Each kidney is surrounded by three main layers. From outermost to inner-most, the layers are as follows: Renal capsule – connective tissue that helps maintain the kidney’s structural integrity and shape, protecting its internal tissue (Cook et al, 2021b).
The lungs and kidneys work together to produce a normal extracellular fluid and arterial pH of 7.35-7.45 (34-46 nmol.l-1 H+ concentration). Carbon dioxide (CO 2), when dissolved in the blood is an acid, and is excreted by the lungs. The kidney excretes fixed acid and performs three functions to achieve this:-1. Tubular secretion of acid (figure ...
FUNCTIONAL RENAL ANATOMY Each kidney in an adult weighs about 150 g and is roughly the size of one’s fist. If the kidney is sectioned (Fig. 23.1), two regions are seen: an outer part, called the cortex, and an in-ner part, called the medulla. The cortex typically is reddish brown and has a granulated appearance. All of the glomeruli,
Kidneys are involved in the mainte-nance of the fluid and electrolyte levels, acid- base balance, filtration and excretion of metabolic waste such as urea and ammonium, stimulate red blood cell (RBC) synthesis, and regulation of blood pressure through the renin-angiotensin- aldosterone system and other mechanisms.
The basic anatomy and physiology of the kidney How kidney function changes through life . The Anatomy of the Kidney. The kidneys are complex and beautiful organs. Their internal structure is revealed by anatomical studies using light and electron microscopy (Figs. 1.1 , 1.2 , 1.3 , 1.4 and 1.5 ). Turning Blood into Urine.
• The gross structure of the kidney, which is a cortex surrounding a medulla containing an inner cavity, the pelvis • The functional unit of the kidney – the microscopic nephron (1 million in each kidney) • How about 180 litres of plasma filters into the nephrons each day and how most of it is reabsorbed • Autoregulation of renal ...
Each kidney has an outer cortex and an inner medulla. Medulla is composed of about 12 renal pyramids. The base of each pyramid is directed toward the cortex and its apex (the renal papilla) is projecting medially. The cortex extends into the …
