How Does the Excretory System Respond to Physical Activity?
Urine contains mostly water, but also contains salts and nitrogen-containing molecules. Present to your audience Start remote presentation. The surfaces of healthy alveoli are springy and flexible. This means that people would not die if they stopped smoking. There are actually two parts to respiration, external respiration and internal respiration. It is characterized by a cough that produces phlegm, or mucus. The ureters are muscular ducts that propel urine from the kidneys to the urinary bladder.

Sweating removes water and salts from your body together with a small amount of urea. As the level of sodium in your bloodstream drops, ADH secretion also falls, and your kidneys produce urine that is more dilute.

After a certain point, the hypothalamus begins to boost the release of ADH from the pituitary gland to conserve water as much as possible. As ADH levels rise, the kidneys produce more concentrated urine, thus causing the level of sodium in the bloodstream to further drop.

One of the ways your body excretes toxins is through sweat. When you exercise, you sweat more and you also need more water. Sweat is made up of some of the processes of respiration, such as dead cells, according to the Franklin Institute. Aim to get 30 to 60 minutes of exercise three to five times per week.

Features The excretory system traps wastes like urea and excess salts and expels them from the body. Exhalation occurs by contracting these muscles. In order to inhale, you expand these muscles.

The more you can expand these muscles, the more fresh oxygenated air flows in. The more you contract them, the more stale and toxic air is being expelled. In order to experience the expansion and contraction of the breathing muscles, try this simple exercise: Sit up straight, do not move any muscle and try to pull air in through your nose. The only way to inhale is through the expansion of muscles. When these muscles expand, a low-pressure situation is created and air rushes in automatically.

Now sit up straight again and try to exhale through your nose. Nothing will happen unless you contract your muscles. The more you can contract, the more you can expel.

But you can never get all the air out of the lungs, the lungs cannot be collapsed, unless of course, you are run over by a truck. The respiratory system is nourished through proper breathing which is the basis of physical and mental well being. At all levels of your practice, you will find that all these systems are being purified, toned and strengthened.

The Sampoorna approach to Yoga exercise, which consists of breathing exercises, strengthening and warming up exercises, Asanas, and deep relaxation, helps you to gain endurance, strength and flexibility while restoring balance in the body. Almost everyone has some kind of imbalance in their body. By virtue of being right-handed or left-handed, you work one side of the body more than the other.

But if you observe certain basic points in your asana practice, it helps you to realign the body and restore symmetry and balance. In your Asana practice, you should work towards gaining strength, endurance and balance, not only flexibility.

A common misconception is that a person who is flexible is a good Hatha yogi. But in reality, that person may be developing weakness in their body. If you only stretch the muscles in one direction, you inevitably develop weakness, which is undesirable. Instead, you should strive for symmetry and balance. For example, if you find that your backward-bending postures are weak, you should practice those more.

Most people like to do the Asanas that they can perform easily and neglect those which are more difficult for them to perform; in the process of doing that, they develop greater imbalance. If your approach to Hatha yoga is correct, you can restore symmetry and balance in your body.

When you perform asanas, your mind should be focused on the area of tension. For example, in forward bending, your attention should be on feeling the stretch in the hamstring muscles and the nervous system. Focus on the area of tension and stress and breathe into it.

In doing so, you release the stress and tension in that area. The stiffness, tension and stress accumulates there from lack of exercise and lack of toning.

If you learn about the mechanics of the body and how to release stress while maintaining a proper posture, it helps to ease the tensions. Wherever you find stress, you will find more circulation. But if your body is toxic, it is bringing more toxins to that area. That is where proper diet comes in.

If your colon is blocked and you have constant constipation, you will find tension in your neck. The moment you get rid of the constipation, you feel released there. These are very simple things that you will experience in your practice of yoga. The medication that is prescribed only treats the effect, neglecting the cause. When you practice yoga, you need to practice with some understanding.

If the understanding is not there, you will not get the desirable result. You have to understand what the purpose of each yoga posture is. Once you know the purpose, whatever you do will help you to get the desirable result.

If you understand these basic things, you will be able to adapt the postures to any situation. You do not need to teach a special class for obese or elderly people.

If you understand the principle, you can modify, adapt and adjust the postures for anyone. Take, for instance, the spinal twist. What is the purpose of the spinal twist? It is to twist the spine. You may get other benefits from it but the purpose is to twist the spine. In order to twist the spine, you have to keep it erect. If it is not straight and you try to twist it, it will not happen.

You will find that people go into all kinds of gymnastics in spinal twist which mostly defeats the purpose and serves to boost their Ego. The posture should be adjusted in relationship to the flexibility of the person and how much freedom they have. If a person is very obese and very stiff, it does not mean that they cannot do spinal twist.

Whatever they can do to twist the spine is sufficient. They can simply keep their legs straight. The position of the hands is only to aid the twisting of the spine.

As long as they keep their attention on the spine and continue to breathe as they twist the spine, they are getting the benefits of spinal twist. Later on, as they lose weight and gain flexibility, they may be able to cross their foot over, but that should not compromise the vertical position of the spine.

A person who is flexible may be able to go into all kinds of variations, but that does not mean they are getting more benefits than the person who has the legs straight. So once the spine is erect, you can twist it. In my years of involvement in the field of Hatha Yoga, I noticed that people who depend on props in their Yoga practice, never seem to advance. While some may argue that if you want to learn how to ride a bike, you need training wheels, I would say that the training wheels in this case, namely the props, create limitations.

I have seen people pulling on straps or using blocks as props. In the case of a strap, if they are only pulling on the strap, it will take much longer to improve as the body is not really pulled on.

On the other hand, people who pull and stretch their bodies, improve in a very short time. The same goes for using blocks as props. Take the triangle pose as an example: You impose a limitation on yourself. You will not go any further than that.

The other person will be moving and stretching, and in a short time their hand will be down on the floor. You can observe the practice of headstand as another example. People always run to the wall when you tell them to do headstand. People who have used that wall for years develop dependence on the wall and cannot move away from it. Another person who has never done headstand before, if I teach them step by step how to do it, in a week they are doing headstand without the wall.

Look at the benefits. The person who is using the wall is developing dependence on the wall. They are not going step by step so they are not developing the muscles to prepare them for headstand. They are also not developing confidence because they continue with the fear that they are going to fall.

All of these things are negating the benefits of yoga! Yoga should give you confidence and independence. It should help you to develop focus, concentration and awareness of your body. All this is negated if you just jump on the wall doing headstand. These people will never advance to a regular headstand with variations.

Moving onto variations in the headstand is similar to teaching a baby to run. If the baby is not even crawling yet, will you be able to teach it to run? How does the baby learn to run? They crawl, creep, walk and finally they run.

It is a natural progression. The idea of which variation to do in headstand is irrelevant until you are ready. First you learn how to do dolphin in the Sampoorna Yoga Level 1 Class. You measure the hands and bring the elbows under the shoulders. Then you interlace the fingers, raise the hips, come up and do dolphin.

It strengthens the shoulders and also brings the awareness to the elbows pressing down on the floor. That is the secret of the headstand. So you go step by step. Once you go step by step and experience the headstand effortlessly, from there on you do whatever you want.

There are gymnasts that can do almost anything. For example, there are people who can do headstand without using their hands up in the air on a swing that is swinging.
