Exploring The Kangaroo Excretory System

The amino acids that are not immediately required are broken down in the liver to make urea; this urea is carried in the bloodstream to the kidneys for elimination of waste.

* Thermoregulation: The thermoregulation of the skin is carried out with the help of evaporation of the sweat and regulation of the blood flow to the dermis.

The liver has many roles in the body that associate it with many systems. For example, it acts as a digestive organ by secreting bile for the breakdown of fat (Copstead, 2010). The liver also removes bilirubin from the blood, temporarily stores blood and synthesizes the blood clotting factors (Copstead, 2010). Other functions of the liver are; removing toxins from the blood, metabolizing both sex hormones and steroid hormones. Any damage to the liver can in turn disrupt any of these processes and functions that it performs.

Exocrine glands, the liver and the kidneys remove toxins. A toxin is a biological poison. Some toxins are known to be stored in fat cells so it could be true that the more fat we have in our body the more toxic our body may become.

6. Evaporation evaporation of body water from the surface of the skin and the lining of the mucous membranes is a major source of heat reduction. Fluids are excessively secreted through sweat glands. This is stimulated in response to sympathetic neural activity and depends on a favorable temperature difference and the humidity of the air. Electrolytes

Its main function is to produce and eliminate urine as a means of maintaining stable concentrations of salt, acids, and other electrolytes as well as to rid the body of toxic metabolic wastes for homeostasis. The kidneys produce the urine while the rest of the urinary system is what carries the urine out of the body. The ureters are a pair of tubes that carry the urine from the kidneys to the bladder by gravity and peristalsis of smooth muscle. The bladder stores the urine until the urine can be passed. When the bladder contracts, the urine enters the urethra, which is the tube that takes the urine from the bladder to the outside.

The renal system also known as the urinary systems purpose is to eliminate wastes from the body, regulate blood pressure, and regulate blood pH.

The digestive and excretory systems help the body with the wonderful task of food. The digestive system is composed of the stomach, mouth, liver, pancreas, and the large and small intestine. It digests food and provides the

The western grey kangaroo, Macropus fuliginosus, who is also referred to as a black-faced kangaroo, belongs to the macropod family. This particular species of kangaroo is one of the largest macropods in Australia. They are a commonly found across almost the entire southern part of Australia. This species thrives in open woodland and forest, grassland, and can even be found throughout the outskirts of major cities.

The renal system in the body pertains to the kidneys. The kidneys are the eliminators of waste in the body and collects the ions and elements that that body needs. There are two kidneys, one on each side of the middle to lower back. At

The excretory system in the narrowest sense of the term is the urinary system. The urinary system consists of the kidneys, ureters, bladder and urethra.

The abdominal cavity which contains the stomach, most of the large intestine, the small intestine, the gallbladder, spleen, kidney and liver. The small intestine is very important and its job is to digest food and also take nutrients from food to help give back to the body. The gallbladder is a small storage organ also needed in digestion and holds bile products produced by the liver until needed for digesting fatty foods. The kidney is also vital because it helps aid in essential processes such as regulating blood pressure. The liver is very vital and performs multiple critical functions to keep the body pure of toxins and harmful substances. Without a healthy liver, a person cannot survive. Then the pelvic cavity which will contain also portions of the large intestine, reproductive organs, and the urinary bladder. The large intestine is also known for helping during digestion by taking undigested food and absorbing as much water as it can and expels the waste. The reproductive organs play a vital role in the survival of our species. Lastly, the urinary bladder functions as a storage vessel. It is one of the most elastic organs and is able to increase its volume

The liver’s complex biochemical process of detoxification is a two phase process, converting the byproducts of metabolism and toxins to render them into safer substance. Phase one, an enzymatic process, involves approximately 100 enzymes in the cytochrome P450 system. In Phase one, the chemical reaction known as biotransformation changes the toxin in to a less toxic, water-soluble substance to allow it to be safely excreted through the kidneys or colon. Enzymes do this through oxidation, the loss of electrons, or reduction, the gain of elections. Most of the time, the enzymatic reactions in Phase one decrease the toxicity of the substance, however, a more toxic intermediate substance may be produced, this is known as bioactivation.

The Liver is the body's largest gland, weighing about three to four pounds. It is located beneath the diaphragm in the right upper quadrant (RUQ) of the abdominal cavity. Without the liver, our bodies would be poisoned and unfit for us to do anything at all. It is a metabolically active organ responsible for many vital life functions. The primary functions of the liver are: Bile productions and excretion. Excretion of bilirubin, cholesterol, hormones, and drugs. Metabolism of fats, proteins, and carbohydrates. Enzyme activation. Storage of glycogen, vitamins, and minerals. Synthesis of plasma proteins, such as albumin, and clotting factors. And blood detoxification and purification.

Biotransformation involves the way in which the organism copes with potentially dangerous compounds found. They detoxification systems will try to eliminate poisonous food substances as well as drug molecules because they act as toxic agents to the body (Doweiko, 2009). Biotransformation is generally carried out in the liver although some tissues might also be involved in this process as well (Doweiko, 2009). The way the human digestive tract works is that it is designed not to allow any chemical to that has been absorbed to pass into circulation until it is first filtered through the liver (Doweiko, 2009). The liver acts as a kind of water purifier when it comes to the body. The bad substances are filtered out so that the body can keep most of the good substances.
