Concept explainers
To describe:
The effect of iron deficiency in humans which is responsible for carrying oxygen in red blood cells.
Introduction:
Trace elements or minerals are those elements that are required by the body of an organism in small amount. These include iron, manganese, copper, molybdenum, zinc, boron, chlorine, nickel, iodine, selenium, chromium, silicon, vanadium, fluoride, lead cadmium, mercury, arsenic, aluminum. They are present in small amount but are important for the growth and development of body.
Some of these trace elements are used as a catalyst for enzymatic reactions. Trace elements are toxic if it is consumed in higher quantity. Trace elements are of two types essential and non essential. Essential trace elements are those which are required for the growth and development while non essential elements are those that are present in the body but are not required for growth and development.

- At high altitudes, _______. a. nitrogen bubbles out of the blood b. hemoglobin has fewer oxygen-binding sites c. there are fewer O2 molecules per unit volume of air than at low altitudes d. there is more carbon monoxide than at sea levelarrow_forwardWatch this video (http://openstaxcollege.org/l/oxyblood) to see the transport of oxygen from the lungs to the tissues. Why is oxygenated blood bright red, whereas deoxygenated blood tends to be more of a purple color?arrow_forwardWhich of the following factors play a role in the oxygen-hemoglobin saturation, dissociation curve? temperature pH BPG all of the abovearrow_forward
- Oxygen enters the blood in the lungs because relative to alveolar air: a. the CO2 concentration in the blood is high. b. the CO2 concentration in the blood is low. c. the O2 concentration in the blood is high. d. the O2 concentration in the blood is low. e. the process is independent of gas concentrations in the blood.arrow_forwardPredict Hb's affinity for oxygen at different conditions in the blood (in the lungs, in the tissues, pH changes, low & high oxygen levels, 2,3-BPG, fetal Hb)? I need help answering this questionarrow_forwardWhen ventilation is not sufficient, which of the following occurs? The capillary constricts. The capillary dilates. The partial pressure of oxygen in the affected alveolus increases. The bronchioles dilate.arrow_forward
- Q2) The world standard for tiny particles in air with the thickness of more than 2.5 micrometer is 50 μm/ m3 , if risk factor for these particles to be 0.85 .what microgram of these particle will be penetrated to lungs in each breathing containing 0.5 Litter of air ?..arrow_forward21. Which of the following best describes the Bohr Effect? Group of answer choices The regulation of oxygen binding in hemoglobin by carbon dioxide and hydrogen ions. Refers to the atomic orbitals of oxygen. The binding of oxygen to hemoglobin is cooperative. The effect of 2,3-BPG upon hemoglobin or myoglobin.arrow_forwardWhat is an advantage of water over air as a respiratory medium? What are two key advantages of air over water as a respiratory medium?arrow_forward
- 21. A 20% increase in which of the following would be most effective in achieving the greatest increase in oxygen content of pulmonary capillary blood in a perfectly homogeneous lung inhaling air at sea level? A) Cardiac output B) Hemoglobin concentration C) Hemoglobin P50 D) Inspired O2 concentration E) Ventilation Please explain the reasoning for each choice. I understand that other choices says its D but please tell me why it's not the other.arrow_forwardA molecule of hemoglobin ________. is shaped like a biconcave disk packed almost entirely with iron contains four glycoprotein units studded with oxygen consists of four globin proteins, each bound to a molecule of heme can carry up to 120 molecules of oxygenarrow_forward10. Certain phenomena can be observed in a person running. What causes the runner's breathing rate to increase. a) The cells produce more CO2. b) The cells make more urea. c) The cells release more energy. d) The cells have a greater need for glucose.arrow_forward
