This is a diagram of a tube of blood, after spinning down in a centrifuge. What is the red arrow pointing to?
What is red blood cells?
What is erythrocytes?
100
If a patient's red blood cells agglutinate (clump) when mixed with anti-A serum but not with anti-B serum, and do agglutinate with anti-Rh serum, this is their blood type.
What is A Positive (A+)?
100
Identify this white blood cell. 
What is Basophil?
100
Identify the wave, segment, or interval at "B".
What is ST segment?
100
Identify the layer of the blood vessel wall at "B". 
What is Tunica Media?
200
This is a diagram of a tube of blood, after spinning down in a centrifuge. What is the green arrow pointing to?
What is the buffy coat?
200
A person with B antigens and Rh antigens on their red blood cells, and anti-A antibodies in their plasma, would be this blood type, making them a universal recipient for red blood cells if they were also Rh positive.
What is B positive (B+ blood)
200
Identify the formed element at "A"
What is neutrophil?
200
Identify the appropriate vessel, structure, or feature for letter A.
What is the Pulmonary trunk?
200
These muscular blood vessels carry oxygenated blood away from the heart to the rest of the body, and typically have the thickest, most elastic walls.
What are arteries?
300
These biconcave disc-shaped cells, lacking a nucleus, are primarily responsible for oxygen transport.
What are red blood cells?
What are erythrocytes?
300
This blood type has both A and B antigens on its red blood cells, no Rh antigens, and neither anti-A nor anti-B antibodies in its plasma.
What is AB negative (AB-)?
300
These cells are born in the bone marrow and migrate from the peripheral blood system after a few hours, into loose connective tissue in the respiratory and gastrointestinal tracts.
What are Eosinophils?
300
Identify the wave, segment, or interval at "A".
What is P wave?
300
identify the layer dominated by connective tissue labeled "A"
What is Tunica Externa?
400
This iron-containing protein gives red blood cells their red color and binds reversibly with oxygen.
What is Hemoglobin?
400
Please identify the blood type from the results below.
What is B Negative?
400
Identify the cell below
What is a Monocyte?
400
Identify the chamber labeled by arrow A
Left atrium
400
Identify the layer of the blood vessel wall adjacent to the lumen labeled "C"
What is the tunica intima?
500
This is a diagram of a tube of blood, after spinning down in a centrifuge. What is the yellow arrow pointing to?
What is plasma?
500
In an emergency, this blood type is considered the universal donor because its red blood cells lack A, B, and Rh antigens, making them compatible with virtually all recipients.
What is O Negative (O-)?
500
Identify the cell below
What is a lymphocyte?
500
Identify the appropriate vessel, structure, or feature for letter B.
What is the left auricle?
500
Identify the vessel at "11"
