What maintains the osmolarity and acid-base balance of the blood -Answer- Electrolytes and proteins Functions of blood -Answer- provide nutrients to cells, provide oxygen for cellular metabolism, removes by-products, carries the cells that protect the body against infection and invading organisms 3 groups of plasma proteins -Answer- albumin, clotting factors (mostly fibrinogen), lipoproteins (triglycerides, cholesterol, fatty acids) Albumin -Answer- function as carrier and control plasm...

NARM (CPM EXAM) II REVIEW QUESTIONS AND ANSWERS, GRADED A+ "peak day" - -the last day during which the cervical mucus is clear, slippery, and stretchy (isoimmunization) Hemolysis - -Hemolysis is caused by maternal IgG antibodies creating fetal anemia termed erythroblasis fetalis---the baby responds to the anemia by making more RBC which can cause fetal anemia termed hydrops fetalis. 2 shunts for fetal circulation - -foramen ovale, ductus arteriosus, and ductus venosus (Figure 37-1). ...

acanthocyte correct answer: "thorn cells"/spur cells - small spherical cells with thornlike projections - have no central pallor; have membranes with free cholesterol accumulating preferentially in outer bilayer, leading to decreased fluidity anemia correct answer: insufficient number of RBCs, characterized by inadequate tissue oxygenation ankyrin correct answer: large protein serving as high-affinity binding site for attachment of spectrin to inner membrane surface - binds to spec...

Hypoxia Low oxygen saturation of the body Anoxia absence of oxygen Hemoglobin (Hgb) blood test used to determine the concentration of oxygen-carrying components (hemoglobin) in erythrocytes. Issues that lead to poor oxygenation/ gas exchange Asthma Anaphylaxis Smoking Anemia Choking COPD Low Hgb Fetal hemoglobin (hbf) unique form of hemoglobin that has higher affinity for oxygen than does adult hemoglobin; after birth, liver rapidly destroys fetal rbcs & baby's erythroblasts start producing...
