What is the most likely affect a blood clot will have on blood flow through the cardiovascular system?

• A blood clot will increase blood flow in other areas, allowing more oxygen to reach tissue in those areas.
• A blood clot will change the direction of blood flow, allowing oxygen to reach tissue in a new area.
• A blood clot will not change blood flow, allowing the same amount of oxygen to reach tissue in a certain area.
• A blood clot will block blood flow, preventing oxygen from reaching tissue in a certain area.

Elasticity in blood vessels allows the vessels to stretch and move based on changes in blood volume. A number of factors, including genetic disease, can cause the arteries to harden and lose their elasticity. How would the hardening of the arteries most likely affect blood flow?

• The hardening of the arteries would likely cause blood flow to remain constant.
• The hardening of the arteries would likely increase blood flow.
• The hardening of the arteries would likely cause blood flow to stop completely.
• The hardening of the arteries would likely restrict blood flow.
