Chapter 16, Problem 39RA
Summary Introduction
To review:
1. The physiological advantage of the fetus having a different form of hemoglobin.
2. The physiological mechanism responsible for the fetus having a high hemoglobin concentration and its relation with physiological neonatal jaundice.
Introduction:
The transportation of oxygen in the blood is carried out by the hemoglobin. Four oxygen atoms bind with one hemoglobin molecule in order to get transported. The transportation of oxygen with hemoglobin is governed by various factors. Hemoglobin binds and supplies oxygen by loading and unloading reactions.

- A developing fetus gets oxygen from its mothers blood. Fetal capillaries run through pools of maternal blood in an organ called the placenta. As fetal blood runs through these capillaries, it exchanges substances with the maternal blood around the capillary. The hemoglobin made by a fetus is different than that made after birth. Fetal hemoglobin binds oxygen more strongly at low oxygen levels than normal hemoglobin. How would fetal hemoglobins somewhat higher affinity for oxygen benefit the fetus?arrow_forwardWhy is Fetal Hemoglobin Essential for survival of Placental animals?arrow_forwardThe PO2 of placental blood is about 40 mmHg.

- Hemoglobin will bind oxygen and release CO2 in places where there is a higher concentration of O2, lower concentration of CO2, lower temperature and lower acidity (as it is in lungs) and will do the reverse – release oxygen and bind CO2 - in places where there is a lower concentration of O2, higher concentration of CO2, higher temperature and higher acidity (as it is in working muscles). True False While white blood cells never leave the circulation, red blood cells regularly leave it and travel by lymphatic system or find home in other tissues, e.g., lymph nodes, spleen, etc. True False Blood clotting (coagulation) is a complex process involving many factors and it exhibits positive feedback loops: many of the factors also stimulate production of their own precursors.
