The blood in the Renal Vein:
* Is low in oxygen. * Returns to the heart. The blood in the Renal Artery:
* Has high amounts of oxygen. * Is pumped from the heart.
I would have thought it would be the renal vein due to veins carrying blood at low pressure. Valves prevent the backflow of blood. I would be surprised if the renal artery contains any valves at all
renal vein has a . larger lumen . smaller elastic layer . smaller muscular layer than the renal artery
the livers.
The renal artery supplies blood to the renal system, or the kidneys. The renal artery differ with the renal vein in containing the less concentration of co2 and more concentration of urea
Aorta..has to pump blood to the entire body. Pulmonary artery has to pump to the lungs...much less of a distance.
YES! veins are more compliant than arteries. it means they are more capable of adopting their lumen size with changes in blood volume inside their lumen .when blood volume increase inside a vein lumen it easily expands and accepts whatever amount of blood reach and when blood volume decreases squeezes and adopt its lumen size for that amount of blood . but when we are talking just about arteries and want to compare one artery to another artery ,we should know that aorta is most compliant artery,remember the farther away from heart the less elastin in artery wall hence less compliance.
Arteries carry blood, oxygenated by the lungs, to the cells of the body. Since the heart is a large muscle, its cells need oxygen too. When one of the arteries supplying the heart with oxygenated blood is blocked ("occluded") the oxygen cannot reach the cells supplied by that artery.
Arteries are more elastic but have smaller lumen. They carry blood away from the heart. Veins are less elastic have larger lumen and have valves. They carry blood to the heart.
Renal vein.
The renal artery supplies blood to the renal system, or the kidneys. The renal artery differ with the renal vein in containing the less concentration of co2 and more concentration of urea
Urea
Ammonia is less soluble than uric acid.
the kidney is referred to as an excretory organ and excretes urea, which is a less toxic form of uric acid.
Urea is the less toxic in nature among the nitrogenous wastes where as Ammonia is 100,000 times toxic than urea.
Most fish excrete nitrogenous waste in the form of ammonia. Ammonia is highly toxic, but fish eliminate it primarily through the gills and some through the urine. Some fish species, particularly those living in environments with low water availability, convert ammonia to a less toxic form, such as urea or uric acid, before excreting it.
Ammonia has only one nitrogen per molecule, but it is quite toxic. It requires a great deal of water to be flushed out of the body. Reptiles including birds go one step further, packaging their nitrogenous waste as uric acid. That white stuff you see from a bird or a snake it has less water in the poop.
There are many effects of biodegradable waste including less waste in garbage dumps. This means the Earth will have less waste in general.
This means disease of the kidney cells (nephrons) themselves. It usually implies less than optimal capacity to process waste (such as urinary creatinine).
i have no idea :) i thing it does something
Here are the three main parts of the excretory system and what they do:The skin - it's responsible for producing sweat, which helps regulate the salt concentration in the body. When you sweat, the salt helps evaporate the water and, in turn, cools off the body.The liver - it's part of the digestion system, but also plays a role in the excretory system. The liver has a small organelle called a peroxisome, which is responsible for taking high levels of toxicity and converting them to less toxic substances. Bile is a waste product in this process and is used in the digestive process.The kidneys - it's to remove nitrogenous wastes from the body. Nitrogenous means that it is rich in the element nitrogen. Nitrogen in high concentrations in the body can cause several problems such as joint pain, strokes or heart attacks. The kidney is made up three parts: the renal cortex, the renal medulla and the renal pelvis. All mammals have two kidneys. The kidney's primary function is to regulate various body fluids and salt concentration.
