increased erythropoiesis.
Why is the left ventricle more muscular than the right ventricle?
must generate enough force to propel blood through the systemic circuit, whereas the right ventricle must generate only enough force to propel blood the short distance from the heart to the lungs in the pulmonary circuit.

During the cardiac cycle,
the QRS complex of the ECG precedes the increase in ventricular pressure.
Describe the areas of the heart supplied by the right and left coronary arteries.
the right coronary artery supplies blood to the right atrium, portions of both ventricles, and the conducting system. The left coronary artery supplies blood to the left ventricle, left atrium, and interventricular septum
How do basophils respond to tissue damage?
They enter damaged tissue and release a variety of chemicals, including histamine, which promotes inflammation.
Describe the functional aspects of RBCs.
They have a large surface area — to — volume ratio, exhibit the ability to form stacks, and they are flexible.
define hemolytic disease of the newborn
condition in which maternal Rh antibodies attack and destroy fetal Rh-positive red blood cells, resulting in anemia.
Platelets are
cytoplasmic fragments of large cells.
A typical adult hematocrit is
higher in males than females.
Which of the following descriptions best matches the term colony stimulating factor
hormone that regulates blood cell formation
An increased mean corpuscular hemoglobin concentration is termed
hyperchromic
Aged and damaged erythrocytes are broken down by macrophages in all of the following places except the
kidney
The circumflex branch and the anterior interventricular artery are branches of the
left coronary artery.
Which of the following is false concerning neutrophils?
less abundant than lymphocytes
If bile ducts are blocked, which of the following would not occur
less hemolysis would occur
The extrinsic pathway of coagulation is initiated by the
release of tissue factor (Factor III) by damaged endothelium.
People with type AB blood are considered the "universal recipient" for transfusions because
their blood lacks A or B antibodies.
The heart beats approximately ________ times each day.
100,000

an increased reticulocyte count.
The inferior point of the heart is called the
apex

prevent the atrioventricular valves from reversing into the atria.
Which of the following is not a function of blood?
produce hormones
The chief differences between plasma and interstitial fluid involves the concentration of
proteins

pulmonary valve
Name the four chambers of the heart.
right atrium, right ventricle, left atrium, left ventricle
The marginal branch and posterior interventricular branch are branches of the
right coronary artery.
What is hematology?
study of blood, blood-producing organs, and blood disorders.
