Ur-ine Good Hands
This noninvasive measurement represents the quantity of glomerular filtrate formed in all nephrons of both kidneys per minute, typically 125 ml/min.
What is Glomerular Filtration Rate (GFR)?
This temporary endocrine gland forms from a ruptured Graafian follicle and is responsible for progesterone dominance in the secretory phase.
What is the Corpus Luteum?
This law states that the heart will pump all the blood that returns to it; increased stretch (preload) leads to increased force of contraction.
What is the Frank-Starling Law of the Heart?
This phospholipid substance, produced by Type II alveolar cells, reduces surface tension to prevent alveolar collapse (atelectasis).
What is Pulmonary Surfactant?
In this metabolic state, the arterial pH is below 7.35, causing the central nervous system to become less excitable, potentially leading to coma.
What is Acidosis?
This intrinsic "stretch reflex" mechanism causes the afferent arteriole to constrict when blood pressure rises and dilate when it drops.
What is the Myogenic Mechanism?
The process through which mature female gametes are formed; it begins during fetal life but is not completed until fertilization.
What is Oogenesis?
Calculated as Stroke Volume * Heart Rate, this value represents the volume of blood pumped by one ventricle in one minute.
What is Cardiac Output (CO)?
This term refers to the volume of air moved into or out of the lungs during a single normal, quiet breath.
What is Tidal Volume?
When the respiratory system causes a pH imbalance, the kidneys compensate by altering the reabsorption of this specific buffer.
What is Bicarbonate (HCO3-)?
These specialized osmoreceptor cells in the distal tubule are sensitive to NaCl concentration and can trigger vasoconstriction or vasodilation of the afferent arteriole.
What are Macula Densa cells?
Found in the seminiferous tubules, these cells form a protective barrier for developing sperm and secrete androgen-binding protein.
What are Sertoli cells?
These pressure-sensitive receptors in the carotid sinus and aortic arch provide rapid, short-term regulation of blood pressure.
What are Baroreceptors?
According to this effect, an increase in PCO2 or a decrease in pH causes hemoglobin to have a lower affinity for oxygen, shifting the dissociation curve to the right.
What is the Bohr Effect?
This clinical triad of hypertension, edema, and proteinuria occurs during pregnancy and requires close monitoring to prevent seizures.
What is Preeclampsia?
This hormonal cascade is triggered when the juxtaglomerular cells release Renin in response to low renal perfusion.
What is the Renin-Angiotensin-Aldosterone System (RAAS)?
This condition, characterized by foci of endometrial tissue found outside the uterus, causes significant pain and potential infertility.
What is Endometriosis?
On an ECG, this specific wave represents ventricular depolarization.
What is the QRS Complex?
These primary chemical regulators of respiration are located in the medulla oblongata and are most sensitive to changes in H+ concentration in the CSF.
What are Central Chemoreceptors?
Secreted by the kidney in response to low PO2, this hormone stimulates the bone marrow to increase red blood cell production.
What is Erythropoietin (EPO)?
In this clinical syndrome, a patient loses large amounts of protein in the urine, leading to hypoalbuminemia, generalized edema, and hyperlipidemia.
What is Nephrotic Syndrome?
A medical emergency occurring most often between ages 8-18, involving the twisting of the spermatic cord and requiring immediate surgery to prevent necrosis.
What is Testicular Torsion?
This clinical state occurs when the heart is unable to pump enough blood to meet the metabolic demands of the body, often leading to pulmonary or peripheral edema.
What is Heart Failure?
This chronic obstructive pulmonary disease is characterized by the destruction of alveolar walls and a permanent enlargement of air spaces, leading to "air trapping."
What is Emphysema?
The renal enzyme that converts 25-hydroxycholecalciferol into its final active form, 1,25-dihydroxyvitamin D, is controlled by this hormone.
What is Parathyroid Hormone (PTH)?
