FANTASTIC FROGS!
From the outside in!

External Anatomy of the Frog

• Observe the exterior of the frog as shown in the
  picture.
• Identify the tissue type that makes up the frogs
  skin. Use prior knowledge to support your
  response.

Internal Organs of the Frog (Layer 1)

Internal Organs of the Frog (Layer 2)
stomach
intestines

• Label the spleen, stomach, intestines, and
  kidneys on Figure 2.

5
Internal Organs of the Frog (Layer 2 continued)

• Locate the structure numbered 42 on the diagram.
  This structure is one of the frogs lungs.
• Observe the position of the lungs in relation to
  the heart.
• Explain the benefits of having the heart and
  lungs positioned as they are. Use prior
  knowledge to support your response.

6
Internal Structure of a Frog Heart

• Identify and label the right atrium, left atrium,
  and the ventricle on Figure 3.
• Compare the complexity of the frogs heart to the
  heart of a white perch. Use evidence from this
  investigation and prior knowledge to support your
  response.

In this view of the model frog heart,  the front
of the heart has been removed to reveal the
arrangement of the three chambers (2 atria and 1
ventricle).

Internal Anatomy of the Frog A Comparison

• Study the picture showing the internal organs of
  a frog.
• Compare the complexity of a frogs anatomy to the
  perchs anatomy. Use evidence from the
  investigation and prior knowledge to support your
  response.

• Heart (ventricle) 7. Large Intestine
• Lung 8. Kidney
• Spleen 9. Urinary Bladder
• Liver 10. Oviduct
• Stomach 11. Fat Bodies
• Small intestine

Internal Anatomy of a Pig

• Observe the internal structures of the pig.
• Identify and label the heart, lung, and diaphragm
  on Figure 4.

10
External Structure of a Pig Heart

• Observe the picture of the pig heart.
• Identify the type(s) of tissue(s) that work
  together to enable the pigs heart to pump blood.
  Use prior knowledge to support your response.

11

• Label the chambers of the heart on the diagram in
  Figure 5.
• Compare the complexity of a pigs heart to the
  heart of a frog, and the heart of a white perch.
  You may construct a graphic organizer, a diagram,
  or respond in complete sentences.Use evidence
  from this investigation and prior knowledge to
  support your answer.

Internal Structure of the Pig Heart
12
Circulatory and Excretory Systems of the Pig

• Observe the positions of the heart, a major blood
  vessel, and the kidneys in the pig.
• Explain how the circulatory system and the
  excretory system interact within the pig. Use
  evidence from the investigation and prior
  knowledge to support your response.

heart
Blood vessel
kidneys
13
Anatomy of a Pig A comparison

• Observe the organs and organ systems of the pig.
• Compare the complexity of a pigs anatomy to the
  anatomy of the frog and the white perch. Use
  evidence from the investigation and prior
  knowledge to support your response.

14
So what does this mean to me??
Many people believe that humans are
scientifically unlike other animals on Earth.
Explain why this belief is not accurate. Use
evidence from this investigation and prior
knowledge to support your response.
The End!!!
