1 Interdependence in Living Systems

2 Any group of parts that work together as a unit.
Systems Any group of parts that work together as a unit.

3 How the body is organized:
Cells – First level of organization; the basic unit of structure and function. Tissues – a group of cells that perform the same function.

4 Types of Tissues Muscle Connective Nerve Epithelial

5 A group of tissues that perform a specific function.
Organs A group of tissues that perform a specific function.

6 A group of organs that work together to perform a specific function.
Organ Systems A group of organs that work together to perform a specific function.

7 Interactions Within the Human Body
Each organ system is dependent on other body systems.

8 Main components – BRAIN, SPINAL CORD, AND NERVES
Nervous System Obtains and processes information from the body’s internal and external environment; directs most body functions. Main components – BRAIN, SPINAL CORD, AND NERVES

9 Cardiovascular System
Transports needed materials to body cells; removes wastes (main components – HEART, ARTERIES, VEINS)

10 Digestive System Breaks down food and absorbs the broken-down materials (main components – LIVER, STOMACH, GALL BLADDER, SMALL INTESTINE, AND LARGE INTESTINE)

11 Respiratory System Gets oxygen into the body; removes carbon dioxide. (Main component – TRACHEA, LUNGS, AND DIAPHRAGM)

12 Enables the body to move
Muscular System Enables the body to move

13 Skeletal System Supports and protects the body; works with muscles to enable movement processes

14 Endocrine System Produces chemicals called hormones that help control many body processes (Main components – GLANDS, PANCREAS, AND KIDNEYS THAT PRODUCE HORMONES)

15 Excretory System Removes wastes; helps regulate water in the body (Main component – KIDNEY)

16 Immune System Fights Disease (Main components – LIVER, LYMPH NODES, WHITE BLOOD CELLS, BLOOD, AND THYMUS)

17 Skin (Integumentary) System
Protects the body, keeps water inside, and helps sense the external environment

18 Reproductive System Create offspring, determines male and female characteristics (Main Components – OVARIES and TESTES)

19 Interactions in TRANSPORTING OXYGEN
RESPIRATORY – delivery of oxygen and removal of carbon dioxide. Trachea – tube connecting to the lungs Alveoli –round sacs in the lungs Moves oxygen from air to blood Moves carbon dioxide from blood to air CARDIOVASCULAR – carries oxygen from lungs to bloodstream MUSCULAR – enables air to enter lungs Diaphragm – dome shaped muscle

20 Interactions in DIGESTING FOOD
DIGESTIVE – breaks down food into simpler substances to be used by body cells Mouth and Stomach – begins to break down food Small Intestine – Completes the breakdown of food and absorbs the nutrients (through villi) Large Intestine – undigested food passes out of the body as waste

21 Interactions in DIGESTING FOOD
MUSCULAR – moves jaws to break down food. Absorption of nutrients Enables you to swallow food Within the stomach – food is churned and squeezed, broken down into smaller particles

22 Interactions in DIGESTING FOOD
CARDIOVASCULAR – carries nutrients absorbed through the small intestine to the blood. Nutrients are carried throughout the body.

MUSCULAR – produce movement by contracting or shortening SKELETAL – muscles attached to bones move your body NERVOUS – involved in movement. Brain and nerves direct muscles to contract. CARDIOVASCULAR – circulates oxygen and food to cells RESPIRATORY – brings oxygen into body, removes carbon dioxide DIGESTIVE – processes food for delivery to cells
