Objective 18-20 EOT G6

How is blood transported throughout the body?

• Through the nervous system

• Through the digestive system

• Through the respiratory system

• Through the circulatory system

What are the parts of the circulatory system and their function?

• Pancreas - regulate blood sugar, Spleen - store blood, Bladder - store blood, Thymus - produce blood cells

• Muscles - produce blood, Skin - protect blood, Bones - store blood, Eyes - see blood

• Brain - controls blood flow, Stomach - digests blood, Liver - stores blood, Intestines - absorb blood nutrients

• Heart - pumps blood, Lungs - exchange oxygen and carbon dioxide, Blood vessels - transport blood, Kidneys - filter blood

What is the difference between an open circulatory system and a closed circulatory system?

• Open system has blood flowing in vessels, closed system has blood flowing in open spaces

• Open system has blood flowing in open spaces, closed system has blood flowing in vessels

• Open system has no blood, closed system has blood flowing in vessels

• Open system has blood flowing in vessels, closed system has no blood

How does the human eye see?

• Through the circulatory system

• Through the respiratory system

• Through the digestive system

• Through the nervous system

What are the parts of the human eye and their function?

• Cornea - focuses light, Retina - detects light, Optic nerve - sends signals to the brain, Lens - focuses light

• Liver - processes light, Stomach - digests light, Intestines - absorb light, Kidneys - filter light

• Tongue - tastes light, Eardrum - hears light, Nose - smells light, Skin - feels light

• Lungs - breathe light, Heart - pump light, Brain - think about light, Muscles - move light

What are the parts of the respiratory system and their function?

• Nose - filters air, Lungs - exchange oxygen and carbon dioxide, Trachea - transport air, Diaphragm - controls breathing

• Stomach - digests air, Liver - processes air, Intestines - absorb air, Kidneys - filter air

• Heart - pumps air, Brain - controls air flow, Skin - protects air, Muscles - move air

• Cornea - focuses air, Retina - detects air, Optic nerve - sends signals to the brain, Lens - focuses air

What is the difference between voluntary and involuntary muscles?

• Voluntary muscles are controlled by the nervous system, involuntary muscles are not controlled by the nervous system

• Voluntary muscles are not controlled by the nervous system, involuntary muscles are controlled by the nervous system

• Voluntary muscles are found in the digestive system, involuntary muscles are found in the circulatory system

• Voluntary muscles are found in the respiratory system, involuntary muscles are found in the skeletal system

Which type of tissue do you think moves blood in open and closed
circulatory systems?

• nervous tissue

• vascular tissue

• dermal tissue

• small intestine

1. What happens to oxygen in the lungs during the breathing process?

• • A. It is converted into carbon dioxide

• • B. It is released into the atmosphere

• • C. It moves into the blood

• • D. It combines with nitrogen in the air

In the path of light entering the eye, what is the correct order of structures?

• • A. Pupil, retina, optic nerve, lens, cornea

• • B. Cornea, lens, retina, optic nerve, pupil

• • C. Optic nerve, cornea, lens, pupil, retina

• • D. Retina, pupil, lens, cornea, optic nerve
