| Lines body cavity closed to the exterior, simple squamous epithelium resting on thin layer of loose connective tissue | Body membrane, serous |
| Synovial and meninges are types of | Body membranes |
| Defensive response to tissue damage intented to recruit immune system | Inflammation |
| Symptoms of inflammation | Temp, redness, swelling and pain |

| All organisms are composed of one or more cells | Cell theory |
| Cells are the smallest living units of all living organisms | Cell theory |
| Cells arise only by division of a previous existing cell | Cell theory |
| Theodor Schwann 1839, proposed the cell theory | Cell theory |
| Before nucleus, p or e | Prokaryotes |
| True nucleus, p or e | Eukaryotes |
| Bacteria and archaea p or e | Prokaryotes |
| Protests, fungi, plants, animals | Eukaroytes |
| Structurally more complex p or e | Eukaryotes |
| Structurally simple | Prokaryotes |
| Kidney glo, airsac of the lungs | Simple squamous epithelial |
| Kidney tubules, ovary | Simple cuboidal epithelium |
| Digestive tract, uterus | Simple columnar epithelial |
| Esophagus, mouth, vagina epidermis skin | Stratified squamous epithelial |
| Uterers, bladder, part of urethane | Transitional epithelium |
| Male sperm | Pseudo stratified columnar |
| Highly specialized nerve cells that generate and conduct nerve impulses | Neurons, neuroglia |
| Function to cover | Body membrane |
| Function to protect | Body membrane |
| Function to reduce friction | Body membrane |
| Body membrane is a collection of | Epithelial and connective tissues |
| are most concerned with absorption, secretion, and filtration, very thin, protection is not their specialties | simple epithelia |
| fashions the glands of the body | glandular epithelium |
| forms the outer layer of the skin, dips into the open cavities of the urogenital, digestive, and respiratory systems; convers the walls and organs of the closed ventral body cavity | covering and lining epithelium |
| the simplest of the epithelia | simple squamous |
| allows material to pass by diffusion and filtration, located in kidneys glomuri, air sacs of lungs, line ventral body cavity | simple squamous epithelium |
| function to secrete and absorb, simple, kidney tubules, ducts and secretory | simple cuboidal epithelium |
| function absorption, secretion of mucous, enzymes, ciliary function, digestive tract gallbladders, bronchi, uterine tubes, uterus | simple columnar epithelium |
| single layer of cells with different heights, mucus cilia, secretes substances particularly mucous by ciliary action, male sperm ducts, trachea | pseudostratified columnar epithelium |
| thick membrane composed of several layers, keratin, protect underlying tissues abrasion, keratin epidermis of the skin | stratified squamous |
| looks like stratified and squamous cuboidal, stretches, urine, ureters, bladder, part of uretha | transitional epithelial |
| a sticky, thick fluid secreted by mucous glands and mucous membranes, keeps the free surface of membranes moist | mucous |
| is the skin,, organ system that consist of keratinized stratified squamous epithelium (epidermis) attached to thick layer of connective tissue (dermis) | cutaneous membrane |
| membrane exposed to the air and dry temperature | cutaneous membrane |
| membrane lines all body cavities that open to the outside of the body such as hollow organs of the digestive, respiratory, and urogenital tracts, | mucous membrane |
| lines joints cavities and consist of connective tissue only, articulating bones are separated by fluid containing joint cavity | synovial |
| moist membranes found in closed ventral body, consist of simple squamous epithelium on a thin layer of loose connective tissue | serous membrane |
| the most abundant and widely distributed of the primary tissues, but its amount in particular varies | connective tissue |
| four main classes of connective tissue | blood, bone, cartiliage, and connective tissue proper |
