Solutions Graded A+
what organism level is you skin classified as - Correct Answersintegumentary system
what boundary organ system is the kidney in - Correct Answersurinary system
Na+ transport happens between which compartments - Correct Answersblood plasma and
tissue fluid (within the ECF)
what kind of transport does Na+ use within the ECF - Correct Answerspassive, diffuses
through the pores of the capillary wall
what % of cytoplasmic ATP is used to run the Na-K pump in most human cells - Correct
Answers30%
How is homeostasis often controlled - Correct Answersnegative feed back loop
what is it a NEGATIVE feed back loop - Correct AnswersTh initial change in condition
detected by the receptors is responded to by the effector with the OPPOSITE response to
what was detected to maintain homeostasis
where are most control centers for homeostasis - Correct Answersnervous system and
endocrine system
what are the differences between primary tissues and embryonic germ layers - Correct
Answers- ectoderm creates nervous tissue
- mesoderm creates muscular and connective tissue
- endoderm creates epithelial tissue
,cleavage - Correct Answersmitosis (divisions) wihtout growth
growth - Correct Answersincrease in size of daughter cells
morphogenesis - Correct Answersrate at which changes occur to shape an embryo
differentiation - Correct Answerscells acquire specific structures and function
function of fibroblast cells - Correct Answerssecretes collagen fibers to creates our fibers
function of the basement membrane - Correct Answersanchors epithelial tissue to loose
connective tissue
secondary ossification - Correct Answersoccurs after birth, corresponds with the epiphysis
simple squamous epithelium - Correct Answersforms membrane that allows selective
diffusion of materials to pass through
which cells lay down fresh bone matrix? - Correct Answersosteoblasts
which cells recycle bone matrix? - Correct Answersosteoproginator cells
where are these cells located in bone marrow? - Correct Answersbone tissue
what type of bone marrow is found within the spaces of spongy bone? - Correct
Answersyellow bone marrow
how do blood vessels invade cartilage patterns if cartilage is avascular? - Correct
Answersthrough nutrient foramina (holes in the diaphysis of bone)
primary ossification - Correct Answersbegins before birth and forms long central shaft in
long bones that corresponds with the diaphysis
, what germ layer is bone tissue derived from? - Correct Answersmesoderm, middle
embryonic germ layer
which bone tissue organization is stronger: spongy or compact? - Correct
Answerscompact
ectoderm - Correct Answers"inner skin" produces nervous tissue
mesoderm - Correct Answers"middle skin"; develops into muscle tissue and much of the
circulatory, reproductive, and excretory systems
organ - Correct Answerstwo or more kinds of tissues that together perform special body
functions that they cannot accomplish alone
4 yuppies of membranes - Correct Answersmucus, serious, synovial, cutaneous
mucus membrane (location, function, secretion) - Correct Answerslines cavities and tubes
that open to the outside of the body
location:
function: lubrication and protection
secretion: mucosa
cutaneous membrane - Correct AnswersThe skin; composed of epidermal and dermal
layers
location: skin
function: protection
secretion: sebum
