Describe the structure of the plasma membrane:

Well, the plasma memebrane is made of a phospholipid bilayer, two layers of acids, which are called hydrophillic,head and a hydrophobic tail. The heads point outward; the tails point inward.The plasma membrane is semi-permeable, allowing small polar molecules through. Larger molecules, however, such as glucose, cannot pass through the membrane through diffusion.

Describe the function of the plasma membrane:

The plasma membrane surrounds the outside of theEukaryotic and Prokaryotic cells. It is made up of a double layer of phospholipids and controls the movement of various substances into and out of the cell, both passively and actively.

Explain how the plasma membranes structure helps it carry out its function:

Like all other cellular membranes, the plasma membrane consists of both lipids and proteins. The fundamental structure of the membrane is the phospholipid bilayer.which forms a stable barrier between two aqueous compartments. In the case of the plasma membrane. these compartments are the inside and the outside of the cell. Proteins embedded within the phospholipid bilayer carry out the specific functions of the plasma membrane including selective transport of molecules and cell-cell recognition.

The Urinary System

The urinary system is important to the human body. This system helps to regulate blood pressure and also by removing waste products from the blood. The first step in this process is when the blood enters through the renal artery, after that it enters the glomeruluos. This forces the blood in to the filtrate, this is also known as filtration.

Then it enters the nephrons which wastes are filtrated out from. Reabsorption plays the role of returning useful molecules back into the blood. Then it travels to the collecting duct. And lastly it is moved through the urethra. And the urine is removed.
