Juxtamedullary Nephron

Front

In mammals and birds, a nephron with a hoop of henle that extends far into the medulla

Back

The glomerulus

Front

Where does filtration occur?

Back

The proximal tube of the nephron

Front

Where does water reabsorption take place in the kidney?

Back

Aldosterone

Front

Aid in conservation of sodium, secretion of potassium, and water retention

Back

Renal Medulla

Front

The inner portion of the vertebrate kidney (beneath the renal cortex)

Back

Distal Tubule

Front

In the vertebrate kidney, the portion of a nephron that helps refine filtrate and empties it into a collecting duct

Back

Renal Pelvis

Front

The funnel-shaped chamber that receives processed filtrate from the vertebrae kidney's collecting ducts and is drained by the ureter

Back

Vasa Recta

Front

The capillar system in the kidney that serves the loop of henle

Back

Afferent Arteriole

Front

In the kidney, the blood vessel supplying a nephron

Back

The distal tubule

Front

Where does the secretion of hydrogen ions take place

Back

Efferent Arteriole

Front

In the kidney, the blood vessel draining a nephron

Back

Filtration, Reabsorption, Secretion, Excretion

Front

What are the 4 functions of the excretory system?

Back

Nephron

Front

A tubular excretory unit of the vertebrate kidney

Back

Renal Artery

Front

The blood vessels that bring blood to the kidney

Back

Cortical Nephrons

Front

In mammals and birds, a nephron with a loop of henle located almost entirely in the renal cortex

Back

Collecting Duct

Front

The location in the kidney where processed filtrate, called urine, is collected from the renal tubules

Back

Renal Capsule

Front

A tough, fibrous layer surrounding the kidney which is covered by a layer of adipose tissue; provides protection from trauma and damage

Back

Distal is closest to the spine/center of the body and Proximal is farthest away from the spine/center of the body

Front

Proximal vs. Distal tubule

Back

Peritubular Capillaries

Front

One of the tiny blood vessels that form a network surrounding the proximal and distal tubules in the kidney

Back

Urochrome

Front

What makes urine yellow?

Back

Ureter

Front

A duct leading from the kidney to the uinary bladder

Back

Urinary Bladder

Front

The pouch where urine is stored prior to elimination

Back

Vasopressin, Aldosterone, and Angiotensin

Front

What are the 3 hormones that regulate kidney function?

Back

Bowman's Capsule

Front

A cup shaped receptacle in the vertebrate kidney that is the initial expanded segment of the nephron where the filtrates enters from the blood

Back

Renal Cortex

Front

The outer portion of the vertebrate kidney

Back

Proximal Tube

Front

In the vertebrate kidney, the portion of the nephron immediately downstream Bowman's capsule that conveys and helps refine filtrate

Back

Urethra

Front

A tubethat releases urine from the mammalian body near the vagina in females and through the penis in males; also serves in males as the exit tube for the reproductive system

Back

Vasopressin (ADH)

Front

Produced by the hypothalmus and stored in the posterior pituitary gland; Increases blood volume, cardiac output, and arterial pressure

Back

Renal Vein

Front

The blood vessel that carries blood away from the kidney

Back

Glomerulus

Front

A ball of capillaries surrounded by Bowman's capsule in the nephron and serving as the site of filtration in the vertebrate kidney

Back

Angiotensin

Front

Causes vasoconstriction and an increase in blood pressure

Back

Loop of Henle

Front

The hairpin turn, with a descending and ascending limb, between the proximal and distal tubules of the vertebrate kidney; functions in water and salt reabsorption

Back
