Transport and Protection CHAPTER NEW CHAPTER Transport and Protection the BIG idea Systems function to transport materials and to defend and protect the body. 3.1 The circulatory system transports materials. 3.2 The immune system defends the body. 3.3 The integumentary system shields the body. CHAPTER OUTLINE

3.1 The circulatory system transports materials. The heart, blood vessels, and blood of the circulatory system work together to transport materials from the digestive and respiratory systems to all cells. circulatory system heart blood red blood cell blood vessels The blood exerts pressure on the walls of the blood vessels and keeps the blood moving around the body. artery vein capillary SECTION OUTLINE

3.1 circulatory system The circulatory system transports materials. blood The group of organs, consisting of the heart and blood vessels, that circulates blood through the body. red blood cell artery vein capillary KEY CONCEPT SUMMARY

3.1 blood The circulatory system transports materials. A fluid in the body that delivers oxygen and other materials to cells and removes carbon dioxide and other wastes. red blood cell artery vein capillary KEY CONCEPT SUMMARY

3.1 red blood cell The circulatory system transports materials. A type of blood cell that picks up oxygen in the lungs and delivers it to cells throughout the body. red blood cell artery vein capillary KEY CONCEPT SUMMARY

3.1 artery The circulatory system transports materials. blood A blood vessel with strong walls that carries blood away from the heart. red blood cell artery vein capillary KEY CONCEPT SUMMARY

3.1 vein The circulatory system transports materials. blood A blood vessel that carries blood back to the heart. red blood cell artery vein capillary KEY CONCEPT SUMMARY

3.1 capillary The circulatory system transports materials. blood A narrow blood vessel that connects arteries with veins. red blood cell artery vein capillary KEY CONCEPT SUMMARY

The immune system defends the body. 3.2 The immune system defends the body. The immune system defends the body from pathogens. White blood cells identify and attack pathogens that find their way inside the body.The immune system responds to attack with inflammation, fever, and development of immunity. pathogen immune system antibody Pathogen Types of Pathogens Disease antigen immunity vaccine colds, chicken pox, hepatitis, AIDS, influenza, mumps, measles, rabies virus antibiotic food poisoning, strep throat, tetanus, tuberculosis, acne, ulcers, Lyme disease bacteria athlete's foot, thrush, ringworm fungus malaria, parasitic pneumonia, pinworm, lice, scabies SECTION OUTLINE parasites

3.2 pathogen The immune system defends the body. An agent that causes disease. antibody antigen immunity vaccine antibiotic KEY CONCEPT SUMMARY

3.2 immune system The immune system defends the body. pathogen immune system immune system A group of organs that provides protection against disease-causing agents. antibody antigen immunity vaccine antibiotic KEY CONCEPT SUMMARY

3.2 antibody The immune system defends the body. pathogen antibody immune system A protein produced by some white blood cells to attack specific foreign materials. antibody antigen immunity vaccine antibiotic KEY CONCEPT SUMMARY

3.2 antigen The immune system defends the body. pathogen antigen immune system A particular substance that the body recognizes as foreign and that stimulates a response. antibody antigen immunity vaccine antibiotic KEY CONCEPT SUMMARY

3.2 immunity The immune system defends the body. pathogen immunity immune system Resistance to a disease. Immunity can result from antibodies formed in the body during a previous attack of the same illness. antibody antigen immunity vaccine antibiotic KEY CONCEPT SUMMARY

3.2 vaccine The immune system defends the body. pathogen vaccine immune system A small amount of a weakened pathogen that is introduced into the body to stimulate the production of antibodies. antibody antigen immunity vaccine antibiotic KEY CONCEPT SUMMARY

3.2 antibiotic The immune system defends the body. pathogen antibiotic immune system A medicine that can block the growth and reproduction of bacteria. antibody antigen immunity vaccine antibiotic KEY CONCEPT SUMMARY

The integumentary system shields the body. 3.3 The integumentary system shields the body. The skin protects the body from harmful materials in the environment, and allows you to sense temperature, pain, touch, and vibration. integumentary system In most cases the skin is able to heal itself after injury. epidermis dermis SECTION OUTLINE

3.3 integumentary system The integumentary system shields the body. epidermis The body system that includes the skin and its associated structures. dermis KEY CONCEPT SUMMARY

3.3 epidermis The integumentary system shields the body. The outer layer of the skin. dermis KEY CONCEPT SUMMARY

3.3 dermis The integumentary system shields the body. epidermis The inner layer of the skin. dermis KEY CONCEPT SUMMARY

Structures in the circulatory system function together. red blood cell artery 1. The Heart vein 2. Blood capillary 3. Blood Vessels C. Blood exerts pressure on blood vessels. D. Blood comes in four different types. KEY CONCEPT SUMMARY

The immune system defends the body. 3.2 The immune system defends the body. II. The immune system defends the body. pathogen A. Many systems defend the body from harmful materials. immune system B. The immune system has response structures. antibody 1. White Blood Cells antigen 2. The Lymphatic System immunity C. The immune system responds to attack. 1. Nonspecific Response vaccine 2. Specific Response antibiotic 3. Development of Immunity D. Most diseases can be prevented or treated. 1. Vaccination KEY CONCEPT SUMMARY 2. Treatment

The integumentary system shields the body. 3.3 The integumentary system shields the body. III. The integumentary system shields the body. integumentary system A. Skin performs important functions. B. The structure of skin is complex. epidermis 1. Dermis and Epidermis dermis 2. Sweat and Oil Glands 3. Hair and Nails 4. Sensory Receptors C. The skin grows and heals. 1. Growth 2. Injuries and Healing 3. Protection KEY CONCEPT SUMMARY
