Explain the difference between arteries and veins. • Arteries carry blood AWAY from heart. Veins carry blood to the heart. • Arteries are larger, more muscular and elastic than veins. • Arteries carry blood under higher pressure than veins. • Veins have valves to prevent the backflow of blood. Arteries do not have valves.

Skeletal Cardiac Identify the muscle type described. • Attached to bones. • Involuntary and striated. • Lines the digestive tract and blood vessels. • Voluntary. • Only found in the heart. • Not striated and involuntary. • Branched fibers. Smooth Skeletal Cardiac Smooth Cardiac
Identify each structure in the diagram and describe its function. Skeletal muscle: moves bones Ligament: connects bones Tendon: connects muscles to bines Bone
Which statement describes ligaments? • They are made of cartilage and cushion the vertebrae. • They are made of tough, elastic tissue and join bones. • They are made of tough, inelastic tissue and connect muscles. • They are striped and controlled by the nervous system.
The tissue that cushions the vertebrae and provides flexibility to joints is known as _______. cartilage
Running to escape danger is an action that requires the nervous system to coordinate the interaction of which two body systems? (1) digestive and endocrine (2) muscular and skeletal (3) reproductive and excretory (4) circulatory and digestive
The interaction of the skeletal and muscular systems to produce locomotion is coordinated by which human body system? • circulatory • nervous (3) excretory (4) respiratory
What is bacteria an example of? Pathogen 2. Identify the structures labeled X in the diagram. Support your answer. Antibodies. They are proteins found on the surface of pathogens. X
3. Describe what occurs when this pathogen enters the body. Antibodies and memory cells are produced. Antibodies bind to the antigen to help destroy the pathogen. Memory cells remain in the blood to produce antibodies if exposed to the SAME pathogen. X
Explain the contents of a vaccine. Dead or weak PATHOGEN
How does a measles vaccine protect a child entering school against the measles? Vaccineis injected. The body produces antibodies and memory cells. Antibodies attach to antigens on the pathogen to help kill the pathogen. Memory cells remain in your blood to “remember” the pathogen.
HIV (which is a virus) It weakens the immune system so the body cannot fight pathogens well. • What pathogen causes AIDS? • What is the effect of AIDS on the body?
Infections may be caused by • mutations (2) toxic substances (3) microorganisms (4) climate changes
Which health condition is an infectious disease? (1) pneumonia caused by microorganisms (2) heart problem caused by a high-fat diet (3) lung cancer caused by smoking (4) eye damage caused by ultraviolet light
Scurvy is a disease that sailors often got on long voyages. It was discovered that scurvy could be prevented by eating oranges and lemons. This suggests that scurvy is a disease caused by • exposure to sea air (2) a microorganism (3) a nutritional deficiency (4) lack of exercise

Identify the difference between the central nervous system and the peripheral nervous system. CNS consists of the brain and spinal cord. (interneurons) PNS consists of all nerves that extend away from the brain and spinal cord (sensory and motor neurons)
Neuron • Identify the structure below. • Label all structures. A B D E C
Impulse 3. Identify the message that travels through neurons. 4. Describe the nature of this message. Electrical and chemical
In a simple spinal reflex, the pathway for an impulse is along a sensory neuron directly to a motor neuron through (1.) a receptor (2.) an interneuron (3.) an effector (4.) the brain
Neurons that carry messages toward the CNS (brain and spinal cord) are called sensory neurons
Neurons that carry messages away the CNS (brain and spinal cord) are called Motor neurons
Why are reflexes much faster than a normal response? The impulse only travels to the spinal cord, not the brain.
Insulin and glucagon are hormones that affect blood sugar levels. The diagram below shows the feedback system used by the human body to increase and decrease blood sugar levels. This feedback system is one way that the human body • circulates gases (3) destroys viruses (2) maintainsequilibrium (4) transports nutrients
