Vascular System 2; Lymphatic System

Vascular System II; Lymphatic System: Professor Diamond continues the second lecture on the vascular system beginning with a closer look at the middle cerebral artery, its composition and function, as well as its relationship with other areas of the brain. The second set of the more distinctive arteries are the vertebral arteries, which supply about 25% of the brain’s blood supply. After covering how the vascular system relates to the spinal cord, Professor Diamond moves onto the lymphatic system, dissecting its constituents which include: lymphatic tissue (spleen, lymph nodes, thymus, and tonsils), lymphatic vessels, and lymph. She discusses each of the lymphatic tissues in detail, including its location, composition and function. The lecture concludes with photos of each of the lymphatic tissues.
