The structure of the Senate differs from that of the House of Representatives in various key aspects. The Senate consists of two members from each state, regardless of population, totaling 100 senators, while the House's membership is based on state population, currently totaling 435 representatives. Senators serve longer terms of six years, with staggered elections, promoting continuity, whereas House members serve two-year terms, encouraging responsiveness to public opinion. Additionally, the Senate has unique responsibilities such as confirming presidential appointments and ratifying treaties, reflecting its role in maintaining a check on executive power.
