An advanced quiz on blood components and kidney function.

📖 Core Concepts Review

Component	Primary Function	Key Concepts
🩸 Blood Components	Transport, defense, clotting	Plasma, Erythrocytes (RBCs), Leukocytes (WBCs), Platelets
🚽 Excretory System	Filter blood, regulate fluid/electrolytes, remove waste	Kidney, Nephron, Ureters, Bladder
🔧 Nephron Processes	Functional unit of the kidney	Filtration (Glomerulus), Reabsorption (PCT), Secretion (DCT)

Problem 1: Coagulation Cascade

Medium

BloodCoagulationEnzymes

The blood clotting (coagulation) cascade is a series of enzymatic reactions culminating in the formation of a clot. The final two steps of this common pathway are:

Platelet plug formation → Conversion of fibrin to fibrinogen

Conversion of prothrombin to thrombin → Conversion of fibrinogen to fibrin

Release of thromboplastin → Activation of Factor X

Vasoconstriction → Conversion of thrombin to prothrombin
