The skeletal system relies on this system to produce Vitamin D, which is essential for calcium absorption.
The Integumentary (Skin) system?
This chronic condition occurs when the pancreas fails to produce enough insulin, affecting blood sugar.
Diabetes
These tiny air sacs in the lungs are the site where gas exchange actually occurs.
Alveoli
This is the body's largest organ and its first line of defense against pathogens.
Skin
This is the largest internal organ in the human body by weight and size.
Liver
These two systems work together to provide the body with oxygen and remove carbon dioxide.
What are the Respiratory and Circulatory systems?
This respiratory disease causes the airways to narrow and swell, often triggered by exercise or allergies.
Asthma
This is the primary organ responsible for filtering toxins from the blood and producing bile.
Liver
These blood cells are the "soldiers" of the immune system, identifying and destroying invaders.
White blood cells
This is the strongest muscle in the human body relative to its size, located in the jaw and used for chewing.
Masseter
When you eat, the muscular system moves food down the esophagus using this wave-like motion.
Peristalsis
This "silent" cardiovascular condition is characterized by consistently high force of blood against artery walls.
Hypertension
This type of muscle tissue is found only in the heart and never gets tired.
Cardiac muscle
This system of vessels and nodes returns leaked fluid to the blood and filters out bacteria.
Lymphatic system
This is the longest and strongest bone in the human body, located in the upper leg.
Femur
These two systems coordinate to trigger the "fight or flight" response during a stressful event.
The Nervous and Endocrine systems
An autoimmune disorder where the immune system attacks the joints, causing inflammation.
Rheumatoid Arthritis
These chemical messengers are secreted by glands directly into the blood to regulate body functions.
Hormones
This is a substance used to stimulate the production of antibodies and provide immunity against a disease.
Vaccine
These are the smallest bones in the human body, found deep inside the ear to help with hearing.
Ossicles
The kidneys (Excretory) help the Circulatory system by regulating this, which prevents heart strain.
Blood pressure
This neurological disorder is caused by a loss of dopamine-producing brain cells, leading to tremors.
Parkinson’s Disease
The basic functional unit of the kidney that filters waste to create urine.
Nephron
These Y-shaped proteins are produced by B-cells to "tag" specific pathogens for destruction.
Antibodies
This is the only organ in the human body that is capable of completely regenerating itself from a small fraction of its original size.
