Anatomy Questions

- Merging of ascenidng lumbar and subcostal veins on left side of the body- Hemiazygos vein ascends through the thorax, it drains the left posterior intercostal veins 11-8.- Drains into the azygos vein.- This venous junction connects drainage of the lower and upper torso regions.

Superior and inferior epigastric arteriesExtend vertically along the abdominal wall

The internal thoracic artery (aka, mammary artery) is a preferred artery in coronary artery bypass grafts because it is relatively resistant to atherosclerosis, and thus is more durable.

The lack of valves of the venous plexuses facilitates spread of malignant cells (e.g., from prostate cancer) and bacteria in the bloodstream to the vertebrae, leading to metastases and osteomyelitis.

Subcostal artery- Arises from the abdominal aorta below the 12th rib, and,Ascending branch of the deep circumflex artery- Arises in the hip

Drains into the brachiocephalic vein; it receives the musculophrenic vein and anterior intercostal veins

Drain into the common iliac veins; they ascend along the lumbar vertebrae

Receives venous drainage from the 11th to 4th right posterior intercostal veins.

Drains into the arch of the azygos vein; the right superior intercostal vein is the final tributary of the azygos vein before it drains into the superior vena cava

- Descends along the superior posterior thoracic wall on the left side of the body and typically drains into the azygos vein.- Drains the 7th-4th posterior intercostal veins on the left side of the body.

The ascending lumbar veins provide a vital alternative pathway for venous return if the inferior vena cava becomes blocked.The azygos system also provides collateral venous drainage pathways in the case of obstruction of the superior vena cava.

- There are 12 ribs and 11 intercostal spaces, which lie between the ribs ("costal" means rib).- Intercostal space numbering begins with the space between ribs 1 and 2.- The space inferior to rib 12 is called the "subcostal" space, since it is below ("sub") the rib.- The thoracic walls are primarily supplied by intercostal arteries, which travel within the intercostal spaces between the ribs.

Drains into the common iliac vein; it receives the 5th lumbar vein.

Merge to form the inferior vena cava, which ascends through the thorax.

- Drains into the ascending lumbar vein.- Subcostal and ascending lumbar veins form the azygos vein, which drains directly into the superior vena cava, which also drains the brachiocephalic veins

Tiny air sace at the end of the bronchioli in the lung which enable the gaseous exchange (O2 <-> CO2)

1. Keeps the baby warm2. Keeps the baby's rapidly growing body parts from fusing together.3.Lets the baby move easily which develops muscle and strengthens joints and bones.4.Provides cushioning for the baby and protects from physical harm.5.It is made up of 98% water and 2% salts and cells from the baby.Until the month 4, the mother makes the amniotic fluid. When the foetal kidneys start to work, the foetus releases water and salts and all other liquids.

A ring of muscle, closing the lower end of the uterus, where it joins the vagina.
