Answer 7

Acini cells

Question 8

Function of the parotid gland

Answer 8

Secrete serous that contains enzymes e.g. amylase

digest food and lubricates for swallowing

Question 9

Striated ducts

simple columnar epithelium

Question 10

Submandibular glands secrete

Answer 10

serous and mucous

Question 11

Slavery can secretion is affected by neuronal stimulus is explain how is affected

Answer 11

Parasympathetic: produces a large volume of watery saliva rich in enzymes
sympathetic: produces a small thick secretion of saliva re-rich in mucus

Question 12

The liver exocrine secretion

Answer 12

Constitutive: secretes bile

Question 13

The liver endocrine secretion

Answer 13

Constitutive: albumin
regulated: IGF- 1

Question 14

Hepatic blood supply- what is a portal system

Answer 14

Two capillary systems between hearts arterial supply and the hearts of venal supply

Question 15

Where are the two areas the hepatic portal system capillaries branch

Answer 15

Stomach and intestine- nutrients and toxins absorbed

liver- nutrient and toxins leave

Question 16

Where does the deoxygenated blood from the liver come from

Answer 16

Other organs such as stomach which is a portal system, so will first capillary branch at the stomach, then travel via the portal vein to the liver where they will secondary branch

Question 17

At the end of the hepatic triad blood collects into the central canal, where does the blood go then

Answer 17

Central canal to hepatic vein to vena cava

Question 18

Hepatic triad come together at the end of hepatic lobules also known as

Answer 18

acini

Question 19

Name the three components of the hepatic triad

Answer 19

Bile duct
portal vein
hepatic artery

Question 20

Describe the basement membrane in the sinusoid

Answer 20

Incomplete basement membrane, intracellular gaps

Question 21

Describe the structure of the liver lobule

Answer 21

Liver lobule hexagonal shape - six sides
central vein
hepatocyte do not form straight lines

Question 22

Describe the directions which the sinusoids and the bile duct moves fluids

Answer 22

Sinusoids needs fluid towards the central canal

Bartok meets fluids away from central canal

Question 23

Where are kupffer cells found

Answer 23

Sinusoids lumen

Question 24

What is the space of disse

Answer 24

Space between sinusoid and hepatocyte

Question 25

Which surfers due hepatic cells have microvilli on

Answer 25

These basoateral surface Note hepatic cells have reversed apical and basal surface

Question 26

What is the tube called which transports bile to the bile duct

Answer 26

bile canaliculus

Question 27

Where do the bile canaliculus run in respect to hepatocytes

Answer 27

Above or below never through

Question 28

Kupffer cells

Answer 28

Specialist macrophage | the trap and phagocytosis any damage or age you refer sites that were missed by the spleen

Question 29

When the spleen is remove what role can the liver play and what cells and others to happen

Answer 29

kupffer cells intake over the removal of the hundred and 20 day old you refer sites

Question 30

What roles do stellate cells play in liver fibrosis

Answer 30

Hepatic stellate cells lose their vitamin a storage ability and differentiate into Myofibroblasts. These synthesise and deposit collagen leading to liver fibrosis

Question 31

Four functions of the liver

Answer 31

Storage anabolism- production catabolism- destruction other functions

Question 32

Answer 32

Iron vitamin a B12 D and K (lipid soluble vitamins) glycogen copper

Question 33

Anabolism role of the liver

Answer 33

Makes more than 60% of bodies proteins major plasma protein- albumin enzymes haemopoeisis in the foetus from week 5 to 32

Question 34

Catabolism role of the liver

Answer 34

Drugs hormones toxins After spleen removed can remove red blood cells

Question 35

Give the exocrine and endocrine function of the liver

Answer 35

Bile production exocrine endocrine constitutive- albumin regulated IGF-1

Question 36

How do you have pattern sites differ to other cells

Answer 36

Numerous mitochondria lots of paroxisomes - organelles full of oxidising agents numerous free ribosomes a lot of rough endoplasmic reticulum and smooth endoplasmic reticulum numerous golgi complexes glycogen deposits
