Question 6

Origin of lactic acid and organ of excretion

Answer 6

Product of anaerobic respiration and excreted through the liver

Question 7

Origin of solid waste and organ of excretion

Answer 7

Question 8

What is a Contractile Vacuole

Answer 8

Structure in unicellular organisms that maintains osmotic equilibrium by pumping fluid out from the cell

Question 9

What are ureters

Answer 9

Tubes that conduct urine from kidneys to the bladder

Question 10

What is the urethra

Answer 10

Tube that carries urine from the bladder to the exterior of the body

Question 11

What is the cortex

Answer 11

Outer layer of the kidney

Question 12

What is the medulla

Answer 12

Area inside of the cortex

Question 13

Renal pelvis

Answer 13

Area where the kidney joins the ureter

Question 14

What are nephrons

Answer 14

Functional units of the kidney

Question 15

Afferent arterioles

Answer 15

Small branches that carry blood to the glomerulus

Question 16

Glomerulus

Answer 16

High-pressure capillary bed that is the site of filtration

Question 17

Efferent arterioles

Answer 17

Small branches that carry blood away from the glomerulus to a capillary net

Question 18

Peri tubular capillaries

Answer 18

Network of small blood vessels that surround the nephron

Question 19

Bowman’s capsule

Answer 19

Cup like structure that surrounds the glomerulus

Question 20

Proximal tubule

Answer 20

Section of nephron joining the Bowman’s capsule with the loop of Henle

Question 21

Loop of Henle

Answer 21

Carries filtrate from the proximal tubule to distal tubule

Question 22

Distal tubule

Answer 22

Conducts urine from the loop of Henle to the collecting duct

Question 23

Collecting duct

Answer 23

Tube that carries urine from nephrons to the pelvis of a kidney

Question 24

What are 3 solutes that can’t enter Bowman’s capsule

Answer 24

1. Plasma Proteins
2. Erythrocytes (blood cells)
3. Platelets

Question 25

What is filtration

Answer 25

Process where blood or body fluids pass through a selectively permeable membrane

Question 26

What is reabsorption

Answer 26

Transfer of glomerular filtrate from the nephron back into capillaries

Question 27

What is secretion

Answer 27

Movement of materials, such as ammonia and some drugs, from the blood back into the distal tubule

Question 28

What is Interstitial Fluid

Answer 28

Fluid that surrounds the body cells

Question 29

What is Antidiuretic Hormone (ADH)

Answer 29

Causes kidneys to increase water reabsorption

Question 30

What are Osmoreceptors

Answer 30

Specialized nerve cells in the hypothalamus that detects changes in the osmotic pressure of the blood and surrounding extra cellular fluids (ECF)

Question 31

What is Aldosterone

Answer 31

A hormone that increases Na+ reabsorption from the distal tubule and collecting duct
