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)

Cells Tissues Organ System Organism

The eleven organ systems of the human body work together to maintain homeostasis in the body a 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
