The knee joint is the largest joint in the human body and is made of two joints one is the tibiofemoral joint and the other is the patellofemoral joint. The knee joint allows various movements such as running, walking, and kicking. The kicking of a football involves the straightening of the knee, which leads to contraction of the muscles of the thigh. The quadriceps is a group of four individual muscles that includes vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris that are involved in extension of the knee.

Normal dive (for diving humans) normal breathing dive normal breathing Oz level CO2 level urgent need to breathe Oz blackout zone high CO2 triggers breathing 6. This diagram shows rates of oxygen depletion and carbon dioxide accumulation in the blood in relation to the levels needed to maintain consciousness and trigger the urgent need to breathe in diving humans. How might the location and slope of the O₂ line differ for diving marine mammals such as whales and dolphins? • How might the location and slope of the CO₂ line differ for diving marine mammals such as whales and dolphins? • • Draw in predicted lines for O2 and CO2, based on your reasoning above. How might the location of the Urgent Need to Breathe line and the O2 Blackout Zone line differ for diving marine mammals? What physiological mechanisms account for each of these differences, resulting in the ability of marine mammals to stay submerged for long periods of time?
