Anticipatory Set


Organ Systems Homeostasis

Big Idea


California Standards

Science Standard 7.5.a:

Students know that plants and animals have levels of organization for structure and function, including cells, tissues, organs, organ systems, and the whole organisms.

  • Plants and animals have levels of organization for structure and function.


Input

  • Cells: the smallest units of organization in the body.

  • Connective Tissue: provides support for your body and connects all of its parts.

  • Muscle Tissue: allows your body to move (can contract and shorten)

  • Nervous Tissue: directs and controls movement( carries electrical messages back and forth between the brain and other parts)


Input

  • Epithelial tissue: the tissue that covers your body inside and out.

  • Homeostasis: the body’s tendency to keep an internal balance.

  • Pathogens: disease causing bacteria and viruses.

  • Stress: your body’s reaction to potentially threatening, challenging, or disturbing events.


Input How the body is organized

  • The levels of organization in the human body consist of cells, tissues, organs, and organ systems.

Cells

Tissues

Organs

Smallest unit

of organization

Organ Systems

Largest unit of organization


InputTissues

  • the second largest unit of organization in your body (4 basic types of tissue)

  • Muscle tissue- contract and shorten

  • Nervous tissue – carries electrical charges to brain and other parts

  • Connective tissue – provides support

  • Epithelial tissue – Cover your body inside and out. (e.g. the skin provides protection)(e.g. lining of the digestive system allows you to digest and absorb nutrients from food.


InputOrgans and Organ systems

  • The Integumentary System

  • Made up of you skin, hair, and nails.

    • Cells and tissue work together to provide a barrier from disease causing bacteria and viruses.

    • Skin also helps regulate body temperature.

    • Also helps the excretory system remove waste (sweating)

    • Works with the nervous system to give you info about your environment.

  • The human body has 11 organ systems


InputOrgans and Organ systems

  • All systems of the body work together to maintain homeostasis

  • HOMEOSTASIS IS THE PROCESS BY WHICH AN ORGANISM’S INTERNAL ENVIRONMENT IS KEPT STABLE IN SPITE OF CHANGES IN THE EXTERNAL ENVIRONMENT

  • The human body has 11 organ systems


Finish the Front of Notes on your own

  • Across Discipline: Language Arts (RC 2.2 (take notes on the 11 body systems. e.g what organs are involved, how does the system help maintain homeostasis.)

  • Patterns: Draw and label one of the 11 body systems.(511-515)

  • Question: Write a question and answer it.

  • Summary: Write a summary of what you have learned.


InputOrgans and Organ systems

  • The Skeletal System

  • Made up of your bones and connective tissues.

    • Supports the body and gives structure.

    • Protects your body’s organs

    • Connective Tissues attaches bones and form joints that allow movement

  • The Muscular System

  • work to move your body by pulling your skeleton

  • Voluntary Muscles – work when you want them to

  • Involuntary Muscles – work by themselves

  • Your muscles and bones are also know as the Musculoskeletal system.


InputOrgans and Organ systems

  • The Circulatory System

  • Carries food and oxygen to all the cells of your body.

  • Powered by the pumping of your heart.

  • Arteries – take blood away from the heart

  • Veins – carry blood toward the heart

  • Capillaries – smallest blood vessels connect arteries and veins.


InputOrgans and Organ systems

  • The Respiratory System

  • lungs are the main organs in the respiratory system

  • Takes in oxygen and disposes carbon dioxide

  • Delivers oxygen to the blood via circulatory system

  • The Digestive System

  • helps breakdown food into small molecules the body uses


InputOrgans and Organ systems

  • The Excretory System

  • Removes waste from you blood stream

  • Kidneys are the major organ in this system

  • Each kidney contains 1 million nephrons that filter waste.

  • The Immune System

  • Protects your body from disease-causing bacteria and viruses called PATHOGENS.

  • Specialized white blood cells target and destroy these PATHOGENS.


InputOrgans and Organ systems

  • The Nervous System

  • takes the information from your environment and from within our body.

  • Processes information and demands the body to respond

  • Includes the brain and spinal cord

  • Nerve cells reach form spinal cord to all parts of the body

  • The Endocrine System

  • helps regulate the activities of your organs and organ systems.( releasing hormones)

  • Consists of Thyroid gland, Hypothalamus, Parathyroid glands, Thymus gland, Pancreas, Adrenal glands.


Input HOMEOSTASIS

  • All systems of the body work together to maintain homeostasis

  • HOMEOSTASIS IS THE PROCESS BY WHICH AN ORGANISM’S INTERNAL ENVIRONMENT IS KEPT STABLE IN SPITE OF CHANGES IN THE EXTERNAL ENVIRONMENT
