VBSC 421 Lab Quiz 6 (labs 19,20,21)
What are 2 functions of lymph nodes? - ANS-•immune surveillance
•lymphocyte production
What are 3 functions of the spleen? - ANS-•lymphocyte production
•reservoir of platelets (production of blood cells)
•red blood cell destruction
•immune surveillance
*What is a lacteal? - ANS-lymphatic capillary in a villi--> fluids absorbed leave and move
up to the subclavians
What is a thoracic duct? - ANS-collects fluid from intestines and rest of the body and
goes to the subclavian veins
What is the MALT in the small intestine? - ANS-peyer's patch
What is the MALT in the lung? - ANS-lymphoid nodules (in bronchi of lung)
What makes up the white pulp of the spleen and what does it produce? - ANS-lymphoid
follicles--> produce lymphocytes
What makes up the red pulp of the spleen? - ANS-splenic sinusoids
Lymph node vs lymph nodule - ANS-•*lymph node*: can be easily seen
•lymph nodule*: aggregate of lymphoid tissues (MALT)
Can you expect the branching pattern of every cat to be identical? - ANS-no, the
branching pattern is determined by the oxygen demands of the organs
What blood vessels feed blood into the circle of Willis? - ANS-1. Basilar
2. Internal carotid
What organ is supplied with blood from the Circle of Willis? - ANS-brain
Hepatic portal vein vs hepatic veins - ANS-•*hepatic portal vein*: drains blood from
intestine to liver
•*hepatic vein*: drains blood from liver
