Study Notes

Skeletal System Function

Provides shape and support to the human body.

Skeletal System Protection

Protects major organs.

Muscular System Dependence on Respiratory System

The respiratory system supplies oxygen needed by the muscular system.

Heart Location

The heart is part of the circulatory system.

Digestive System Parts

Mouth and teeth are parts of the digestive system.

Circulatory System Function

Transports blood.

Body Movement System

The muscular system helps the body move.

Brain Communication System

The nervous system sends messages to the brain.

Respiratory System Components

The respiratory system includes the lungs.

Digestive System Organ

The stomach belongs to the digestive system.

Respiratory System Function

Takes in oxygen and removes carbon dioxide; removes waste from the body.

Digestive System Function

Breaks down food so nutrients can be absorbed by the body.

Nervous and Muscular System Relationship

The nervous system controls the muscular system.

Systems for Body Support & Movement

The skeletal and muscular systems work together to support and move the body.

Waste Removal System

The excretory system filters and removes liquid waste from the body.

Shared Functions of Systems

Both the excretory and digestive systems eliminate wastes.

Muscle Types

Skeletal, smooth, and cardiac are the three muscle types.

Food Movement Through the Body

The esophagus squeezes food to the stomach.

Reproductive System Function

Females produce eggs and nourish the fetus; males produce and deliver sperm.

Oxygen Transport Cells

Red blood cells carry oxygen to muscle tissue.

Body Systems Interdependence

Body systems work together to avoid complications.

Body System Organization Order

Organism -> Organ System -> Organ -> Tissue -> Cell; Cell -> Tissue -> Organ -> Organ System -> Organism.

Blood Gases

The blood transports oxygen and removes carbon dioxide.

Heart Valve Function

Heart valves prevent blood backflow.

Digestive Processes

Digestion starts in the mouth and continues with enzymes and acids in the stomach.

Nutrient Absorption

Nutrients are absorbed in the small intestine.

Metabolic Wastes

Metabolic wastes include urea and carbon dioxide.

Epidermis and Excretory System

The epidermis (skin) is not part of the excretory system.

Stomach Muscle Type

Smooth muscle lines the stomach.

Central Nervous System

Nerves throughout the body are part of the central nervous system.

Respiratory Gas Exchange Location

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

Skeletal System Composition

The human skeletal system consists of 206 bones.

Interacting Organ Systems in Exercise

Multiple organ systems work together during exercise (running).
