A&P Chapter 12 Flashcards
A bacterial infection of the urethra
Urethritis
The organs that control the discharge of certain waste materials filtered from the blood and excreted as urine
Urinary System
U-shaped portion of the renal tubule that extends from the proximal to the distal convoluted tubule
Loop of Henle
The structure of the kidney that supplies blood to the glomerulus
Afferent Arteriole
One of three parts of the male urethra; it extends from the prostate gland to the base of the penis
Membranous Urethra
The blood vessel connecting the kidneys to the inferior vena cava
Renal Vein
One of two complex sections of a nephron; it includes an enlargement at the end called the glomerular capsule
Proximal Convoluted Tubule
The structural and functional units of the kidney that form urine, composed of the glomerulus, the glomerular capsule, the proximal convoluted tubule, the loop of Henle, and the distal convoluted tubule
Nephrons
One of many complex, interconnected capillary networks that branch off of efferent arterioles
Peritubular Capillary
Two retroperitoneal organs that excrete the end products of metabolism as urine and regulate the body’s salt and water content
Kidneys
A procedure in which an artificial kidney external to the body is used to purify the blood
Hemodialysis
A funnel-shaped sac inside the renal sinus that is subdivided into major and minor calyces (tubes)
Renal Pelvis
The final product of tubular reabsorption and secretion; it is a clear, yellow fluid that carries wastes out of the body
Urine
In females, a small, cylindrical mass of erectile tissue and nerves located at the anterior junction of the labia minora, similar to the glans penis of the male
Clitoris
The rate at which blood is filtered through the glomerula
Glomerular Filtration Rate
The initial-filtering component of the nephron
Renal Corpuscle
A canal in a female reproductive system extending from the uterus to the external orifice. It allows for the discharge of menstrual flow, receives the penis during sexual intercourse, and serves as the birth canal
Vagina
A sac-like structure that surrounds the glomerulus, from which it receives filtered fluid
Glomerular Capsule
Cavity formed by the hilum that is filled with fat and connective tissue
Renal Sinus
The process that moves substances from the blood in the peritubular capillary into the renal tubule
Tubular Secretion
Solid crystalline masses formed in the kidney that may become trapped anywhere along the urinary tract
Kidney Stones
Structure formed at the site where the efferent arteriole and distal convoluted tubule meet; also called a juxtaglomerular complex; plays an important role in regulating fluid balance
Juxtaglomerular Apparatus
