Pass
Osmosis - 🧠 ANSWER ✔✔a process by which molecules of a solvent tend
to pass through a semipermeable membrane from a less concentrated
solution into a more concentrated one, thus equalizing the concentrations
on each side of the membrane
Diffusion - 🧠 ANSWER ✔✔Diffusion is the net passive movement of
particles (atoms, ions or molecules) from a region in which they are in
higher concentration to regions of lower concentration
Hydrostatic Pressure - 🧠 ANSWER ✔✔The pressure exerted by a fluid at
equilibrium at a given point within the fluid, due to the force of gravity
Endocytosis - 🧠 ANSWER ✔✔the taking in of matter by a living cell by
invagination of its membrane to form a vacuole.

,Exocytosis - 🧠 ANSWER ✔✔a process by which the contents of a cell
vacuole are released to the exterior through fusion of the vacuole
membrane with the cell membrane.
Phagocytosis - 🧠 ANSWER ✔✔the ingestion of bacteria or other material by
phagocytes
Pinocytosis - 🧠 ANSWER ✔✔the ingestion of liquid into a cell by the
budding of small vesicles from the cell membrane.
Hypertrophy - 🧠 ANSWER ✔✔the enlargement of an organ or tissue from
the increase in size of its cells.

, Apoptosis - 🧠 ANSWER ✔✔the death of cells that occurs as a normal and
controlled part of n organism's growth or development
Macrophages - 🧠 ANSWER ✔✔a type of white blood cell that engulfs and
digests cellular debris, foreign substances, microbes, cancer cells, and
anything else that does not have the types of proteins specific to healthy
body cells on its surface in a process called phagocytosis
Self-antigens - 🧠 ANSWER ✔✔any molecule or chemical group of an
organism which acts as an antigen in inducing antibody formation in
another organism but to which the healthy immune system of the parent
organism is tolerant
Delayed hypersensitivity - 🧠 ANSWER ✔✔hypersensitivity (as in a
tuberculin test) which is mediated by T cells and in which the typical
symptoms of inflammation and induration appear in an individual previously
exposed to an antigen after an interval of 12 to 48 hours following a
subsequent exposure
Anaphylaxis - 🧠 ANSWER ✔✔an acute allergic reaction to an antigen to
which the body has become hypersensitive
