 Integumentary System
     1. Anatomy: Use the words in the box to fill in the blanks.

Dermis          Epidermis      Hair Follicle            Hypodermis            Keratinocyte           Three


     The skin has ____________ major layers. The top most layer is called the ________________________.
     This layer is made of dead skin cells called ______________________________. Beneath the epidermis is
     the ________________________. This is the thickest layer, containing sweat glands, oil glands, blood
     vessels, muscle fibers, nerve endings, and __________________________________________. The bottom
     most layer is called the ___________________________ or subcutaneous fat layer.
     Use the words in the box to label the diagram below.

     2. Physiology:
                1. _________________________________ – skin maintains body temperature through sweating,
                   shivering, and goosebumps.
                2. _________________________________ - the skin keeps foreign invaders from entering the
                   body and protects you from UV radiation
                3. _________________________________ - nerve endings in the skin allow for feeling
                4. _________________________________ - sweating helps get rid of excess salts and wastes
                5. _________________________________ - in the sun, the skin makes Vitamin D


  Skeletal System
         1. Anatomy: Use the words in the box to fill in the blanks.

       Cartilage                Compact Bone           Joint            Ligaments              Marrow
                       Periosteum                Spongy Bone                        206


         The adult human body has about ____________ bones. The outermost layer of the bone is called the
         __________________________________. This thin, protective layer is where strong elastic bands
         called tendons and __________________________ connect to the bone. Beneath the periosteum is a
         hard white layer called _______________________. Directly beneath this layer is the
         _____________________________, which makes bones lightweight. In the middle of bones is
         __________________________, which makes red and white blood cells. On the ends of bones is
         __________________________, a slippery substance that allows bones to move without rubbing
         together. This place where two or more bones meet is called a ____________________.
  Use the words in the box to label the picture below.

 Cartilage                 Compact Bone                  Marrow                Periosteum             Spongy Bone




      2. Physiology
           1. ___________________________ - the skeleton provides us with shape and support and many bones
               protect internal organs
           2. ___________________________ - bones work with muscle to provide movement
           3. ___________________________ - marrow inside bones makes blood cells
           4. ___________________________ - long bones store fat and minerals


  Muscular System

          Tendon                         Voluntary                       650


           1. Anatomy: Use the words in the box to fill in the blanks.
               Muscles and tendons are the two main organs in the muscular system. You have over ___________
               muscles in your body. Muscles can be divided into two main categories based on conscious control.
               _________________________________ muscles work automatically and subconsciously. The
               muscle of the heart, called ______________________ muscle is involuntary and never tires. Another
               type of involuntary muscle is ____________________ muscle, which makes up internal organs like
               the diaphragm and digestive tract. Muscles that are under your conscious control are called
               ____________________________ muscles and are made up of ______________________ muscle
               fibers. These muscles are connected to bones by strong elastic bands called
               ________________________. Skeletal muscle get tired and cramps when it does not have enough
               ____________________ and glucose.
           2. Physiology
                   1. _______________________ - muscles work and organs to cause movement
