LO5 Flashcards
what are the components of the kidney
cortex
medulla
renal artery
renal vein
calyx
ureters
bladder
urethra
what is the function of the cortex
it is the outer layer of the kidney
what is the function of the medulla
the inner region that contains thousands of nephrons
what is the function of the renal artery
supplies the kidneys with blood
what is the function of the renal vein
carries the blood filtered by the kidneys
what is the function of the calyx
chambers through which urine passes
what is the function of the ureters
tubes that carry the urine from the kidney to the bladder
what is the function of the bladder
stores urine
what is the function of the urethra
urine passes out of the body through this
what are the two main functions of the kidney
-removal of urea
-maintenance of the balance of the water levels (osmoregulation)
how do the kidneys carry osmoregulation
controlling the water concentration in the blood plasma
what do the kidneys control not including water
salt levels and excretion of urea
what is ultrafiltration
metabolic waste is separated from the blood and urine is formed
occurs in the glomerular capsule in the nephron
what happens after filtration in the kidneys
kidneys selectively reabsorb molecules that the body needs
happens in the proximal and distal tubules and the water is reabsorbed in the loop of henle
what are the components of the nervous system
central nervous system
spinal cord
autonomic system
sensory and motor neurons (somatic system)
peripheral nervous system
what is the structure and function of the cerebral cortex
wrinkly, outermost layer of the brain, responsible for thinking and processing of the sensory information of the body. there are four lobes, each responsible for processing different types of information. it is made of tightly packed neuron.
what is the structure and function of the cerebellum
positioned at the back of the skull, co-ordination and regulation muscle activity. involved in the control of muscle to maintain balance
what is the structure and function of the frontal lobe
carry out higher level mental process such s thinking.
what is the structure and function of the corpus callosum
bridge of nerve tissue that connects two halves of the brain and enables communication between the 2.
what is the structure and function of the hypothalamus
responsible for the maintenance of body temperature. regulates appetite and thirst
what is the structure and function of the medulla
automatically carries out and regulates life-sustaining functions such as breathing ect
what is the structure and function of the meninges
three layers of membranes surrounding the brain and spinal cord. provide barrier to infection
what are the components of the neuron
neuron
axon
dendron
myelin sheath
structure and function of the neuron
specialized nerve cells that transmit electrical impulses from one part of the body to another
structure and function of the axon
long thread like part of the nerve cells along which impulses are conducted
