Cell Importance why is this type of cell important to a healthy body? Self Check - Research Organizer I have described the structure, functions and purposes of specialized cells.
I have included clear and accurate information for each of the categories. I organized my information clearly in a chart. Self Check - Biological Drawing I have identified the parts of cells using a microscope image. I have drawn a clear and accurate representation of the cell using the rules of biological drawing.
Submit Your Work. Super Cells. It's a Bird, It's a Plane, It's Super Cell! Most importantly, think about why this cell would be useful in the body. I have related my Super Cell to the digestive, respiratory or circulatory systems. I have responded to a classmate's post describing how our Super Cells can work together, based on their structure and function. I have used appropriate scientific terminology to clearly describe specialized cells. Join The Discussion.
I have described the structure, functions and purposes of specialized cells. I have clearly stated the function and structure of my Super Cell. Each type of cell in the human body is specially equipped for its role. Cells of the digestive system , for instance, are vastly different in structure and function from cells of the skeletal system. Cells of the body depend on each other to keep the body functioning as a unit.
There are hundreds of types of cells, but the following are the 11 most common. Stem cells are unique in that they originate as unspecialized cells and have the ability to develop into specialized cells that can be used to build specific organs or tissues. Stem cells can divide and replicate many times in order to replenish and repair tissue. In the field of stem cell research , scientists take advantage of the renewal properties of these structures by utilizing them to generate cells for tissue repair, organ transplantation, and for the treatment of disease.
Bones are a type of mineralized connective tissue that comprise a major component of the skeletal system. Bones are made up of a matrix of collagen and calcium phosphate minerals. There are three primary types of bone cells in the body: osteoclasts, osteoblasts, and osteocytes. Osteoclasts are large cells that decompose bone for resorption and assimilation while they heal.
Osteoblasts regulate bone mineralization and produce osteoid, an organic substance of the bone matrix, which mineralizes to form bone.
Osteoblasts mature to form osteocytes. Osteocytes aid in the formation of bone and help maintain calcium balance. From transporting oxygen throughout the body to fighting infection, blood cell activity is vital to life.
Blood cells are produced by bone marrow. The three major types of cells in the blood are red blood cells , white blood cells , and platelets. Red blood cells determine blood type and are responsible for transporting oxygen. White blood cells are immune system cells that destroy pathogens and provide immunity. Platelets help clot blood to prevent excessive blood loss due to broken or damaged blood vessels. Muscle cells form muscle tissue , which enables all bodily movement.
The three types of muscle cells are skeletal, cardiac, and smooth. Skeletal muscle tissue attaches to bones to facilitates voluntary movement. These muscle cells are covered by connective tissue, which protects and supports muscle fiber bundles. Digging Deeper: Germs and Disease. Digging Deeper: Milk and Immunity. Submitted By:.

Your body has over different kinds of cells, from blood cells to bone cells to brain cells. The number they arrived at was 30 trillion.
You may have read that bacterial cells in the human body outnumber human cells 10 to 1. The primary source for that ratio dates back to the s, when American microbiologists used a series of assumptions to calculate the number of bacteria inside the intestinal tract.
New data show that the number of bacterial cells inside a human body is around 38 trillion. This turns out to be much closer to the estimated 30 trillion human cells in the body. There are three types of blood cells: red blood cells, white blood cells, and platelets. Red blood cells RBCs are by far the most abundant type of cell in the human body, accounting for over 80 percent of all cells.
Adult humans have somewhere around 25 trillion RBCs in their body, on average. Women usually have fewer RBCs than men, while people living at higher altitudes will usually have more. There are also about million platelets and another 45 million lymphocytes a type of white blood cell in the body, based on recent calculations.
There are roughly billion cells in the average male brain according to new research, including about 86 billion neurons. Neurons are cells that help transmit signals throughout the brain. There are also 85 billion other cells in the brain, called glial cells, that help support the neurons. The lifespan of each of the types of cells varies considerably, so not every type of cell is produced at an equal rate.
A good start is to look at the number of RBCs that are produced each day, as RBCs are the most abundant type of cell in the body. RBCs live for about days, at which point they are removed from circulation by macrophages in the spleen and liver. At the same time, specialized stem cells are replacing the dead red blood cells at roughly the same rate. The average body makes about 2 to 3 million red blood cells every second, or about to billion red blood cells per day. Most, but not all, cells in the body will eventually die and need to be replaced.
Fortunately, a healthy human body is capable of maintaining a precise balance between the number of cells produced and the number of cells that die.
