Biology Flashcards
Trachea
a large membranous tube reinforced by rings of cartilage, extending from the larynx to the bronchial tubes and conveying air to and from the lungs; the windpipe.
Rib cage
A protective layer of ribs surrounding the heart/lungs
Heart
An organ that pumps oxygenated blood around the body
Diaphragm
A dome shaped muscle that increases the volume of your chest therefore letting your lungs expand
Lung
It holds the oxygen
Bronchiole
any of the minute branches into which a bronchus divides.
Bronchus
any of the major air passages of the lungs which diverge from the windpipe.
Alveoli
any of the many tiny air sacs of the lungs which carry the air into the cells
Intercostal muscles
They help the rib-cage Move
Cell
The building blocks of everything
Tissue
What your organs and muscles are made of
Organ
Vital things (eg heart) made out of tissue
Organ system
A set of organs(eg skeletal system) working together to do one thing
Hierarchy of organisms
Organism Organ system Organ Tissue Cell
Tendon
What holds your muscles to your bone
Ligament
Holds your bones together in a joint
Bone
A part of your body that keeps you uprite
Joint
The thing that connects your bones
Muscle
These makes your bones move
Antagonistic pairs
A pair of muscles that work oppositely to move your bones. Eg biceps and triceps
Synovial fluid
A fluid that keeps your bones from wearing each other out
Cartilage
Cartilage stops your bones from rubbing therefore wearing each other out
Bone marrow
These are in side your bones and make red blood cells
Inhalation
When you breath in your chest expands and moves up then out
