what is stem cells.
Stem cells are cells with the potential to develop into many different types of cells in the body. They serve as a repair system for the body. There are two main types of stem cells: embryonic stem cells and adultstem cells

How do neurons help the body?
eurotransmitters can excite or inhibit neurons (nerve cells). ... Acetylcholine and norepinephrine are excitatory neurotransmitters while dopamine, serotonin, and GABA are inhibitory. Each neurotransmitter can directly or indirectly influenceneurons in a specific portion of the brain, thereby affecting behavior.

What are the three functions of white blood cells?
- Monocytes. They have a longer lifespan than many white blood cells and help to break down bacteria.
- Lymphocytes. They create antibodies to defend against bacteria, viruses, and other potentially harmful invaders.
- Neutrophils. ...
- Basophils. ...
- Eosinoph

What do Stem Cells do to your body
In some parts of the body, such as the gut and bone marrow, stem cells regularly divide to produce new body tissues for maintenance and repair. Stem cells arepresent inside different types of tissue. Scientists have found stem cells in tissues, including: the brain

Why are Nerve cell important in the human body
Neurons are nerve cells, or cells found in the nervous system. These are specialized cells designed to stimulate other cells in the body in order to communicate. Neurons are excitable, which means they function by using electrical stimulation.Apr 23, 2015

Is low white blood count serious
Underlying causes for a low white blood cell count can range from benign disorders, such as vitamin deficiencies, to more serious blood diseases, such as leukemia or lymphoma. A truly low white blood cell count also puts you at higher risk for infections — typically bacterial infections.Feb 4, 2011

What does it mean when you have low red blood cells?
A low red blood count or anemia can cause feelings of fatigue and weakness. When people have a lower red blood count than normal, their body has to work overtime toget enough oxygen to the cells. This can leave a person feeling drained. ... Red blood cells are continuously produced in the bone marrow

Where do Stem Cells come from
Embryonic stem cells. These stem cells come from embryos that are three to five days old. At this stage, an embryo is called a blastocyst and has about 150 cells. These are pluripotent (ploo-RIP-uh-tunt) stem cells, meaning they

What is the purpose of nerve cells
Motor neurons transmit electrical impulses from the brain to the rest of the body and are connected to sensory neurons by specialized cells called association neurons.The human body contains millions of nerve cells that transmit electrical impulses almost instantaneously.

What causes your red blood cells to be low?
Diseases and conditions that cause your body to produce fewer red blood cells than normal include: Aplastic anemia. Cancer. Certain medications, such as anti-retroviral drugs for HIV infection and chemotherapy drugs for cancer and other conditions.

What are Stem Cells used for
t is transplanted routinely to treat a variety of blood and bone marrow diseases, blood cancers, and immune disorders. More recently, stem cells from the blood stream (called peripheral blood stem cells) and umbilical cord stem cells have been used to treat some of the same blood-based diseases.

What is a nervous tissue give its function?
Nervous tissue is composed of three main parts: nerves, the spinal cord and the brain. The primary function of nervous tissue is to receive stimuli and send the impulse to the spinal cord and brain. The brain sends back a response to the muscles via the n

Why are Stem Cells important
Stem cells differ from other kinds of cells in the body. All stem cells—regardless of their source—have three general properties: they are capable of dividing and renewing themselves for long periods; they are unspecialized; and they can give rise to specialized cell types.

What does the nervous tissue do in the heart?
The autonomic nervous system (ANS) regulates the functions of as the heart, stomach and intestines. ... The heart is innervated by parasympathetic and sympathetic fibers. The medulla is the primary site in the brain for regulating sympathetic and parasympathetic outflow to the heart and blood vessels.

What kills white blood cells?
Low White Blood Cell Count. White blood cells are produced by your bone marrow to help your body fight infection. If you have fewer than normal white blood cells, you have a higher risk of getting an infection. When you have a low white blood cell count, your immune system isn't working as well as it should.Jan 16, 2018
