To analyze:
The reason that athletes often move to elevations higher than those, at which they will compete, several months before a competition.
Introduction:
Red blood cells (RBCs) play an important role in the body of an organism. They carry oxygen from lungs to different tissues. RBC is produced in red bone marrow and each has a lifespan of 120 days. The level of hemoglobin or number of RBCs determines the oxygen transport to the tissues. Hemoglobin is a globular protein, which contains two alpha chains, two beta chains, and a nonprotein pigment called heme. There are four heme units in one hemoglobin molecule and each heme unit can hold an iron, which binds to an oxygen molecule.

- What is the major mechanism that results in acclimatization?arrow_forwardcaffeine is also diuretic, which means it increases the movement of water through the kidneys into the urine. Why would this potentially offset its value to a distance athlete?arrow_forwardWhy does evaporation have a cooling effect?arrow_forward
- How might the anatomy and physiology of persons who were born and raised at very high altitudes be different from those who were born and raised in the lowlands and have only recently become acclimated to high elevations?arrow_forwardWhat is the effect of adding water to the body?arrow_forwardIf calcium cannot be returned to the SR quickly after a muscle contraction, how would this affect muscle function?arrow_forward
- A runner drinks three cups of caffeinated coffee to prevent becoming dehydrated while completing a marathon. Do you think this practice will help prevent dehydration or promote dehydration? Explain your answerarrow_forwardWhat does saturation refer to?arrow_forwardExplain why some world-class athletes train at high elevation in order to improve performance in competitions held at low elevations. Explain the effects of high elevation and the regulatory mechanisms behind these effectsarrow_forward
- Why does sweating cause both a decrease in extracellular volume andan increase in body fluid osmolarity?arrow_forwardHow does any type of shock cause oliguria? Question 2 options: a) By stimulating chemoreceptors and osmoreceptors b) By decreasing perfusion to the kidneys c) By decreasing production of antidiuretic hormone d) By decreasing parasympathetic nervous system stimulationarrow_forward
