Which of the following tissues is most affected due to the deficiency of oxygen?

• A. Cardiac muscles
• B. Visceral muscles
• C. Hyaline cartilage
• D. Long bones

Answer 1

The correct option is A Cardiac muscles

When oxygen demand increases, heart rate and cardiac output increase, which increases the flow of blood through the lung and the pressure required to force blood through the arterioles and capillaries of the lung. Due to this, the cardiac muscles are most affected due to deficiency of oxygen. So, the correct option is 'Cardiac muscles'.
