The document summarizes the main body systems of frogs: - The reproductive system allows frogs to produce offspring through external fertilization, with males releasing sperm onto eggs laid by females. - The endocrine system secretes hormones to regulate processes like hibernation and reproduction. - Other body systems discussed include the nervous, muscular, skeletal, circulatory, respiratory, excretory, integumentary and digestive systems, which perform similar functions to humans.

1. Functions of
the Frogs
Body
Systems

2. • The reproductive system of the frog is to create
offspring to continue the species.
• Male frog has testes that release sperm on top of
females eggs for fertilization.
• Female frog has ovaries that produce eggs. Females
lay eggs on the ground, then the male will lay his
sperm on top of the eggs for fertilization.
When dissecting, the sex of the frog is the last fact you
will discover because the reproductive organs are
located along the spine of the frog. If your female
frog has eggs forming, you can see these upon
cutting the frog open.
The Reproductive System

3. • The endocrine system in frogs
help with hibernation and
reproduction.
• Hormones are secreted by various
endocrine glands to maintain
homeostasis within the frog.
The Endocrine System

4. The Nervous System
• The nervous system in frogs is highly
developed. It consists of a brain, a
spinal cord, and nerves.
• It aids the frog in all of its senses to
respond to internal and external
stimuli.

5. The Muscular System
• The muscular system in frogs performs
similar functions as humans.
• Movement of the body.
• Movement of material within the body.
• Frogs main muscular action is large leg
muscles for jumping.

6. The Skeletal System
• The skeletal system in frogs
performs similar functions as
humans.
• Points of muscle attachment.
• Joints connect bones to be levers
for movement.
• Marrow produces blood cells.

7. The Circulatory System
• The circulatory system in frogs
performs similar functions as humans,
but the structure is somewhat
different.
• The frog’s heart has 3 chambers.
• Oxygenated and deoxygenated blood
mix in the heart.
• Arteries and veins carry blood
containing nutrients, wastes and
hormones throughout the body.

8. The Respiratory System
• The respiratory system in frogs is unique
in that the lungs aren’t the only organ
that exchanges oxygen and carbon
dioxide.
• The frog’s skin is also used to exchange
gasses when submerged in water.
• Lungs are used to exchange O2 & CO2
between the atmosphere and body.

9. The Excretory System
• The excretory system in frogs
includes the urinary system along
with respiratory, digestive and
integumentary systems, same as
humans.
• The kidney’s, ureters, bladder and
cloaca make up the urinary system.
• Liquid wastes are filtered from the
blood and stored as urine.

10. The Integumentary System
• The integumentary system in frogs
has several functions that are needed
for survival.
• Protection through camouflage.
• Permeable skin to breathe through.
• Stays moist for protection against
injury and infection.

11. The Digestive System
• The digestive system in frogs is similar to
humans. We have most structures in
common.
• Digest food mechanically and chemically.
• Food is broken down to create energy
for all body functions.
• Solid wastes are created and excreted
via the cloaca.
