The two main substances transported through phloem tissue are sugars (such as sucrose) and amino acids. These substances are transported from the leaves, where they are produced through photosynthesis or other metabolic processes, to other parts of the plant for growth and metabolism.
oxyen and carbon dioxide
Only Urine.
Oxygen and carbon dioxide are two substances transported in the blood. Oxygen is carried from the lungs to body tissues by red blood cells, while carbon dioxide is transported from body tissues back to the lungs for elimination.
In a normal healthy male, the only two products that pass through the urethra are urine and semen.In times of disease however, other products that may also be passed through the urethra are pus and blood.
Oxygen is delivered from the lungs to the cells of the body through blood, and waste products from cells are delivered back to the lungs for exhalation.
The two systems involved in excretion are the urinary system and the digestive system. The urinary system removes waste products from the blood and produces urine, while the digestive system eliminates solid waste products from the body through feces.
Sugars (mainly glucose) produced through photosynthesis in the leaves are transported to the rest of the plant body for energy and growth. Additionally, water and minerals absorbed by the roots are also transported to the leaves through the xylem tissue.
Natural gas and petroleum.
The urinary system is composed of the kidneys, ureters, bladder, and urethra. The kidneys filter waste and excess fluids from the blood to form urine, which then travels through the ureters to the bladder for storage, and is eventually eliminated from the body through the urethra.
There are two types of vascular tissue that aid in transport and there are two substances that are transported. Xylem transports water and dissolved minerals and phloem transports sugar (sap).
Heat is primarily transported in the biosphere through conduction, where heat is transferred through direct contact between molecules, and convection, where heat is carried by the movement of fluids such as air or water.
