A diagram, picture or illustration and information about the kind of cells related to that system. For example, if you do the circulatory system, you should have a picture of different blood cells, if you do the nervous system, you should have a picture of a nerve cell.

• Human Organ Systems Course - The main function of the cornea and lens is to focus images on the retina. The iris constricts to protect our retinas from bright light and to aid in focus. It dilates to enhance vision in dim illumination. The very central visual field is optimized for perception of fine detail, color and depth. The peripheral visual field is primarily concerned with motion perception. Two parallel pathways comprise the functional architecture of the sensory visual system; one pathway is for 'object vision or what is it?' — color, texture, form, stereopsis and contrast, the other is for perception of transients — motion and flickering lights to tell us 'where is it?' Damage to nerve fibers at different locations in the sensory visual system results in predictable and anatomically localizing visual deficits.

• You Have to Have a System - The human body is like a complex organization that has an important job to get done on a tight deadline. In order to get everything done perfectly and on time, it has to use a system. Actually, the human body uses many systems that work side by side.

• Life Cycle - Human Body (3A) - The human body is composed of different systems that have specific tasks to complete. The Respiratory System contains organs, that working together will allow us to breathe. The respiratory system has lungs, diaphragm, and esophagus. However, the heart is also part of the respiratory as it pumps blood into the lungs to get oxygenated. It is important to emphasize that we operate as a well-tuned machine, with most of our parts having more than one function. When one part of the body fails, it sometimes triggers other organs to fail also. Below are descriptions that may be useful when the students do their activity.

diseases

• Dysfunctional Uterine Bleeding - Menstruation is a normal, predictable event for most women. In the United States, the average age of the first menstrual period is 12.8 years.1 After an initial 4- or 5-year period of adjustment, the normal menstrual cycle averages:

• Neuromuscular Diseases in the MDA Program - the characteristics of a disease; the usual age of onset, progression and inheritance type; a comprehensive list of materials on this Web site about the disease.

• what is acne? - Acne (acne vulgaris) is a condition involving blemishes (or lesions) of the skin that affects most people at some stage of their life.

• what is Rhinitis - Rhinitis describes the lining of the nose when it becomes inflamed (red and swollen). People with this condition usually complain of an itchy, stuffy, or drippy nose; a scratchy throat; and coughing.

• what is Diabetes - Diabetes (Diabetes Mellitus) is a severe, life-threatening condition in which the body loses its ability to turn glucose (sugar) from food into usable energy. It is sometimes, mistakenly, called 'Sugar' Diabetes.

• Pneumonia - Pneumonia is a serious infection or inflammation of your lungs. The air sacs in the lungs fill with pus and other liquid. Oxygen has trouble reaching your blood. If there is too little oxygen in your blood, your body cells can't work properly. Because of this and spreading infection through the body pneumonia can cause death.

• what is panic disorder - PD is a brain disorder that manifests itself in many different ways, involving chronic recurrent unexpected panic attacks.

• what is HIV - HIV (Human Immunodeficiency Virus) is a virus that can lead to the development of AIDS (Acquired Immunodeficiency Syndrome). It can be found in the body fluids of an infected person.

• what is heart attack - A Heart Attack is usually described as a myocardial infarction. It is the result of an obstruction of blood flow in one of the branches of the two coronary arteries which supply the heart muscle with blood.

• what is a stroke - A Stroke occurs when part of the brain is suddenly damaged or destroyed. It is a result of the interruption of the blood supply to brain tissue because of a narrowing or blocking of an artery, or physical damage to the brain by internal or external bleeding

• what is breast cancer - Breast Cancer is the second most common cancer (after lung cancer) affecting women in the United States. Although much more common in women, men can also develop this disease.

• what is congestive heart failure - Congestive Heart Failure (CHF) is a condition where the heart is unable to supply the vital organs of the body with enough blood (carrying nutrition and oxygen) to meet the body's demands

• what is Otitis Media - Acute Otitis Media is inflammation of the lining (mucous membrane) of the middle ear, often accompanied by an accumulation of fluid (effusion) The condition involves the area behind the eardrum, containing three delicate bones (ossicles), which transmit sound from the eardrum to the inner ear

• what is atherosclerosis - Hardening of the Arteries (Atherosclerosis) is a process where part of the lining in an artery thickens and the tube narrows, causing a reduction in blood flow. It is sometimes referred to as

• what is Gastroesophageal Reflux Disease - Gastroesophageal Reflux Disease (GERD) is the back flow of the stomach contents into the esophagus (the tube that connects the mouth to the stomach) with or without esophageal inflammation.

• Babesiosis - Babesiosis is a rare, severe and sometimes fatal tick-borne disease caused by various types of Babesia, a microscopic parasite that infects red blood cells. In New York State, the causative parasite is Babesia microti.

• Chickenpox - Chickenpox is a highly communicable disease caused by the varicella virus, a member of the herpes virus family. In temperate climates, chickenpox occurs most frequently in winter and early spring.

• Cholera - Cholera is a bacterial disease that affects the intestinal tract. It is caused by a germ called Vibrio cholerae. Although only a few cases are recognized in the United States each year, epidemic levels of cholera have recently been reported in parts of Central and South America.

• Cryptosporidiosis - Cryptosporidiosis is an intestinal illness caused by a microscopic parasite called Cryptosporidium. Approximately 400-500 cases are reported in New York State each year.

• Cyclospora Infection - Cyclospora is a microscopic parasite that can affect the intestinal tract and cause diarrhea. It is an uncommon disease in the United States and is occasionally associated with foreign travel.

• Cytomegalovirus - CMV is a common virus that infects most people at some time during their lives but rarely causes obvious illness. It is a member of the herpes virus family. Other members of the herpes virus family cause chickenpox, infectious mononucleosis, fever blisters (herpes I) and genital herpes (herpes II) . Like other herpes viruses, CMV infection can become dormant for a while and may reactivate at a later time. The virus is carried by people and is not associated with food, water or animals.

• Ehrlichiosis - Ehrlichiosis is a tick-borne disease which can be caused by either of two different Ehrlichia bacteria. Human Monocytic Ehrlichiosis (HME) is caused by Ehrlichia chaffeensis, which is transmitted by the lone-star tick (Amblyomma americanum). Human Granulocytic Ehrlichiosis (HGE) is caused by an Ehrlichia equi-like bacteria that is transmitted by the deer tick (Ixodes scapularis). In New York State, most cases of ehrlichiosis have been reported on Long Island and in the lower Hudson Valley.

• E. coli O157: H7 Infection - E. coli are bacteria that normally live in the intestines of humans and animals. Although, most strains of this bacteria are harmless, several are known to produce toxins that can cause diarrhea. One particular E. coli strain called 0157: H7 can cause severe diarrhea and kidney damage.

• Fifth Disease - Fifth disease is a viral infection which often affects red blood cells. It is caused by a human parvovirus (B19) . For many years, fifth disease was viewed as an unimportant rash illness of children. Recently, studies have shown that the virus may be responsible for serious complications in certain individuals.

• Giardiasis - Giardiasis is an intestinal illness caused by a microscopic parasite called Giardia lamblia. It is a fairly common cause of diarrheal illness and it is estimated that several thousand cases occur in upstate New York each year. Cases may occur sporadically or in clusters or outbreaks.
