V. Anatomy and Physiology The Urinary Tract The Urinary System rids the body of nitrogenous wastes while regulating water‚ electrolyte‚ and acid-base balance of the blood. Kidneys Kidneys are small‚ dark red organs with a kidney-bean shape lie against the dorsal body wall in a retroperineal position (beneath the parietal peritoneum) in the superior lumbar region. The kidneys extend from T12 to the L3 vertebra; thus they receive some protection from the lower part of the rib cage. Because

The Excretory System The importance of the excretory system The excretory system involves a process which removes unwanted products from the body’s chemistry. In general‚ excretion is the process of separating wastes from the body fluids and eliminating them. Examples include the removal of carbon dioxide in the air we exhale‚ and unwanted nitrogen in sweat‚ nails and hair. Explain the various methods of excretion in the human body There are four (4) organ systems which are responsible

worksheet is worth 54 points. 1. Differentiate between the afferent and the efferent arterioles. (2 points) Blood supply to the glomerulus o afferent arteriole feed the glomerular capillary bed o efferent arteriole drains the glomerular capillary bed 2. Provide a two-word description each for the renal corpuscle and renal tubules. (2 points) renal corpuscle o glomerulus & glomerular together renal tubules o reabsorption & secretion 3. What will happen to the glomerular capillary pressure and

filtered from glomerulus into Bowman’s capsule * Blood pressure forces filtrate through filtration slits between podocytes of Bowman’s capsules. * Approx 20% of blood plasma is non-selective filtered into capsule * What does this? * Renal Corpuscle * Glomerulus – capillaries! Blood supply is from the afferent arteriole. Water and solutes are filtered out from the blood into Bowman’s capsule. * Bowman’s capsule – Glomerular capsule‚ surrounds glomerulus. Inner layer

PhysioEx – Exercise 9 Activity 1: 1. excretion and regulation 2. glomerular capillaries (glomerulus) & Bowman’s capsule 3. The filtrate flows from the Bowman’s capsule into the renal tubule called the proximal convoluted tubule then into the loop of Henle‚ and finally into the distal convoluted tubule: a. Proximal Convoluted Tubule b. Loop of Henle c. Distal Convoluted Tubule 4. When the radius of the afferent arteriole was decreased‚ the pressure and the filtration rate both decreased

water‚ salt and pH balance in the body. This vital job results in the formation of urine. 1.Afferent Arteriole * receives blood rich in oxygen from the renal artery. * blood is transported to the glomerulus of the nephron where it is pressure filtered. 2.Glomerulus * The glomerulus is a knotted up capillary that contains small pores. * The plasma of the blood and the small molecules contained in plasma are pressure filtered into the Bowman’s capsule. * Large blood proteins

e functioning of the collecting ducts. 4. Which is reabsorbed by the proximal convoluted tubule cells?Na+‚K+‚ amino acids. 5. Glucose is not normally found in the urine because it is reabsorbed by the tubule cells. 6. Filtration at the glomerulus is inversely related to capsular hydrostatic pressure. 7. Tubular of glucose and many other substances is a Tm limited active transport of Na+.

Homeostasis is the maintenance of a steady state. With changes within and around living cells‚ conditions are maintained at a constant level. The ‘two major control systems‚ nerves and hormones‚ are mainly responsible for co-ordinating homeostatic mechanisms’ (Human Body) whilst using feedback. If a change in condition is detected a corrective mechanism is activated‚ conditions return to set point and the corrective mechanism is then switched off. The conditions are then at constant level. Some of
