Hepar
seize: largest gland in body
color: dark reddish-brown
weight: 1,5 kg
hepar - functions
1. digestive function
- acts as exocrine gland in respect of production of bile
2. barrier function
3. phagocytic function
4. thermoregulation
5. involved in carbohydrate, protein and fat metabolism
6. in fetal period of life it produces erythrocytes
production of bile
how often: uninterruptedly
excretion:
- through ductus hepaticus dexter et sinister
- pass through porta hepartis
- joing to form ductus hepaticus communis
ductus hepaticus communis
- location: in lig. hepatoduodenale
hepar - outer description
- 2 surfaces
- 2 margins
- 3 grooves
hepar - surfaces
1. facies diaphragmatica
2. facies visceralis
hepar - facies diaphragmatica
--> superior surface
shape: convex
projected: toward diaphragm
lig. falciforme
- separates lobus dexter et lobus sinister
lobus dexter
--> much larger than lobus sinisterv
hepar - facies visceralis
projected: downward
- towards abdominal organs
hepar - margins
1. margo inferior
2. margo posterior
hepar - margo inferior
shape: thin + sharp
projected: downward
- opposite to attachement of lig. falciforme: marked by deep notch
hepar - margo posterior
shape: round
area nuda
- not covered by peritoneum
hepar - grooves
--> on visceral surface
1. right sagittal groove
2. left sagittal groove
3. transverse groove with porta hepatis
right sagittal groove
separates:
- lobus dexter
- rest of lobes
anteriorly: vesica biliaris (fellea) --> fossa vesicae biliaris
posteriorly: sulcus v. cavae with v. cava inferior
left sagittal groove
separates:
- lobus sinister
- rest of lobes
anteriorly: fissura lig. teretis with lig. teres hepatis
- before birth: lig. teres hepatis = v. umbilicalis
posteriorly: fissura lig. venosi with lig. venosum
- before birth: lig. venosum = ductus venosus
transverse groove
between:
- left sagittal groove
- right sagittal groove
separates:
- anteriorly: lobus quadratus
- posteriorly: lobus caudatus
porta hepatis
