What areas of the heart are supplied by the left coronary artery?
Anterior wall of heart and most of left ventricle
What is the order of the blood vessel types that a red blood cell would pass through as the blood leaves the heart, travels to a tissue, and then returns to the heart?
Artery, arteriole, capillary, venule, vein
Lymphatic capillaries
Close-ended vessels consisting of simple squamous epithelium
Platelets are more numerous than red blood cells.
False
Platelets are small cells containing a nucleus but lacking organelles.
False
The valves of the heart allow blood to flow in different directions through the heart based upon the pressure differences from the pulmonary and systemic circulations.
False
Foreign antigen description
Introduced from outside the body
Thoracic duct
Lymph from the lower limbs enters blood circulation here
Right lymphatic duct
Lymph from the right upper limb enters blood circulation here
Which vessel is often used to draw blood from a patient?
Median cubital vein
Self-antigen description
Molecules produced by the body
Which of the following layers forms the majority of the thickness of the heart wall?
Myocardium
Platelets
Play an important role in hemostasis
Foreign antigen example
Pollen
Where is the vasomotor center located?
Pons and medulla oblongata
Self-antigen example
Recognition of tumor antigens
Lymphatic vessels
Resemble small veins and contain valves to prevent backward flow of lymph
Contractions of the heart generate blood pressure, which is responsible for moving blood through the blood vessels.
True
Platelets are produced in the red bone marrow from megakaryocytes.
True
Platelets play a role in preventing blood loss.
True
The heart separates the pulmonary and systemic circulations and ensures better oxygenation of the blood flowing to the tissues.
True
The rate and force of heart contractions change to meet the metabolic needs of the tissues which can vary based on different conditions.
True
Which of these transfusions would be least likely to cause a transfusion reaction?
Type O+ blood transfused into a type B+ patient
In hemolytic disease of the newborn,
antibodies from the mother cross the placenta and affect the fetus.
Type AB blood
has both A and B antigens on the red cells.
Blood is moved through the vascular system by
pressure gradients created by the heart.
Germinal centers are the sites of
proliferation of lymphocytes in the lymph nodes.
