Mr. Vais 3/27/11

What is a System? How do they work? How have they evolved? What are some of the Systems in our body?

Systems we will cover Circulatory Digestive Endocrine Immune Muscular/Skeletal Nervous Reproductive Respiratory Urinary

Circulatory System Function - pumping and channeling blood to and from the body and lungs with heart, blood, and blood vessels. Components - Heart, Veins, Blood Vessels Key Words - Pulmonary Circulation - Systemic Circulation

Picture of Circulatory System

Digestive System Function -digestion and processing food. with salivary glands, esophagus, stomach, liver, gallbladder, pancreas, intestines, rectum, and anus. Components/Key Words - salivary glands, esophagus, stomach, liver, gallbladder, pancreas, intestines, rectum, and anus. Key Learning Target -How does our body use this system to create energy?

Picture of Digestive System

Endocrine System Function - communication within the body using hormones made by endocrine glands. Components - Glands (pituitary, adrenal) - thyroid and parathyroid Key Learning Target - How does our body communicate, and what signals are used for the communication?

Pictures of Endocrine System

Immune System Function - This system aids our body in fighting off disease Components - leukocytes, tonsils, adenoids, thymus, and spleen Key Learning Target -

Muscular/ Skeletal System Function - Muscular system aids the body in movement, while Skeletal system provides support and protection Components - Names/ Types of muscles, contraction/ extension - Names of Bones, Types of Joints *Will be a difficult section if you are unable to recognize location and name of muscles or bones

Pictures of Muscular System *not required to know entire diagram, required will be given in class

Picture of Skeletal System

Nervous System Function - collecting, transferring and processing information with brain, spinal cord, peripheral nerves, and nerves Components - How are signals sent an received? - Central Nervous System - Peripheral Nervous System - What is the role of a Neuron

Picture of the Nervous System

Reproductive System Function - Sex organs used for reproduction in the male and female Components - Male reproduction organs - Female Reproduction organs - Cycles of each, reproductive maturity, process of fertilization

Respiratory System Function - Organs used for breathing to supply the blood with oxygen Components - Process of breathing - How does our body process the oxygen we breathe? - What happens when you become short of breathe?

Picture of Respiratory System

Urinary System Function - Liquid balance within the body, excretes urine which is liquid waste to the body Components - Know organs involved (Kidneys, Bladder, Urethra) - How does liquid pass through the body, both as useful liquid and waste? - Know the importance of liquid to run all our other body systems

1. Human urinary system: 2. Kidney, 3. Renal pelvis, 4. Ureter, 5. Urinary bladder, 6. Urethra. (Left side with frontal section) 7. Adrenal gland Vessels: 8. Renal artery and vein, 9. Inferior vena cava, 10. Abdominal aorta, 11. Common iliac artery and vein With transparency: 12. Liver, 13. Large intestine, 14.

Other Important Information for Unit Recognition that for each of these systems there is disease and complications that can arise - To successfully understand this unit you must not only know functions of these systems, but recognize the problems that can arise within each of them Included in this unit will be recognizing the evolutionary trends that took place between higher order organisms

Websites for Systems Disease’s Circulatory ( Digestive ( Endocrine ( Immune ( Muscular/Skeletal ( Nervous ( Reproductive ( Respiratory ( Urinary (

Study Advice for Unit Vocabulary Words - Each system will come with its own set of Vocabulary words. KNOW THEM!!!!!! Each word will help understand how the individual parts function as a system. Diagrams - Very useful for understanding the path from start to finish of each system. Also, aids with recognition of parts and their locations.
