feedback loop
|
communicates with the brain to help maintain homeostasis
-example:if the body needs insulin, the brain will send a message to the feedback loop and the feedback loop will make sure insulin is then released |
|
insulin
|
hormone that is produced by the pancreas that works to maintain the level of sugar in the blood
|
|
glucagon
|
hormone produced by the pancreas that signals liver cells to convert glycogen to glucose and release glucose into the blood
|
|
adrenaline
|
hormone that is released under times of stress
|
|
thyroxin
|
regulates body temperature
|
|
diagram a body and label the
-thyroid -adrenal -pituitary -pancreas |
(see attached paper)
|
|
what is the difference between type one and type two diabetes
|
type one diabetes means that there is no insulin in the body and type two diabetes means that the body has insulin, but is resistant to it.
|
|
what is the function of the respiratory system?
|
brings oxygen into body and releases carbon dioxide from the body (gas exchange)
|
|
what is alveoli?
|
looks like little balloons, site of gas exchange in lungs
|
|
tidal volume
|
the normal amount of air that moves in and out of the lungs
|
|
vital capacity
|
the maximum amount of air that moves in and out of the lungs
|
|
cystic fibrosis
|
genetic disorder when the mucus in the lungs becomes very thick and it is difficult to breath
|
|
diagram and label a neuron. give the definition of a dendrite, axon, and synapse
|
(diagram of neuron attached)
|
|
dendrite
|
receive neurotransmitters
|
|
axon
|
sends information to next neuron
|
|
synapse
|
space between 2 neurons for neurotransmitters to travel across
|
|
function of nervous system
|
1. receive information and respond to it - includes all sensory processing
2. maintains homeostasis by sensing imbalances and signaling for correction -example: brain senses drop in body temperature, so the brain signals for hormones to raise temperature |
|
structure of nervous system
|
1. central nervous system
-brain and spinal cord 2. peripheral nervous system -all neurons -sensory and motor (senses and muscle movement |
|
cerebrum
|
-largest part of brain
-responsible for higher levels of though and actions -4 lobes (frontal, parietal, temporal, and occipital |
|
functions of frontal lobe
|
-reasoning
-planning -movement -logic -emotions -speech |
|
functions of temporal lobe
|
-hearing
-speech -memory |
|
functions for parietal lobe
|
-movement
-recognition |
|
function for occipital lobe
|
-vision
|
|
hormones
|
chemicals that regulate how the body responds to stimuli
|
|
examples of hormones and functions
|
-testosterone-masculization, builds muscles
-estrogen-feminization, ovulation -thyroxin-regulates body temperature |
|
how do hormones travel
|
hormones travel through blood which means that the body has a slower response than the nervous system
|
|
function of hormones
|
maintains homeostasis in the body
|
|
how does the feedback loop work?
|
1. brain determines amount of hormones in blood
2. brain signals endocrine system to adjust the amount of hormones based on body's need so homeostasis can be maintained |
|
what are structures of the respiratory system?
|
nose, trachea, bronchi, lungs, and alveoli
|
|
what part of the body controls the breathing?
|
the brain
|
|
how does breathing occur?
|
nerves cause the diaphragm to contract which increases volume in the lungs so they can expand
|
|
what happens when you exhale?
|
diaphragm relaxes, decreases volume in lungs and air moves out
|
|
what are two facts about asthma?
|
-cuts off air to lungs
-no cure, but prevention medications such as an inhaler |
|
what are two facts about muscular dystrophy?
|
-it is genetic
-it is fatal -there is no cure |
|
what is one fact about lymphoma?
|
-preferred treatment is radiotherapy
|
|
neurons
|
-communicate information throughout the body
-sends information through neurotransmitters |
