Bio Cycle Test Flashcards
Balanced diet
Containing adequate amounts of necessary nutrients of all food groups for healthy growth.
Solvent
Liquid in which substances are dissolved to form a solution.
Malnutrition
Condition resulting from the lack of nutrients required for growth
Obesity
Having an excessive amount of body fat
Constipation
Bowel movements occur less frequently
Consists of hard and dry stool
Ulcers
Sores in the lining of mouth and intestines
Additives
Chemical substances that makes food last longer
Digestion
The breakdown of food into a form that can be absorbed by body
Peristalsis
Rhythmic contraction of muscle layers in digestive canal that push the food forward
Enzymes
Proteins that speed up the rate of chemical reaction.
Mechanical digestion
Physical breakdown of food by crushing/chewing
Chemical digestion
Breakdown of food into nutrients through chemical reactions.
Stimulus
change in environment which cause a reaction in living organisms.
Receptors
Cells in sense organs which detect stimuli from the environment.
Impulses
Electrical signals transmitting along nerves
Nerve cell
Cells that receive and send impulses from the body to the brain and back
Spinal Cord
Nerve tissue that extends from the brain, through spinal column, in which nerve cells carry information from body to the brain and back to the body
Spinal Cord
Nerve tissue that extends from the brain, through spinal column, in which nerve cells carry information from body to the brain and back to the body
Effectors
Organs that respond to stimuli (muscles of glands)
What functions enable survival
Sensing
Responding
Interpreting
What is the sensory neuron
Transmits nerve impulses from the receptor to the brain or spinal cord
What is a motor neuron
Transmit nerves impulses from brain or spinal cord to the effector
