The renal pelvis is the funnel-shaped basin (cavity) that receives the urine drained from the kidney nephrons via the collecting ducts and then the (larger) papillary ducts. Renal artery: The renal artery delivers oxygenated blood to the kidney. This main artery divides into many smaller branches as it enters the kidney via the renal hilus.
Nephron • Functional unit of the kidneys • Over 1 million in each • Functions include: –filter blood –perform selective reabsorption –excrete unwanted waste products from the filtered blood See slide 10 9
This interactive application shows the anatomy of the kidney and urinary tract for males and females. It also covers internal structure of the kidney and nephrons, the blood flow through the kidney and the process of urine formation.
Each consisting of a glomerulus and Bowman’s capsule, the renal corpuscles form the filtration centres of the structural and functional units of the kidney, the nephrons, discussed below. The cortex also contains a high density of blood vessels, which serve the nephrons.
3 lis 2023 · Ultrastructurally, the nephron is the functional representative of the kidney. Each nephron contains arenal corpuscle, which is the initial component that filters the blood, and a renal tubule that processes and carries the filtered fluid to the system of calices.
Here’s how kidneys perform their important work: 1. Blood enters the kidneys through an artery from the heart 2. Blood is cleaned by passing through millions of tiny blood filters 3. Waste material passes through the ureter and is stored in the bladder as urine 4. Newly cleaned blood returns to the bloodstream by way of veins 5.
Nephron Structure The nephron the unit of filtration in the kidney. Each kidney contains at least a million nephrons. A nephron is composed of a capsule (Bowman’s capsule) into which fluids and dissolved molecules and ions are squeezed under pressure. This fluid then passes through a
