A look at the 10 systems of the human body

Sodium in biologyTubuloglomerular feedbackand Sodium-calcium exchanger The homeostatic mechanism which controls the plasma sodium concentration is rather more complex than most of the other homeostatic mechanisms described on this page. The sensor is situated in the juxtaglomerular apparatus of kidneys, which senses the plasma sodium concentration in a surprisingly indirect manner. Instead of measuring it directly in the blood flowing past the juxtaglomerular cellsthese cells respond to the sodium concentration in the renal tubular fluid after it has already undergone a certain amount of modification in the proximal convoluted tubule and loop of Henle.

A look at the 10 systems of the human body

Mind Amuse Staff 2 years ago Together, the cells make up every part of it. Human anatomy is the study of how it all works together. Cells come together to form tissues and then tissues, in turn, come together to form organs. Each organ acts in a slightly different way and has a different responsibility for the whole.

Together, when they function successfully, they allow the body to function normally and for us to do all of the amazing things that a human being can do. In total, there are more than 70 organs, and they are all important, indeed vital, in their own way.

The Bladder When we eat food some is digested and some needs to be removed from the system. These usually contain toxins that would harm the body if they were digested.

The urinary bladder performs a vital function in removing this unwanted waste from the body. It can hold between ml and ml of urine.

An overactive bladder is a common problem, with people who suffer from it feeling like they need to empty it regularly.

They then feel sharp pains as in actual fact there is nothing to release. When bacteria gets inside the bladder and multiplies it can lead to cancer. Without this organ we would be unable to remove waste efficiently. The Skin The skin is the largest organ of the human body, and many people do not usually think of it as an organ.

However, it plays a vital role in regulating the temperature of the body, ensuring it does not overheat. Goosebumps and raised hair will trap heat in the body if it is too cold and similarly sweat will keep the body cool.

Oil is the skin prevents it from drying out. It really is a vital organ. On top of everything else it ensures all of your other organs do not escape! The Small and Large Intestines Strictly speaking these should be counted as two organs but they are being counted together to keep it simple.

They are both as vital as each other. Their role is to connect the stomach, where food is broken down, to the anus, where waste is released.

They cleverly release gastric juices which separate the wanted from the unwanted nutrients. The large intestine is responsible for absorbing water and the small intestine will absorb specific nutrients that will be useful for the rest of the body. The Kidneys These are usually known to be bean shaped and they are an essential part of the urinary system.

They play a key role in filtering water and blood and also maintaining blood pressure. They can be found in the abdominal cavity. The Spleen The spleen is not often thought about but it is really important. Its job is to remove any old or damaged red blood cells from the blood, break them down and return the usable iron to the body.

It can even make new red blood cells, which is particularly important in the last month of foetal life. The stomach is, of course, responsible for breaking food down into smaller pieces, releasing enzymes and acids to help with this process and therefore playing a crucial role in the digestive system as a whole.

The Liver Without an effectively functioning liver, it would be tough for the body to function at all in the first place. It has a range of different responsibilities including synthesis of proteins, producing hormones, breaking down old red blood cells and perhaps the most important which is detoxifying food.

It is the liver that everybody thinks of when they think of drinking alcohol but if you think about it logically you are forcing your liver to work overtime by drinking the alcohol, which is a poison, so you are best off not drinking at all if you want a healthy liver. The Lungs The lungs are the most important organ in the body so far as the respiratory system is concerned.

They expand when you breathe in and contract when you breathe out. Their principal role is to exchange oxygen which is inhaled with carbon dioxide found in the blood. Smoking has a particularly negative impact on the lungs as tar builds up and covers them, making it more difficult for them to function effectively.

There are many diseases of the lungs, including Pneumonia, EmphysemaAsthma and Acute bronchitis. People who play wind and brass instruments, as well as athletes, tend to have bigger lung capacities.Following his near-fatal duel with Obi-Wan Kenobi on Mustafar in 19 BBY, Darth Vader received a mobile life support system encased in a suit of distinctive black armor.
