Assemble an accurate cross-cut section of the right upper arm and forearm that gives you a detailed interior view from clavicle to finger’s fibrous sheath pumps blood through the pulmonary circulatory loop of the lungs. From there, once the blood is rich with fresh oxygen, it begins its journey through the systemic circulatory system to carry that oxygen to the rest of the body. Focusing on musculature, this puzzle shows how each muscle and tendon relates to the next. Together, this soft tissue enables us to flex and extend our upper limbs, push and pull, and precisely guide what we grasp.
