Hb A1C Test Blood test used to: diagnose diabetes identify people at risk of developing diabetes monitor how well blood sugar levels are being controlled by the diabetic patient Fasting Blood Sugar (FBS) Test performed on blood to determine the level of sugar in the bloodstream. Also ref...

Heart Chambers

By: Administrator, Views: 10753

Circulation of blood through the chambers of the heart Septum divides heart into the right and left heart. Each side contains an upper and lower chamber: Atria, or upper chambers, receive blood. Ventricles, or lower chambers, pump blood. Valves control intake and outflow of blood in chamber...

Acid-base imbalances - compensation of metabolic acidosis and alkalosis

By: HWC, Views: 7997

1. Metabolic acidosis: • Few HC03- ions are present so blood pH becomes acidic. • Compensation is increased respiratory rate and more CO2 is removed from the blood. • Blood pH returns to normal. 2. Metabolic alkalosis: • Many HC03- ions are present so blood pH becomes alkaline...

The primary factors that affect circulation - MABP, CO and SVR

By: HWC, Views: 8052

Introduction Blood flow is determined by the relative intensities of factors that drive and resist moving blood. • Cardiac output (CO) equals the mean arterial blood pressure (MABP, a driving force) divided by systemic vascular resistance (SVR, a resisting force). • Hormones and the cen...

Role of the respiratory system - effect of altered ventilation rates

By: HWC, Views: 7588

• Dissociation of the chemical substances in the body fluids can result in the production of free hydrogen ions. • The pH scale is used to measure the concentration of hydrogen ions in solution. • Normal blood pH values vary around 7.4. • When hydrogen ion concentration increases, t...

Glomerular filtrate rate: pressures that affect GFR, NFP & GFR and blood composition

By: HWC, Views: 8203

• The glomerular filtration rate is the amount of filtrate formed per minute within the renal corpuscle. • Once the filtrate is formed it moves down the tubule. • The production and movement of filtrate depends on three pressures: I. Glomerular blood hydrostatic pressure (GBHP) is ...

Acid-base imbalances - compensation of respiratory acidosis and alkalosis

By: HWC, Views: 7856

• When one pH balancing system is affected then the other balancing system attempts to correct, or compensate for, the pH imbalance. - Respiratory acidosis: • Excessive CO2 is present so blood pH becomes acidic. • Compensation is increased secretion of H+ into urine and reabsorption ...

Antidiuretic hormone (vasoconstriction, water reabsorption & sweat inhibition)

By: HWC, Views: 7606

• Dehydration, blood loss, and low amounts of water in the blood can cause blood volume and pressure to decrease. • Neurosecretoxy cells in the posterior pituitary release antidiuretic hormone(ADH). • ADH binds to smooth muscle cells in blood vessel walls, stimulating them to vasoconstr...

Glomerubular filtrate rate -pressures that affect GFR and net filtration pressure

By: HWC, Views: 8178

• The glomerular filtration rate is the amount of filtrate formed per minute within the renal corpuscle. • Once the filtrate is formed it moves down the tubule. • The production and movement of filtrate depends on three pressures: I. Glomerular blood hydrostatic pressure (GBHP) is pre...
