In this activity, students begin a sequencing activity with familiar items letters written on cards.
When dynamic exercise begins, oxygen uptake by the lungs quickly increases.
After several minutes,oxygen uptake usually remains relatively stable (steady state) at each intensity of exercise.
Exercise can elicit cardiovascular abnormalities not present at rest and can be used to assess function of the cardiovascular system.
Isotonic (dynamic) exercise, defined as muscular contraction of large muscle groups resulting in movement, primarily provides a volume load to the left ventricle, and thecardiovascular response is proportional to the degree of the exercise.
Work on only a small part of the cross-sections geologic history then find the next higher unconformity and work on the events between the two unconformities.
You will join the unconformities by linking them with periods of uplift and erosion followed by ocean rising and deposition of sedimentary rocks (if the rocks are marine in origin.
Blood flow is redistributed so that more blood goes to where it’s needed most during exercise – your muscles. What role do they play in meeting the demands of exercise?
As you might have guessed, your breathing rate goes up as exercise intensity increases, so you can supply more oxygen to your lungs.
In turn, this oxygen attaches to red blood vessels inside your blood vessels so it can travel from your lungs to your muscles.
You also breathe more deeply as your body’s oxygen requirements rise during exercise.
Sequencing the rock layers will show students how paleontologists use fossils to give relative dates to rock strata.
