Cell
the process by which a cell becomes specialized to perform a specific function
cellular diffrentation
thin sheet of tightly packaged cells that covers body surfaces and lines internal organs and body cavities
Epithelial tissue
Can diffrentiate into any type of cell, found in the human embryo at the blastocyst stage
Embryonic Stem cells
a cell that can diffrentiate into diff types of cells
Stem Cell
work to perform a major vital body function such as digestion, specific function
organ systems
trachea bronchioles pharynx/larynx mouth/nose bronchi alveoli
Mouth/nose - pharynx/larynx - trachea - bronchi - bronchioles- alveoli
a structure composed of diffrent tissues working together to perform a complex body function 100p
Organ
a group of specialized cells containing proteins that can contract and enable the body to move
Muscle tissue
found in bone marrow
Embryonic stem cells
found in brain and sensory organs
Nerve tissue
An individual animal plant, or single celled life form 100p
Organisim
resppitatory tracts are lined with __ that secrete mucus
epithelial cells
cannoto diffrentiate into all type of cells
Tissue Stem Cells
Passage for air to trachea, ring like muscual tube
Pharynx
group of cells with similar structure and function 100p
Tissue
breathing out
Expiration/exhalation
Hair like structures that protude from cells
Cilla
Conducts electrical signals from one part of the body to another
Nerve tissue
thin muscles under lungs, controls breathing
Diapghram
muscle that sits below the lungs
Diapghra=m
when lungs fill with air, the muscles between the lungs are called
intercostal muscles
muscular contractions that move food down the esophagus
