How well can the circulatory system supply oxygen to working muscles during excises?

oxygen is breathed into the lungs where 'gaseous exchange' takes place, this transfers the oxygen to the blood supply (circulatory system) which already contains various substances ie. food etc. Oxygen is taken via the blood capilary network to the muscle cells 'mitchocondria' where 'airobic resperation' takes place, this involves the food being broken down using the oxygen, releasing energy to the cells and producing carbon dioxide and water as byproducts.

How can you get abs muscles during the summer?
You can indeed get defined ab muscles during the summer months. This simply requires working out and eating good foods.
What develops during gastrulation and will later develop into bone muscle and circulatory structures?
The middle layer is formed during the gastrulation. This layer develops into muscles, bones and blood vessels.
How are substances transported around our body when exercising?
Same as at rest, but slower, all via the circulatory system. The distribution is different too - during exercise the muscles that are actually working (using oxygen) get a much higher blood flow than those tissues at lower metabolic states.
Why do skeletal muscles tire quickly during execise?
Many reasons: Putting too much exertions on weak muscles working out or lifting wrong heavier: therefore more strain on muscles
What muscles are working during squats?
quads (narrow squats) & gluteals & hamstrings (wide-positioned squats)
During exercise a lot more blood is distributed to the working muscles how is this achived?
heart pumps faster.
Why does blood flow quicker during exercise?
Because the heart beats faster during exercise to ensure that oxygen gets to the working muscles.
What principle focuses on working the core muscles first and then works other muscles?
Core exercise is important, because it help strengths the core muscles. Core muscle training will also strengthen other muscles during the training.
What is the number one rule about muscles?
they grow not in the gym exercising but when you take rest during sleep after exercising (working out in the gym)
Is it right to practice with dumbbells during aerobic exercise until the muscles start to shiver or does the shivering of the muscles mean that you are working good?
it most likely means that yu are overworking your body
When muscles are active cells use nutrients and oxygen at a higher rate and produce waste chemicals and heat more rapidly Describe how the interaction of two or more body systems help to maintain?
During periods of high muscle activity muscles need more oxygen requiring the respiratory system to work harder (a person breaths harder) to take in more oxygen. This oxygen is taken to the muscle via the circulatory system. During periods of high muscle activity heart rate increases which causes the circulatory system to deliver the oxygen and nutrients to the muscles at a faster rate. Since the muscles are working hard they also produce waste chemicals and heat more rapidly. The circulatory system deals with this problem by releasing the heat through veins near the skin. The increased rate of the circulatory system also allows waste chemicals such as carbon dioxide to leave the body at a faster rate because it is delivered back to the lungs at a increased rate. Once at the lungs the carbon dioxide is traded for oxygen.
What does cardiorespotaory fitness measure?
It measures the capacity of the heart, lungs, and blood to transport oxygen to the working muscles, and measures the utilization of oxygen by the muscles during exercise.
