SPRING 2018 1. Put the following in order of increasing complexity. (From the simplest to the most complex) 1. Hemoglobin 2. Heme 3.Erythrocyte 4. Oxygen 5. Aorta a. 1.2.3.4.5 b. 4.2.1.3.5. c. 3.2.4.1.5 d. 2.4.3.5.1. e. 4.3.2.5.1. ling systemic blood pressure requires moment to moment modifications of this most i determination of vascular resistance. a. Vessel diameter b. Vessel length . Number of WBC d. Amount of protein in plasma e. Weight of the individual 3. The capillaries structurally allow RBCs and large molecules to filter are known as found in the a. sinusoid, marrow b. sinusoid, liver c. fenestrated, kidney d: Continuous, kidney e. Continuous, lungs 4. The human immune response contains both Innate and Adaptive components. Thes as: a. Innate no memory, inflammation, antibody production b. Innate-memory, physical barriers, antibody production c. Adaptive no memory, inflammation, cell activation d. Adaptive memory, cell activation, antibody production 5. Which option correctly matches the blood vessel tunic to the correct tissue a. Tunica media - smooth muscle b. Tunica intima connective c. Tunica externa epithelial d. Tunica adventitia=nervous e. Tunica lumina smooth muscleExplanation / Answer
1. answer:b> 4.2.1.3.5.[ why this? O2 simple molecule-----> oxygen is attached to heme which complex than O2------> Heme with other structure forms hemoglobin------>hemoglobin is a part of erythrocyte, so erythrocyte is more complex than hemoglobin----> and then erythrocyte flows via the aorta, the aorta is functioning with all the previous complex things]
2. answer: A) vessel diameter
[ according to Hagen-poiseuille equation vascular resistance is inversely related to the 4th power of the radius of the blood vessel]
3.c) fenestrated, Kidney [ filtration is done by kidney where capillary is fenestrated]
4.d) adaptive = memory, cell activation, antibody production [ innate immunity is nonspecific and it is done by received antibody from mother, phagocyte, NK cell etc, but adaptive immunity is acquired via immunization so there are a memory cell, cell activation, and antibody prodcution]
5.a) Tunica media = smooth muscle [ tunica adventitia or externa is compsoed of collagen fibers and vasa vasorum, tunica intima is made endothelial cells, tunica externa and adventitia are same layer, tunica lumina/lamina is made of elastic tissue]
