Chapter 5 Anatomy And Physiology Flashcards
morphology
is the science or study of the structure of an organism or body
atoms
consist of subatomic particles that all substances are composed of.
carbon
hydrogen
oxygen
nitrogen
cells
are basic functional units of all living matter
epithelial cell
nerve cell
muscle cell
tissues
are collections of similar cells that carry out specific bodily functions
epithelial tissues
nerve tissues
muscle tissues
connective tissues
organs
a combination of tissues and cells that form a complex structure to perform a certain function within the system
lung
brain
stomach
kidney
organ system
is several organs working together to perform a bodily function
respiratory system
nervous system
digestive system
circulatory system
protoplasm
is a colorless, jelly like substance in which food elements, such as protein, fats, carbs, mineral salts, and water are present
molecules
atoms arranged in specific patterns and structures
sugars
proteins
water
organelles
mitochondrian
nucleus
ribosome
cytoplasm
is all of the substance within the cell wall other than the nucleus
nucleus
the main central body of living cells that contains the genetic information for continuing life
living cells differ from each other by… (4)
size, shape, structure, function
cell membrane
permits soluble substances to enter and leave the protoplasm
cytoplasmic organelles
discrete structures within a cell, having specialized functions, identifying molecule structures, and a distinctive chemical composition
differentiation
is the repeated division of the ovum during early developmental stages. resulting in specialized cells that differ from one another
mitosis
is the process of cell division in which a cell divides into two cells identical to the parent cell
IPMAT
Interphase Prophase Metaphase Anaphase Telophase
meiosis
is cell division that takes place in the sex organs of animals to produce the egg and sperm required for fertilization, and in which the resultant cells have only one half the number of hereditary chromosomes as the parent cell
the activity of the cells can be divide into what 3 categories?
vegetative,
growth and reproduction
specilaized
metabolism
is the process taking place in living organisms whereby the cells are nourished and carry out their activities
anabolism
is the process of building up of larger molecules from smaller ones
catabolism
is the breaking down of larger substances into smaller ones
