No, cholesterol does not float freely in the bloodstream. It is transported in the blood attached to proteins called lipoproteins, such as LDL and HDL. These lipoproteins help transport cholesterol to cells throughout the body.
down to the bladder via the uriters, then out. Urine from each kidney drains through a tube called a ureter and collects in the bladder. As the bladder fills, its muscular wall stretches. When it is full, receptors in the wall send a signal to the brain and trigger the urge to urinate. During urination the muscles that close the bladder exit relax to release the urine.
The blockages is called an emboli. It can be caused by a blood clot, air bubble, fatty deposit, or other object that has been carried in the bloodstream to lodge in a vessel.
Endocrine glands secrete chemical messengers called hormones. These chemicals are secreted directly into the bloodstream, where they are carried by the circulatory system to target tissues throughout the body.
Animals get oxygen for cell respiration from the air through a process called breathing. Oxygen is inhaled into the lungs where it enters the bloodstream and is carried to the cells throughout the body.
The waste form of nitrogen formed in the liver and carried in the bloodstream is urea. Urea is produced in the liver through the breakdown of proteins and is removed from the body through the kidneys in urine.
It is called urea
First blood is carried into the kidneys by the renal artery anything in the body related to the kidneys is called renal

Excess nitrogen is converted into urea by the liver through a process called the urea cycle. Urea is then excreted in urine by the kidneys to maintain nitrogen balance in the body.
The tube that carries urine from the bladder to the outside of the body is called urethra.Urine is carried from the kidneys to the bladder by the ureters and it is carried out of the body by the urethra
The conversion of ammonia and other nitrogen-containing nutrients into nitrogen gas is called denitrification. This process is carried out by denitrifying bacteria in the soil or aquatic environments and results in the release of nitrogen gas back into the atmosphere.
The conversion of ammonia and other nitrogen-containing nutrients into nitrogen gas is called denitrification. This process is carried out by denitrifying bacteria in anaerobic conditions, where they convert nitrate (NO3-) into nitrogen gas (N2) to release it back into the atmosphere.
No, cholesterol does not float freely in the bloodstream. It is transported in the blood attached to proteins called lipoproteins, such as LDL and HDL. These lipoproteins help transport cholesterol to cells throughout the body.
The process by which nitrogen gas is converted into a usable form for life is called nitrogen fixation. This process is carried out by certain types of bacteria and archaea, which convert nitrogen gas into ammonia or other nitrogen-containing compounds that can be used by plants and other organisms.
