Vision & the Brain
What part of the brain processes visual information from the eyes?
Occipital lobe
What are the three main types of blood vessels?
Arteries, veins, capillaries
What two body systems work together during gas exchange?
Respiratory & circulatory
DOUBLE JEOPARDY: What are the three layers of skin?
Epidermis, dermis, subcutaneous tissue
What are the two main types of immunity?
Innate & acquired
What structure carries visual signals from the retina to the brain?
Optic nerve
What is the function of capillaries?
Exchange of gases, nutrients, and waste
DOUBLE JEOPARDY: What happens to oxygen after it enters the alveoli?
It diffuses into capillaries and binds to red blood cells.
How does sweating help regulate body temperature?
Cools the body through evaporation
What are the cellular components of the immune system?
White blood cells: B-cells, T-cells, macrophages
DOUBLE JEOPARDY: What part of the eye films along back of eye containing nerve cells that are sensitive to light & trigger impulses that pass through optic nerve to brain?
the retina
How do arteries differ structurally from veins?
Thicker walls, more muscle to handle pressure
What test measures lung capacity?
Spirometry
What role do hair follicles and sweat glands play in homeostasis?
Regulate temperature and protect the body
What is an antigen?
A foreign molecule that triggers an immune response
How do the cornea and lens work together?
They focus light on the retina.
What tool is used to detect the electrical activity of the heart?
EKG/ECG
List one way to improve and one way to harm lung function.
Exercise; smoking
What is meant by "immune privilege" in the skin or eyes?
Reduced inflammatory response to prevent damage
DOUBLE JEOPARDY: How do vaccines prepare the immune system for future infections?
They stimulate memory cells to recognize the pathogen.
How would a damaged optic nerve affect vision?
It would impair the brain’s ability to receive and process visual information.
DOUBLE JEOPARDY : Name a medical intervention used to restore blood flow in blocked vessels.
Stent, bypass surgery, angioplasty
What is the difference between the conducting zone and the respiratory zone?
Conducting Zone: This is like the air’s highway. It includes structures like the nose, pharynx, larynx, trachea, bronchi, and bronchioles. Its job is to move, warm, moisten, and filter air—but no gas exchange happens here.
Respiratory Zone: This is where the real action happens—gas exchange! It includes the respiratory bronchioles, alveolar ducts, and alveoli. Oxygen moves into the blood, and carbon dioxide moves out.
So basically:
👉 Conducting = air delivery system
👉 Respiratory = gas exchange hub
How does skin act as a barrier to infection?
Blocks pathogens from entering the body
What happens during a second exposure to an antigen?
Faster, stronger immune response due to memory cells
