Anatomy Vocabulary Body SystemsBody Systems – Digestive System, Nervous System, Circulatory System, Excretory System, Muscular System, Skeletal System, Respiratory System CloacaCloaca – one hole for solid waste, liquid waste, and reproduction. LiverLiver – organ that removes toxins from blood, and dissolves fats PancreasPancreas – organ that makes digestive enzymes and hormones.

Amphibians Amphibians have advanced, complex body systems.

S TERNGRR What do animals synthesize? Proteins, Lipids, Nucleic Acids, Large Carbohydrates

S T ERNGRR What do frogs need to transport around their bodies? How do frogs transport things around their bodies? Oxygen, CO 2, nutrients

Closed Circulatory System Frogs have a three chambered heart. ArteriesArteries bring blood from the heart. VeinsVeins bring blood to the heart. Oxygenated blood mixes with Deoxygenated blood.

ST E RNGRR What do frogs need to excrete from their bodies? CO 2 Nitrogen Water Salts Solid waste

Excretory System Frogs have two kidneys. Each one filters the blood and passes urine to the bladder. cloacaThe bladder empties into the cloaca. Why would the frog need two kidneys?

STE R NGRR 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?

STER N GRR 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 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. cloacaLarge intestine empties solid waste from the cloaca.

STERN G RR Amphibians develop from a tadpole tadpole with a tail and external gills to an adult 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.

STERNG R R ectothermsFrogs 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. JointsligamentsJoints and ligaments connect bones. TendonsTendons connect muscle to bone.

STERNG R R 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

STERNGR R 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.

STERN G RR Mammals develop inside the womb. Mammals go through puberty to become sexually mature. What type of cell division allows multicellular organisms to grow into adults?

STERNG R R endothermsFrogs are endotherms or warm blooded. They can regulate their own internal environment to maintain homeostasis? How can endotherms become warm? Shiver, increase metabolism How can endotherms cool off? Sweat.

Metabolism What is made during cellular respiration? ATP When energy is used moving muscles what is created? Heat What other adaptation keeps mammals warm? fur

Sweat What do mammals do to keep from getting too hot? Sweat

STERNGR R Where do pigs reproduce? On land. Do pigs give live birth or have eggs? Live What do pigs and all mammals have for their young to drink? milk

Mammary Glands Glands under the skin produce milk.

Reproductive System Pigs are male (with testicles) or female (with ovaries). What type of cell division is done in the gonads? Pigs do sexual reproduction. Wild pigs fight for females with tusks. Pigs do internal fertilization. Pigs have live birth. Pigs have a placenta for the growing fetus. Pigs have milk for their young.
