Anatomy, Physiology, and Pathologies of Human Arteries

ЁЯФ╣ Why in News & Recent Development

Recent clinical insights highlight that pain in the legs during walking serves as an early clinical warning sign of peripheral artery disease (PAD), highlighting the critical physiological role and vulnerability of the human arterial network.

ЁЯФ╣ Key Conceptual & Analytical Details

Arteries are specialized blood vessels comprising roughly 10% of total body blood volume at any given time, tasked with delivering oxygen-rich blood from the heart's aorta to all body cells. Structurally, arteries possess three distinct layers: the inner tunica intima (containing elastic fibers), the middle tunica media (smooth muscle regulating vessel lumen diameter), and the outer tunica externa. They are categorized into elastic arteries (e.g., aorta and pulmonary artery) close to the heart and muscular arteries (e.g., femoral, radial, and brachial) further down the systemic circuit.

ЁЯФ╣ Strategic Importance & Future Impact

Understanding arterial mechanics is paramount for managing cardiovascular disorders such as atherosclerosis (plaque accumulation leading to luminal narrowing), aneurysms, and localized organ-specific ischemic conditions affecting critical beds like the carotid (brain), coronary (heart), and renal/mesenteric arteries.

UNSC Veto Power Reforms and Global Governance Debate

ЁЯФ╣ Why in News & Recent Development

During the 81st Session of the United Nations General Assembly (UNGA), member states engaged in intense debates concerning structural reforms of the United Nations Security Council (UNSC) veto power, especially in the wake of prolonged institutional paralysis during severe humanitarian crises.

ЁЯФ╣ Key Conceptual & Analytical Details

While the term 'veto' does not explicitly appear in the UN Charter, Article 27(3) establishes that substantive non-procedural decisions require nine affirmative votes alongside the concurring votes of all permanent members (P5: China, France, Russia, UK, and USA). A negative vote by any permanent member blocks resolution adoption. India continues to advocate for comprehensive reforms, opposing a two-tier permanent membership and working alongside the G4, L.69 Group, and Ezulwini Consensus.

ЁЯФ╣ Strategic Importance & Future Impact

Unchecked veto power creates an undemocratic oligopoly that violates the sovereign equality of member states, fostering geopolitical gridlock. Restructuring the UNSC is vital for elevating Global South and African representation, ensuring global multilateral legitimacy in the 21st century.
