Excretory

Question 1

What is excretion?

Answer 1

removal of waste through lungs,skin, and kidneys

Question 2

Lungs function

Answer 2

Exhale CO2 via cell respiration

Question 3

Sweat glands function

Answer 3

Sweat and release H2O, Urea, and salt (in sweat)

Question 4

Kidneys function

Answer 4

filters and cleans the blood to produce the waste known as urine.

Question 5

What is urine high in?

Answer 5

Urea. It also contains some salt and water

Question 6

3 of the functions of kidneys to maintain homeostasis :

Answer 6

1. Regulate the volume, composition, and pH of body fluids
2. Remove metabolic waste from the blood and eliminate them
3. Regulate blood pressure and calcium ion absorption

Question 7

Reabsorption

Answer 7

When the nutrients are filtered and sent back from the kidneys via renal vein to the inferior vena cava

Question 8

Glomerulus

Answer 8

Bunch of capillaries that act as a filter letting small materials go in the nephron

Question 9

Nephron

Answer 9

Composed of capillaries and tubules, it is where the waste is after all the filtering and goes to the duct to be released as urine

Question 10

Excretion in kidney

Answer 10

Urine passes to collecting ducts in the nephron until it passes out of the kidney

Question 11

Ureter

Answer 11

thin tubes that transport urine to the bladder

Question 12

Bladder

Answer 12

smooth muscle that stores urine until excretion

Question 13

Urethra

Answer 13

tubes that transports urine out of the body

Question 14

Dialysis machine

Answer 14

Filters blood, used if ones kidneys don’t filter enough

Question 15

Renal Vein

Answer 15

Send the filtered blood to the inferior vena cava of he heart

Question 16

Renal Artery

Answer 16

Sends the blood that is not filtered to the kidney

Question 17

What happens if the Renal Artery is blocked?

Answer 17

It can lead to kidney failure or hypertension (high blood pressure)

Question 18

Bowman’s Capsule

Answer 18

Filters the blood from the glomelur capilaries

Question 19

Loop of Henle

Answer 19

A spiral loop that filters and reabsorbs the nutrients, by capillaries on the loop

Question 20

Proximal convoluted tubule

Answer 20

The tube closest to Bowman’s Capsule and links it to the loop of henle

Question 21

Distal convoluted tubule

Answer 21

The tube farthest away from bowman’s capsule and links the loop of henle to the collecting duct

Question 22

collecting duct

Answer 22

Takes the urine from the nephron and sends it to the renal pelvis and ureters

Question 23

How does the blood from the renal artery enter Bowman’s capsule

Answer 23

Enters through glomerulus and into by diffusion

Question 24

How to detect diabetes?

Answer 24

1.Sugar in Urine
2.Really thirsty
3.Fatigue
4.Sick

Question 25

Type 1 diabetes

Answer 25

No insulin , allows sugar into cells

Question 26

Parts of the nephron (8 parts)

Answer 26

-Bowman’s capsule
-Renal Artery (high in waste)
-Renal Vein (Clean blood)
-Glomerulus
-Proximal convoluted tubule
-Distal convoluted tubule
-loop of henle
-collecting tubule
