Definitions
Homeostasis
The ability of the body to maintain a stable internal environment
Serous Membrane
Serous=any clear, watery fluid; Most of the organs in the body are covered by a serous membrane
Osmosis
Movement of water molecules through a semipermeable membrane from an are of high concentration to low
Receptor
A cell or group of cells that receive stimuli
Pericardium
A sac that surrounds and protects the heart
Physiology
The study of how the body functions
Transitional Epithelium
Made up of several layers of cells that become flattened when stretched; found in the walls of the bladder to allow for expanding and holding liquid without rupturing
Hypertonic vs. Hypotonic
Hypertonic has a higher concentration of solutes while Hypotonic has a lower concentration of solutes
Negative Feedback
It helps maintain homeostasis by reducing a systems output
Avascular
Having few or no blood vessels; poor blood supply
Tissue
A group of similar cells that work together to perform a specific function
Mast Cell
Immune cells derived from the myeloid lineage
Hemolysis
The destruction of red blood cells
Positive Feedback
Intensifies a body's response to a stimulus
Hemidesmosomes
Attach the epithelial cells to the basement membrane
Histology
The study of microscopic structures of animal and plant tissues
Anatomy
The stud of the structure of an organism, including its parts and how they are organized
Phagocytosis
A cell engulfs and destroys foreign substances; bacterial or removes dead cells
Peritoneum
A serous membrane that lines the abdominal cavity and covers most of the abdominal organs
Mucin
Various mucoproteins that occur especially in secretions of mucous membranes
Viscera
The layer that covers the internal groups; Viscera=internal organs
Facilitated Diffusion
Passive transport that moves molecules across a cell membrane form an are of high concentration to low
Pinocytosis
Cells take in fluids along with dissolved small molecules
Supine
Laying on the back with face and torso facing up
Collagen Fibers
Protein strands that form the structural framework of connective tissue
