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.

Campbell Biology 9th edition

Chapter Forty-Two: Circulation and Gas Exchange Preface All animals must exchange substances with the environment. Unicellular animals may directly exchange with the environment. Nutrients and oxygen enter through the plasma membrane to the cytoplasm while carbon dioxide and metabolic by-products exit from the cytoplasm through the plasma membrane. Multicellular organisms cannot exchange material at the cellular level and therefore rely on specialized systems that carry out exchange with the environment and transport the material from the sites of exchange to the rest of the body. Concept One: Circulatory systems link exchange surfaces with cells throughout the body

Circulatory system

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

Cardiovascular Vocabulary Diastolic Pressure - the blood pressure (as measured by a sphygmomanometer) after the contraction of the heart while the chambers of the heart refill with blood. Arteriole - A small branch of an artery leading into capillaries. Cardiac Output - the amount of blood pumped out by the ventricles in a given period of time. Atrioventricular valve - either of two heart valves through which blood flows from the atria to the ventricles; prevents return of blood to the atrium. Bicuspid Valve - valve with two cusps; situated between the left atrium and the left ventricle. Systolic Pressure - the blood pressure (as measured by a sphygmomanometer) during the contraction of the left ventricle of the heart.

Chapter 13 - Cardiovascular SystemPRIVATE ? 13.1 Introduction (p. 329; Fig. 13.1) A. The cardiovascular system consists of the heart, and vessels, arteries, capillaries and veins. B. A functional cardiovascular system is vital for supplying oxygen and nutrients to tissues and removing wastes from them. 13.2 Structure of the Heart (p. 329; Fig. 13.2) A. The heart is a hollow, cone-shaped, muscular pump within the thoracic cavity. B. Size and Location of the Heart (p. 329) 1. The average adult heart is 14 cm long and 9 cm wide. 2. The heart lies in the mediastinum under the sternum; its apex extends to the fifth intercostal space. C. Coverings of the Heart (p. 329; Fig. 13.3) 1. The pericardium encloses the heart.

Performance task #3 1. Hypothesis: If you fertilize the ocean with iron then, it will help reduce atmospheric carbon dioxide levels. 2. Step-by-Step procedure: 1. Dissolve 7 metric tons of iron sulfate in acidic sea water.?? 2. Spew the solution into a ships propeller wash on a specific date covering a circular patch in the eddy. 3. Cover in iron in a circular path for 167 square km (0.01 grams per square meter. ? 4. Monitor the fate of the patch, off and on for 5 weeks while adding supplemental iron fertilizer after every 2 weeks to keep concentrations high enough to promote growth. ?? 5. Record the microscopic life bloomed on a data table.
