As the blood travels throughout the body, it picks up nutrients from the small intestine, oxygen from the lungs and hormones from the endocrine gland and delivers these materials to the cells. Once delivered, the blood picks up the waste products and carbon dioxide produced by the cells and transfers it back to the lungs. If this system stops functioning, the cells won’t get enough materials and soon they would start to die off. The circulatory system is an important system in the body that helps serve basic nutrients to cells, removes waste products, and…show more content…
Hemoglobin is an important factor that make up the red blood cell b. The hemoglobin in red cells is mixed with oxygen in our lungs. B. White blood cells are the most important part of the body’s defense system. 1.

Broken parts of the cells also help the blood circulation. 1. Platelets are small disk-shaped pieces of cells that are broken off from other cells in the bone marrow 2. Platelets help control bleeding in an interesting process call hemostasis 3. In this process when an injury occurs to a blood vessel, causing bleeding the platelets start to stick to the injured blood vessel and release chemicals to attract other platelets. 4. Then as more platelets start sticking together they soon form a temporary clot V. The blood vessels guide blood and help the blood travels through our body. A.

This stroke has a pretty accurate name “silent” because this a a symptomless stroke. 2. This stroke is caused by hypertension or high blood pressure. 3.
