Each piece is custom cut, making for unique puzzles to put together. Featuring accurate medical science and human anatomy, these puzzles help highlight the complexities of our bodies and what makes us up. When finished assembling these exquisite pieces, you will be in awe of your accomplishment and your body's complexity.Assemble the human heart at 600% magnification! You'll assemble an accurate cross-cut section of the heart that gives you a detailed interior view from the brachiocephalic artery to descending aorta. Focusing on the powerhouse of our cardiovascular system, this puzzle shows what it takes to pump 2,000 gallons of blood daily throughout our bodies. See the atria and ventricles that contract and relax to circulate oxygen and other nutrients. Follow the pulmonary vessels that transport carbon dioxide and other waste products to be replenished or discarded. Note the pericardium that protects and preserves our heart. 597 pieces. Assemble the human brain at 500% magnification! You'll assemble an accurate cross-cut section of the head that gives you a detailed interior view from corpus callosum to spinal cord. Focusing on the hub of our central nervous system, this puzzle uncovers the astounding organ that gives rise to our inner experience and takes in sensory data. See the cerebrum that enables us to reason, the cerebellum that allows us to explore the world, and the brain stem that tells our hearts to beat. Trace the brain's lobes and hemispheres; locate its deep structures and encasing bones. Track the woven nerves from which we perceive our surroundings, the blood vessels that keep us nourished, and the protective tissues that keep our brains intact. 662 pieces. Assemble the human hands at over 400% magnification! In this volume, you'll assemble an accurate cross-cut section of the hands that gives you a detailed interior view from the ulnar artery to the distal phalanx. Focusing on our prehensile appendages, this puzzle displays the numerous intricate systems that enable us to grasp our surroundings and connect with our kin. Count the bones that gird our great dexterity. Trace blood vessels as they weave throughout the wrist and onward. Track the median and other nerves that convey crucial tactile information. See the hinge joints at the fingers' knuckles that give us a powerful grip and the ligaments that limit our extension. Note the flexor tendons that allow us to straighten our digits and the abductor pollicis that helps move our opposable thumbs. 512 pieces. Assemble the human feet at over 400% magnification! In this volume, you'll assemble an accurate cross-cut section of the feet that gives you a detailed interior view from the tibia to the distal phalanx. Focusing on our body's foundation, this puzzle illustrates the rigid yet flexible structures upon which we stand, walk, run, climb, and jump. See the bones that combine to keep us upright and the articulated joints that provide us with an impressive range of motion and bipedal balance. See the talus' mortise and tenon joint with the tibia that enables us to bend and flex. Note the thick Achilles tendon that springs us into action and the flexor retinaculum and other ligaments that bind everything together. Follow blood vessels like the tarsal artery that supply these weight-bearing wonders. 764 pieces. Assemble the human eye at over 2000% magnification! In this volume, you'll assemble an accurate cross-cut section of the eye that gives you a detailed interior view from the lateral rectus muscle to the cornea. Focusing on our windows to the world, this puzzle illuminates the many specialized parts that empower us to see. Look through the lens that, along with the cornea, allows light into the eye and focuses its rays onto the retina, a nerve layer that contains photosensitive cells. Observe the iris and pupil that act like a camera's diaphragm and aperture to adjust to our surroundings and control the amount of light we take in. Marvel at the macula that gives detailed clarity to our sight. Find the optical nerve, the sum of more than a million fibers that transmit impulses from the retina to the visual cortex. Track the extraocular muscles that rotate our eyes and expand our field of vision. 544 pieces.
