Respiratory System
These are the tiny air sacs in the lungs where gas exchange (oxygen and carbon dioxide) occurs.
alveoli
This protein produced by B cells binds to pathogens and helps neutralize them.
antibody
This term refers to the uncontrolled growth and spread of abnormal cells in the body.
cancer
This muscular tube connects the mouth to the stomach and is involved in the process of swallowing.
esophagus
This type of cell in the nervous system carries electrical impulses and is the functional unit of the nervous system.
neuron
This is the tube that connects the larynx to the bronchi and serves as the main passageway for air to reach the lungs.
trachea
This type of immunity results from exposure to a pathogen or from vaccination, where the body develops memory cells to fight future infections.
This cancer develops in the cells of the prostate gland, typically in men over the age of 50.
prostate cancer
This type of muscle contraction moves food through the digestive tract, from the esophagus to the intestines.
peristalsis
This condition is characterized by the progressive loss of memory, thinking skills, and the ability to carry out daily activities, often caused by plaques and tangles in the brain.
Alzheimer's disease
This gas is carried out of the blood into the alveoli to be exhaled.
carbon dioxide
This part of the immune system includes the spleen, lymph nodes, and bone marrow, and helps produce and store immune cells.
lymphatic system
This antibiotic-resistant bacteria is often responsible for skin infections, pneumonia, and bloodstream infections, and it is commonly found in healthcare settings.
MRSA
This condition involves the backward flow of stomach acid into the esophagus, causing heartburn and possible damage to the esophageal lining.
GERD
This disorder involves the breakdown of the protective covering of nerve fibers in the central nervous system, often leading to a wide range of neurological symptoms.
MS
This chronic condition is characterized by inflamed and narrowed airways, leading to difficulty breathing and wheezing.
asthma
These white blood cells engulf and digest pathogens, dead cells, and other debris.
phagocytes
This bacterial infection is commonly associated with long-term antibiotic use, leading to diarrhea, abdominal cramping, and potentially severe complications.
C-diff
This part of the digestive system is responsible for the reabsorption of water and the formation of stool.
large intestine or colon
This disorder involves a sudden disruption of blood flow to the brain, leading to neurological deficits.
This component of blood binds to oxygen in the lungs and transports it to tissues throughout the body.
hemoglobin
These cells "remember" previous infections and allow for a faster immune response if the same pathogen invades again.
memory cells
This bacterial infection affects the lungs and is spread through airborne droplets. Symptoms include persistent coughing and chest pain.
TB
This part of the digestive system is where the majority of nutrient absorption takes place.
small intestine
This part of the nervous system is responsible for the "fight or flight" response, preparing the body for stressful situations.
Sympathetic nervous system
