Human Body Systems & Genetics (5th Grade Science)

muscles that are not under your conscious control

muscular tube that moves food to the stomach using peristalsis or waves of muscle contractions.

consisting of many cells

muscles that you are able to control

the chemical factors that determine traits

characteristics that are inherited

The windpipe; a passage through which air moves in the respiratory system.

blood vessels that carry blood away from the heart

part of the central nervous system - conducts sensory, motor nerve impulses to & from the brain

digestive organ in which most chemical digestion takes place

body system consisting of the heart and blood vessels that circulate blood through the body

part of the central nervous system, located in the skull - controls most functions in the body

one or more bundles of fibers forming part of a system - conveys impulses of sensation, motion

the system for taking in oxygen and giving off carbon dioxide

large muscular sac that continues the mechanical and chemical digestion of food

one-celled microorganisms, some of which are beneficial and some of which cause disease

strong connective tissue that attaches muscle to bone

the fluid (red in vertebrates) that is pumped by the heart

cells and tissues that allow movement of an organ or body part

blood vessels that carry blood back to the heart

body system that breaks down food and absorbs nutrients

an organism with one single cell

brain, spinal cord, and nerves -regulates the body's responses to internal and external stimuli

the building blocks of all living things

connective tissue that is more flexible than bone and that protects the ends of bones 

respiratory organs inside the chest where blood picks up oxygen and loses carbon dioxide

to receive (a characteristic) from one's parents by genetic transmission

the hollow muscular organ located behind the sternum and between the lungs
