    Study Notes

    Skeletal System Function

    • Provides shape and support to the human body.

    Protection of Major Organs

    • The skeletal system protects most major organs.

    Muscular and Respiratory Systems

    • The respiratory system provides oxygen for the muscular system's use.

    Heart Location

    • The heart is part of the circulatory system.

    Digestive System Parts

    • The digestive system includes the mouth and teeth.

    Circulatory System Function

    • Transports blood.

    Body Movement System

    • The muscular system helps the body move.

    Nervous System Function

    • Sends messages to the brain.

    Lungs in the Body

    • The respiratory system includes the lungs.

    Digestive System Organ

    • The stomach is part of the digestive system.

    Respiratory System Function

    • Takes in oxygen and removes carbon dioxide.

    Digestive System Function

    • Breaks down food for nutrient absorption.

    Body System Interdependence

    • Body systems work together to avoid complications.

    Body Systems Working Together

    • The skeletal and muscular systems work together to support the body and enable movement.

    Nervous and Muscular Systems Relationship

    • The nervous system controls the muscular system.

    Excretory System and Digestive System Function

    • Both systems eliminate wastes.

    Muscle Types

    • Skeletal, smooth, and cardiac muscles.

    Gravity and Food Movement

    • The esophagus (not gravity) moves food through the body to the stomach.

    Reproductive System

    • Females produce eggs/nourish fetuses; males produce/deliver sperm.

    Oxygen and Red Blood Cells

    • Red blood cells carry oxygen to muscle tissues.

    Organ System Interconnection

    • Many organs are components of more than one body system.

    Organ System Order

    • Organism -> Organ System -> Organ -> Tissue -> Cell

    Blood Gases

    • The blood transports and removes oxygen and carbon dioxide.

    Heart Valves

    • Heart valves prevent blood backflow.

    Nervous System and Digestion

    • The nervous system directs signals to the stomach and intestines for digestion.

    Digestion Process

    • Digestion begins in the mouth, involving enzymes and acids to break down food.

    Nutrient Absorption

    • Nutrients are absorbed by the small intestine.

    Metabolic Waste

    • Metabolic waste includes urea and carbon dioxide.

    Epidermis and Excretory System

    • The epidermis is not part of the excretory system.

    Stomach Lining Muscle

    • Smooth muscle cells line the stomach.

    Central Nervous System

    • Nerves in the entire body are part of the central nervous system.

    Gas Exchange in Respiration

    • Gas exchange (oxygen and carbon dioxide) occurs in the alveoli.

    Skeletal System Composition

    • The skeleton consists of bones.

    Interconnected Organ Systems

    • Multiple organ systems work together in actions like running.
