Study Notes
Circulatory Systems in Animals
-
Double Circulation (Mammals and Birds): Blood circulates through the heart twice in one cycle.
- Pulmonary circulation: blood travels to the lungs and back.
- Systemic circulation: blood flows to the body and back.
- Benefit: lower pressure to the lungs to prevent damage, higher pressure to the body for efficient delivery to extremities. Increased circulation speed.
-
Single Circulation (Fish): Blood passes through the heart only once per cycle.
- Simple heart: one atrium and one ventricle.
- Limitation: lower pressure and slower circulation, which limits organism size. Blood cannot reach high pressure without damaging the gills.
-
Open Circulation (Insects): Blood (hemolymph) isn't contained within vessels.
- Fluid circulates around the body, often driven by the animal's movement.
- Cells bathe directly in the hemolymph for nutrient exchange.
- Less efficient than closed systems, limiting organism size.
-
Closed Circulation (General): Blood is contained within blood vessels (arteries, veins, capillaries).
- Tissue fluid surrounds cells, delivering nutrients and removing waste.
- More efficient than open systems, allowing for larger organism size and faster nutrient and gas exchange.
