Question:I am doing a 7th grade project and I need to make a poster about the excratory system , I only need BASIC ANSERS. I need the purpose and function of three diferent systems of excretion and the names of the key parts or organs of the system . Also its interaction with other body dystems and the disseases and disorders that can be gotton in the excratory system and any other usefull information . PLEASE THIS WILL HELP SO MUCH!!!

Answers:Anus / rectum - you do poo poos. IE you defaecate Urethra / ureta - you do wee wees. IE you urinate. Thems the basics. Of course, before the anus, you have the bowel, a reservoir for the feces before it is eliminated. The whole digestive system can be included as a part of this excretory system. With the other, the main parts are the kidneys, which filter out the waste and the bladder - the reservoir for storage prior to elimination. This only deals with waste. Other excretions occure within the body but that is another story.


Answers:Which part of the excretory system are you referring to? If you're referring to the urinary excretion system involving the kidneys then there is active transport in the control of water and salt in the blood and urine. There are two different hormones which are released, ADH and aldetosterone. ADH causes more water to be released into the blood from the loop of henle in the kidney, aldetosterone causes the sodium ions to enter the blood stream followed by water through osmosis. These hormones control salt concentration and water concentration in blood and the way this is controlled is active transport.

Question:i'm only in seventh grade so please use english that I might be able to understand. Its a project that my partners and i are supposed to do. Does any one know any activities i could do with the digestive and excretory? Were supposed to teach the class. Please don't right anything ridiculous. Were also supposed to write a "mini" plan book. Thanks!! :)

Answers:Usually when we think of the excretory system, we think of feces. However, urination is also part of the extretory process. One think we did in our anatomy and physiology lab might work for you. Nobody was allower to pee before coming to class. Then one group drank like a quart of tap water. Another group drank like a cup of very very salty water. Then every 1/2 hour we had to pee into a cup and measure how much we peed. The people who drank plain water peed their brain out. The people who drank salt water peed only a little bit and it came down to almost nothing on the 4th pee. The reason is that "where sodium is, water follows" - kind of an old saying. Those of us who has a lot of sodium retained in their systems, also reabsorbed water from kidney tubules (which ultimately sends urine to collection tubules to be urinated out.). Also, for the people that drank plain water, the color of their urine got lighter and less fragrant over time. The salt water people's uring got darker and had a stronger odor over time. This isn't totally about the digestive system but the water goes through it and into the bloodstream. Might work. It was really kind of fun. We recorded our results (amount peed and color) on the board at the front of the class and then compared results. Each group and 4 people in it, so you had 4 people in the plain water group reporting their individual results and the same for the salt water people. The results are very interesting. Good luck!

Excretory System :Check us out at www.tutorvista.com Excretory system is a passive biological system that removes excess, unnecessary or dangerous materials from an organism, so as to help maintain homeostasis within the organism and prevent damage to the body. It is responsible for the elimination of the waste products of metabolism as well as other liquid and gaseous wastes. As most healthy functioning organs produce metabolic and other wastes, the entire organism depends on the function of the system; however, only the organs specifically for the excretion process are considered a part of the excretory system. As it involves several functions that are only superficially related, it is not usually used in more formal classifications of anatomy or function. Removes metabolic and liquid toxin wastes as well as excess water from the organism. Within each kidney are an estimated one million microscopic nephrons. Filtering of the blood takes place within these areas. Each nephron contains a cluster of capillaries called a glomerulus. A cup-shaped sac called a bowmans capsule surrounds each glomerolus. The blood that flows through the glomerulus is under great pressure. This causes glomerulus, water, glucose and urea to enter the bowmans capsule. White blood cells, red blood cells and proteins remains in the blood. As the blood continues through the blood vessels, it winds around the renal tubala. During this time, reabsorption occurs.

Functions of the Lymphatic System Part 1 :Lymphatic System Functions : www.balancedhealthtoday.com Lymphatic Detoxification : www.balancedhealthtoday.com Fluid and Protein Balance As blood moves through the arteries and veins, 10% of the fluid filtered by the capillaries, along with vital proteins, becomes trapped in the tissues of the body. This loss of this fluid (approximately 1-2 liters/day) would rapidly become life threatening if the lymphatic system did not properly function. The lymphatic system collects this fluid and returns it to the circulatory system. Immunity and Spread of Infection The lymphatic system plays an integral role in the immune functions of the body. It is the first line of defense against disease. This network of vessels and nodes transports and filters lymph fluid containing antibodies and lymphocytes (good) and bacteria (bad). The body's first contact with these invaders signals the lymphatics, calling upon this system to orchestrate the way the infection-fighting cells prevent illness and diseases from invading microorganisms. Digestion Lymph vessels in the lining of the gastrointestinal tract absorb fats from food. A malfunction of this part of the lymphatic system can result in serious malnutrition. The lymphatic system also impacts diseases such as excessive obesity caused by abnormal fat and carbohydrate metabolism.
