1. EQ: How does the structure and function of my immune system keep me healthy?

The structure and function of our immune systems is a great help for our body to keep all of us healthy. Our immune system has a specific structure that it should maintain. There are also organs that play a major part for the health of our immune system. These organs are called lymphoid organs because of the lymphocytes that inhabit that area. (white blood cells) Bone marrow is also one of the key elements for the immune system, this is where all of our blood cells are being made along with the white blood cells. With the help of the bone marrow, white blood cells are constantly traveling throughout our bodies using the blood cells for help. Another structure that is important for our immune system is lymphoid tissue. Lymphoid tissue acts as a gateway into our bodies that help to prevent incoming germs.

Describe the function of the immune system:

The function of the immune system is it helps play a vital part of our everyday lives. It helps protect our bodies where ever we go. Our immune systems help defend our bodies against germs and microorganisms. The immune system is made up of various special cells, tissues, organs and proteins. This special system does an amazing job of keeping our bodies healthy and in good shape from different diseases and infections.

Explain how the skin functions as a defense against disease:

Our skin functions as a daily defense for our bodies against disease because of skin and mucous membranes. The skin is a massive organ and it protects everything inside our bodies such as our muscles, bones and organs. Our skin protects us from bacteria, parasites, viruses and pathogens that try to interfere with this specific system. Our epidermis which is our outermost layer of skin plays a major part in defense. Every cell that is in our skin is called a keratinocyte, and if they are intact (connected together) no type of germ or bacteria can pass through. How mucous helps play a part of defense against disease is there are layers of this type of epithelial tissue lining the edges of our respiratory tracts and gastrointestinal tracts. These tracts are home to goblet cells. These specific cells produce a sticky mucous that can trap dust and incoming infections. (microbes) Our skin also is the home to langerhans cells. When they sense that a bad piece of bacteria or infection they make sure to send a chemical signal to our body which attracts our white blood cells to kill the infection off.

Distinguish between a specific and nonspecific response:

Nonspecific responses in our immune system work by a wide variety of invaders. This means that they focus not on one type of cell but by different kinds. As for specific responses in our immune systems, these are asked to help when nonspecific responses are not enough to fight of the invading infection.
