Question

research it! go to this link and research : https://view.genially.com/66bbe3abcfb9611ccbb67336 the url is case - sensitive. after you complete your research, answer these questions: 1. describe what happens to the oxygen level, muscle temperature, and blood flow during intense exercise. 2. what happens to muscle oxygen levels during intense exercise compared to being at rest? 3. think about what happens to blood flow during intense exercise and what happens to oxygen levels. why is blood flow during intense exercise important?

Explanation:

Step1: Oxygen level during intense exercise

During intense exercise, muscles consume oxygen at a higher rate. So, the oxygen - level in the body (especially in muscles) decreases as the demand for oxygen exceeds the supply rate initially.

Step2: Muscle temperature during intense exercise

Muscle contractions generate heat. As the intensity of exercise increases, more muscle contractions occur, leading to an increase in muscle temperature.

Step3: Blood flow during intense exercise

The body increases blood flow to the working muscles during intense exercise. This is to deliver more oxygen and nutrients to the muscles and remove waste products like carbon - dioxide.

Step4: Muscle oxygen levels comparison

At rest, muscle oxygen levels are relatively stable as the demand for oxygen is low. During intense exercise, muscle oxygen levels drop significantly because the muscles require a large amount of oxygen for energy production through cellular respiration.

Step5: Importance of blood flow during intense exercise

Blood flow is important during intense exercise because it supplies oxygen to the muscles for aerobic respiration, which is the main source of energy for muscle contractions. It also helps in removing metabolic waste products, such as lactic acid and carbon - dioxide, from the muscles, preventing fatigue and maintaining muscle function.

Answer:

1. Oxygen level decreases, muscle temperature increases, and blood flow to the muscles increases during intense exercise.
2. Muscle oxygen levels are much lower during intense exercise compared to when at rest.
3. Blood flow during intense exercise is important because it supplies oxygen for energy production in muscles and removes waste products, which helps maintain muscle function and prevent fatigue.
