BMS 300 LATEST 2026 EXAM QUESTIONS AND ANSWERS
GUARANTEE A+
✔✔In the three steps of urine formation in the nephron, blood is filtered in the -
✔✔glomerular capsule
✔✔The —- are paired organs that transport urine from the kidneys and their lumen is
lined by —- epithelium to permit distension/stretching - ✔✔ureter, transitional
✔✔During isovolumetric relaxation there is no change in the ventricular volume because
the ventricular pressure is —- than aortic pressure but —- than atrial pressure -
✔✔lower, higher
✔✔As the heart —-, the —- valves open causing blood to flow into the left and right
ventricles - ✔✔relaxes, left and right AV
✔✔In red blood cells (RBC)/erythrocytes, oxygen is transported by binding to the iron in
the —- of hemoglobin protein - ✔✔Heme group
✔✔—- promotes the development of hematopoietic stem cells (HSCs) into the myeloid
lineage, including neutrophils, eosinophils, basophils, and monocytes - ✔✔GM-CSF
✔✔When a person is not starving, —- would be used as a fuel by slow fibers, whereas
—- would be used as a fuel by fast fibers - ✔✔fats, glucose
✔✔A delay in the electrical signal transmission from the atria to the ventricles, resulting
in a prolonged PR interval on an electrocardiogram, most likely indicates a —- degree
atrioventricular (AV) heart block - ✔✔First
✔✔In the troponin complex, the —- subunit binds actin in the absence of calcium but it
binds TnC in the presence of calcium - ✔✔Troponin 1 (Tn1)
✔✔In smooth muscles, a mutation that inactivates the —- will most likely cause the
myosin to remain bound to actin - ✔✔myosin light chain phosphatase enzymes
✔✔During hemoglobin recycling, the heme group is broken down into —- a green
pigment - ✔✔biliverdin
✔✔An antibody has an abnormality in the constant segments of the heavy chains. It is
most likely that this antibody —- - ✔✔cannot be recognized by macrophages
, ✔✔You are performing bicep curls in the gym. Isometric contraction occurs when you —
- - ✔✔hold a dumbbell in place
✔✔In the heart, autorhythmic cells produce action potentials spontaneously because
they express Hyperpolarizaiton-activated, cyclic nucleotide gated (HCN) channels that
are permeable to —- ions - ✔✔Na+ and K+
✔✔Which of the following cells are most directly responsible for innate immunity? -
✔✔Macrophages
✔✔In the pressure volume loop, the aortic pressure is indicative of —- while the end
diastolic volume is indicative of —- - ✔✔after load, preload
✔✔The blood flow velocity increases from —- because it flows from a greater to a
smaller cross-sectional area - ✔✔capillaries to veins
✔✔—- are leukocytes/white blood cells (WBC) with a multilobed nucleus which stain
with a neutral die. They arrive first at the site of injury, phagocytose bacteria, and
contribute to the formation of pus - ✔✔neutrophils
✔✔The autonomic nervous system can —- heart rate by causing greater —- of the
membrane potential of pacemaker cells - ✔✔more than one answer is possible
✔✔Abnormal T waves in the EKG can be most likely indicative of defects in —- -
✔✔ventricular diastole
✔✔Cardia output (CO) is the volume of blood pumped through the circulatory system in
1 minute (ml/min). Therefore, CO is inversely associated with —- but directly associated
with —- - ✔✔end systolic volume, heart rate
✔✔The interaction between CD8 and MHC Class 1 proteins is a crucial step in
activating —- - ✔✔cytotoxic T cells
✔✔If a cell is infected with the swine flu virus, it will alert the cells in the nearby vicinity
by releasing —- - ✔✔interferons
✔✔If you want to study how B lymphocytes are activated, then you would harvest cells
from the —- - ✔✔spleen
✔✔Which of the following is common to smooth, skeletal, and cardiac muscles -
✔✔myosin heads hydrolyze ATP
