Part 3: Chapter 20-29 Question 11

What is a blood clot and how does it cause organ damage?

4 comments:


  1. A blood clot is coagulated blood as a result of an injury or cut. Blood clots after an injury or cut are helpful because they reduce blood loss and help the wound heal. However, not all blood clots are good. For instance, blood clots in the brain or lungs are detrimental to one’s health and can lead to a heart attack or stroke, requiring medical attention. Blood clots can move from the original source of injury and harm other parts of the body. Blood clots can damage organs because they obstruct blood flow to the rest of the body. For instance, if there is a blood clot in an artery that supplies blood to the heart, then the blood flow to the heart muscle will decrease, reducing the amount of oxygen supplied to the cells in that area. This leads to oxygen deprivation to that specific part of the heart muscle and a heart attack occurs. Strokes are caused by lack of oxygen to the brain (due to a blood clot). Therefore, it is always best to be aware of one’s health and have regular doctor visits to ensure one is healthy. It is especially important to see a doctor if one feels ill, such as disruptions in blood flow or injury to the blood vessels as this could lead to organ damage due to a blood clot.

    1. Hi Julieta, what is a brain aneurysm? Is it the same as a blood clot?

    2. A brain aneurysm is a “bulging weak area in the wall of an artery that supplies blood to the brain” ("Brain Aneurysm: Causes, Symptoms, Diagnosis, and Treatment – WebMD”). More often than not, a brain aneurysm goes unnoticed because it causes no symptoms. Brain aneurysm are hereditary; however, one may contract a brain aneurysm if the person’s arteries harden. The problem with brain aneurysm is that they cause no symptoms, so, often, people do not know they have one until they go to a doctor or until it happens. Symptoms for brain aneurysms can only be determined during tests for other, unrelated conditions or illnesses. A ruptured aneurysm causes problems because they press on other areas in the brain. Therefore, if someone suffers from severe headaches, blurred vision, sensitivity to light, changes in speech, and neck pain, then that person most likely has a brain aneurysm and it is best to see a doctor as soon as possible. Brain aneurysms is most prevalent in women, African Americans, people who smoke, people who previously had an aneurysm, and people who have high blood pressure. A brain aneurysm and a blood clot are two completely different things. An aneurysms occurs due to an enlargement or bulging of a blood vessel caused by damage to the blood vessel’s wall. On the contrary, a blood clot is a group of blood cells that clump together to stop bleeding in a cut or injury.

  2. Hey Karen, I love your input and research on blood clots. I always find the way brains are affected by blood clots the most interesting. It's interesting because I fell like the position of the blood clot near the brain is one of the only instances where even a one centimeter change in position affects something totally different. Blood clots in the brain cause many different things based on its position: "Recurring headaches...seizures...speech problems...facial weakness or paralysis...blurred vision...poor coordination" (New Health Guide). Different positions of the blood clot can affect the broca and wernicke's area, responsible for understanding and making auditory sentences, the cerebellum, responsible for coordination, and more brain sections.
