Specialized Cells Flashcards
What is a multicellular organism
A organism that consist of multiple cells
What is the Epithelial Cell
They are found on the surfaces of organisms, they also line internal structures like the trachea and lungs.
What is the CILIATED Epithelial Cell
These form the lining of the air passages in the lungs, trachea and bronchi, Fallopian tubes. These cells have tiny little hairs called cilia that beat back and forth to create current in the fluid next to their surface. They also trap dust and pathogens.
What is the Squamous Cell
These are very thin cells. They form the outer layer of the skin and line the tiny air pockets in the lungs, arteries and veins, and form the walls of blood capillaries .
What is the Nerve Cell
A type of cell that receives and sends messages from the body to the brain and back to the body. The messages are sent by a weak electrical current. Also called neuron.
What is a neuron
Neurons are information messengers. They use electrical impulses and chemical signals to transmit information between different areas of the brain, and between the brain and the rest of the nervous system.
What are the muscle cells
These cell makes up muscles in our gut, reproductive system , arteries, veins.
What are most cells organised into
CELLS are organised into TISSUES, TISSUES are organised into ORGANS, ORGANS are organised into ORGAN SYSTEMS.
What are the Gamete cells
Also called ‘sex cells’. The gametes are not organised into tissues. They are reproductive cells. Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each chromosome.
