Internal Anatomy of a Frog Flashcards
Sac which stores bile
Gall bladder
The anterior (front) part of the small intestine into which food passes from the stomach
Duodenum
Stores food and mixes it with enzymes to begin digestion.
Stomach
The principal organ of digestion and absorption of digested food.
Small intestine
Gland which secretes digestive enzymes into the duodenum.
Pancreas
Posterior organ of the digestive system which stores undigested food.
Large instestine
Organ through which the products of the frogs digestive and urogenital system pass when discharged from the body.
Cloaca
Secretes bile and processes digested food molecules
Liver
The liver of a frog has ____ lobes.
three / 3
Masses of fat in the body cavities of frogs. Needed for hibernating and mating
Fat bodies
The organ that collects and stores urine until released.
Urinary bladder
Organ in the frog’s circulatory system that makes, stores, and destroys blood cells.
Spleen
Pumping organ of the circulatory system (has 3 chambers).
Heart
Sac that receives blood from the vena cava
Sinus venosus
Large vein that carries blood from the posterior part of the body towards the heart.
Posterior vena cava
Large vein that carries blood from the anterior part of the body toward the heart.
Anterior vena cava
Large artery in a frog that carries blood away from the ventricle into branches that lead to all parts of the body.
Truncus Arteriosis
Cushions and encloses the heart
Pericardium
Chamber of a frog’s heart that pumps blood out of the heart to the lungs and other parts of the body.
Ventricle
Chamber of the frogs heart which receives blood from the sinus venosus.
Right atrium
The chamber of the heart that receives blood from the lungs.
Left atrium
The blood vessels that carry blood form the lungs to the left atrium.
Pulmonary veins
filter the blood and excretes excess water.
kidneys
carry the urine from the kidneys to the urinary bladder.
ureter
three functions of fat bodies in a frog
hibernating, metamorphosis and mating
contains the stored energy of a frog
Fat bodies
Female sex cell or gametes
Ova or eggs
Tubes in a frog that carry urine from the kidneys to the cloaca
Urinary ducts
The organ that collects and stores urine until released.
Urinary bladder
Organs located near the kidneys which secrete hormones.
adrenal glands
Male sex cell or gametes.
Sperm
Organs of the female reproductive system that produce the eggs.
Ovaries
Tubes of a female frog’s reproductive system that carry eggs from the ovaries to the cloaca.
Oviducts
Male reproductive organ that produces sperm
testes
Enlarged distal sections of the male frog’s urinary ducts that collect sperm prior to entry into the cloaca.
Seminal vesicles
Nerves that lead to and from the brain.
Cranial Nerves
Part of a brain that is the center for some involuntary functions.
Medulla Oblongata
Part of a brain that influences balance and equilibrium.
Cerebellum
Main pathway to and from the brain
Spinal Cord
Part of the frog’s brain associated with the sense of smell
Olfactory Lobe
Nerves that lead to and from the spinal cord
Spinal Nerves
Part of the brain that is associated with memory, pain, and voluntary muscle control.
Cerebrum
Part of the brain associated with vision.
Optic lobes
