Week 6: Nervous System and Unit 6 Part 2 Review Unit 6: Human Body Week 6: Nervous System and Unit 6 Part 2 Review

SC Standards Standard 7.L.3: The student will demonstrate an understanding of how the levels of organization within organisms support the essential functions of life. 7.L.3B Conceptual Understanding: Multicellular organisms (including humans) are complex systems with specialized cells that perform specific functions. Organs and organ systems are composed of cells that function to serve the needs of cells which in turn serve the needs of the organism. 7.L.3B.2: Construct explanations for how systems in the human body (including circulatory, respiratory, digestive, excretory, nervous, and musculoskeletal systems) work together to support the essential life functions of the body. S.1A.6: Construct explanations of phenomena using (1) primary or secondary scientific evidence and models, (2) conclusions from scientific investigations, (3) predictions based on observations and measurements, or (4) data communicated in graphs, tables, or diagrams

SC Objectives It is essential that students construct explanations for how systems in the human body (including circulatory, respiratory, digestive, excretory, nervous, and musculoskeletal systems) work together to support the essential life functions of the body. It is essential for the student to be able to understand the basic form and function of each of the following body systems as well as the interrelationships that occur between systems to ensure the survival of the organism.

Bell Work What are the primary organs of the digestive system? Describe the function of 3 of the primary organs. Name and describe 2 organs of the excretory system.

Nervous System The main functions of the nervous system: to receive stimuli from inside and outside the body to interpret the stimuli initiate responses for survival.

Brain An organ which has three distinct that all serve to control and coordinate the activities of the body.

Parts of the Brain The cerebrum is the largest part of the brain. Controls thoughts, Voluntary actions The sensations related to the five senses. The cerebellum is the small lobe located at the back of the brain. Helps with balance and coordination. The brain stem is located at the base of the brain Controls vital and involuntary processes Example, breathing, the beating of the heart, and digestion

Parts of the Brain

Spinal Cord A bundle of nerves Begins at the brainstem Continues down the center of the back through the vertebrae. It connects with the peripheral nerves.

Peripheral Nerves A network of nerves that branch out from the spinal cord Connect to the rest of the body Transmit signals to and from the brain through the spinal cord

Nerves

Relationships of the Major Body systems Each system in the human body performs specific function Different systems work together and depend on one another

Circulatory All systems depend on the circulatory system to transport materials Circulatory system works with the excretory system to remove wastes Respiratory system works with the circulatory system to make sure that oxygen (O2) reaches the bloodstream carbon dioxide (CO2) is removed from the bloodstream The digestive system works with the circulatory system to make sure that nutrients made available by digestion get to the cells of the body

Nervous Control is ALL The nervous system works with the muscular and skeletal systems to direct behavior and movement. The nervous system controls internal processes in the body Example digestion and circulation

Muscles Muscles control the movement of materials through some organs Example the stomach, intestines, and the heart
