What will your friend’s blood type be?Group of answer choicesType A or Type BType OType BType AFlag question: Question 5Question 51 ptsWhat happens in the body when an incorrect blood type is transfused into a blood transplant patient? E.g. Type A injected into a Type B person.Group of answer choicesThe recipient’s antibodies don’t recognize the antigens on the blood cells and begin to attack them, resulting in heavy clotting and perhaps death.The body will recognize foreign antigens on the blood cells and create new antibodies that will learn to tolerate the new blood type.The recipient’s antigens don’t recognize the antibodies on the blood cells and begin to attack them, resulting in heavy clotting and perhaps death.The recipient’s antibodies will immediately attack the blood cells EXCEPT in the case where the donor blood is Type O. Type O is the only kind of blood that can be donated.Flag question: Question 6Question 61 ptsWhich blood type is the universal donor? Which blood type is the universal recipient?Group of answer choicesType O; Type ABType O; Type BType O; Type OType AB; Type OFlag question: Question 7Question 71 ptsIn which tissues do blood cells release their oxygen to the surrounding tissues?Group of answer choicesThe lungsthe veinsThe aortaThe capillariesFlag question: Question 8Question 81 ptsTrue/False: All animals have a four-type blood system, similar to humans.Group of answer choicesTrueNo answer text provided.FalseNo answer text provided.Flag question: Question 9Question 91 ptsWhat is the positive (+) or negative (-) symbol in reference to when discussing blood types?Group of answer choicesThe Rhesus factor, which indicates presence or absence of the Rh antigen.The Rhesus factor, which indicates presence or absence of the Rh antibody.The Rhesus factor, which represents a special type of blood cell present in the blood.The Reactivity of Heart (Rh), which indicates susceptibility to blood transfusions.Flag question: Question 10Question 101 ptsWhat genetics phenomenon that we’ve learned about previously can be used to describe the AB blood type, in terms of dual expression of alleles?Group of answer choicesCo-dominance.True Dominance.Recessive alleles.Partial Dominance.Flag question: Question 11Question 111 ptsWhat is the oxygenation state of blood in the right and left side of the heart, respectively?Group of answer choicesright = oxygen rich ; left = oxygen depletedright = oxygen free ; left = some oxygenright = oxygen depleted ; left = oxygen richright = top half oxygen rich ; left = bottom half oxygen depletedFlag question: Question 12Question 121 ptsWhat is the name of the vein which delivers oxygen depleted blood to the heart?Group of answer choicesThe pulmonary arteriesthe Vena Cava (superior and inferior)The AortaThe pulmonary veinsFlag question: Question 13Question 131 ptsTrue or false: Veins ALWAYS carry oxygen depleted blood. Group of answer choicesNo answer text provided.No answer text provided.True.False.Flag question: Question 14Question 141 ptsWhich parts of the heart allow blood to flow in only one direction? How many of these parts are there in the heart?Group of answer choicesThe atria, 2.The valves, 4.The valves, 2.The ventricles, 2.Flag question: Question 15Question 151 ptsWhy do the ventricles have much thicker musculature than the atria?Group of answer choicesBecause the ventricals are the primary pumps that distribute blood throughout the entire body and must be strong.Because the ventricals only receive oxygen rich blood and must pump this to the body.Because the ventricals receive electrical impulses constantly and so must have more muscle tissue in order to recover in time.Because the ventricals only receive oxygen depleted blood and must pump this to the lungs.Flag question: Question 16Question 161 ptsWhat is the name of the valve that keeps blood from flowing backward into the left ventricle?Group of answer choicesthe tricuspid valve.The pulmonic valve.Aortic valve.The mitrial valve.Flag question: Question 17Question 171 ptsWhy are heart diagrams and drawings of veins and arteries often depicted as red and blue?Group of answer choicesBecause red represents oxygen-rich blood, and blue represents oxygen depleted blood. In reality there is no blue blood or veins, two-color visualization is just a learning tool.Because in the body, the blood cells turn blue when they are oxygen depleted.Because red represents oxygen depleted blood, and blue represents oxygen rich blood.Because the veins can turn a blue color, which can create a bluish appearance of blood.Flag question: Question 18Question 181 ptsWhat is the primary artery that distributes blood throughout the body?Group of answer choicesThe Vena Cava (inferior).The Vena Cava (superior)The aorta.The pulmonary arteries.Flag question: Question 19Question 191 ptsLet’s say you just heard a very complex riddle and used tons of brain power (and oxygen!) to come up with the answer. From which major vein or artery will this oxygen depleted blood reach the heart?Group of answer choicesThe right pulmonary artery.The Vena Cava (inferior).The right atrium.The Vena Cava (superior).Flag question: Question 20Question 201 ptsWhich of the anatomical features below do arteries have, that veins do not?Group of answer choicesan elastic tissue layer.endothelial cells.one way valves.a thin layer of smooth muscle cells
