Meats, cheeses, and eggs can provide a great source of Vitamin K2.
- 10. Blood flow to a tissue will increase if the
Options- A. pH rises
- B. Level of carbon dioxide at the tissue increases
- C. Vessels constrict
- D. Level of oxygen at the tissue increases Also asked in: AIEEE, Bank Exams, Analyst, Bank Clerk, Bank PO
Correct Answer: Level of carbon dioxide at the tissue increases
Explanation:
The movement of blood in the body is called blood flow. The blood flows through the vessels, tissues and organs. Blood flow to a tissue will increase if the level of carbon dioxide at the tissue increases.
