Essays on Reabsorption

Hypertension in children is becoming a growing healthcare concern in America. It is quite common to see reports of hypertension in children. Most cases of hypertension in children remains undiagnosed and therefore the present prevalence is an underestimation of the real scenario. Unlike adults, the normal blood pressure values in children can vary based on their age and height, and thus borderline cases of hypertension, escape diagnosis. Sedentary lifestyle and obesity are important risk factors for hypertension in children. Through proper lifestyle practices and diet, hypertension can be prevented in children. Preventing hypertension in children is important as hypertension ...

Question 1: Pathophysiology of Mr. Jensen’s post-operative hypovolemia

Hypovolemia is a surgical condition that indicates the rapid fluid loss that may result in organ failures. The outcomes of the hypovolemia are mostly due to insufficient circulating volume or scarce perfusion. Often hypovolemia is secondary to hemorrhage the reason of which includes severe internal or external blood loss and GI, thoracic and abdominal bleeding maladies (Devitt, 2001). Hypovolemia involves significant fluid loss other than blood that can be further accompanied by refractory gastroenteritis and widespread burns. Hypovolemia may develop in post-surgical incidence, bone fracture, due to ...

Absorption

Absorption is the process through which biomolecules traverse through the GI tract into the circulatory system. Digested food gets absorbed in the small intestinal lumen through four processes, which include active transport, passive transport, endocytosis and facilitative diffusion. The efficiency of absorption of nutrients may be attributed to the large surface area lined up with hair like projections and microvilli cells .

Excretory System

Excretion is the mechanism through which waste products and eliminated from the body and osmotic pressure and homeostasis is achieved in the body . The process of excretion in the body takes place in three stages: filtration, reabsorption and ...

Urinary System

Kidneys are the main organs of the urinary system that filter around 200 liters of blood and purify it through excreting excessive water, toxins, electrolytes and metabolic wastes that assist in maintaining body’s fluid equilibrium. The other components of the urinary system are ureters, urethra and urinary bladder (Marieb & Hoehn, 2003). The urinary system can be differentiated into main four parts, kidney, bladder, ureters, and urethra. Kidneys are secured by the tri-layered arrangement that includes an outer renal fascia composed of fibrous connective tissues, a middle ...

Diuretics targets to lower sodium and water reabsorption that may lead to enhanced water excretion. The main aim of diuretics is to reduce the fluid volume inside the body and maintain the electrolyte and water equilibrium. These agents are used for managing the pathological conditions including hypertension and edema such as cardiac congestion failure, liver and kidney problems, and glaucoma. It also helps in processing and regulating the blood pressure by eliminating the excessive salt from the body which slows down the cardiac muscles to impel the ...

Assignment 2

PART A - (Total 15 marks)

Cephalexin and Gentamicin The mechanism of action of amoxicillin is focused on the prevention of the synthesis of the bacteria’s cell wall through the binding and inhibiting of the cell wall transpeptidases (Katzung, Masters, and Trevor, 2012). Specifically, it attaches to the penicillin-binding protein 1A found in the cell wall of bacteria. Then, the agent disintegrates the lactam ring to allow the acylation of the penicillin-sensitive transpeptidase C-terminal domain. The formation of the cross-link of the linear peptidoglycan strands is prevented by the inactivation of transpeptidases. Since the third and last stage ...

Magnesium is an essential nutrient

Magnesium is a mineral which is of great abundance in the human body. Along with enzymes, it is important for protein synthesis, muscle regulation and a host of other important cellular factors such as oxidative phosporylation, energy production which involves production and utilization of ATP and glycolysis. Additionally, Magnesium is required to assist in different cellular processes such as DNA replication and transcription and RNA translation(Barbagallo, 2012). Magnesium is found usually in the bones and or in the soft tissues of humans. Next to Potassium, it is the most abundant ion in the body. The plasma actually contains ...

1.0 Overview of urine formation The kidney is the chief regulator of all body fluids primarily responsible for maintaining homeostasis (equilibrium) of fluids and electrolytes (salts) in the body[ CITATION LAK03 \l 2057 ]. The kidney has five main functions namely: regulation of fluid and electrolyte, regulation of acid-base balance, excretion of the waste products of protein metabolism, hormonal function and protein conservation. All kidney functions except the hormonal function are carried out through urine formation which involves three processes: filtration, re-absorption and secretion. These processes occur at different parts of the nephron, the basic functional unit of the ...

The Interdependency of the Digestive System, Respiratory System, and Cardiovascular Systems

In the supply, of nutrients and the removal of waste products in the human system, four organ system are involved; the digestive system, the circulatory system, respiratory system and excretory system. The digestive system comprises of the mouth, stomach, small intestine and the liver.

The digestion of the carbohydrate begins in the mouth. The predominant carbohydrate is the starch. In the mouth, enzyme salivary amylase hydrolyses the starch to disaccharides and trisaccharide. The remaining starch from the mouth is taken to the duodenum, the upper chamber of the small intestine where it is hydrolyzed by enzyme pancreatic amylase. The ...
