infertility
seminal vesicles are poorly developed or absent
high BS
glucose cannot get into cells
issue with facilitated diffusion
insulin is absent or cells are insulin sensitive
filtration
similar to rush hour
major supplier
forces body to pump heart
passive process
pushes flitrate from high pressure to low
facilitated diffusion
substance is helped to move across membrane
gylc is helped across the cell
acts like a revolving door
Active transport
active transport pumps
require addition of energy
transports potassim into cells where high concentration exists
endocytosis
used for cells intake of fluids
used for food when substance is too large to diffuse across membrane
cell membrane surround substances with small portion of membrane
exocytosis
transports thing out of cells
cells produce substance needed outside of cell
substance is surrounded by membrane
vesicle becomes part of membrane
