The general functions of the lymphatic system are to collect excess tissue fluid and protein then transport them to the kidneys so they can be removed from the body as urine. to provide generic defenses against any type of invaders which happen to breach our barriers, remove any debris left after the invasion has been stopped, and then fill in the damaged area with scar tissue to collect excess tissue fluid and make it pathogen free before returning it to the bloodstream. it also transports lipids and lipid-soluble vitamins absorbed from the digestive system. to cause the breakdown of cholesterol and transports it to the liver for excretion in the digestive system. it also produces bilirubin from the breakdown of worn out red blood cells, which it excretes into the hepatic portal system.

The functions of lymphatic system are:

To provide generic defenses against any type of invaders which happen to breach our barriers, remove any debris left after the invasion has been stopped, and then fill in the damaged area with scar tissue.

The main cells of immune response are found in lymph: B and T lymphocytes are produced in lymphoid tissue (T lymphocytes mature in thymus (or tonsils)) and concentrated in the lymph nodes.

To collect excess tissue fluid and make it pathogen free before returning it to the bloodstream.

Lymphatic system drains and cleans interstitial fluid from tissue spaces and also returns leaked plasma proteins to the blood.

It also transports lipids and lipid-soluble vitamins absorbed from the digestive system.  

Big lymph vessels -lacteals are at the beginning of the gastrointestinal tract and their role is to transport fats (lipids) and vitamins to the blood circulation via the thoracic duct.

the three components of a nucleotide are the nitrogenous base, the phosphate group and the five-carbon sugar.

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
