Tissues and Organ Systems Flashcards
Learn all the tissues and organ systems
What are the four main types of tissues?
Epithelial, Connective, Muscle, Nerve
What are the four C’s?
Connect, cover, communicate, contract
What is epithelial tissue and what does it do? Give an example.
It is a thin lining that protects internal organs from external bacteria and lines major organs. example: skin
What is nerve tissue and what does it do? Give an example.
Long thin cells with branches which sends signals to the brain and provide communication throughout the body. Example: brain
What is connective tissue and what does it do? Give an example.
Various types of cells and fibres held together by a liquid, gel or solid which supports and insulates. Example: bone, tendons, ligament
What is muscle tissue and what does it do? Give an example.
Bundles of long cells capable of shortening and contacting providing movement. Example: heart, bicep, triceps
Which body system protects the body from the outside?
Integumentary
Which body system takes in oxygen and disposes of carbon dioxide?
respiratory
Which system filters blood and disposes of waste?
urinary
Which system extracts nutrients and disposes of fecal matter?
Digestive
Which system communicates to the brain?
nervous
Which system produces eggs and sperm?
Reproductive
Which system provides support for the body?
Skeletal
Which system helps with movement?
Muscular
Which system circulates blood?
Circulatory
Which system relays chemical messages (hormones) through the body?
Endocrine
Which system removes and destroys invading bacteria?
Lymphatic
List all 11 organ systems
Integumentary, muscular, skeletal, nervous, endocrine, lymphatic, reproductive, digestive, circulatory, respiratory, urinary.
What is the cell theory?
Cell theory states that all living organisms are composed of one or more cells. They are the basic structure and function in all organisms. all come from pre-existing cells. the entire organism depends on the total activity of its independent cells.
What is a prokaryotic cell?
The smallest living cells. do not contain a nucleus, have a cell wall and have a nucloid that only contains a single loop of DNA.
What is a Eukaryotic cell?
Have a nucleus, larger cell and more complex. Contain organelles such as mitochondria.
List two similarities between prokaryotic and Eukaryotic cells
both contain dna, have ribosomes
What is homeostasis? Why is it important?
To maintain balance throughout the body. Humans are homeostasis and our body must remain at one temperature to function correctly.
What is a mitochondria?
‘Powerhouse’ of the cell. Provides energy in the form of ATP.
