Absorption
the process of absorbing nutrients into the body after digestion
Alimentary canal
digestive tube that extends from the mouth to the anus
Amphiarthroses
slightly movable joints
Anatomy
study of body structure
Anatomical position
erect, feet forward, arms at side with palms facing forward, head facing forward
Appendicular skeleton
the part of the skeleton that includes the pectoral girdle and the pelvic girdle and the upper and lower limbs
Appositional growth
growth at the outer surface of a bone during endochondral ossification, resulting in an increase in the bone's thickness
Articulation
the act of joining things in such a way that motion is possible
Axial skeleton
the part of the skeleton that includes the skull and spinal column and sternum and ribs
Bilateral symmetry
the property of being symmetrical about a vertical plane
Bile
a substance produced by the liver that breaks up fat particles
Bursa
a small fluid-filled sac located between movable parts of the body especially at joints
Chyme
a semiliquid mass of partially digested food that passes from the stomach through the pyloric sphincter into the duodenum
Colon
the part of the large intestine between the cecum and the rectum
Contralateral
opposite side
Deep
large in quantity or size
Defecation
the elimination of fecal waste through the anus
Diarthroses
freely movable joints
Digestive system
the system that makes food absorbable into the body
Duodenum
the part of the small intestine between the stomach and the jejunum
Eccrine glands
most numerous, important, and wide spread of the sweat glands, mostly on forehead, upper lip, palms and soles, not hair follicles, regulate temperature,

formation of blood cells
Homeostasis
process by which organisms maintain a relatively stable internal environment
Inorganic matrix
calcium phosphate: forms needle like crystals that are deposited around the collagen fibers of the organic matrix; accounts for most of the hardness/strength of bone in resisting compression

Mitosis
cell division in which the nucleus divides into nuclei containing the same number of chromosomes
Negative feedback loops
Self-corrective mechanisms in physiology, change in the body that moves conditions about or below a set point.---Keep internal environment stable. Ex: can't hold your breathe for a long time
Organic matrix
collagen fibers
Peristalsis
rhythmic muscular contractions that squeeze food through the esophagus into the stomach
Physiology
processes and functions of an organism
Positive feedback loops
A feedback loop in which change in a system is amplified.
