Skeletal System The human skeleton is divided into two main parts the axial skeleton and the appendicular skeleton. The axial skeleton consists of the vertebral column, the rib cage, and the skull. The appendicular skeleton consists of the pectoral girdles, the upper limbs, the pelvic girdle, and the lower limbs. Identify 20 major bones in the body. The following are major bones in the body: Cranium, mandible, femur, patella, scapula, ulna, clavicle, humorous, sternum, lumbar, vertebrae, cervical vertebrae, radius, pubis, carpals, metacarpals, sacrum, coccyx, tibia, phalanges, ilium, fibula, tarsals, and ribs. State the functions of the skeletal system.

By: Chlo? Durfee Sydney Modder Ramya Ramesh Megumi Sharma Chase Damis The Respiratory System Larynx (Voice Box) Connects pharynx to trachea Provides airway Prevents food from entering respiratory tract Produces sound Pharynx (throat) Provides passageway for respiratory and digestive tracts Tube like structure that connects nasal and oral cavities to larynx Coordinates breathing and swallowing while eating Larynx/Pharynx Larynx/Pharynx Epiglottis Blocks food and liquids from entering the trachea Spoon-like structure Epiglottis Lungs Pair of spongy, air-filled organs. Located on either side of thorax. Covered by thin tissue called pleura. Pull in oxygen and absorbs it into linings of lungs. Pushes oxygen into chambers of the heart so oxygen travels throughout the body.

Biology B3 B3.1 Exchange of materials 1.1 Osmosis Osmosis is the net movement of water particles from an area of high water concentration to an area of low water concentration across a partially permeable membrane (e.g. a cell membrane) It?s random and re quires no energy 1.2 Active transport Cells may need to absorb substances which are in short supply, i.e. against the concentration gradient. To do this they use active transport to absorb substances across partially permeable membranes Active transport requires the use of energy released in respiration Cells are able to absorb ions from dilute solutions. For example, root cells absorb mineral ions from the dilute solutions in the soil by active transport Glucose can be reabsorbed in the kidney tubules by active transport

Emma Mashburn Mr. Knapp APES April 24, 2013 Airborne Particulate Lab Follow up Questions A fine course particle is less than 2.5 micrometers in size and is easily inhaled deep into the lungs. A course particles is greater than 2.5 micrometers but smaller than 10 micrometers Fine particles can cause increased respiratory systems, decreased lung function, and aggracated asthma. Five examples of particle pollutants are soot, windblown dust, aerosols, pollen, and insect body parts.
