Human Body Systems: Muscles and Skin

The video tutorial, presented by Carly, Jared, Peyton, and Trevor, covers the muscular and integumentary systems. It begins with an introduction to the integumentary system, highlighting its role as the largest organ in the human body with three layers: epidermis, dermis, and subcutaneous. The integumentary system's functions, including protection, immune support, and homeostasis, are discussed. The tutorial then transitions to the muscular system, explaining the three types of muscle cells: cardiac, smooth, and skeletal. The relationships between muscles, bones, and connective tissues in the musculoskeletal system are also covered.
