Homeostasis
The body's internal environment remains constant despite changes in the external environment
1 of 23
Negative Feedback Mechanism
1.Receptors detect change 2. Message sent 3.Response initiated 4 Body returns to normal state
2 of 23
Blood sugar
Pancreas secretes INSULIN and GLYCOGEN to control glucose levels
3 of 23
Body temperature 37* (temp that enzymes work best)
Controlled by sweating/shivering
4 of 23
Water Content (to protect cells)
lungs, skin, kidneys
5 of 23
Salt and water balance
Kidneys
6 of 23
Carbon Dioxide level
lungs
7 of 23
Oxygen to the cells
Respiratory and circulatory systems
8 of 23
Hormones
chemicals secreted by glands
9 of 23
Endocrine glands
Organs that produce hormones

Central Nervous System
Brain and Spinal Cord
11 of 23
Peripheral Nervous System
made up of sensory and motor neurons all over your body
12 of 23
Neuron
A nerve cell
13 of 23
Nerve
A bundle of neurons
14 of 23
Sensory neuron
A nerve cell that detects changes in the environment and send message to Central Nervous System
15 of 23
Motor neuron
nerve cell that causes muscle or gland to respond to stimulus
16 of 23
Interneuron
Link between sensory neurons and motor neurons
17 of 23
Effectors
muscles or glands that respond to a stimulus
18 of 23
Neurotransmitter
Chemical released to conduct impulse across synapse
19 of 23
Respiration
Glucose +Oxygen =CO2 +water+energy
20 of 23
Waste products of respiration
CO2 + nitrogenous waste
21 of 23
Nitrogenous waste (Protein Metabolism)
Liver -> Urea -> Kidneys ->Urine

Enzymes
Proteins that regulate chemical reactions in the body
