Question
Chapter 21.5, Problem 19BYGO
Summary Introduction
To analyze:
The blood vessels that change after birth
Introduction:
The development of blood vessels, both in the embryo and later in life, is called angiogenesis. The first trace of embryonic angiogenesis appears at 13 to 15 days of gestation. At this time, the embryo is a three-layered disc of mesoderm, ectoderm, and endoderm, attached to the uterus by an embryonic stalk and associated with three membranes.

There was no sign of the median cubital vein. You then moved to the cephalic vein, selecting a site and cleaning it. After it dried, you inserted the needle using an evacuated tube system. Blood dripped very slowly into the tube; at this rate, you thought the collection would take over 5 minutes, and the sample would likely still be inadequate. You explained this to your patient, removed the needle, and inserted it further up the vein—still almost no flow. You then reapplied the tourniquet, chose a site in the basilic vein and tried again. This time there was no blood—you must have missed the vein. What did you do wrong? What should you do now? Answer in 10 sentences of what did you do wrong?

Please encircle your answer and in each case, explain what is incorrect. When the muscular walls of the blood vessels all over a woman’s body contract, the space inside the vessels becomes larger so her blood pressure falls. Explanation: Hypertension during pregnancy reduces the blood supply from the endometrial arteries in the mother’s uterus to the fetus via the placenta. Explanation: Hypertension reduces the amount of amniotic fluid surrounding the fetus, because the blood flow to the baby’s kidneys is reduced so it makes less urine. Explanation: Fetal growth is not restricted in a pregnant woman with hypertension. Explanation:arrow_forward
