AmphibiansAmphibians• Amphibians have advanced, complex

body systems.

SSTERNGRRTERNGRR• What do animals synthesize?

• Proteins, Lipids, Nucleic

• Acids,

• Large Carbohydrates

SSTTERNGRRERNGRR• What do frogs need to transport around

their bodies?

• How do frogs transport things around their bodies?

• Oxygen, CO2, nutrients

Closed Circulatory Closed Circulatory SystemSystem

• Frogs have a three chambered heart.

• ArteriesArteries bring blood from the heart.

• VeinsVeins bring blood to the heart.

• Oxygenated blood mixes with Deoxygenated blood.

STSTEERNGRRRNGRR• What do frogs need to excrete from their

bodies?

• CO2

• Nitrogen• Water• Salts• Solid waste

Excretory SystemExcretory System• Frogs have two kidneys.

• Each one filters the blood and passes urine to the bladder.

• The bladder empties into the cloacacloaca.

• Why would the frog need two kidneys?

STESTERRNGRRNGRR• 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 SystemRespiratory 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?

STERSTERNNGRRGRR• 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 SystemDigestive System• Tongue, throat, stomach (churning and

digesting), small intestine (digesting and absorbing), large intestine (absorbing water solid waste storage).

• Liver, gall bladderLiver, gall bladder – puts bile into stomach.• PancreasPancreas – puts digestive enzymes into

intestine.• VilliVilli – small finger like projections in the small

intestine that allow for greater absorption of nutrients.

• Large intestine empties solid waste from the cloacacloaca.

STERNSTERNGGRRRR• Amphibians develop from a

tadpoletadpole with a tail and external gills

to an

adultadult 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.

STERNGSTERNGRRRR• Frogs are ectothermsectotherms or cold blooded.

They have to be in the correct environment to maintain homeostasis. What must do?

• Move

Muscular Skeletal SystemMuscular Skeletal System

• Frogs have muscles and bones that work together for movement.

• Muscles don’t push.• Two work in opposite

directions.• JointsJoints and ligamentsligaments

connect bones.• TendonsTendons connect

muscle to bone.

STERNGSTERNGRRRR• How do they control their movement and

other internal regulations?

• How do they sense their environment?

• Nervous system

• Five sences .

Nervous SystemNervous 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

STERNGRSTERNGRRR• Where do frogs reproduce? Where do the

females lay her eggs?

• Water.

Reproductive SystemReproductive 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.
