How does the blood help to maintain homeostasis?
A. It delivers nutrients to the cells.
B. It delivers oxygen to the cells.
C. It helps to transport waste out of the cells and body.
D. It carries carbon dioxide away from the cells to be breathed out of the body.
E. All of the above.
E. All of the above.
E. All of the above.
The blood helps to maintain homeostasis by performing various functions. These include delivering nutrients to the cells, delivering oxygen to the cells, transporting waste out of the cells and body, and carrying carbon dioxide away from the cells to be breathed out of the body. All of these functions are crucial for the body to function properly and maintain a stable internal environment.
The correct answer is E. All of the above.
The blood plays a crucial role in maintaining homeostasis, which is the body's ability to maintain a stable internal environment. Here's how each of the options contributes to this process:
A. The blood delivers nutrients to the cells: Blood transports important nutrients such as glucose, amino acids, and fatty acids to cells throughout the body. These nutrients are essential for energy production, growth, and repair.
B. The blood delivers oxygen to the cells: Oxygen is carried by red blood cells and delivered to the body's tissues. Cells require oxygen for aerobic respiration, which is necessary for the production of energy.
C. The blood helps to transport waste out of the cells and body: Metabolic waste products, such as carbon dioxide, urea, and lactic acid, are picked up by the blood from cells and transported to organs responsible for elimination. This includes the lungs for the removal of carbon dioxide and the kidneys for the elimination of waste products in urine.
D. The blood carries carbon dioxide away from the cells to be breathed out of the body: Carbon dioxide is a waste product produced by cells as a result of cellular respiration. It is transported via the blood to the lungs, where it is exhaled during respiration.
Therefore, all of the options mentioned play a role in maintaining homeostasis by ensuring nutrient delivery, oxygenation, and waste removal in the body.
