The human excretory system is composed of organs, which excrete excretory products. These excretory products include urine, sweat, blood, etc. Urine is the basic excretory product of our body. In animals, the major excretory products produced are urea, ammonia, carbon dioxide, carbonic acid, urethrostomy fluid, etc. Plants produce cetrimide, which is an amino acid and is excreted through skin pores.
The human excretory system has two kidneys, which are in the abdomen on the left side. The renal tubule is a tube having a pair of hollow tubes through which sterile fluids are drained when the animal drinks. Kidney cells grow in the tubules. The function of the kidneys is to filter the wastes from the blood into the urine.
The role of the kidneys in the animals excretory system is similar to that in human. In both cases, the kidneys eliminate the wastes through filtration. In case of humans, however, the kidneys play a cardinal role in the elimination of waste products. The kidney is responsible for maintaining good health and leading a healthy life.
The nephron is the tubule of the kidney. The neurons are involved in the process of fluid removal. The kidney maintains a balance between water and waste products through the nephrons. In case of animals, the kidneys filter the wastes through the nephron. Waste products accumulated in the nephrons are eliminated through excretory products through the nephron.
The next in importance after the kidneys is the class 11 anatomy and physiology of animals. The classification of this anatomy and physiology of animals is based on the characteristics of the excretory system. The first five classes are class I, class II, class III, class IV, and class V. The characteristics of the excretory system in animals are described in detail by the class 11 biology and physiology excretory products and its elimination.
The kidney is one of the most important organs of the body. It is a large organ with a broad functional area. The kidneys mainly excretory products in the form of liquid and semi-solid wastes. The kidney secretes various kinds of wastes like urea, ammonia, oxalate, phosphate, and crystal salts which are excreted through the ureters and are used as an important metabolic product by all animal cells for their normal functioning. Other functions of the kidney in animal metabolism are production of hormones and regulating electrolytes.
The function and structure of human kidney are similar to that of animal kidney. Only difference is that human kidney has two different sections, the endocrine gland. Endocrine glands secrete hormones responsible for the growth and maintenance of human body. On the other hand, endocrine glands secrete neurotransmitters that are involved in transmitting nerve signals. It is observed that most kidney diseases occur due to accumulation of certain toxic wastes, resulting in accumulation of cellular debris in the forms of insoluble deposits, which inhibits the functioning of the excretory system and thus results in loss of minerals and other essential nutrients.
There are many products that can be used for the purpose of excretory products and its elimination. It includes dietary supplements, pharmaceutical products and drugs. Though dietary supplements and drugs are usually considered more effective, they are also quite expensive. Moreover, some products might have side effects, and it may not be applicable for some animals, so the administration of such products may also not be possible. Dietary supplements and drugs are also widely available, but these forms of products should be given with precaution to avoid the occurrence of any undesirable incident.
The excretory system in animals is mainly divided into three major functional units. These units are mainly dependent on the type of organ that they belong to. These units include renal tubule, ureters, and the entire renal tubule. Renal tubules and the entire kidney are connected through a thin urethra, which supplies urine and blood to the animal. Other than these units, some other important parts within the excretory system are the laparoscopic tract, the terminal horns of the kidney, the stomach, the hypochondrium, the erythroderma, the tunica vaginalis, the subserosal vena cava, the spleen, and the adrenals.
There are several biological processes involved in the function of an animal’s kidneys. First, there is the extraction of liquid wastes through the urethra. Second, the filtration of toxins in the blood and the assimilation of nutrition is done through the tubule. Thirdly, the utilization of the excretory product made of urea, uric acid, and albumin is carried out by the kidney.
There are several diseases and ailments that have their characteristic features in the functioning of the excretory system. Some examples are, hyperthyroidism, AIDS, chemotherapy, multiple sclerosis, pericardial mesothelioma, osteoporosis, and many others. So, it is very important to maintain the health of the excretory system through the appropriate diet, supplements, and regular workouts. So, next time you think of what you should eat or what kind of food supplements to take for your body, keep in mind that the kidneys are a major component in this process.
