Small structures inside of a cell that perform essential functions

18
Q

What is a level of body organization

A

Within multicellular organisms there’s division of labor. Space each part of the body has a job to do and as each part doesn’t special job, it works in harmony with all of the other parts

19
Q

What are the levels of body organization from simplest a complex

A

Cells, tissues, organs, systems, organisms (or cotso!)

20
Q

What are cells

A

The basic unit in the human body, all cells are specialized functions, examples are nerve cells, bone cells, and blood cells

21
Q

What are tissues

A

A group of specialized cells that work together to perform the same function

22
Q

What are the four basic types of tissue in the human body

A

Nerve tissue: carry signals back-and-forth from brain to body, muscle tissue: contracts and extends making body parts move, epithelial tissue: cover surface of body and organs, connective tissue : connects
parts of the body and provide support

23
Q

What are organs

A

A group of different tissues that work together to perform a specific function, it’s task is more complex than tissues, examples are heart is made of muscle and connective tissue used to pump blood throughout the body

24
Q

What is the organ system

A

Two or more organs that work together to perform a specific function, each organ system has its own function but the systems work together depends on what another, there are 11 different organ systems in the human body

25
Q
