Why does clotting of blood not take place in uninjured blood vessels?
Blood clotting does occur for blood in uninjured blood vessels due to its insulation from air. Our bodies produce what is called heparin that prevents clotting of blood in vessels. Heparin allows our lungs to transfer oxygen to our blood. When blood is exposed to air it clots so heparin allows the blood to come in direct contact with the air we breath without clotting.
What processes is triggered when blood contacts damaged blood vessels or tissues outside blood vessels?
Clotting factors will be activated.
Damage to the small blood vessels can cause what to occur?
The organism not only damages the blood vessels by causing them to leak, but also causes clotting inside the vessels.
Which is best suited to the clotting process that occurs when blood vessels are ruptured?
Platelets
What is the function of the blood platelets?
Platelets help close breaks in damaged blood vessels and initiate formation of blood clots.
The blood platelets accumulation during blood clotting in response to any damage to the lining of the blood vessels is?
a negative feedback mechanism
What is a component blood that lacks a nucleus and assists in blood clotting?
Platelets are cell fragments that lack a nucleus and are key players in the blood clotting process. They help to seal off leaks in damaged blood vessels by sticking to the injured area and releasing chemicals that promote clotting.
Why does the blood stop clotting in diabetes?
In diabetes, high blood sugar levels can damage blood vessels and interfere with the normal clotting process. Additionally, diabetes can lead to changes in blood composition that affect the clotting mechanism, making it less effective. This increased risk of impaired clotting in diabetes can result in difficulties in stopping bleeding and an increased risk of excessive bleeding.
Does alum effectively stop bleeding"?
Yes, alum can effectively stop bleeding by constricting blood vessels and promoting blood clotting.
How does a blood thinner work to prevent blood clots?
Blood thinners work by interfering with the body's blood clotting process. They can either prevent the formation of blood clots or break up existing clots. This helps to reduce the risk of dangerous clotting in the blood vessels.
What chemical constricts blood vessels until clotting occurs?
antidepressants and smoking
What are Fragments of cells that form a plug sealing holes in injured vessels during blood clotting?
platelets
