Excretion

Question 1

Big Great People Love Doing Cool Things

Name the parts of the Nephron

Answer 1

Bowman’s Capsule
Glomerulus
Proximal convoluted tubule
Loop of Henle
Distal convoluted tubule
Collecting dust

Question 2

What is the Bowman’s capsule do?

Answer 2

Site of pressure filtration

Question 3

Excretion

Answer 3

Exccretion is the proccess removing metabolic waste from the body

Question 4

Glomerulus

Answer 4

Ball of capillaries where filtration of blood occurs

Question 5

Proximal convoluted tubule

Answer 5

Reabsorption of glucose, amino acids, water, and salt happens

Question 6

Loop of Henle

Answer 6

Maintains a salt gradient; reabsorbs water and salts

Question 7

Distal convoluted tubule

Answer 7

Further salt/water balance; but responding to hormones.

Question 8

Collecting duct

Answer 8

Final water reabsorption; responds to ADH.

Question 9

What is Pressure Filtration?

Answer 9

High blood pressure forces small molecules (water, glucose, salts, urea) out of the blood into the Bowman’s capsule from glomerulus.

Question 10

Why is Pressure Filtration important?

Answer 10

Begins urine formation by filtering waste from the blood

Question 11

How does Kidney Failure refer to Excretion?

Answer 11

In kidney failure, waste like urea and excess water build up in the blood. Leads to toxicity, swelling, high blood pressure, and potentially death.

Question 12

Glucose in the blood

Answer 12

Normally reabsorbed in the PCT of the nephron → should not appear in urine. If it does, could indicate diabetes.

Question 13

CO2 in the blood

Answer 13

• Waste from respiration then gets dissolved in blood and removed by lungs during exhalation.

Question 14

Source and Organ of Urea

Answer 14

Urea is made in the liver from the breakdown of proteins and is removes by the kidneys through urine

Question 15

Source and Organ of CO2

Answer 15

CO2 is made in cells during respiration and is removed by lungs through exhalation

Question 16

Source and Organ for sweat

Answer 16

Produced by sweat glands for releasing heat/ temp control and it is released through skin

Question 17

Cool Monkeys Prefer Using Really Fast Elevator

Parts of the Kidney

Answer 17

Cortex
Medulla
Pelvis
Ureter
Renal artery
Renal vein

Question 18

FILTERS REMOVES EVERYTHING FROM ERICA BUT YOU

Role of ADH (Antidiuretic Hormone)

Answer 18

Produced by the hypothalmus and released by pituary gland
It Increases permeability of collecting duct to water.

Question 19

When water is low what happens?

Answer 19

ADH increases → more water reabsorbed → concentrated urine
