How to Keep Excretory System Healthy
In the short-term, as the exercise level increases, the blood flow to the skin increases, and then the heat disappears through the pores. Prepaid cards not accepted. Your goal is required. I am a student I am a teacher. As ADH levels rise, the kidneys produce more concentrated urine, thus causing the level of sodium in the bloodstream to further drop. The excretory system traps wastes like urea and excess salts and expels them from the body.

How Does the Excretory System Respond to Physical Activity?

If that's not enough, physical activity may actually help stave off dementia. Scientists haven't fully solved this riddle, but many theorize this is due to the increased blood flow to the brain, which somehow prevents plaque from building up in the brain, a symptom connected to dementia. Exercise can have psychological benefits, as well.

In the long-term, some people may become addicted to exercise in a similar way that people become addicted to drugs or alcohol or even food. On the positive side, when one looks in the mirror and likes the results, exercise can result in improved self-image, self-confidence, and self-esteem. The average adult takes over 20, breaths each and every day. In the short-term, exercise increases the breathing which allows more oxygen to reach the lungs and the blood.

In the long-term, exercise keeps the respiratory system and the lungs clear and healthy and able to produce more oxygen. This means the lungs will operate at a more efficient level while having more lung capacity. In the long-term, exercise can help a person lose weight and maintain that weight loss. Much less stress is put on the ankles, knees, and other joints, lessening the chance of injury.

In the long-term, however, exercise can also wear down the cartilage between the knees and cause pain and discomfort. Obviously the risk of injury to the skeletal system is always there for the athlete during exercise.

Sprains involve injury to ligaments and strains to tendons. There are also joint dislocations and, in the worst cases, fractures, breaks, or even death. Most experts now believe that physical exercise can play a major part in the overall health of the human body and in preventing premature death. In this lesson we discussed the effects of physical activity on the human body and its major systems.

We discussed the circulatory, digestive, endocrine, excretory, immune, integumentary, muscular, nervous, respiratory, and skeletal systems. Then, we looked at both the long-term and short-term effects of exercise on these systems.

Effects of Physical Activity The majority of scientists now believe that the effects of physical activity are mostly good for the human body. Systems of the Human Body Before we discuss the effects of physical activity on the human body, it is imperative that first we identify the major systems of the human body.

Circulatory or Cardiovascular System Physical activity not only raises good HDL cholesterol but also reduces the dreaded triglycerides.

Digestive System When to eat and how much to eat are subjects of endless debate among experts. Endocrine System The endocrine system is composed of a series of glands that secrete hormones. Excretory System It's not the most pleasant or glamorous system to discuss, but the excretory system is responsible for the critical role of removing liquid and solid wastes from the human body.

Immune System Of all the human body systems, the effect of physical activity on the immune system seems to spark the most debate among experts and scientists. Want to learn more?

Muscular System In the short-term, exercise may cause muscle soreness and muscle fatigue.

Nervous System The nervous system is composed of the spine, the nerves, and the brain. Respiratory System The average adult takes over 20, breaths each and every day. Skeletal System In the long-term, exercise can help a person lose weight and maintain that weight loss.

Drink eight glasses of water each day to keep your excretory system nourished and functioning properly. Your skin is an important part of the excretory system. 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.

Exercise also provides a fresh, highly oxygenated blood supply to the major organs of the excretory system. Aim to get 30 to 60 minutes of exercise three to five times per week. Like all systems of the body, your excretory system needs a plentiful supply of vitamins, minerals and energy to regulate kidney and liver function and to keep all systems working properly.

This is best accomplished by eating a variety of nutrient-dense foods. Fruits, vegetables, legumes and whole grains are some of the most nutrient-rich foods you can give your body. Lean proteins and low-fat dairy can also provide essential nutrients to your diet. Avoid fast food, processed foods, junk food and empty calories to keep your excretory system working as it should.

Aside from being less nutrient dense, these foods typically contain additives and preservatives that your excretory system has to work hard to process. The more toxins you ingest, the bigger the workload your excretory system has to handle.

There are some parts of even healthy foods that the body cannot process and some byproducts of bodily function that occur naturally. Then there are the additional elements of waste your system must process. Some ways to avoid these excess toxins are to avoid drugs, alcohol and smoking. Be conscious of the lotions and body-care products you use.

In many cases, slathering these on have the same effect as ingesting them--they enter your blood stream and must be processed by the liver.
