Questions:

1. A group of cells that work together to perform some function in the body is called a(n) _____________________________.
2. A group of tissues that work together to perform some function in the body is called a(n) ___________________________.
3. A group of organs that work together to perform some function in the body is called a(n) ___________________________.
4. Tissue made of long cells with the ability to shorten (contract) is called _____________________________ tissue.
5. Skin and linings of organs are made up of ____________________________ tissue.  What aspect(s) of the structure of this tissue make it good for lining things?
6.  Bone and cartilage are examples of ___________________________ tissue.  This tissue differs from other tissues in that:
    a. cells are right next to each other so that the tissue forms solid sheets
    b. cells can conduct electricity
    c. the function of the tissue depends largely on materials surrounding the cells, produced by the cells
    d. cells can shorten (contract) to pull parts of the body closer together
7.  Tissues made of long cells that function by transmitting electric impulses to other cells is called _____________________ tissue and occurs in the ________________________ system.
8.  True or False: Blood is considered a tissue even though cells are not touching each other because the cells work together to perform the functions of blood
9.  The body gets rid of three main kinds of waste product.  The waste product of cellular respiration is carbon dioxide; the system that rids the body of carbon dioxide is the ___________________________ system.  The waste products of broken down food that are never taken into the blood leave the body through the ___________________________ system.  The waste products of biochemical reactions in cells such as the breakdown of proteins are lost from the body through the ___________________ system.
10.  There are two main systems regulating body conditions.  The system that is involved in rapid response and complex processing of information and functions based on transmission of electrical electric impulses is the ______________________ system.  The system that is involved in slower response and maintenance of conditions and is based on chemicals circulating in the blood is the __________________ system.
11.  The circulatory system interacts with several other physiological systems.  Explain how it interacts with each of the following: the immune system, the digestive system, the respiratory system, the excretory system, the endocrine system.
