100
What blood vessels carry blood away from the heart?
Arteries
100
Put these structures in order: alveoli, trachea, bronchioles, pharynx, bronchi, larynx.
Pharynx → Larynx → Trachea → Bronchi → Bronchioles → Alveoli.
100
What two structures make up the central nervous system?
Brain and spinal cord.
100
Which brain lobe is responsible for vision?
Occipital Lobe
100
Which blood cells carry oxygen?
Red blood cells.
200
What are the four chambers of the heart?
Right atrium, right ventricle, left atrium, left ventricle.
200
Where does gas exchange take place in the lungs?
Alveoli
200
Which type of neuron carries information toward the brain and spinal cord?
Sensory neuron.
200
Which lobe is colored yellow and indicate what it is responsible for
Temporal; Hearing, language and memory
200
Which tiny blood vessels are one cell thick and allow substances to be exchanged?
Capillaries
300
What valve is located between the right atrium and right ventricle?
Tricuspid valve.
300
What happens to the diaphragm when you inhale?
It contracts and moves down, increasing lung volume.
300
These neurons carry messages on the efferent pathway
Motor neurons
300
Which brain lobe is responsible for decision-making and planning?
Frontal lobe.
300
What happens to the diaphragm when you exhale?
It relaxes and moves upward.
400
Name the four components of blood and their jobs.
Red blood cells - carry oxygen
White blood cells - fight infection
Platelets - clot blood
Plasma - the liquid part of blood.
400
What happens to oxygen and carbon dioxide at the alveoli?
Oxygen moves into the blood, and carbon dioxide moves from the blood into the alveoli.
400
What is the job of an interneuron?
Connects neurons within the brain and spinal cord, delivering decisions made in the brain and spinal cord to the motor neuron
400
What part of the brain controls balance and coordination?
Cerebellum
400
Put the reflex pathway in the correct order.
Stimulus → Receptor → Sensory neuron → Interneuron → Motor neuron → Effector → Response.
500
Trace oxygen-poor blood from the body to the lungs.
Body → Inferior/Superior vena cava → Right atrium → Tricuspid valve → Right ventricle → Pulmonary valve → Pulmonary artery → Lungs.
500
Explain how the respiratory and circulatory systems work together.
Oxygen enters the blood at the alveoli. The circulatory system carries oxygen to the body. Blood carries carbon dioxide back to the lungs, where it is exhaled.
500
What is the difference between a reflex and a voluntary response?
A reflex is automatic and happens quickly; decision made by spinal cord. A voluntary response is a conscious choice; decision made by brain and spinal cord.
500
What is the job of the myelin sheath, and what would happen if a neuron did not have it?
The myelin sheath insulates the axon and helps nerve impulses travel faster. Without it, messages would travel more slowly.
500
What happens to blood after it leaves the left ventricle?
It passes through the aortic valve, enters the aorta, and travels to the body.
