The bones of the chest — namely the rib cage and spine — protect vital organs from injury, and also provide structural support for the body. The rib cage is one of the body's best defenses against injury from impact. Flexible yet strong, the rib cage protects major vital organs such as the heart, lungs, and liver.

Why are the kidneys important? Your kidneys remove wastes and extra fluid from your body. Your kidneys also remove acid that is produced by the cells of your body and maintain a healthy balance of water, salts, and minerals—such as sodium, calcium, phosphorus, and potassium—in your blood.

Your lungs are part of the respiratory system, a group of organs and tissues that work together to help you breathe. The respiratory system's main job is to move fresh air into your body while removing waste gases.

Lesson Summary Your skin is the biggest organ of your body, and it's an external organ because it's located on the outside of the body. Other organs include your brain, lungs, heart, liver, stomach, intestines, pancreas, and kidneys, and they're called internal organs because they're located on the inside of your body.

The vital parts of a cell are called "organelles." Among the most important are the nucleus, vacuoles, and mitochondria, all of which are enclosed within the cell membrane and immersed in cytoplasm. Each organelle performs a specific task that helps keep the cell alive.

Every cell in your body contains organelles (structures that have specific functions). Just like organs in the body, each organelle contributes in its own way to helping the cell function well as a whole. The nucleus, mitochondria and chloroplasts are all organelles. Some organelles are found only in some cell types.

Humans—and other complex multicellular organisms—have systems of organs that work together, carrying out processes that keep us alive. ... Cells make up tissues, tissues make up organs, and organs make up organ systems. The function of an organ system depends on the integrated activity of its organs.

Organs that can be donated after death are the heart, liver, kidneys, lungs, pancreas and small intestines. Tissues include corneas, skin, veins, heart valves, tendons, ligaments and bones.

By donating your organs and tissue after you die, you can save or improve as many as 75 lives. Many families say that knowing their loved one helped save or improve other lives helped them cope with their loss. It's especially important to consider becoming an organ donor if you belong to an ethnic minority.

The main parts of the system are the heart, arteries, capillaries and veins. The circulatory system does a very important job in your body. It carries oxygen and essential nutrients to all cells around the body in arteries and carries the waste products and carbon dioxide in veins.
