As students walk in, give each student a clip art of an organ. Students will need to find the chart paper that has the body system his/her organ belongs to. Students will need to wait at the chart paper until all students have completed the task. Students will then discuss with their group members why they placed the organ on that chart paper. This activity can be used as a pre-assessment, a too to access prior knowledge, and a strategy to create expert groups.

Homeostasis-the monitoring and adjusting that goes on in the human body at any given time-is astounding. Your body continually makes adjustments to the body systems you use during everyday activities. In this interactive, make adjustments in respiration or heart rate or energy delivery in response to changing activities, and anticipate how a change in one system changes the balance in another system.

New discoveries about how the body's systems function and work together continue to emerge almost daily. However, a very basic and fundamental understanding of the body's integrated working parts and organ systems has been in place for centuries.

The cardiovascular system with its heart-pump and network of arteries and veins shuttles oxygen-rich blood from the lungs to all of the body's organs and tissues. Cells throughout the body take their fill of oxygen and nutrients and dispose of carbon dioxide and waste products, which eventually flow back to the heart's right-sided chambers; then on to the lungs to exchange carbon dioxide with oxygen. Inhaled air passes through your nasal passages, throat and lung airways reaching tiny alveoli, the site of gas exchange. The newly oxygen-rich blood travels back from the lungs to the heart's left-sided chambers, where it gets pumped out at great pressure via arteries to reach the needy tissues once again. And so the cycle continues. Other organ systems, such as the endocrine and nervous system, directly and indirectly regulate the cardiovascular system.

The digestive system is responsible for breaking down food into molecules small enough to be used by the body's cells and tissues. The food is broken apart through chewing and stomach churning, but also chemically -- through the stomach's acid-loving enzymes, and on to the small intestine, which receives pancreatic enzymes and juices specially tailored to dissolve and digest proteins, carbohydrates and fibers. Bile from the liver also works on fats. Though absorption of some drugs and alcohol may start in the stomach, absorption is mainly the function of the small intestines. Digestible nutrients pass through from the small intestines and their microvilli to capillaries and on to the liver for detoxification and further processing and conditioning, then out to the body.

Fibers, undigestible material, bile and loads of bacteria travel through the large intestines and out through the colon and rectum. The kidneys filter out wastes from the blood to form urine, which flows down the ureters and enters the urinary bladder. The bladder collects the urine and releases when full, out through a the urethra.

Both digestive and excretory systems are regulated with input from the nervous system and endocrine system, and the cardiovascular system is inextricably linked with bowel and kidney function on multiple levels.

The endocrine system system uses hormones, or chemical messengers across distances to effect target organs and tissues. Hormones are typically produced by a gland such as the pituitary, thyroid or gonads, and released into the bloodstream. The pituitary is is considered a master gland, since it governs the release of hormones by other glands. Unlike the nervous system, there is no physical "wiring" with neurons, however, and the hormones reach their target via the blood stream, where they exert their effect. The endocrine and nervous system may work together on the same organ, and each may influence the actions of the other system. The endocrine system largely governs many processes related to reproduction and sexual maturity, as well.

The immune system is a network of cells, tissues and organs that work together to attack pathogens that try to invade your body. Bacteria, parasites and fungi that may cause infection meet a system of immune soldiers, including T-lymphocytes, macrophages and neutrophils. With time, the immune system's B-lymphocytes can produce antibodies against a new unknown invader. The immune system also plays a role in detecting non-self markers on cells that may arise in cancer cells and due to organ transplants.

Stress, as perceived by the nervous system, can have a remarkable impact on the immune system and also the digestive system, which happens to be another major site of immune cell activity.

The integumentary system, or skin, is the body's first line of defense. It regulates body temperature, protects underlying layers of tissue from sun damage and prevents pathogens from freely entering your body. The integumentary system is also home to millions of nerves that respond to touch, pressure and pain. There are two interconnected nervous systems: the central nervous system and the peripheral nervous system. The central nervous system includes the spinal cord and the brain, which gets the information from the body and sends out instructions. The peripheral nervous system includes all of the nerves and sends messages from the brain to the rest of the body. The nervous system controls both voluntary and involuntary, automatic activities and bodily functions.

Both the nervous system and endocrine system serve to integrate the body's various other systems, keeping things in synch. When the cardiovascular system is low on fluid, such as in severe dehydration, the skin loses its normal resiliency and can actually form a "tent" when pinched, instead of springing back into shape.

The system that provides your body's shape is the skeletal system, and it is made up of cartilage and bone. There are 206 bones in the human skeleton that provide a hard framework able to support the body and protect the organs that they surround. Cartilage provides support with flexibility and resistance, and acts as padding to soften the pressure that is exerted from the bones. Movement in the body is the result of muscle contraction; when muscles combine with the action of joints and bones, obvious movements are performed, such as jumping and walking. The contraction of muscles provides the body posture, joint stability and heat production.

Google Classroom
-Video links and articles for each body system
-Students will select the links based on the expert group they have been assigned to.
-Students will work in their expert groups to complete a Tree Map to identify the organs of the system and provide details and the function of each organ.
*** Modified Tree Maps to meet student needs.
-Students will be regrouped so each member is from a different body system. Each member of the heterogenous group will share using his/her Tree Map.
