Activity 1C: Thrombolina Casts Her Nets: Blood Clotting Activity Suggestion

Our bodies have an amazing array of defense mechanisms to protect us from disease and injury. One of these mechanisms, hemostasis, is responsible for maintaining the integrity of our circulatory system when it is breached by an injury. A physical or chemical trauma to a blood vessel begins this hemostatic mechanism, which in most cases (e.g. a trauma of some type) can save our life, but in others (e.g. atherosclerosis, deep vein thrombosis or pulmonary embolism) can severely compromise our health.
Hemostasis simply means “blood stopping”. When a blood vessel is injured and blood is escaping hemostasis is the process responsible for stopping blood leakage. An understanding of these processes provides an insight into the homeostatic processes of the body, a basic understanding of how to appropriately respond in a hemostatic emergency, knowledge of how structure and function complement one another in the cells, factors and proteins involved in the process, and an awareness of how lifestyle choices can affect health over our lifetime. At the same time students practice crucial intellectual/academic skills such as sequencing, analyzing, critical thinking and constructing models.
