Where does the waste material in the body come from and why does the body need to get rid of these waste materials?
Marizza181 [45]
"Waste" -- in the form of urine and feces -- how the body removes the parts of food we ingest that is not used for nutrition and also is a way to rid the body of toxins. The kidneys filter the blood, removing "waste" products such as excess vitamins or drugs (this is why your urine can have a bright color if you take high doses of vitamin c) and liquid waste is held in the bladder before being released. Food travels through the gut to be digested -- broken down into usable bits and waste. After breaking down in the stomach, the material travels through the small and large intestines. The small intestine is lined with villi -- tiny protrusions that add surface area so nutrients can be absorbed into the bloodstream. In the large intestine and colon, water is pulled from the mass so it becomes more solid. Eventually the solidified waste passed through the rectum and out the anus as feces. The build-up of waste in the body can itself be toxic -- if the kidneys do not function properly to clean the waste out, the buildup can be fatal. When the body goes into emergency mode to eliminate a toxic substance -- such as e. Coli in the case of food poisoning -- the intestines don't both absorbing water and the result is the liquid fecal matter being quickly passed through and ejected as diarrhea.

Why is the resting membrane potential (Vm) approximately - 70 mV for most cells? Most cells contain a large concentration of Cl-
Yuki888 [10]

Answer:

Option (4).

Explanation:

Cell membrane potential may be defined as the difference in the electric potential between inside and outside of the cell. This potential is important for the action potential.

The resting membrane potential of the cell is -70mV. This membrane potential is maintained by the potassium ions of the cell. The cell membrane are almost 40 times more permeable to potassium ions than sodium ions and makes the cell membrane potential negative.

Thus, the correct answer is option (4).

deff fn [24]

Answer:

A

Explanation:

The pulmonary artery carries de-oxygenated blood from the right ventricle of the heart to the lungs. It is the only artery that carries de-oxygenated blood. This blood is usually from the tissues and has a lot of carbon dioxide from the cellular respiration of cells around the body. The blood is pumped to the lungs to be oxygenated and the carbon dioxide expelled.
