animal physiology (internal transport) challenge #4 Flashcards
1
Q
what is a circulatory system?
A
a specialized system in which materials can be “efficiently” transported through the body
2
Q
what are the Three Basic Components of all Circulatory Systems?
A
- Muscular Pump
- System of conduits
- Fluid that is circulated
3
Q
what is the simplest form of a muscular pump?
A
Pulsatile Blood Vessel
4
Q
how does the Pulsatile Blood Vessel work?
A
Blood vessel is lined with muscular tissue which allows the contraction of the tissue to push the circulatory fluid through the system
5
Q
how are the more complex hearts different than the simple muscular pump?
A
application of valves and expansion of musculature to move circulatory fluids
6
Q
what are the Two Basic Types of Circulatory Systems?
A
- Open System (fluid escapes vessels -dumps blood on organs)
- Closed System (fluid always contained)
7
Q
what are the two types of fluid in each circulatory system?
A
- hemolymph in open systems
2. blood in closed systems
8
Q
what are 3 functions of blood?
A
- transportation
- defense
- regulatory functions
