• this leukocyte is a cell mediator of inflammation: basophil
• B cells fight infections by: producing antibodies
• which of the following cells develop into macrophages?: monocytes
• megakaryocytes: give rise to platelets
• thrombopoietin promotes: platelet production in bone marrow
• hemopoiesis is: blood cell production
• oxygen levels are lower at higher altitudes. which organ would promoteincreased
numbers of reticulocytes in the blood at high altitudes?: kidney
• in what way does blood assist in immune function?: plasma antibodies andwhite blood
cells defend against pathogens
• the protein that is the major contributors to plasma osmolarity is: albumins
• red blood cell production is regulated by the hormone: erythropoietin
• an obstruction in blood flow to the kidneys would result in: increasederythropoiesis
• erythropoiesis is stimulated when: blood flow to the kidney declines
• type AB blood has which of the following characteristics: RBCs have boththe A&B
surface antigens and no ABO plasma antibodies
• anti-D antibodies are present in the blood of: Rh negative individuals whohave been
exposed to the D surface antigen
• which of the following combinations may result in the hemolytic diseaseof the newborn?:
mother Rh negative, baby Rh positive
• type A blood has antibodies in the blood plasma: anti-B
• the hormones that stimulates platelet formation is: thrombopoietin
• which of the following is a function of the skeletal system?: -body support
-protection of organs
-blood cell production
-calcium homeostasis
• the shaft of a long bone is: diaphysis
• a chamber within a bone normally filled with air is a: sinus
• which bones are classified as irregular in shape?: vertebra
• proximal and distal ends of a long bones are called: epiphyses
, • carpal bones are examples of bones: short
• the patella is an example of a bone: sesamoid
• the region of a long bone between the end and the shaft is known asthe: metaphysis
• what is not true about osteocytes?: -osteocytes stimulate the parathyroidhormone
-osteocytes take part in repair of damaged bone
-osteocytes maintain protein and mineral content of matrix
-osteocytes are located within lacunae
-osteocytes from cytoplasmic extensions within canaliculi
• a rounded passage or hole through a bone is called a: foramen
• through the action of osteoclasts: bony matrix is dissolved
• the structural units of mature compact bone are called: osteons
• the deposition of calcium salts in bone tissues is referred to as: calcification
• important steps in the process of endochondral ossification: 1. chondro-cytes enlarge and
the surrounding matrix begins to calcify
2. enlarged chondrocytes die
3. blood vessels grow around the edges of the cartilage
4. perichondrial cells become osteoblasts and produce a superficial layer of bone
• during appositional growth: bones grow wider
• major steps in the process of intramembranous ossification: 1. osteoblastsdifferentiate
within mesenchymal connective tissue
2. spicules of bone radiate out from the ossification centers
3. clusters of osteoblasts from osteoid that becomes mineralized
4. mesenchymal cells aggregate
• the ongoing process of tearing down and rebuilding bone matrix is called-
: remodeling
• correct steps in bone repair: 1. hematoma occurs
2. internal callus forms at the site of the injury
3. cartilage in the external callus is replaced by bone
4. osteoclasts and osteoblasts remodel the bone at the site of repair
• the styloid process, zygomatic process, and auditory ossicles are associ-ated with the:
