Nervous, Endocrine, And Respiratory Systems

Front 1

feedback loop

Back 1

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

Front 2

insulin

Back 2

hormone that is produced by the pancreas that works to maintain the level of sugar in the blood

Front 3

glucagon

Back 3

hormone produced by the pancreas that signals liver cells to convert glycogen to glucose and release glucose into the blood

Front 4

adrenaline

Back 4

hormone that is released under times of stress

Front 5

thyroxin

Back 5

regulates body temperature

Front 6

diagram a body and label the
-thyroid
-adrenal
-pituitary
-pancreas

Back 6

(see attached paper)

Front 7

what is the difference between type one and type two diabetes

Back 7

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.

Front 8

what is the function of the respiratory system?

Back 8

brings oxygen into body and releases carbon dioxide from the body (gas exchange)

Front 9

what is alveoli?

Back 9

looks like little balloons, site of gas exchange in lungs

Front 10

tidal volume

Back 10

the normal amount of air that moves in and out of the lungs

Front 11

vital capacity

Back 11

the maximum amount of air that moves in and out of the lungs

Front 12

cystic fibrosis

Back 12

genetic disorder when the mucus in the lungs becomes very thick and it is difficult to breath

Front 13

diagram and label a neuron. give the definition of a dendrite, axon, and synapse

Back 13

(diagram of neuron attached)

Front 14

dendrite

Back 14

receive neurotransmitters

Front 15

axon

Back 15

sends information to next neuron

Front 16

synapse

Back 16

space between 2 neurons for neurotransmitters to travel across

Front 17

function of nervous system

Back 17

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

Front 18

structure of nervous system

Back 18

1. central nervous system
-brain and spinal cord
2. peripheral nervous system
-all neurons
-sensory and motor (senses and muscle movement

Front 19

cerebrum

Back 19

-largest part of brain
-responsible for higher levels of though and actions
-4 lobes (frontal, parietal, temporal, and occipital

Front 20

functions of frontal lobe

Back 20

-reasoning
-planning
-movement
-logic
-emotions
-speech

Front 21

functions of temporal lobe

Back 21

-hearing
-speech
-memory

Front 22

functions for parietal lobe

Back 22

-movement
-recognition

Front 23

function for occipital lobe

Back 23

-vision

Front 24

hormones

Back 24

chemicals that regulate how the body responds to stimuli

Front 25

examples of hormones and functions

Back 25

-testosterone-masculization, builds muscles
-estrogen-feminization, ovulation
-thyroxin-regulates body temperature

Front 26

how do hormones travel

Back 26

hormones travel through blood which means that the body has a slower response than the nervous system

Front 27

function of hormones

Back 27

maintains homeostasis in the body

Front 28

how does the feedback loop work?

Back 28

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

Front 29

what are structures of the respiratory system?

Back 29

nose, trachea, bronchi, lungs, and alveoli

Front 30

what part of the body controls the breathing?

Back 30

the brain

Front 31

how does breathing occur?

Back 31

nerves cause the diaphragm to contract which increases volume in the lungs so they can expand

Front 32

what happens when you exhale?

Back 32

diaphragm relaxes, decreases volume in lungs and air moves out

Front 33

what are two facts about asthma?

Back 33

-cuts off air to lungs
-no cure, but prevention medications such as an inhaler

Front 34

what are two facts about muscular dystrophy?

Back 34

-it is genetic
-it is fatal
-there is no cure

Front 35

what is one fact about lymphoma?

Back 35

-preferred treatment is radiotherapy

Front 36

neurons

Back 36

-communicate information throughout the body
-sends information through neurotransmitters
