Hi!
The structure of a plasma membrane will consist of both proteins as well as lipids. This membrane is considered a boundary which will separate the living cell away from their non-living surroundings.
Then the common characteristics of this membrane could be that it is made up of two layers of phospholipids and that it has a wide variety of proteins embedded in it.
Hope I helped!

As the left ventricle contracts, oxygenated blood leaves the heart through the aortic valve, into the aorta. The blood to lower limb flows through descending aorta, which continues down to Left Common Femoral Artery, which continues down to Left Superficial Femoral Artery, which continues down to Left Popliteal Artery. The Left Popliteal Artery gives 2 divisions.
1. Left Tibioperoneal Artery (which continues down to the Left Posterior Tibial Artery which supplies back of the foot.)
2. Left Anterior Tibial Artery (which continues down to Left Dorsalis Pedis Artery which continues down to <em>Left First Dorsal Metatarsal Artery</em> which supplies the big toe/first digit of foot.)
