The overall function of the digestive system as digestion and absorption of food stuffs, and the general activities of each digestive system organ is; Ingest, digest, absorb, defecate.
Ingestion involves placing food into the mouth, propulsion involves propelling food from one organ to the next using peristalsis. Mechanical digestion involves the physical fragmenting food into smaller particles. Chemical digestion refers to breaking down food molecules to building blocks by enzymes. Absorption is the transport of digested end products to blood or lymph; and finally Defecation which involves the elimination of indigestable material from GI tract by anus.
Question is incomplete, the complete question is as follows :
Clotting begins when a _________ occurs in a blood vessel wall. Almost immediately, _______ cling to the blood vessel wall and release _____________ which helps to decrease blood loss by constricting the vessel. __________ is also released by damaged cells in the area. This chemical substance causes ________to be converted to ____________. Once present, thrombin acts as an enzyme to atatch ___________molecules together to form long, threadlike strands of _________, which then traps ____________ flowing by in the blood.
Answer:
Clotting begins when a <u>BREAK</u> occurs in a blood vessel wall. Almost immediately, <u>PLATELETS</u> cling to the blood vessel wall and release <u>SEROTONIN</u>, which helps to decrease blood loss by constricting the vessel. <u>THROMBOPLASTIN</u> is also released by damaged cells in the area. This chemical substance causes <u>PROTHROMBIN</u> to be converted to <u>THROMBIN</u>. Once present, thrombin acts as an enzyme to attach <u>FIBRINOGEN</u> molecules together to form long, threadlike strands of <u>FIBRIN</u>, which then traps<u> ERYTHROCYTES </u>flowing by in the blood.
This should be the answer for the Krebs cycle
