What is the group of organs that work together?

You mean like a system? Digestive system is stomach, intestines, liver, etc. Immune system & others. Not 100% clear on what you want.

it is called a tissue, now a number of tissues working together is an organ

Cell, tissue, organ, system, body. Wow, this is 4th grade?\ncells organize and develop into tissues and tissues organize and develop into organs ...\n\nDO your own homework.

overall system that's working with the heart. Cardio - heart, vascular- blood vessels.

organ. The others actually are organs, while 'organ' is the name of the category they fall into.

Common animal (including human) organs include the heart, lungs, brain, eye, stomach, spleen, pancreas, kidneys, liver, intestines, skin, uterus, and bladder.\n\nBlood vessels exist in varying calibers:\n\nArteries \nAorta (the largest artery, carries blood out of the heart) \nBranches of the aorta, such as the carotid artery, the subclavian artery, the celiac trunk, the mesenteric arteries, the renal artery and the ileac artery. \nArterioles \nCapillaries (the smallest blood vessels) \nVenules \nVeins \nLarge collecting vessels, such as the subclavian vein, the jugular vein, the renal vein and the iliac vein. \nVenae cavae (the 2 largest veins, carry blood into the heart)

Skin, lungs, and liver.

The urinary system entails the kidneys(2 normally), the bladder, 2 ureters(tubes from kidneys to bladder), and the urethra (tube from bladder to opening in the body).\n\nLook in any anatomy and physiology book or yahoo health.

cell-tissue-organ-organ systems-organism (population)\nTissues are a group of specialized cells that perform a function. Organs are groups of specialized tissues that perform an even more complex function. Organ systems are groups of organs that perform a function in a series of complex, yet related steps. An organism is a body with  several organ systems necessary to maintain homeostasis. This can be extended to population which is several organisms existing together to survive (think food webs).\n\nUnicellular organisms do not have specialized cells. They have only one cell to perform all the functions it needs.

False, its the other way round.\nSingle celled orgarnisms have only one cell. this cell has different components that help it become multi-funtional. this means that its single cell are not specialised. for example. an Amoeaba which is a single celled organism has a nuclei which it uses for its metabolic processes, its mitochondria for energy, its cell wall for movement. so this one cell of an amoeba can perform different functions.\n\nmulti cellular ogarnisms have different cells that have been specialised for different purposes. e.g respiratory cells are for metabolic processes, growth cells are for growth, digestive cells are for digestion. \n\nthe digestive cells in a multicellular organisn come together to form digestive tissues. the digestive tissues will come together to form a digestive organ, different digestive organs will form the digestive system. different systems form the body.\n\nthanks. chaoo

Hmm Many great websites on biology have you looked any up? Start there does your text book have any resources for online help? Try that!! Cell = Tissue = Organ?

In biology, an organ (Latin: organum, "instrument, tool") is a group of tissues that perform a specific function or group of functions. Usually there is a main tissue and sporadic tissues. The main tissue is the one that is unique for the specific organ. For example, main tissue in the heart is the myocardium, while sporadic are the nervous, blood, connective etc. (Wikipedia.org)\n\nIn zootomy and dermatology, skin is an organ of the integumentary system made up of multiple layers of epithelial tissues that guard underlying muscles and organs. As the interface with the surroundings, it plays the most important role in protecting against pathogens. Its other main functions are insulation and temperature regulation, sensation and vitamin D and B synthesis. Skin is considered one of the most important parts of the body.(Wikipedia.org)\n\nPretty much the skin is considered an organ because it is a group of tissues speciallizing in a certain task / tasks. For example the skin regulates temperature by using the sweat glands to produce sweat - sweat evaporates and cools the body.

The heart is what pumps blood throughout the body, keeping all organs functioning. Blood flows to the body through arteries and blood flows back to the heart through veins. Its all one big system - the circulatory system.
