1

What is the largest gland in the body?

Liver

2

T/F
The liver is the third largest single organ.

F
The liver is the SECOND largest single organ (next to the skin).

3

The liver is ___ % of an adult's body weight, ___ % of the total fetal weight.

2.5 %, 5 %

4

During fetal development, what is the function of the liver?

It is a hematopoetic organ.

5

The liver can be found in which quadrant and region of the body?

RUQ of the abdomen;
R Hypochondrium, Epigastric, and L Hypochondrium

6

T/F
The liver is enclosed by peritoneum.

F
The liver is surrounded by peritoneum except on the BARE AREA of the liver.

7

Where can one find the bare area of the liver?

Posterosuperior aspect of the liver;
Closely related to the diaphragm

8

What is the tight fibrous capsule that encloses the liver?

Glisson's Capsule

9

What is the location of the liver with respect to the ribs and surface anatomy?

It is deep to the 7th-11th ribs and crosses the midline towards the left nipple.

10

What structures protect the liver?

Anteriorly: Lower rib cage
Posteriorly: muscles and bones of the abdominal cavity

11

Identify the functions of the liver.

(1) Glycogen storage
(2) Bile secretion
(3) other metabolic actities

12

T/F
All nutrients (except fat) absorbed from the digestive tract are initially conveyed to the liver by the portal venous system.

T

13

Path of Bile (from liver)

Liver (via biliary ducts/ R and L hepatic ducts) -> Common Hepatic Duct -> (+ cystic duct) -> Common Bile Duct

14

What are the five ligaments of the liver?

(1) Falciform Ligament
(2) Coronary Ligament
(3) R Triangular Ligament
(4) L Triangular Ligament
(5) Round Ligament

15

The falciform can be divided into:

R and L leaflet

16

Location of the falciform

from the umbilical notch on the inferior surface of the liver portal hepatis

17

Function of the falciform ligament:

(1) subdivided the subphrenic spac

18

T/F
The R leaflet becomes the R triangular ligament while the L leaflet becomes the coronary ligament

The R leaflet becomes the coronary, while the L leaflet becomes the L triangular ligament.

19

Function of the Right Triangular Ligament

It attaches the liver to the undersurface of the right leaflet of the diaphragm.

20

Location of the round ligament

found at the base of the falciform from the umbilicus

21

The round ligament is continuous with what structure?

Ligamentum Venosum

22

Embryonic Function of the ligamentum venosum

fibrous remnant of the fetal ducts venosus;
Shunts blood from the umbilical vein to the IVC

23

Enumerate the "H" Fissures of the liver

Right Limb:
Anterior Right - Fossa for the Gall Bladder
Posterior Right - Groove for the IVC

Left Limb:
Anterior Left - fissure for ligamentum teres
Posterior Left - fissure for ligamentum venosum

Crossbar of "H": Porta Hepatis, which contains:
Common Hepatic Duct
Hepatic Artery
Hepatic Portal Vein
Hepatic Nerve Plexus
Lymphatic vessels

24

What is the significance of the "H" fissure?

It divides the liver into four lobes (R, L, caudal, quadrate).

25

T/F
The liver is divided into four anatomical lobes.

F
The liver is divided into two anatomical lobes and two accessory lobes.

26

T/F
The R and L lobes do not communicate.

T
Each lobe has own arterial supply, venous drainage, and biliary drainage.

27

T/F
The caudate lobe is not located in the caudal position.

T
The caudate lobe is not positioned caudally. It is named as such because of the "tail" or the ELONGATED PAPILLARY PROCESS.

28

What is the function of the elongated papillary process?

It connects the caudate and right lobes of the liver.

29

T/F
The right and left livers are functionally dependent with one another.

F
The two lobes of the liver are functionally independent.

30

What are the vessels that supply and drain the liver? What drains the liver contents?

Hepatic artery and Hepatic Portal Vein
Hepatic Duct
