Flashcards in CH 10 Urinary System, Metabolism and Body Fluids Balance Deck (35):
0

A complete obstruction of urinary flow sometimes caused by enlargement of the prostate gland

Acute Urinary Retention

1

One of two components of metabolism. Building or "Constructive Phase" in which smaller molecules are converted to larger molecules

Anabolism

2

A hormone released by the pituitary gland that causes the kidneys to reabsorb more water into the blood and excrete less urine.
When body fluid levels become decreased, the sensation of thirst stimulates an individual to take more fluids in.Increased body fluid levels, on the other hand, suppress thirst and increase excretion of fluid by the kidneys as urine.
Another way is moving water throughout the body
Lack of (ADH) results in very dilute urine.

Antidiuretic hormone (ADH)

3

The baseline metabolic rate of the body, or energy required to maintain the body's normal functions while at rest

Basal Metabolic Rate (BMR)

4

A thin, double-walled chamber that surrounds the glomerulus

Bowman's Capsule

5

Large urinary tubes that enter the renal pelvis from kidney tissue

Calyces

6

The "Destructive Component" of metabolism associated with the breakdown of large molecules into smaller molecules

Catabolism

7

A biochemical process resulting in the production of energy in the form of ATP. Takes place in the Mitochondria

Cellular Respiration

8

A bacterial infection of the bladder and it's urinary contents

Cystitis

9

A condition often caused by pituitary dysfunction that is associated with production of large volumes of diluted urine and which patients experience intense thirst

Diabetes Insipidus

10

A procedure in which an artificial kidney external to the body is used to purify the blood

Dialysis

11

The process of maintaining homeostasis through equal intake and out put of fluids.

Fluid Balance

12

The rate at which blood is filtered through the glomerula

Glomerular Filtration Rate

13

A semipermeable capillary filter located within Bowman's capsule in the nephron

Glomerulus

14

Storage from for glucose in the liver

Glycogen

15

The part of the brain respnsible for maintenance of homeostasis including control of body temperature, fluid and electrolyte balance and blood pressure. It produces antidiuretic hormone (ADH)

Hypothalamus

16

A spinal reflex that cause contraction of smooth muscle of the bladder, allowing for urination

Micturition Reflex

17

The function unit of the kidney. Urine is formed here

Nephron

18

A potentially severe bacterial infection of the renal pelvis, medulla, and cortex

pyelonephritis

19

A protective layer of fibrous connective tissue surrounding each kidney

Renal Capsule

20

A hormone produced by cells in the juxtaglomerular apparatus when the blood pressure is low

renin

21

A pair of thick-walled, hollow tubes that carry urine from the kidneys to the urinary bladder

Ureters

22

A hollow, tubular structure that drains urine from the bladder, passing it outside of the body

Urethra

23

The body's sources of "fuel" or energy

Glucose is the major fuel source but fats, and proteins also help give energy to the body

24

The final products of carbohydrate digestion in the gut are

Glucose, Fructose, and Galactose

25

Heat loss from the body takes in 4 ways

Radiation- heat is transmitted through space, heater or fireplace
Conduction- transmission of heat from warmer to cooler object by direct contact
Evaporation- heat at the surface is lost because of vaporization of liquid
Convection- Transfer of heat by circulation of heat particles

26

One of two types of body fluids. Fluid outside of cells

Extracellular Fluid

27

One of two types of body fluids. Fluid inside cells

Intravascular Fluid ( Plasma)

28

Protective layer of fibrous connective tissue, surrounding each kidney

Renal Capsule

29

Filtration of blood to remove waste products, excreting them as urine, the maintenance of fluid and electrolyte balance. Structures within this system are; nureters, kidneys, urinary bladder and urethra

Urinary System

30

solid, bean-shaped organs located in the retroperitoneal space behind the abdominal and pelvic cavities. Filter blood, removes wastes and excrete waste as urine

Kidneys

31

Major Mechanisms for fluid homeostasis

Antidiuretic Hormone (ADH)
Thirst
Kidneys
Water Shifts

32

Increased blood pressure

Capillary blood pressure affects a change in volume by increasing filtration and urine output

33

Decreased Blood pressure

increased water retention

34

Female urethra

4 inches long, easily infected ( UTI). Fused with the anterior wall
