Question | Answer |
---|---|
Function of white blood cells | Destroy pathogens - fight of infection |
Function of schwann cells | Electricaly insulated neurons |
Functio of axon | Cary impulses away from the cell |
Dendrites | Carry impulses towards the cell |
Smooth muscle and example | Cells are tapered located in wall of arteries and veins and maintain BP...Located in the iris of the eye to regulate the size of the pupil |
Squamous | Cells are flat |
CuboidalSingle Layer | Cells are cube shaped |
Columnar | Cells are tall and narrow |
Simple | Single Layer |
Stratified | Layers of cells |
Location of Nerve tissue | found only in the nervous system |
Cardiac muscle - Organ involved - Function | Pump blood, heart, regulate only the rate of contraction |
Simple squamous epithelium - Characteristics - Functions | One layer of flat cells, very thin and very smooth, permit diffusion of gases, prevent abnormal blood clotting |
Stratified squamous - example - function | Many layers of flat cells, Keratinizing = dead, in the epidermis... Non Karatinizing = living, in the mouth |
Transitional epithelium - location - shape | lining of the bladder and ureters , shape is rounded when empty flat when full |
Cubodial epithelium function | secretes thyroxine to thyroid , secretes saliva, permit reabsorption of usedful material back to blood |
Parietal pleura | lines the chest wall |
visceral pleura | covers the lungs |
red blood cells - functions- effects of low RBC | Carry oxygen, effects of low RBC is anemia |
Why are platelets important | Prevent blood loss , blood clotting process |
Plasma Function | Transport nutrients , gases, and waste products |
Endocrine gland function | ductless glands, function is to secrete hormones |
Difference between exocrine glands and endocrine glands and examples | Exo has ducts - salivary glands Endo - Ductless - secrete hormones |
Extra Energy is stored where | Adipose tissue |
What doe endocrine glands secrete and where | secrete hormones in capillaries |
Muscle tissue involved with eye | Smoot tissue |
Mucous Membranes | Line body cavities that open to the environment |
Connective tissue related to the eye | Adipose tissue |
Treachea lining in relation to epithelial tissue | ciliated epithelium sweeps mucus with trapped dust and bacteria from inhaled air |
Function of mucus in the respiratory tract | Traps dust and bacteria |
Organs lined with mucus membrane | Respiratory , digestive, urinary, reproductive |
Fibrous connective tissue is what, in relation to strength | Flexible |
Osteocyles and their matrix | Bone - Made of calcium salts and collagen |
WHere are RBC's produced | Stem Cells |
Function of red bone morrow | Primary site of stem cells that produce blood cells |
Treachea in relation to connective tissue | keeps airway open |
where are digestive enzymes found | Columnar epithelial tissue |
joint capsule | fiberous connective tissue ...enclosed joint |
ossification | production of bone matic and begins in the center of each bone |
epiphyses | end of long bones...made of spongy bone covered w thin layer of compact bone |
diaphysis | shaft of long bones...made of compact bone and is hollow forming a canal withint the shaft canal contains yellow bone morrow mainly adipose tissue |
Estrogen and testosterone | promotes closure of the epiphyses of long bones... helps retain calcium in bones to maintain a strong bone matrix |
appendicular skeleton | supports the appendages or limbs |
tendon | connects bone to muscle |
where is red bone marrow found in long bones | epiphusis of the long bone |
Child bone growth begins where | growth plate |
osteoblast | bone producing cell...build up of bone |
Axial skeleton | skull vertebrea |
appendicular skeleton | arms, legs, shoulder, pelvis |
Strongest and larget bones in the back | lumbar |
Ribs corilate with what organ | Lungs |
Synthrosis | Immovable joints |
Calcetonin | decrease reabsorbtion of calcium |
Insulin | produced in the pancrease and helps with glucose |
Thyroxine | Increase rate of protein synthasis |
