Cells – A cell is the ____________________________ Specialized cells are uniquely suited to perform a particular function.

Cells – A cell is the basic unit of structure and function in living organisms Specialized cells are uniquely suited to perform a particular function.

______________________ – A group of cells that perform a single function is called a tissue. There are 4 basic types of tissue: 1.____________________ – glands and tissues that cover interior and exterior body surfaces (ex: skin) 2.____________________ – provides support for the body and connects its parts (ex: bone, cartilage) 3.____________________ – transmits nerve impulses (ex: nerve cells, brain cells) 4.____________________ – enables the body to move (ex: heart, bicep)

The eleven organ systems of the human body work together to maintain homeostasis in the body as a whole. Homeostasis is the ability to keep an internal balance despite changes in external conditions. Examples: When your body temperature gets too high, you sweat. When your body temperature gets too low, you shiver. When your diaphragm (your breathing muscle) gets irritated, you hiccup.

The_hypothalmus is the area of the brain that controls homeostasis. In order to maintain homeostasis, your body relies on a feed back system_. Negative Feedback – The body produces a response that is the opposite of the stimulus. This keeps the body in balance. Ex – cold temperatures produce a shivering effect to keep warm Positive Feed back – the body overproduces a response to a stimulus in order to prevent shock or damage. Ex – The body produces an unusual amount of adrenaline when scared in order to enhance “ fight or flight ” mode

The 4 ways we will study body systems is to categorize them into the following functions: 1.Regulation: Excretory & Nervous Systems 2.Nutrient absorption: Respiration, digestion and circulatory systems 3.Defense: Immune, Integumentary, Lymphatic, Skeletal, & Muscular systems 4.Reproduction: Reproductive & Endocrine systems

Muscular System Provides movement

Skeletal System Supports the body and protects organs

Circulatory System Transports nutrients and gases

Nervous System Transmits messages through the body

Lymphatic (Immune) System Protects the body against infection

Respiratory System Facilitates gas exchange with the environment

Endocrine System Produces hormones and is responsible for growth and development Thyroid gland

Digestive System Breaks down food into chemical energy that the body can use

Excretory System Removes toxins from the body

Reproductive System Produces offspring

Integumentary system Skin – protects the body  Write this on your notes. There is no picture
