red pulp. The white pulp destroys pathogens in the blood and
produces antibodies. The red pulp is awash in blood and filled with
macrophages that cleanse the blood of pathogens, especially bacteria,
and dead red blood cells. Between the red and white pulp, the layers
act as a filter to capture pathogens in the blood and pass these
pathogens on to the white pulp.
For biologist and herpetologist Tyrone Hayes, scientific breakthroughs don't
begin and end in the laboratory. They also come from the field. Which is why,
more often than not, you'll find Hayes wet, muddy, and knee-deep in a swamp at
2 a.m., the time when the frogs come out.
Dr. Hayes grew up in South Carolina, and, as a boy, one of his favorite pastimes
was tracking down the region's abundant turtles, snakes, and toads. That abiding
fascination led Hayes to earn an undergraduate degree in biology from Harvard
University. He later received a Ph.D. from the University of California,
Berkeley, where he currently serves as a professor.
