Answer:
Circulatory system remove waste from the cell and provide clean blood to the cell.
Explanation:
During cellular respiration, lungs inhale oxygen which stored in the alveoli. The red blood cells contains hemoglobin that carries deoxygenated blood containing carbondioxide from the cell in the veins to the heart and unload this carbondioxide gas in the alveoli of the lungs and load oxygenated blood having oxygen from the alveoli through capillaries in order to provide oxygen to the cells that is necessary for the survival of humans. Platelets are the type of cells that helps in blood clotting whereas white blood cells provides immunity against pathogens.
The role of DNA in all cells is to produce molecules of RNA that are involved in protein synthesis. Through the proteins, all the metabolism of the cell is controlled. DNA is also used to synthesize new DNA for daughter cells.
Answer:
Proteins, Liver, Osmotic, Fluid, Into The Blood, Decrease.
Explanation:
Blood is considered a colloid because it contains proteins in the plasma.
Most of these are produced by the liver.
Collectively, these substances exert osmotic pressure and prevent the loss of fluid from the blood as it moves through the capillaries.
The pressure exerted by the plasma proteins is called colloid osmotic pressure.
This force is responsible for moving fluids into the blood and preventing excess fluid loss between blood capillaries and the interstitial fluid.
If plasma protein levels decrease, colloid osmotic pressure will decrease.
I hope this answer helps.
