Human Circulatory System Models
Active Demonstration Of Heart Function And Blood Circulation
- Easy To Assemble And Clean
- Visualize Circulation Through Lungs And Heart
Show students the circulatory system in action with this working model. Simply squeeze the simple bulb “pump” to send the dyed liquid through the four-chambered heart and plastic “vessels”. The venous tubing is tinted blue to differentiate between oxygenated and nonoxygenated blood. Dye and a syringe are included to refill the system. The one-piece model is mounted on a base and includes a teacher’s guide. Size: 14 1/4"L x 6 1/4"W x 15"H.
