Skeleton

• What is the function of the skeleton?
• Name the major bones of the arm and leg.
• Why is the skeleton important to red blood cells?
• Compare and contrast the forearm of a rat and a bat. Why is one better at flying, and the other is better at running?
• What is different between the teeth of carnivours, herbivours, and insectivours?

Nervous System

• What is the function of the nervous system?
• What is a neuron?
• Name and describe the five mechanoreceptors involved in touch.
• Name and describe the two visualreceptors. Where are they found?
• Name and describe the chemoreceptors involved in taste.
• Describe how the nose is involved in taste, using examples.
• What are neurotransmiters?
• Through which part of a neuron does neurotransmiter enter the nerve cell?
• Through which part of a neuron does neurotransmiter leave the nerve cell?
• What insulates neurons? Does that insulation help transmit neurotransmiters faster? Why?
• How is sound transmited from the air, through the middle ear, and then through the inner ear?

Cardiovascular System

• Compare and contrast the pulmonary and the systemic circuits of the cardiovascular system.
• In which circuit is blood oxygenated?
• In which circuit is oxygenated blood delivered to the body?
• Name the chambers of the heart.
• Name the four major heart valves, and describe what each valve specifically do.
• Describe the pathway of blood through the heart.
• What is the job of arteries?
• What is the job of veins?
• What is the job of capillaries?
• Compare and contrast the physical structure of arteries, veins, and capillaries.

Blood

• Be able to tell the difference between blood cells and blood plasma.
• Name the two major types of blood cells, and describe what they do.
• What is the name of the protein involved in carrying oxygen and carbon dioxide? How many can it carry at one time.
• What determines whether hemoglobin will pick up oxygen and drop off carbon dioxide, or whether hemoglobin will do the exact opposite?
• Be able to compare the size of a red blood cell and hemoglobin.

Respiratory System

• What are the four major organs (parts) of the respiratory system?
• What is the function of the trachea and bronchi?
• Why does air exchange occur in the alveoli?
• What benefits does the nasal cavity provide the respiratory system?
• Which lung is larger?
• How many lobes does the right and left lung have?
