In the immune system there are multiple functions happening to stop an infection or bacteria from taking over and getting the body sick. One of the most important features of this defense or system is the white blood cells. The White Blood Cells work to fight off any infection there is and have a memory function that remembers the disease to keep it away. 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 Cell Culture Human embryonic stem cells are pluripotent stem cells derived from the inner cell mass of the blastocyst‚ an early-stage embryo. To culture these stem cells under controlled environments‚ one first must have a growth medium. This growth medium is made with DMEM/F12‚ which is cell culture medium‚ a 20 percent Knockout Serum Replacement‚ 100 μM β-Mercaptoethanol‚ 1 percent non-essential Amino Acid‚ and a Basic Fibroblast Growth Factor. This medium is then changed out everyday

Plants capture the energy from the sun and converts it into food that is needed by all plants and animals (including us as humans). In this process the chemical reaction which is known as photosynthesis‚ it takes the sun’s energy and chlorophyll found in chloroplasts

Sickle Cell Disease Blood has been considered the essence of life for centuries‚ and our blood is a living tissue made up of liquid and solids. There are many diseases related to blood such as anemia which is the decrease in oxygen supply to tissue and causes hypoxia‚ thalassemia is the mutation in one or more globin gene of hemoglobin‚ etc. Therefore‚ one of blood disorders is the most common symptomatic hemoglobinopathy with the greatest prevalence in worldwide which is called sickle cell disease

Skeletal Muscle Cell There are millions of different types of cells in the world. They are located everywhere. Some are more known than others. The skeletal muscle cell was studied by many scientist but two important scientist are Alexander Mauro and Bernard Katz. They discovered a lot about thee skeletal muscle cell. The skeletal muscle cell is located everywhere in the body. Skeletal muscle cells are attached to bones by tendons as well in some areas the skin. Skeletal muscle cells are in the

A human body system A system of human body means a collective functional unit made by several organs in which the organs work in complete coordination with one another. Organs cannot work alone because their are certain needs of every organ that need to be fulfilled and the organ itself cannot fulfill those needs. So all organs of human body need the support of other organs to perform their functions and in this way an organ system is formed. Example of dependance of organs of a system on one
