The decrease in total peripheral resistance to blood flow is - b. anemia.
Peripheral resistance is the resistance of the arteries to blood flow. The resistance increases with the constriction of arteries and decreases with dilatation. It creates blood pressure in the arteries against blood circulation.
Effect of anemia:
- An abnormally low hematocrit level shows that cells may not be getting enough oxygen, a condition known as anemia
- Hematocrit is the percentage by volume of red cells in your blood.
- Anemia reduces blood viscosity, decreasing total resistance because of enhanced nitric oxide-mediated vasodilation.
Thus, The decrease in total peripheral resistance to blood flow is - b. anemia.
