What is it? Sickle cell anemia is a type of blood disorder that can be inherited from parents. This is when red blood cells that are meant to carry oxygen around the body become deformed. Normal red blood cells are round and disc shaped‚ however‚ when they become sickle red blood cells‚ the deform and change shape into a crescent-like shape or sickle shape. The sickle cells have a shorter life-span than a healthy red blood cell and are not replaced as quickly as normal; this leads to a shortage

A leukocyte‚ which is the formal name for white blood cells‚ protects the body in various ways from getting sick. The red bone marrow’s stem cells‚ which are called hemocytoblasts‚ are the source of creation for almost all of the white blood cells. Five types of white blood are carried through the blood

phone has become the favored communication hub for the majority of American teens. 1 Cell-phone texting has become the preferred channel of basic communication between teens and their friends and cell calling is a close second. Some 75% of 12-17 year-olds now own cell phones‚ up from 45% in 2004. Those phones have become indispensable tools in teen communication patterns. Fully 72% of all teens – or 88% of teen cell phone users — are text-messagers.2 That is a sharp rise from the 51% of teens who were

Sickle Cell Anemia Sickle cell anemia is an inherited blood disorder‚ identified by the sickle shape of red blood cells which carry less oxygen and break easily‚ causing anemia. The sickling trait‚ the less serious form‚ occurs from the inheritance of only one parent; however‚ both parents must exhibit the disease in order for full symptoms to take place. It is caused by an error in the gene that tells the body how to make hemoglobin. The disorder is usually found in people of African descent

After reading the “‘Bubble baby’ stem cell” paper I have come to the conclusion that stem cell research is an excellent thing. The reason why I think that is if we never do research and create a cure for “Bubble baby disease” then we will continue to lose babies. But‚ if we risk a few lives of babies for research in the long run it will save millions if not billions of lives. In this essay I will give three reasons on why I think stem cell research is a great thing. “Bubble baby disease.” In my

Impact of Technology on Cell Theory Technology has had a profound impact on the development of cell theory‚ allowing scientists to view the components of organisms on an unprecedentedly small scale. Before the creation of microscopes‚ misconceptions about how organisms were originated arose. The idea of spontaneous generation‚ a theory held for nearly two millennia‚ proposed that organisms originated from inorganic matter. The lack of technology impeded on the development of cell theory‚ until the creation

major types of cells that can be found in the skin. The 4 major types of cells that are found in the human body are keratinocytes‚ melanocytes‚ epidermal dendritic (Langerhans)‚ and the tactile (Merkel) cells. The keratinocytes‚ which are epithelia cells‚ are the most abundant cells in human body and dominate the epidermis. These cells contain keratin and work together to form layers known as thick skin‚ which consists of 5 layers‚ and thin skin‚ which consists of 4 layers. These cells are in the stratum
