1 WCSU BIO 106 NVCC BIO 212 BLOOD VESSELS LAB and ASSIGNMENT Courtesy of: Dr. Susan Maskel Professor of Biology Western ConnecDcut State University Danbury, CT Source materials: UCONN site: h6p:// Elaine Marieb Lab workbooks and others, as indicated. 2 Pulmonary CirculaBon O 2 poor blood from heart to lungs; O 2 rich blood from lungs to heart lecture textbook, Fig Systemic CirculaBon O 2 rich blood from heart to body Dssues; O 2 poor blood from body Dssues to heart

2 Example: Systemic CirculaBon 3 heart aorbc arch ascending aorta descending aorta renal artery kidney renal inferior vena cava heart ExcepBon: HepaBc Portal CirculaBon Blood from digesdve system picks up nutrients, toxins. Liver monitors nutrients, toxins. Blood from digesdve organs goes to liver before returning to heart. 4 digesbve organs hepabc portal liver hepabc s inferior vena cava heart

3 Cat DissecBon 5 Use only side sinks for cats Sink in back of room: people only!!!! 1 cat per 2 students Use same bag & preservadve unless leaking 2 tags in pencil (not pen) your name, your lab partner s name; 1 tag on paw; 1 tag on outside of bag about 1/8 cup preservadve in bag when stored NO CAT PARTS IN SINK! (if cat parts are found in sink, extra credit will no longer be given on lab quizzes & exams) rinse cat trays when finished clean your stadon with desk wash when finished The cat you receive should look very much like this cat. 412

4 or Incision Diaphragm Cut open your cat as indicated in this diagram. 427 In order to find the blood vessels, you need to cut away fat and other connecdve Dssues. Blunt probes: most useful dissecdng tool; use for separadng 8 Forceps: use for grasping & pulling Dssue Scalpels: cut Dssues held by forceps

5 726 9 This is what an excellent dissecdon looks like EXCEPT: (1) do not cut off the body wall. Just move it to the side, and (2) see next. This picture did not come from your labbook greater omentum 10 Try not to cut out the greater omentum (an apron- like layer over the abdominal organs); just push it to the side

6 External jugular Brachiocephalic Larynx Trachea Vagus nerve 11 Superior vena cava (precava) Heart Lobe of lung Lobe of liver Small intestine 10 th & 11 th edioons: 726 Integrated edioon: 432 Aorta Diaphragm (cut) Stomach Kidney Spleen Large intestine Urinary bladder Arteries 12 R. & L. common carodd arteries

12 To find hepabc s 23 Find where inferior vena cava passes by liver Using scalpel, scrape away liver Dssue in that area HepaDc s will appear To find hepabc portal Remove peritoneum between first part of small intesdne (duodenum) and liver. HepaDc portal should appear brown Copyright protected 2000, Susan Caley Opsal.
