March 26‚ 2013 Lecture -The function of the eye is to convert photons of light into action potentials (nerve impulses). -The inner layer is a nervous tunic (made out of nerve cells)=retina. -Refraction: Bends light. -The purpose of the cornea and the lens is to take an object and focus every little detail of the object on the retina on the back of the lens. Upside down and backwards. -When light goes through medias‚ it bends. -Lens are suspended by ligaments behind the pupil. Suspensory ligaments

What is research? Thinking like a scientist From the article‚ I found that there are many ways to gain knowledge‚ some are better than others. The most important and reliable method is gaining knowledge via science and involving a merger of rationalism and empiricism at the same time. This way is a logistic way. In this way‚ hypotheses are testable. What’s more‚ we can merge rationalism and empiricism to adjust and reevaluate our position. Scientific research has three basic goals: to

sometimes other body parts. It is caused by a blockage in the vessels of the lymphatic system. Those infected with the disease often spend their lives disable and in tremendous pain. In the following pages‚ I will discuss the exact causes of the disease and its symptoms. Also‚ I will discuss what measures can be taken to treat and prevent the disease. Elephantiasis is a disease that affects the lymphatic system. In the lymphatic system‚ a white fluid called‚ lymph‚ travels through tiny vessels to the lymph

What is lymphedema? Lymphedema occurs when lymphatic fluid builds up in the soft tissues of your body‚ usually in an arm or leg. The lymphatic system consists of lymph vessels and lymph nodes that run through your body. Lymph vessels collect a fluid that is made up of protein‚ water‚ fats‚ and wastes from the cells of the body. Lymph vessels carry this fluid to your lymph nodes. Lymph nodes filter waste materials and foreign products‚ then return the fluid to your blood. If your vessels or nodes
