Circulatory System Flashcards
3 functions of circulating blood:
- transportation
- regulation
- protection
Composed of 92% water. Contains nutrients, wastes, hormones, ions (NA,CL, HCL3), and protein (fibrinogen)
Blood plasma
Mature mammalian erythrocytes lack ____.
Nuclei
______ are larger than erythrocytes and have nuclei. Can migrate out of capillaries into tissue fluid. Granular and agranular types.
Leukocytes
_____ are cell fragments that pinch off from larger cells in the bones marrow. Function in the formation of blood clots.
Platelets
_____ develops from pluripotent stem cells.
Platelets
Sponges, cnidarians, and nematodes lack a separate _____
Circulatory system
_____ circulatory system has no distinction between circulating and extracellular fluid. Fluid called hemolymph.
Open
_____ circulatory system, distinct circulatory fluid enclosed in blood vessels and transported from and to the heart.
Closed
____ have evolved a true chamber pump heart. Have a 2 chambered heart. Blood pumped through gills to the rest of the body.
Fish
_____ advent of lungs require a second pumping circuit, or double circulation. Pulmonary circulation moves blood between the heart and lungs. Systemic circulation moves blood between the heart and the rest of the body.
Amphibians
The _____ heart is 3 chambered
Amphibians
_____ have a 4 chambered heart. 2 atria 2 ventricles.
Mammals, birds, crocs
_____ atrium receives deoxygenated blood from the body and delivers it to the right ventricle, which pumps It to the lungs.
Right
_____ atrium receives oxygenated blood from the lungs and delivers it to the left ventricle which pumps it to the rest of the body.
