Jigsaw: Concept Maps of the Systems of the Body PROCEDURE:

You will be working in a jigsaw group of 5 members. Each member is an “expert” in one of the systems described below. (Obviously, there are more systems of the body than the 5). Your task is to create a mind map/web that answers all the questions listed below in a meaningful and logical way. Consult the rubric that is provided when constructing your mind maps. After completion, your maps will then be evaluated by 3 groups: 1) your fellow “experts”; 2) your jigsaw group; and 3) your teacher.

1. The Digestive System List organs of the system and describe their functions, e.g. describe the

travels of a piece of food as it travels through the system. (with diagram) Compare mechanical digestion and chemical digestion. Describe the importance of the gall bladder, the liver and the pancreas in

digestion. Vocab to use: salivary glands, esophagus, stomach, small intestine, rectum,

gastric juices, hydrochloric acid, mucous, bile, chyme, bolus, peristalsis Other interesting facts on this system of the body

2. Respiratory System Identify the organs and functions involved in the system (with diagram) Explain the role of the ribs and diaphragm in the breathing process. Explain how breathing rate is controlled. Describe what happens between the alveoli and the capillaries. Vocab to use: alveoli, gas exchange, trachea, bronchi, bronchiole, lung,

respiration, inhalation, exhalation, diaphragm, diffusion. Other interesting facts on this system of the body

3. Circulatory System List the functions of the circulatory system. Trace the path of blood Label parts of the heart (with diagram) Compare blood on the right side and the left side of the heart. Describe the components of blood (rbc, wbc, platelets, plasma) How is blood produced in the body? Vocab to use: aorta, artery, capillary, vein, vena cava, atrium, valve, ventricle,

deoxygenated blood, oxygenated blood Other interesting facts on this system of the body

4. Excretory System Define excretion.

Describe the function of the skin, kidneys, liver, ureters, bladder, and urethra in the excretory process – i.e. what happens to waste (like protein) as it travels through the system and is excreted.

Describe the structure and function of the kidney and its parts (with diagram) Explain how the nephron functions. Vocab to use: kidney, nephron, filtration, ureter, urethra, urine, bladder,

renal artery, renal vein, wastes, sweat glands. Other interesting facts on this system of the body

5. Nervous System Describe the basic structure and function of the system. Describe the structure of a neuron and explain how it operates (diagram). List the parts and discuss the function of the Central Nervous System (CNS).

Discuss the structure and control centres of the brain. Explain how a nerve impulse travels (diagram) Explain what occurs during the reflex arc. Vocab to use: central nervous sytem (CNS), neuron, dendrite, cell body, axon,

sensory nerve, motor nerve, stimulus, reflex, brain, spinal cord. Other interesting facts on this system of the body
