Cardiovascular
Relating to the circulatory system, which is made up of the heart and blood vessels. Also, carries nutrients and oxygen to the tissues of the body and removes carbon dioxide and other wastes from them.
Written Procedure:
1. Locate the diaphragm and the heart. They are centrally located in the thoracic cavity. The thymus gland, may be visible at the upper part of the heart.
2. The lungs are spongy organs that lie on either side of the heart and should take up most of the thoracic cavity. They lie closer to the back of the rat, you will need to push the ribs to the side to find them.
3. A sheet of muscle can be found just under the heart (and above the liver) - this is the diaphragm. This muscle is only found in mammals. (The diaphragm may have been cut when you opened the thoracic cavity.)
4.Remove the heart from the pericardial sack.
5.Sever the arteries and veins connecting the heart to the circulatory system. Do this slowly and carefully so that you do not cut more than is necessary.
