The skin is utilized in many ways. Firstly, it traps moisture in every part of your body. Secondly, it regulates your body temperature. The salt found in the skin helps during evaporation to cool of those who are hot. Sweat is also a part of this, and come from sweat glands in the skin. Sweating allows people to remain cool during warm temperatures.
Any waste that is found in the bodies are transferred quickly to the kidneys. The kidneys remove any waste from the blood transferred to it. Then, the kidneys proceed to send wastes in the blood, including urea, salts, and excess water, out to be excreted in the form of urine.
The first thing the liver does is tell the gallbladder to release bile into the intestines so that any fatty foods can be broken down and waste can be sent to the intestines. The intestine absorbs most of the fat into the bloodstream, and that blood is delivered to the liver. The liver proceeds to remove any remaining waste from the blood, along with any iron.
Your lungs play an important role in removing the carbon dioxide from your body. Special cells remove this from your blood, and allow you to breathe it out. If your lungs did not enable you to do this, the carbon dioxide would build up and cause all kinds of issues in your body.
The kidneys are bean shaped organs that help to filter out any waste, water, and salt from within the body. The kidneys are connected to the aorta, which is the main artery of the body, and above each of them are an adrenal gland. The kidneys contain two distinct regions, namely the renal cortex, which is the outer portion, and the renal medulla, which is the inner area. Each part of the kidney contains many microscopic blood vessels and tubes. In the center region of every kidney is a place called the renal pelvis, which is primarily when urine collection happens. The other main areas are the renal artery and renal vein. The renal artery works to bring oxygenated blood to the kidney, and the renal vein brings deoxygenated blood from veins within the kidney and return it to the circulatory system.
