Final answer:
Blood helps maintain homeostasis and proper body function through various mechanisms such as clot formation, protection against foreign substances, transport of gases, nutrients, and waste products, and maintaining normal fluid and ion balance.
Therefore, the correct answer is option e). all of the above.
Step-by-step explanation:
Blood helps maintain homeostasis by stabilizing pH, temperature, osmotic pressure, and by eliminating excess heat. Blood supports growth by distributing nutrients and hormones, and by removing waste.
Red blood cells contain hemoglobin, which binds oxygen. The brain monitors changes in the body energy state by sensing alterations in the plasma levels of key metabolic hormones and nutrients.
It does so through various mechanisms:
- Platelets facilitate clot formation to prevent excessive blood loss.
- Leukocytes provide protection against foreign substances.
- Blood enables the transport of gases, nutrients, and waste products.
- Its osmotic composition is important for maintaining normal fluid and ion balance.
Therefore, the correct answer is e. all of the above.
