Diseases
This chronic respiratory disease is characterized by airway inflammation and bronchoconstriction, often triggered by allergens or exercise.
What is Asthma?
The universal blood donor type for red blood cells.
What is O-?
During depolarization of a neuron, this ion moves rapidly into the cell through voltage-gated channels.
What is sodium (Na⁺)?
This is the liquid portion of blood after clotting factors have been removed.
What is serum?
This electrical event on an ECG represents atrial depolarization
What is the P wave?
This metabolic disorder is marked by hyperglycemia due to insulin resistance and is commonly associated with obesity.
What is Type 2 Diabetes Mellitus?
This instrument is used to measure blood pressure noninvasively.
What is a sphygmomanometer?
This type of epithelial tissue is specialized for diffusion and is found in the alveoli of the lungs.
What is simple squamous epithelium?
This hormone increases water reabsorption in the collecting duct by inserting aquaporin-2 channels.
What is ADH (antidiuretic hormone)?
Secreted by the zona glomerulosa, this hormone’s primary function is to increase sodium reabsorption and potassium excretion in the distal nephron
What is aldosterone?
This genetic disorder, caused by a mutation in the CFTR gene on chromosome 7, leads to thick mucus secretions, recurrent pulmonary infections, pancreatic insufficiency, and elevated sweat chloride levels.
What is Cystic Fibrosis?
This benign epithelial tumor is often caused by HPV types 6 and 11 and commonly appears as a raised, cauliflower-like lesion on the skin or mucous membranes.
What is a wart (verruca)?
These small channels connect lacunae and allow osteocytes to exchange nutrients and signals.
What are canaliculi?
This phase of the cardiac cycle occurs when ventricular pressure exceeds atrial pressure but is still less than arterial pressure.
What is isovolumetric contraction?
What does COPD stand for?
What is Chronic Obstructive Pulmonary Disease?
This chronic inflammatory bowel disease can affect any part of the gastrointestinal tract, commonly the terminal ileum, and is characterized by skip lesions and transmural inflammation.
What is Crohn’s Disease?
This vitamin deficiency can cause scurvy, leading to bleeding gums, bruising, and impaired wound healing.
What is Vitamin C deficiency?
This protein binds calcium in skeletal muscle and shifts tropomyosin to expose myosin-binding sites on actin.
What is troponin?
This portion of the nephron is most responsible for maintaining the medullary osmotic gradient.
What is loop of Henle?
This physiological buffer system is the primary extracellular mechanism for maintaining blood pH, involving HCO₃⁻ and CO₂.
What is the bicarbonate buffer system?
This neurodegenerative disorder is caused by degeneration of dopaminergic neurons in the substantia nigra, leading to bradykinesia, resting tremor, rigidity, and postural instability.
What is Parkinson’s Disease?
This gram-negative rod is lactose-fermenting, often found in the colon, and is the most common cause of urinary tract infections in otherwise healthy adults.
What is Escherichia coli (E. coli)?
In endochondral ossification, this structure serves as the initial template that is gradually replaced by bone.
What is a hyaline cartilage model?
"This intrinsic property of cardiac muscle allows it to increase stroke volume in response to increased venous return, primarily through the length-dependent activation of actin-myosin crossbridges."
What is the Frank-Starling mechanism?
This renal mechanism, involving macula densa sensing of tubular NaCl, adjusts afferent arteriolar tone via paracrine signaling to maintain glomerular filtration rate despite fluctuations in systemic blood pressure
What is tubuloglomerular feedback?
