study of body functions | physiology |
organism cell or organelles, the ability to move substances | movement |
the ability to detect and respond to stimuli internal and external | responsiveness |
size of number of cells | growth |
new cells or new organism | reproduction |
releasing energy from foods | respiration |
breakdown of macromolecules | digestion |
moving material through membranes into body | absorption |
changing absorbed material into other compounds | assimilation |
moving substance throughout body | circulation |
removing metabolic wastes | excretion |
all the chemical reactions in the body | metabolism |
levels of structural organization from smallest particle of matter to most complex | cell, tissues, organ, organ system. |
maintaining a stable internal environment | homeostasis |
vertebral canal | spinal cord |
thoracic | shoulder to diaphragm |
pleural | lungs |
pericardial | heart |
mediastinum | in between to lungs |
toward the head | superior |
away from the head | inferior |
toward the front of the body | anterior |
toward the back of the body | posterior |
toward the midline | medial |
away from the midline | lateral |
toward the point of attachment | proximal |
away from the point of attachment | distal |
toward the surface of the body | superficial |
away from the surface | deep |
maintaining a stable internal environment | homeostasis |
the chemical reactions in the body | metabolism |
list one body homeostatic mechanisms | temperature, blood sugar, blood pressure |
an internal change causes a response that reverses the ordinal stimulus | negative feedback |
rare. a response enhances the original stimulus | positive feedback |
vertebral canall | spinal cord |
adominal | diaphragm to pelvic |
framework, protection...sym | skeletal sym |
contraction...sym | muscular sym |
sense internal and external changes, and sends messages...sym | nervous sym |
secretes hormones...sym | endocrine sym |
carries materials to cells...sym | cardiovascular sym |
carries fluids back to blood and provides protection...sym | lymphatic sym |
breaks down and absorbs nutrients...sym | digestive sym |
oxygen into blood and carbon dioxide out...sym | respiratory sym |
removes wastes and excess h2o...sym | urinary sym |
lengthwise plane- left and right sides | sagittal |
crosswire plane- top and bottom halves | transverse |
lengthwise plane front and back halves | frontal/coronal |
similar cells specialized to carry out one function | tissues |
study of tissues | histology |
four types of tissues in the human body | epithelial, connective, muscle, nervous |
function of epithelial tissue | covers organs, produces glands, lines cavities |
shape of squamous | thin flattened |
shape of cuboidal | cube shaped |
shape of columnar | tall, elongated |
shape of transitional | changes shape when stretched |
single layer of flat cells, absorption | simple squamous |
single layer of cube cells, absorption and secretion | simple cuboidal |
single layer of tall cells, protection, secretion, and absorption | simple columnar |
appear layered but are not usually ciliated with goblet cells | pesudostratified columnar |
many layered flat cells | stratified squamous |
two to three layers of cube cells | stratified cuboidal |
several layers of tall cells | stratified columnar |
secrete onto surfaces or cavities and an example...gland | exocrine glands, ex: salivary, sweat |
secrete into the blood and an example...gland | endocrine glands, ex: thyroid |
functions of connective tissues | bind structures, support protection |
fixed cells that produce matrix fibers | fibroblasts |
wandering cells that clear dead and foreign particles | macrophages |
near blood vessels to prevents clotting and participate in allergic response | mast cells |
thick protein fiber bundles, very strong and example...fiber | collagenous, ex: ligaments |
thin protein fibers that stretch and recoil and example...fiber | elastic, ex: skin, vocal cords |
thin collagen fibers, branched and example...fiber | reticular, ex: spleen |
thin membranes fibroblasts far apart, ecm a gel with many collagen and elastin fibers, found deep to most epithelial layers...connt tissue | loose or areolar |
fat storage cells, subcutaneous between muscles around heart and kidneys. cushions, insulates cells...connt tissue | adipose |
few cells, ecm of closely packed collegan and elastic fibers found in tendons, ligaments...conn tissue | dense |
ridige ecm provides, support, framework, cushioning at joints...conn tissue | cartilage |
cartilage cells reside in lacunae...connt tissue | chondrocytes |
ridige ecm. collagen surrounds cells, supports, protects, mineral storage...connt tissue | bone |
bone cells. central canal provides transport into bones, canaliculi are tunnels between cells...connt tissue | ostepcytes |
fluids ecm, plasma transports material...connt tissue | blood |
muscles tissues functions | contract to provide movement |
voluntatry, attaches to bone, striated, multinucleated elongated cells...mus tissue | skeletal |
involuntary no striations, spindle shaped, mononucleated found in various organs, blood vessels...mus tissue | smooth |
involuntary striated branched, momoncleated...mus tissue | cardiac |
nervous tissues functions | sense changes, transmits impulses |
produced and needed by the body | secreation |
waste leaving the body | excertion |
