Simple answer: They don't.
Long answer: Cells do not transform into organs. They make up organs. Complex cellular signals are given by Homeobox genes during embryonic development, positioning individual cells to multiply, specialize, and arrange themselves properly before birth.
The human body is made of organs. Certain organs work together to form systems. We each have a respiratory and a Circulatory system, Digestive system and Excretory System.
The excretory system usually consist of organs which produce waste. Examples are: The Kidneys (which filters our blood and sends the waste material to the bladder) The Bladder (which expels urine) The Digestive system also has a say since: The Large Intestine (Deals with our excrement/feces) The Liver (which produces the urea 'Not' the kidneys this is a popular misconception). And also indirectly: The Lungs (which expel carbon dioxide) The organs however that belong to this system are: * http://www.answers.com/topic/urinary-system ** http://www.answers.com/topic/kidney ** http://www.answers.com/topic/nephron ** urine * http://www.answers.com/topic/large-intestine-2 * http://www.answers.com/topic/lung ** carbon-dioxide * http://www.answers.com/topic/skin ** perspiration-2 * http://www.answers.com/topic/liver ** bile * http://www.answers.com/topic/spleen * ** Worn-out Red Blood Cells * http://www.answers.com/topic/lymph-node ** Foreign Cells * http://www.answers.com/topic/malpighian-tubule-system (http://www.answers.com/topic/arthropod excretory system) ** menstrual-cycle Follow the hyperlinks for organs you don't recognise
An organism is a living thing, such as a human or an oak tree. Organ systems make up the organism to achieve the processes it requires. Examples are the respiratory and circulatory systems. Organs are individual parts of the organ systems, e.g. the kidney is part of the excretory system, and the heart is part of the circulatory system. Tissues make up the organs, and are masses of cells of the same type. Muscle tissue makes up part of many organs. Cells are the basic units of life, for instance muscle cells make muscle tissue, and nerve cells make nerve tissue.
1 pore cell, 1 duct cell, 1 canal cell, and a fused pair of gland cells
Well, a group of cells form tissues, a group of tissues form an organ, and a group of organs form an organ system. An organ system is a group of organs that work together to complete a certain task like the digestive system or the urinary system.
Planaria ,which lives in fresh water ,has two strands of branching excretory tubes that open to the outside of the body through excretory pores .The simple tubular excretory is called protonephridium,Which is a network of closed tubules without internal openings.Tubular system is spread through out the body.Located along the tubulesare bulb like Flame cells
Endocrine Cells
Filtered by the kidney, liver, spleen, (am I missing any?) and enter the excretory system
Excretory system gets rid of waste. Respiratory system supplies blood cells with oxygen.
The digestive system produces nutrients that are required for the cells all over the body to survive. The nutrients are brought to the cells by the circulatory system, and the wastes produced by the excretory system are taken away from the cells.
The excretory system.
The cells found in the excretory system are: one pore cell, one duct cell, one canal cell and a pair of gland cells.
The human body is made of organs. Certain organs work together to form systems. We each have a respiratory and a Circulatory system, Digestive system and Excretory System.
Yes, look cancer is basically the overgrowth or uncontrolled growth of cells through division beyond normal limits , invasion that intrudes upon and destroys adjacent tissues, and sometimes metastasis, which spreads the cells to other locations in the body via lymph or blood. So therefore, cancer can affect any part of the body which has cells. As even the excretory organs, such as kidney, have cells, they can also be hit by cancer. Examples of excretory system organs cancers are: Kidney cancers, etc.
No, the excretory system removes wastes!
By Excretory System
Circulatory and excretory depends on the cells XD
