Which of the following statements is correct?
- AThe contraction of heart muscle causes blood to enter arteries that pump the blood to organs, causing the formation of tissue fluid between cells before returning to the heart in veins.
- BThe heart connects two types of blood vessels so that oxygen from the lungs can be distributed by red blood cells and wastes can be collected from tissues directly into blood plasma for removal.
- CThe heart muscle contracts and relaxes which causes molecules such as carbon dioxide and antibodies to be transported in blood plasma through blood vessels that connect different parts of the body.
- DThe heart provides enough pressure to push blood through arteries to capillaries between cells, causing filtration of blood and the formation of tissue fluid which diffuses back into veins.
