Takes the light your eye receives and changes it into electrical signals that your brain can understand. | Retina |
A clear disc located behind the iris that flips and focuses light onto the retina | Lens |
A nerve that carries messages from the retina to the brain | Optic Nerve |
A clear gel like substance that gives the eye its shape | Vitreous Humor |
The colored part of your eye with muscles that control the size and shape of the pupil | Iris |
A type of cell that allows the eye to sense color | Cones |
A type of cell that allows the eye to sense black, white and shades of gray. | Rods |
This disease, often linked to increased intraocular pressure, damages the optic nerve and can lead to permanent vision loss if untreated. It is commonly associated with older adults | Glaucoma |
This condition, which causes a clouding of the eye’s natural lens, is often age-related but can also occur as a result of trauma, genetics, or long-term exposure to ultraviolet light. | Cataract |
This common refractive error of the eye is caused by an irregular shape of the cornea or lens, leading to blurred or distorted vision. | Astigmatism |
This system is responsible for the body's movement and posture. | Muscular System |
What system is responsible for the body's chemical messaging? | Endocrine System |
This system filters blood and removes waste products. | Urinary System |
What system breaks down food into smaller, absorbable nutrients that the body can use for energy, growth, and repair | Digestive System |
Controls other systems, responds to internal and external changes, and transmits information to the brain | Nervous System |
Provides oxygen to the body's cells by exchanging gases between air and blood | Respiratory System |
Supports the body and all of its systems, and protects fragile organs inside the body | Skeletal System |
Collects excess fluid from tissues and transports it to the bloodstream. Tonsils belong to this system. | Lymphatic System |
A butterfly-shaped gland located in the front of your neck that produces hormones crucial for regulating your body's metabolism, impacting functions like heart rate, body temperature, and energy levels. | Thyroid |
Primary building block of your body's skin, muscles, bones, tendons and ligaments, and other connective tissues. Requires Vitamin C for synthesis. | Collagen |
These connect bones to other bones, providing stability to joints. Primarily function to limit excessive movement and maintain joint structure. ACL tears are a common knee injury to this structure | Ligaments |
A protein found in red blood cells that carries oxygen throughout the body. It is made up of four subunits. Plays a role in regulating blood pH and maintaining blood pressure. | Hemoglobin |
Name the three bones found in the ear. Smallest bone found in the human body. | hammer, anvil, stirrup (smallest) |
The name of a life-threatening condition that occurs when the body has an extreme response to an infection and releases chemicals into the bloodstream that cause inflammation and eventually organ damage or even death. | sepsis (or septicemia) |
The two airways branching off of the trachea into the lungs | bronchi or bronchial tubes |
This organ stores bile produced by the liver until its release into the small intestine during digestion. | gall bladder |
The two bones that make up the lower leg in humans and form a strong, stable structure that supports the body's weight and enables movement of the lower leg and foot. | tibia and fibula |
This hormone stimulates the cells in the body to absorb glucose from the bloodstream. | insulin |
Bundles of white fibrous connective tissue in the human body that attaches a muscle to a bone. | tendon |
Histidine, leucine, lysine, and tryptophan are some of the essential forms of what organic compounds that a human obtains from food? | amino acids |
Sphenoid, maxillary, frontal, and ethmoid are the four pairs of what in the human head? | sinuses |
Name the elongated ridges on the floor of each lateral ventricle of the brain that is thought to be the center of emotion, memory, and the autonomic nervous system. | hippocampus |
What valve in the heart acts as a one-way gate, letting blood flow from the left atrium to the left ventricle? | mitral valve |
Small structures that play a crucial role in maintaining cellular health by breaking down waste materials, recycling cellular components, and defending against foreign invaders. | lysosomes |
