L'œsophage (anatomie)
L'œsophage relie le pharynx à l'estomac. Son rôle est d’assurer la descente des aliments. L’œsophage est composé de 3️⃣ segments dont : 👉 L’œsophage cervical : qui fait directement suite au pharynx 👉 L’œsophage thoracique : qui chemine dans le thorax puis traverse le diaphragme 👉 L’œsophage abdominal : qui s’abouche dans l’estomac au niveau du cardia
🔬 Understanding Urine Formation in the Nephron 🩺
This simplified diagram explains the journey of filtration, reabsorption, and secretion during urine formation in the kidneys: ✔️ Filtration: Happens in Bowman’s capsule, where blood is filtered. ✔️ Reabsorption: Vital nutrients like glucose, amino acids, and ions (e.g., Na+, Cl-) are absorbed back into the bloodstream in the proximal tubule and Henle’s loop. ✔️ Secretion: Waste products like H+, NH3, and creatinine are actively removed to form urine. 💡 A fundamental process in human physiology that highlights how our kidneys maintain balance and remove waste efficiently!
