Plants absorb essential raw materials such as nitrogen, phosphorus, and minerals from the soil through their roots.

The lymphatic system plays a crucial role in immune function, fat absorption, and fluid balance in the body. It helps to remove waste, toxins, and excess fluid from tissues, and transports immune cells to fight infection and disease.

Blood plasma is the fluid component of blood that contains proteins and other substances, while lymph is similar to plasma but lacks the red blood cells and is colorless with fewer proteins.

Lymph carries digested and absorbed fat from the intestine and drains excess fluid from the extracellular space back into the blood, helping to maintain fluid balance in the body.

Lymphatic capillaries collect the tissue fluid or lymph from the intercellular spaces in tissues. These capillaries join to form larger lymph vessels, which eventually empty into larger veins.
