BIO270 Laboratory Guide #9
CIRCULATORY AND LYMPHATIC SYSTEMS;
BLOOD
After completing this laboratory you should be able to:
1) Describe the structure of the heart for each of the vertebrate classes;
2) For each vertebrate heart, identify the chambers and major structures detailed in the list below, and be able to relate those to the flow of blood through the heart and the overall circulatory system;
3) Identify each of the specific blood vessels of the shark, mudpuppy, and cat in the list below;
4) Be able to distinguish hitological smears of blood from the various vertebrate groups;
5) Identify each of the specific lymphatic organs of the shark, mudpuppy, and cat in the list below.
I. HEART AND CIRCULATORY SYSTEM
1) Work through Z&K exercise #8, involving the circulatory systems of the shark, mudpuppy and cat.
2) Be able to distinguish the hearts of representative vertebrates and identify the chambers and other major structures in the shark, amphibian, and mammalian heart, as specified in the list below.
3) Be able to identify the blood vessels on the accompanying list. For each be able to state:
what organs/regions it supplies/drains
what vessel it branches off of/flows into
what the major branches/tributaries are.
4) Pay special attention to the form and function of the hepatic portal system.
