(BIOS 255 Week 7 Virtual Lab)
Part 1: Complete Labster “Cardio-respiratory Physiology: How can seals dive so deep for so long?” As you complete the lab, have the lab report ready to record data. The theory section of the lab is a useful resource.
Part 2: Complete the lab report.
Respiratory Physiology Lab Report
- Compare the diving depths and oxygen stores and aerobic dive limits: (5 points)
- What is the main difference between seals and humans regarding oxygen stores? (1 point) b. Where is the greatest proportion of oxygen stored in humans? (1 point)
- Do seals show approximately the same factorial increase in oxygen consumption as humans during diving? (1 point)
- How did the rate of oxygen consumption during diving change between a seal diving for 12 mins vs diving for 30 mins? (1 point)
- Explain why some lactate accumulated in the 30 min dive vs none in the 12 min dive. (2 points)
- How does the seal’s heart respond to diving? (1 point)
- What do the heart rate and consumption rate patterns suggest about seal diving? (1 point)
- You’ve learned so much about the physiology of diving, and major adaptations of seals that enhance their oxygen storage capacity and ability to dive. Which of the following is an INCORRECT statement regarding seal adaptations? (1 point)
- How does the respiratory system complement the circulatory system? (1 point)
