Construct each statement regarding ABO blood typing and possible adverse reactions from transfusions by clicking and dragging the labels to the correct location.
A patient with blood type O who receives blood type A blood will have a transfusion reaction because this patient produces both anti-A and anti-B agglutinins which will agglutinate with the type A agglutinogens. The best blood to receive is the blood with the same blood type as your own blood type; thus, if you are blood type B, then your preferred donor type would be blood type B. A patient with blood type A would not be able to receive blood from blood types B and AB because if he did, he would produce anti-B agglutinins in response, which would cause agglutination of his blood. A patient who is blood type AB received blood from a type O person. Because the type O blood has neither A nor B antigens, the patient will not produce antibodies against this transfused blood.
Which of the following statements best describes what you would expect to happen if a transfusion recipient had blood type 0 and a donor had blood type AB?
Agglutination would occur as the recipient's antibodies bind to the donors antigens
Why is type O blood called the universal donor?
Because type O red blood cells contain neither antigen A nor antigen B, so they can be transfused into most recipients of any blood type, without being attacked by antibodies

D
Blood type __________ is sometimes considered the universal donor within the ABO blood group.
O

AB
Construct the statements in the paragraph regarding the Rh factor by clicking and dragging the labels to the correct location.
If an Rh-negative woman is pregnant carrying an Rh-positive fetus, the mother might obtain some RBCs from the fetus during the birth process or during a miscarriage. As a result, the mother would begin producing anti-D antibodies, creating complications for the second and future pregnancies. This condition is known as hemolytic disease of the fetus and newborn. This condition can be prevented with the proper administration of RhoGAM, which prevents the mother from producing anti-Dantibodies.
Which of the following blood types would represent a compatible donor for a person with blood type O?
O
Anti-D serum can be mixed with a person's blood to check for the presence of
Rh antigens
Hemolytic disease of the newborn could be of concern when an
Rh-positive fetus and an Rh-negative mother condition occur.
If you mixed a person's red blood cells with anti-B antibodies, and the red blood cells agglutinated, what could you conclude?
That the person's red blood cell membranes contain antigen B
Name the missing artery in the sequence by clicking and dragging the label to the correct location in each statement.
Brachiocephalic trunk, right subclavian artery, right axillary artery. Ascending aorta, aortic arch, descending thoracic aorta Abdominal aorta, superior mesenteric artery, ascending colon (right side of large intestine) Brachiocephalic trunk, right common carotid artery, right external carotid artery Axillary artery, brachial artery, radial artery Common iliac artery, external iliac artery, femoral artery Pulmonary trunk, pulmonary arteries, lungs
Construct accurate statements regarding the major arteries of the body by clicking and dragging the labels to the correct location.
In humans, there are three branches off of the aortic arch. The first branch is the brachiocephalic artery, the second branch is the left common carotid, and the third branch is the left subclavian artery. The main artery of the pulmonary circuit is the pulmonary trunk, which delivers deoxygenated blood to the lungs; the aorta is the main artery of the systemic circuit, delivering oxygenated blood to the body. The cerebral arterial circle, or circle of Willis creates an arterial anastomosis of blood vessels around the pituitary gland and optic chiasm to allow for alternative routes of blood supply to parts of the brain. The radial artery in the wrist or the common carotid artery in the neck is often used to take pulse, and in the arm, the brachial artery is often where blood pressure is taken. The superior mesenteric artery delivers blood to most of the intestines, while the inferior mesenteric artery has a smaller diameter and supplies the distal end of the large intestine.
Complete each statement regarding the hepatic portal circulation by clicking and dragging the labels to the correct location.
The azygos vein receives blood that is drained from veins within the thoracic cavity and wall, and blood is then emptied into the superior vena cava. The hepatic veins drain the liver, the suprarenal veins drain the adrenal gland, and the renal veins drain the kidneys. All three of these veins empty into the inferior vena cava. The hepatic portal system receives all of the blood that drains from the digestive tract in the abdomen, as well as the pancreas, gallbladder, and spleen; thus, it transports nutrient-rich blood to the liver before being distributed to the rest of the body. Given the blood that is emptied into capillaries from the hepatic portal vein, the liver utilizes nutrients for storage or synthesis, such as storing glucose as glycogen or synthesizing plasma proteins from amino acids. The liver also receives substances that may require detoxification, like medicines or alcohol, and it may receive pathogens like bacteria, which it will destroy.
Select all of the following that result in a transfusion reaction which could kill a person.
