Skeletal System Your skeleton has five major functions.  •  It provides shapeSkeletal System Your skeleton has five major functions. • It provides shape and support • Enables you to move • Protects your internal organs • Produces blood cells • Stores certain materials until your body needs them

Major Organs of the Skeletal System • Bones • Tendons connect bones to muscles.Major Organs of the Skeletal System • Bones • Tendons connect bones to muscles. • Ligaments connect bone to bone. • Cartilage cushions places where bones connect and offers flexibility.

Muscular System Your muscles control all movements of the body tissues,  organs andMuscular System Your muscles control all movements of the body tissues, organs and bones.

Major Tissues of the  Muscular System Your body has three types of MuscleMajor Tissues of the Muscular System Your body has three types of Muscle tissue. • skeletal muscle • smooth muscle • cardiac muscle

Circulatory System aka Cardiovascular System The main functions is to transport • Oxygen •Circulatory System aka Cardiovascular System The main functions is to transport • Oxygen • Nutrients • Waste throughout the body

The main parts of the Circulatory System are:  • Heart • Blood VesselsThe main parts of the Circulatory System are: • Heart • Blood Vessels • Blood

Respiratory System Your respiratory system moves oxygen from the outside environment into your body.Respiratory System Your respiratory system moves oxygen from the outside environment into your body. It also removes carbon dioxide and water from your body.

The Main Parts of the Respiratory system are:  • Nose • Mouth •The Main Parts of the Respiratory system are: • Nose • Mouth • Trachea • Lungs • Diaphragm

The Digestive System • The main functions of the digestive system  • BreaksThe Digestive System • The main functions of the digestive system • Breaks down food into molecules the body can absorb. • Passes these molecules into the blood to be carried throughout the body. • Eliminates solid wastes from the body.

The Main Parts of the Digestive System are: 19 The Main Parts of the Digestive System are:

The Excretory System Your excretory system collects wastes produced by cells and removes theseThe Excretory System Your excretory system collects wastes produced by cells and removes these wastes from your body. The removal process is known as excretion. • Each kidney is about 4 ½ inches long • Weight is 4 – 6 ounces • The urine output varies from 1 to 2 liters per day.

The Main Parts of the Excretory System 21 The Main Parts of the Excretory System

Integumentary System (it’s your skin) Your Skin has many important functions:  • CoversIntegumentary System (it’s your skin) Your Skin has many important functions: • Covers body and prevents water loss. • Protects body from injury and infection. • Helps regulate body temperature. • Eliminate wastes • Gathers information about the environment • Produce vitamin

Immune System • It’s role is to protect you from foreign invaders. Special cellsImmune System • It’s role is to protect you from foreign invaders. Special cells react to each kind of pathogen with defensive tactics targeted specifically at that type of pathogen. • A pathogen is a bacterium, virus, or other microorganism that can cause disease.

Specialized Immune System Cells • White blood cells that target specific pathogens are calledSpecialized Immune System Cells • White blood cells that target specific pathogens are called lymphocytes. • T-cells and B-cells are two major types of lymphocytes. Each type has a specific job. T- Cells B- Cells

What are Antibodies?  • Antibodies are special proteins that recognize and defeat invadingWhat are Antibodies? • Antibodies are special proteins that recognize and defeat invading pathogens. • Antibodies are made by the B-cells. • Once a pathogen is encountered by the B-cells it memorizes it and next time it encounters the pathogen it will have antibodies ready to fight the pathogen.

What are Antigens? An antigen is any substance that when introduced into the bodyWhat are Antigens? An antigen is any substance that when introduced into the body stimulates the production of an antibody immune response. Antigens include: Toxins Bacteria Foreign blood cells Cells of transplanted organs.

What is Immunity?  • Immunity is a state in which the body hasWhat is Immunity? • Immunity is a state in which the body has sufficient defenses to fight infection, disease or invasion by pathogens. • Non- Specific Immunity refers to the defenses that are in place at all times and are not specific to the pathogen to which the system is responding. • Skin, mucous membranes, hairs in nose and ears, enzymes in mouth and tears in eyes.

Specific Immunity is a specific antibody response to the pathogen and has been acquiredSpecific Immunity is a specific antibody response to the pathogen and has been acquired in one of several ways. • Antibodies were transferred from mother to fetus across the placenta. • Antibodies were transferred through breast milk from mother to child. • Antibodies were built up due to prior exposure to the pathogen. • Antibodies were be built up through a vaccination process.

What is a Vaccination?  • Most vaccines contain a little bit of aWhat is a Vaccination? • Most vaccines contain a little bit of a disease germ that is weak or dead. Vaccines do NOT contain the type of germ that makes you sick. • Having this little bit of the germ inside your body makes your body’s immune system build antibodies to it. • Vaccines can be administered by a needle, mouth and some thorough a nasal spray. • In the US children are vaccinated before they can enter school for: Measles, Mumps, Rubella, Pertussis, Hepatitis B, Diphtheria, and Tetanus

Lymphatic System The lymphatic system is an extensive drainage network that helps keep bodilyLymphatic System The lymphatic system is an extensive drainage network that helps keep bodily fluid levels in balance and defends the body against infections. It filters out organisms that cause disease, produces certain white blood cells and generates antibodies

 • It is made up of a network of lymphatic vessels that carry • It is made up of a network of lymphatic vessels that carry lymph — a clear, watery fluid that contains protein molecules, salts, glucose, urea, and other substances — throughout the body. • It works closely with the immune system and the circulatory system. • The Spleen stores many of the white blood cells needed for the immune response. Major Parts of the Lymphatic System

Endocrine System 1. The endocrine system is a collection of ductless glands that secreteEndocrine System 1. The endocrine system is a collection of ductless glands that secrete special proteins called hormones. 2. The glands release the hormones into the bloodstream and they travel to the target cells or organs. 3. The main function of the endocrine system is to maintain a stable environment within the body or homeostasis. 4. The hormones also help the body to regulate: Growth Sexual development Metabolism Sugar, salt and fluid levels in the blood
