Week 12

Question 1

Kidney has three main jobs

Answer 1

Filters blood
Reabsorbs and secrete ions
Produce urine

Question 2

The main function of urinary system

Answer 2

To make urine
Controls the body’s fluid and electrolyte balance
eliminates waste products

Question 3

The urinary system consists of

Answer 3

2 kidneys
2 Ureter
Urinary bladder
The urethra

Question 4

Glomerular filtration

Answer 4

Blood from the renal artery is filtered in the glomerulus. The filtered product which contains water, salts, nutrients, waste products is called glomerular filtrate

Question 5

Tubular Reabsorption

Answer 5

Substances stay in the body after being removed from urine

Question 6

Tubular secretion

Answer 6

Substances move from the blood stream and are eliminated from the body in the urine

Question 7

Renal capsule

Answer 7

The kidneys are covered by a fibrous layer of connective tissue

Question 8

Renal hilum

Answer 8

The indentation that gives the kidney it’s bean shape

Question 9

Renal arteries

Answer 9

Bring blood to the kidneys to be filtered

Question 10

Renal veins

Answer 10

Take the filtered blood away from the kidney to go back to the heart

Question 11

Kidney

Answer 11

Bean-shaped organ located in the superior dorsal abdominal cavity that filter blood to make urine

Question 12

Ureter

Answer 12

A tube that Carrie’s urine from each kidney to the urinary bladder

Question 13

Urinary bladder

Answer 13

Is basically an expandable sac that holds urine

Question 14

Urethra

Answer 14

Is a tube that transports urine from the bladder to the outside of the body

Question 15

Renal

Answer 15

Kidney

Question 16

Renal cortex

Answer 16

Outer layer
This is where blood filtration occurs

Question 17

Renal medulla

Answer 17

Middle layer
Composed of collecting tubules for the urine that I’d formed in the kidney

Question 18

Renal pelvis

Answer 18

Inner later
A funnel, divided into 2 or 3 large collecting cups called major calyces

Question 19

Pathway

Answer 19

The blood is filtered
Filtrate through tiny tubules in the medulla and collects in the renal pelvis
The renal pelvis empties into the ureter where the filtered urine is carried to the bladder

Question 20

Afferent arteriole

Answer 20

Leads to a ball of capillaries called glomerulus

Question 21

Efferent arterioles

Answer 21

Leave from the glomerulus

Question 22

Peritubular capillaries and collecting tubules

Answer 22

Specialized series of capillaries
Part of the renal nephron
Wrapped around the tube

Question 23

Bowman capsule

Answer 23

Surrounds the glamerulus
Part of the nephron

Question 24

The nephron

Answer 24

Functional unit of the kidney
Can be divided into two part
Renal corpuscle
Renal tubule

Question 25

Renal corpuscle

Answer 25

The first part which is filtered Double filter

Question 26

Renal tubule

Answer 26

Where reabsorption and secretion take place

Question 27

Glomerular filter

Answer 27

Material filtered from the blood unto the glomerular capsule Location

Question 28

Nephron lobe or Loop of henle

Answer 28

From the proximal tubule, glomerular filtrate flows into Consists of descending loop of henle and ascending loop of henle

Question 29

Filtration

Answer 29

Pass through glomerular capillaries into the glomerular capsule Moves into nephron from blood Filtrate flows into the renal tubules

Question 30

Peritublar

Answer 30

Tiny blood vessels in the capillaries

Question 31

Reabsorbed

Answer 31

went through the filter and into the glomerular capsule can be reabsorbed into peritubular capillaries

Question 32

Secretion

Answer 32

Is when substances move from the capillaries into the renal tubule and leave in the urine

Question 33

Permeability

Answer 33

Is how easy it is for substances (such as glucose) to pass through the wall

Question 34

Kidneys role in homeostasis

Answer 34

Maintain electrolyte balance Acid/base relationship Hormones assist

Question 35

Major calyx and minor calyx

Answer 35

Filtrate flows out of the collecting duct into the minor calyces and then into the major calyces

Question 36

Urination reflex

Answer 36

Bladder fills, this stretch triggers urinary reflex, signal sent to brain. Brain sends signals back to contract for bladder to empty

Question 37

Urinary tract infections

Answer 37

Is caused by the movement of fecal bacteria into the urinary tract

Question 38

Permeability

Answer 38

The state or quality of a material or membrane that cause it to allow liquid or gasses to pass through it

Question 39

Osmosis

Answer 39

Equalizing the concentration of both sides of the material

Question 40

Diffusion

Answer 40

Spreading of something more widely

Question 41

Answer 41
