the cells
formed from chemicals and structures
calls are found in all living things
some in single cell
some verve cells can be 2 feet long or longer
cells can be flat, round, and thread-like
7.5 trillion cells found in one human body that work together to allow for proper functioning of body
4 types of molecules
lipids
carbohydrates
proteins
nucleic acids
cells are made up of organelles
organelles
made up of even smaller substances called atoms
atoms
building blocks of all matter
passive transport
divided into 4 types
filtration
diffusion
facilitated
similar to crowd of people being pushed through turnstiles during rush hour
carrier mediated passive transport
osmosis
water travels through selectively preamble membrane
necessary to move oxygen from lungs to blood stream
symptoms of CF (cystic fibrosis)
nutritional defects
increased risk of respiratory
difficulty breathing
alveoli
gas exchange takes place
hemoptosis
coughing up blood
pneumophorax
collapsed lung
copulmonate
right sided heart failure
residual volume
is the amount of air that remains in a persons lungs
cystic fibrosis diagnosis
postnatal genic testing
prenatal genital testing
testing pulmonary function
testing amount of sodium in sweat
pilocarpine test
treatment
no cure
live up to age 35
active transport
endocytosis
exocytosis
active transport types
endocytosis
in-digesting substances that are too large to diffuse across the cell membrane via vesicle
cytoskeleton
a microscopic network of protein filaments and tubules in the cytoplasm of many living cells, giving them shape and coherence.
flagella
a slender threadlike structure, especially a microscopic whiplike appendage that enables many protozoa, bacteria, spermatozoa, etc., to swim.
4 phases of mitosis
metaphase
anaphase
prophase
telophase
the first stage of cell division, before metaphase, during which the chromosomes become visible as paired chromatids and the nuclear envelope disappears. The first prophase of meiosis includes the reduction division.
the second stage of cell division, between prophase and anaphase, during which the chromosomes become attached to the spindle fibers.
the stage of meiotic or mitotic cell division in which the chromosomes move away from one another to opposite poles of the spindle.
the final phase of cell division, between anaphase and interphase, in which the chromatids or chromosomes move to opposite ends of the cell and two nuclei are formed.
