29) There are many negative consequences for a diet high in sodium. Explain how too much sodium in the diet would affect function of the kidneys and the composition of the urine. What tubules of the kidney would be most affected? Provide 2 examples from non-human species for removal of sodium. (short answer please)
As effective filtration pressure increases: A. Glomerula filtration rate decreases. B. Filtrate production decreases. C. Gas exchange in the lungs increases. D. Reabsorption decreases in the nephron.
The forces that oppose glomerular filtration are: W. osmotic force of proteins in the glomerular capillariesX. blood pressure in the glomerular capillariesY. fluid pressure in Bowman’s capsuleZ. ATP-dependent processes in the nephron Select one: a. if only W, X and Y are correct b. if only W and Y are correct c. if only X and Z are correct d. if only Z is correct e. if all are correct
1. The location of the kidneys in the body is best described as being: In the pelvic cavity In the mediastinum retroperitoneal In the thoracic cavity 2. Place the structures of the renal tubule in the correct order from the start of filtration to completed urine in the collecting duct. descending (proximal) loop of Henle proximal convoluted tubule (PCT) distal convoluted tubule ascending (distal) loop of Henle Bowman's capsule 3. Place the structures of the blood flow in the nephron in the correct order. glomerulus afferent arteriole peritubular capillaries efferent arteriole cortical radiate veins
1. Functions of the Urinary System A. Kidneys regulate blood levels of several ions, most importantly (Na+), (K+), _(Ca2+), _(Cl-), and _(HPO42-). B. Kidneys regulate blood pH by secretion of and reabsorption of C. Kidneys regulate blood volume by conserving or eliminating D. Kidneys regulate blood pressure by secreting the enzyme which activates the RAA pathway that increases blood pressure. E. Kidneys help maintain a relatively constant blood osmolarity of F. Kidneys produce _mOsm/liter. (active vitamin D) and - the hormone that stimulates RBC production. G. Kidneys can use glutamine (amino acid) to synthesize H. Kidneys excrete wastes such as from deamination of amino acids, from catabolism of hemoglobin, from breakdown of creatine phosphate, and from catabolism of nucleic acids. 2. Matching: Kidney A. Superficial, light red region of the kidney – contains portions of the nephron such as the corpuscle and convoluted tubules. Renal hilum B. Deeper, dark reddish-brown region of the…
An increase in glomerular filtration rate (GFR) will: O Produce a myogenic response, which signals the afferent arteriole to vasodilate Stimulate the macula densa to secrete sodium Stimulate the macula densa, which signals the afferent arteriole to vasodilate Stimulate the macula densa, which signals the afferent arteriole to vasoconstrict O None of the above
3. Draw a kidney tubule cell. Be sure to label the apical and basolateral membrane. Label where the inside of the nephron tubule is located. In your drawing, add in all of the important channels and pumps for glucose reabsorption.
which of the following forms the filtration membrane, which is responsible for producing filtrate? choose all that apply: glomerulus wall, visceral layer of bowmans capsule, peritubular capillaries, parietal layer of bowmans capsule.
e The excretory system regulates the volume and composition of body fluids by removing wastes and returning useful substances to the body. Some of the characteristics of the excretory organs are given below. 1. Carries urine to the bladder 2. Stores urine 3. Eliminates urine from the body 4. Composed of nephrons Put the numbers of the above characteristics in order, so they correspond to the urinary bladder, the ureters, the kidneys, and the urethra. (Your answer should look like 1234, but that isn't the right order.) Answer: Next page OF

Lithium is a drug that is often used as a psychiatric medicine. It has the effect of blocking the production of aquaporins in the collecting duct and distal tubule, as well as damages the capillaries in the glomerulus. Q: Both protein and red blood cells are often found in the urine of those taking Lithium. Explain how this may occur.
