Disorders of the kidney encompass a wide range of conditions that affect the structure and function of the kidneys, leading to impaired filtration, secretion, reabsorption, and excretion of substances. These disorders can be congenital or acquired and may affect one or both kidneys. Let’s explore some of the most common …
Renin-Angiotensin-Aldosterone System (RAS)
Renin-Angiotensin-Aldosterone System (RAS) a pivotal role in regulating blood pressure, fluid balance, and electrolyte homeostasis, with the kidneys serving as a central component in its function. The RAS is a crucial physiological mechanism that helps maintain systemic blood pressure and fluid volume within narrow limits. Let’s delve into a detailed …
Role of kidneys in acid base balance
The kidneys play a crucial role in maintaining acid-base balance in the body through processes of filtration, reabsorption, secretion, and excretion of ions and molecules involved in regulating pH levels. The acid-base balance is essential for normal physiological functions, as even slight deviations from the optimal pH range can disrupt …
Micturition reflex: Definition, Anatomy, and Phase
The micturition reflex, also known as the urination reflex, is a complex neurophysiological process that controls the initiation and coordination of urination (voiding of urine) from the urinary bladder. It involves both voluntary and involuntary components and requires the integration of sensory, motor, and autonomic nervous system pathways. Let’s delve …
Physiology of urine formation
The process of urine formation, also known as renal physiology, involves intricate mechanisms that regulate the composition and volume of urine produced by the kidneys. It consists of three main processes: glomerular filtration, tubular reabsorption, and tubular secretion. Let’s explore each in detail: 1. Glomerular Filtration: Glomerular filtration occurs in …
Anatomy of kidney and nephrons
The kidneys are vital organs responsible for maintaining fluid balance, electrolyte levels, and the removal of waste products from the bloodstream. Within the kidneys, nephrons are the functional units responsible for these processes. Let’s explore the anatomy of the kidneys and nephrons in detail: Anatomy of the Kidneys: 1. Location …
Urinary system: Anatomy of urinary tract
Anatomy of the Urinary System The urinary system, also known as the renal system, is responsible for the production, storage, and elimination of urine, which is the primary method by which the body rids itself of waste products and regulates various metabolic processes. The anatomy of the urinary tract encompasses …
Artificial respiration and resuscitation methods
Artificial respiration and resuscitation methods are life-saving techniques used to restore or maintain breathing and circulation in individuals experiencing respiratory or cardiac arrest. These techniques are crucial for providing immediate assistance until advanced medical care can be administered. 1. Artificial Respiration: Artificial respiration, also known as assisted ventilation, involves providing …
Transport of respiratory gases
The transport of respiratory gases refers to the movement of oxygen (O2) and carbon dioxide (CO2) between the lungs and the tissues via the bloodstream. This process is essential for cellular respiration, where O2 is delivered to tissues for energy production, and CO2, a waste product of metabolism, is removed …
Lung volumes and capacities
Lung volumes and capacities refer to the different measurements used to describe the amount of air in the respiratory system at various stages of the breathing cycle. These measurements provide valuable information about lung function and respiratory mechanics. Here’s a detailed note on lung volumes and capacities: 1. Lung Volumes: …
