Reproduction- what's your function?
It is in this stage of spermatogenesis that the cells first become haploid.
What is the secondary spermatocyte stage?
This is the primary waste product measured in BUN and urine to evaluate kidney function.
What is urea?
This diploid stem cell goes through mitosis to begin the process of spermatogenesis in the seminiferous tubules?
What is a spermatogonium?
A patient whose intrapleural pressure equals their intrapulmonary pressure is likely suffering from this.
What is a collapsed lung / pneumothorax?
This type of nephron has its corpuscle located in the outer cortex and features a short loop of henle.
What is a cortical nephron?
These cells in the testis are stimulated by LH to make and secrete testosterone.
What are interstitial (Leydig) cells?
To calculate renal plasma clearance, you multiply urine concentration by urine flow rate, and then you divide by this.
What is plasma concentration?
These are the products of oogenesis.
What are 1 mature ovum 3 nonfunctional polar bodies?
This physical property of the lung will be high in an emphysema patient, but low in a fibrosis patient.
What is lung compliance?
The minimum plasma concentration of a substance that results in the substance spilling over into the urine because transporters are saturated.
What is the renal threshold?
Fertilization of the secondary oocyte typically takes place in this location within the female reproductive tract.
What is the ampulla of the uterine (fallopian) tube?
When blood glucose exceeds this limit, the transport maximum (Tm) of PCT symporters is overwhelmed, causing glycosuria.
What is the renal threshold?
This pituitary hormone surge causes the secondary oocyte to resume and complete meiosis 1.
What is LH?
This effect explains how the binding of oxygen to hemoglobin causes it to release CO2 in the lungs.
What is the Haldane effect?
This hormone primarily acts on principal cells to insert aquaporins.
What is ADH/Vasopressin?
Wolffian ducts would degenerate and regress in the absence of this gene.
What is the SRY gene?
An abnormally low GFR and an elevated plasma creatinine level indicates this medical emergency.
What is renal failure?
This specific stage of meiosis is where primary oocytes remain dormant in the ovary from fetal development until puberty.
What is Prophase 1?
This group of neurons in the medulla are primarily responsible for integrating sensory input and driving forced expiration and inspiration.
What is the VRG?
An autoregulation mechanism of the kidney in which smooth muscle of the afferent arteriole contracts in response to being stretched by high blood pressure.
What is the myogenic mechanism?
This is the primary evolutionary advantage of sexual reproduction and gamete production, compared to asexual reproduction.
What is genetic variation?
In an alveolar ventilation problem where TV= 500 mL, Dead Space= 150 mL, and RR= 12 breaths/min, this is the final AVR calculation.
What is 4200 mL/min?
What are Sertoli cells?
This term refers to the volume of air remaining in the lungs after a maximum forceful expiration.
What is residual volume?
This specialized vascular network runs parallel to the long loops of henle and plays a crucial role in preserving the medullary osmotic gradient.
What is the vasa recta?
