Transcript Amphibians vs. Mammals

Amphibians
Frogs
Anatomy Vocabulary
• Body Systems – Digestive System,
Nervous System, Circulatory System,
Excretory System, Muscular System,
Skeletal System, Respiratory System
• Cloaca – one hole for solid waste, liquid
waste, and reproduction.
• Liver – organ that removes toxins from
blood, and dissolves fats
• Pancreas – organ that makes digestive
enzymes and hormones.
Amphibians
• Amphibians have advanced, complex
body systems.
STERNGRR
• What do animals synthesize?
• Proteins, Lipids, Nucleic
• Acids,
• Large Carbohydrates
STERNGRR
• What do frogs need to transport around
their bodies?
• How do frogs transport things around their
bodies?
• Oxygen, CO2, nutrients
Closed Circulatory
System
• Frogs have a three
chambered heart.
• Arteries bring blood
from the heart.
• Veins bring blood to
the heart.
• Oxygenated blood
mixes with
Deoxygenated blood.
STERNGRR
• What do frogs need to excrete from their
bodies?
•
•
•
•
•
CO2
Nitrogen
Water
Salts
Solid waste
Excretory System
• Frogs have two kidneys.
• Each one filters the blood and passes
urine to the bladder.
• The bladder empties into the cloaca.
• Why would the frog need two kidneys?

What kind of respiration do frogs do?
Aerobic Cellular Respiration
What kind of gas goes in?
Oxygen
What kind of gas goes out?
Carbon Dioxide
Respiratory System
• Frogs have a lung and a tongue that
pushes air in.
• They also breath through their moist skin
by diffusion. It has to be moist.
• Why is it an advantage to have two
methods of respiration?

Frogs are heterotrophs (consumers).
Where do frogs get their nutrients?
Eat insects
What is the name for an organism that
only eats heterotrophs?
• Carnivores
Digestive System
• Tongue, throat, stomach (churning and
digesting), small intestine (digesting and
absorbing), large intestine (absorbing water solid
waste storage).
• Liver, gall bladder – puts bile into stomach.
• Pancreas – puts digestive enzymes into
intestine.
• Villi – small finger like projections in the small
intestine that allow for greater absorption of
nutrients.
• Large intestine empties solid waste from the
cloaca.
STERNGRR
• Amphibians develop from a
tadpole with a tail and external gills
to an
adult with no tail, 4 limbs, and internal lungs
• Amphibians need water for their eggs and
tadpole stage. They tend to live near water
as adults.
STERNGRR
• Frogs are ectotherms or cold blooded.
They have to be in the correct
environment to maintain homeostasis.
What must do?
• Move
Muscular Skeletal System
• Frogs have muscles
and bones that work
together for movement.
• Muscles don’t push.
• Two work in opposite
directions.
• Joints and ligaments
connect bones.
• Tendons connect
muscle to bone.
STERNGRR
• How do they control their movement and
other internal regulations?
• How do they sense their environment?
• Nervous system
• Five sences .
Nervous System
•

•
Frogs have a brain.
Frogs are chordates so they have what?
Spinal cord
Frogs are vertebrates so they have what?
Vertebrate bones
Around the spine
STERNGRR
• Where do frogs reproduce? Where do the
females lay her eggs?
• Water.
Reproductive System
• Frogs are male (with testicles) or female (with
ovaries). What type of cell division is done in
the gonads?
• Frogs do sexual reproduction
• Males attract a mate by making throat sounds.
• Females tend to be larger.
• Frogs do external fertilization.
• Frogs have soft eggs that need to be in water.
• Tadpoles hatch from the eggs.
