well digestive system is made up of tissue, ie., start from mouth to rectum. The food passes through, oesophagus,colon,stomach,etc., where the food get digested by the acids,agenst and enzymes secreted in the stomach/colon.
For the absorption of nutrients in the colon is done by villus.
one pore cell, one duct cell, one canal cell, and a fused pair of gland cells
Juxtaglomerular cells Visceral and parietal epithelium The above are some specialized cells of urinary system. The cells of the distal tubule become taller and form a structure known as the MACULA DENSA. and this is the specialized tissue in urinary system.
a specialized excretory cell found in the simplest freshwater invertebrates
Endocrine Cells
Excretory system gets rid of waste. Respiratory system supplies blood cells with oxygen.
i think it has somthing to do about the type of cell needs another cell to live off otherwise the specialized cell wont exist.actually, im pretty sure it has to do with something that it depends on other systems, for example, the circulation system needs the excretory system for proper circulation of the blood.
The excretory system.
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 cells found in the excretory system are: one pore cell, one duct cell, one canal cell and a pair of gland cells.
The human excretory system is responsible for the elimination of wastes produced by the body and is made up of four distinct cell types. These are one pore cell, one duct cell, one canal cell, and a fused pair of gland cells.
specialized cells
3.cells in the nervous system are different in structure from cells in the circulatory system and they carry out different specialized functions
No, the excretory system removes wastes!
