This vessel carries blood from the intestine to the liver.
Hepatic portal vein
This vessel is the main route of blood from the tail, pelvic appendages, and kidney in lungfishes and tetrapods.
Postcava
This system transports blood returning from capillary beds within the tail or hindlimbs through the kidneys to the cardinal system.
Renal portal system
This vessel empties into capillary beds within the kidneys.
Renal Portal Vein
This vessel is the major vein that receives blood returning from the posterior and anterior cardinal veins.
Common cardinal vein
This vessels drains the anterior portion of the body, head and neck
Anterior cardinal vein
This vessel drains the posterior portion of the body.
Posterior cardinal vein
This set of veins arise from the ventral side of kidneys, drains and runs forward, and empties into posterior cardinals.
Subcardinal vein
Veins from the lateral body wall and posterior appendages empties into the common cardinal vein via the ________ __________ _______.
Lateral abdominal vein
In amphibians, the left and right lateral abdominal veins empty into this single median vein which runs along the floor of the body coelom.
Ventral abdominal vein
This vein drains the head of fishes and joings the common cardinal vein.
Inferior Jugular Vein
This vein is derived from the anterior cardinal vein and drains the blood from the head. Its origin is in amphibians.
Internal jugular vein
This vein drains the blood from the head and lies outside the internal jugular vein.
External jugular vein
This part of the kidney consists of the glomerulus, renal capsule, and collecting tubule.
Nephron
This is derived from mesoderm and consists of nephrotomes and nephric ridge.
Mesomere
The anterior segmented region of the mesomere is the _______.
Nephrotomes
The posterior not segmented region of the mesomere is the _____________.
Nephric ridge
This region of the kidney is a ball of capillaries with high pressure arterial vessels at both ends.
Glomerulus
This portion of the nephron collects filtrate.
Renal capsule (Bowman's capsule)
This portion of the nephron has regional differentiation and selective absorption and secretion occurs here.
Renal tubule
In mammals, this portion of the nephron contains the loop of henle.
Renal tubule
The nephon empties into this portion of the kidney.
Collecting duct
A kidney formed of nephric tubules arising in the anterior region of the nephric ridge is called a _____________.
Pronephros
This kidney usually forms only as a transient embyro structure.
Pronephros
This kidney if formed of nephric tubules arising in the middle of the nephric ridge.
Mesonephos
This kidney is usually a transient embryonic stage that replaces the pronophros.
Mesonephros
This kidney is formed of nephric tubules arising in the posterior region of the nephric ridge and drained by a ureter.
Metanephros
This kidney usually replaces the embyronic pronephros and mesonephros.
Metanephros
The proneohros gives rise to theis duct that induces development of posterior tubules.
Pronephric duct
This is the name of the adult kidney formed from the mesonephros and additional tubules from the posterior region of the nephric ridge.
Opisthonephros
This is the metanephric duct arising as a uteteric diverticulum and draining the metanephros.
Ureter
This type of gonads are indifferent in early developent.
Indifferent gonad
This area of the gonad is a looser array of cells adjacent to coelomic epithelium
Cortex of indifferent gonad
This area of the indifferent gonad arises from germinal epithelium and regresses in females and enlarges in males.
Cortex of indifferent gland
This region of the indifferent gonad has compact cells adjacent to the kidney.
Medulla of indifferent gland
This region of the indifferent gonad arises from the blastema and regresses in males and enlarges in females.
Medulla of indifferent gland
The female gonads are the ____.
Ovaries
The male gonads are the _____.
Testis
A _____ transmits waves of depolarization (action potentials). = information transfer
Neuron
This is the 'neural glue' that supports and electrically insulates neurons.
Neuroglia
A nerve fiber of a neuron that carries an impulse away from the cell body is called a ________.
Axon
A nerve fiber of a neuron that carries impulses toward the cell body is called a ______.
Dendrite
The region of contact between two neurons or between a neuron and an effector organ is called a _______.
Synapse
A neuron cell that has many projections from the cell body is called __________.
Multipolar
A neuron cell that has one axon segment projecting from the cell body is called _______.
Unipolar
A neuron cell that has two axon segments projecting from the cell body is called ________.
Bipolar
This pathway consists of sense organs in the skin, tendons of skeletal muscle, and skeletal muscle.
Somatic information pathway
This pathway consists of sense organs in walls of viscera such as strength receptors.
Visceral information pathway
This pathway carries information from parts of the body to the brain.

This pathway carries information from the brain to parts of the body.
