| What is the primary function of the lymphatic system? | show 🗑
|
||||
| Describe the origin of interstitial fluid and lymph | show 🗑
|
||||
| show | afferent, efferent
🗑
|
||||
| show | Internal jugular, subclavian, right lymphatic, thoracic
🗑
|
||||
| show | right lymphatic; thoracic
🗑
|
||||
| * Describe the path and location of the thoracic duct | show 🗑
|
||||
| show | At the junction of the right internal jugular and the right subclavian veins
🗑
|
||||
| show | Axillary nodes
🗑
|
||||
| show | Inguinal nodes
🗑
|
||||
| The lymphatic vessels from the wall of the thorax and abdomen for the most part drain into the ____ and ____ nodes. Some vessels pierce the body wall to run to deeper nodes, particularly in the anterior wall of the _____. | show 🗑
|
||||
| Where is the watershed between the inguinal and axillary drainage areas? | show 🗑
|
||||
| What are the main vessels carrying lymph from the axilla? Where do they pass? | show 🗑
|
||||
| Where do the efferent vessels from the inguinal nodes pass through? Where do they drain? | show 🗑
|
||||
| Where are the superficial inguinal nodes located? Where do they receive lymph from? | show 🗑
|
||||
| show | Receive ALL the lymph from the superficial nodes and from the deep structures of lower limb; efferent vessels ascend via femoral canal and drain into external iliac nodes.
🗑
|
||||
| show | Alongside carotid sheath; known as deep cervical nodes; jugular trunk; drain skin and superficial fascia AND deeper structures

| show | bronchomediastinal
🗑

| Which trunks join the right lymphatic duct? | show 🗑
|
||||
| show | Along blood vessels; groups include pre-aortic and para-aortic nodes
🗑
|
||||
| show | Along front of aorta in 3 groups: celiac nodes (foregut), superior mesenteric nodes (midgut), inferior mesenteric nodes (hindgut); intestinal trunk (contributes to cysterna chili)
🗑
|
||||
| How are the para-aortic nodes arranged? Where are they? What do they drain? What the efferents from these nodes form? | show 🗑
|
||||
| show | Internal iliac nodes (organs supplied by internal iliac arteries EXCEPT gonads, uterine tube, fundus, upper body of uterus, which drain into para-aortic/lumbar nodes); external iliac nodes-->common iliac nodes-->lumbar nodes

|
||||
| show | Lie in apex of axilla at lateral border of first rib; receive efferents from other axillary nodes; efferents from apical group form the subclavian lymph trunk
🗑
|
||||
| Describe Drainage of breast: what node groups drain most of it? | show 🗑
|
||||
| show | Few to superficial inguinal nodes, most unite with lymphatics from uterine tube and ovary passing to lumbar (para-aortic) nodes; internal, external, and common iliac nodes, sacral nodes
🗑
|
||||
| show | Upper 3/4s: internal iliac nodes; lower 1/4: superficial inguinal nodes; para-aortic (lumbar) nodes
🗑
