Mitochondria
Cytoplasm
Chloroplast
What is the function of the digestive system?
It transports blood and oxygen to your cells
It breaks down food so the nutrients can be absorbed by your body
It helps you breathe by taking in oxygen and transporting carbon dioxide out of your body
It helps you move
What is the function of the muscular system?
The function is movement of the body through muscles
The function is to get rid of waste
The function is to process food for nutrients and energy
The function is to protect you against disease
What is the function of the cardiovascular / circulatory system?
To provide nutrients to the whole body
To maintain homeostasis for the body
To fight off infection or disease
To transport nutrients, oxygen, and blood throughout the body
What is the function of the nervous system?
Controls all parts of the body; sends signals between the brain, spinal cord, and nerve endings
What happens when you get nervous to do something
To fight off diseases
To carry oxygen, nutrients, and blood throughout the body
What is the function of the respiratory system?
To digest your food
To remove waste from the body
To take in oxygen and remove carbon dioxide
To fight disease
What is the function of the excretory/urinary system?
Removes liquid waste from your body
digests food
helps you breathe
circulates your blood
The steel beams that hold up a tall building are most analogous (similar) to which body system?
skeletal
muscular
digestive
immune
What is the function of the skeletal system?
Movement of the body
transports oxygen, blood, nutrients throughout the body
removes waste
supports the body by holding it up; muscles are attached to help with movement
How do the body systems work together when you accidentally touch a hot pan?
The cardiovascular/circulatory system sends signals to your hand to move it, and your nervous system moves your hand
The nervous system (brain, spinal cord, and nerves) send a signal to your hand to move it, and your muscular system causes your hand to move
The digestive system moves your hand, and the cardiovascular/circulatory system sends signals to your hand
The nervous system causes your hand to move, and the muscular system breaks down nutrients for your muscles to move
The passing of genetic material from parents to offspring.
heredity
gene
allele
genotype
phenotype
Segments of DNA (Deoxyribonucleic acid) found in chromosomes that give instructions for producing a certain characteristic.
heredity
gene
allele
genotype
phenotype
Why is heredity important?
It keeps organisms in their species.
It makes the DNA inside cells similar.
It passes traits from parents to offspring.
It create cell walls.
Why is Earth's magnetic field important to the survival of life?
it shields the Earth from harmful particles from the Sun
it is a bubble from the Earth
it holds in all oxygen, nitrogen, argon, & CO2
It is only imaginary so it doesn't do anything for Earth
Which of these is essential for the survival of astronauts taking short space walks (30 minutes or less)?
tool belt
oxygen supply
freeze-dried food
magnetic boots
Astronauts need to exercise while in space because, without gravity, the environment in space -
lacks breathable air, including oxygen humans need
makes astronauts consume more calories during missions
provides less resistance and weakens muscles and bones
does not allow the human body to retain heat like on Earth
