Biology : Excretory System Quiz

Your body regulates excretion in response to changes in its environment. The excretory system traps wastes like urea and excess salts and expels them from the body. In the process, it helps preserve a vital balance in the level of salts and fluids in the blood. A portion of your brain called the hypothalamus regulates excretion by producing anti-diuretic hormone ADH , which acts to reduce the amount of water removed from the blood by the kidneys and thereby to reduce the rate of excretion.

When you exercise, you may begin to sweat as your body tries to keep down its temperature. 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. As you continue to exercise, your body loses more water. 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. Try going to a sauna for an hour a couple of times a week. This works well for people who are disabled and cannot work out. The sauna will help with your sweat glands by opening them up. Breathing exercises will greatly help your lungs.

Take deep breaths throughout the day. Also, try blowing up a balloon or a beach ball. Laughing and singing more also can keep your lungs healthier. Keep your liver healthy by lying on your left side and gently hitting it quickly with your fist.

Start off by doing 20 strikes and gradually work up to as many as you can each day. Eat a proper, nutritious diet. Stay away from foods that contain pesticides, hormones and antibiotics. Also try to steer clear of fatty, oily foods. Your kidneys have to filter out all of these things.

Try to eat more fruits, vegetables, whole grains, nuts, beans and soy. Stay away from drugs, alcohol and tobacco. Also try to use over-the-counter medications as sparingly as you can. Never drink alcohol while you are taking medicine.
