Exam 25: The Urinary System

The fetal kidneys begin excreting urine by the third month of development, thus contributing most of the volume of the amniotic fluid.

What is the structure or area that the arrow is pointing to?

The indentation on the concave border of each kidney is the renal _____.

If red blood cells and proteins are detected in urine, it may indicate that a. the filtration membrane in the glomerulus is not functioning properly. b. the microvilli of the proximal convoluted tubules are not reabsorbing properly. c. the collecting ducts are not secreting properly. d. parietal cells are not responding to antidiuretic hormone.

Which of the following structures would not be located entering/exiting the renal hilum?

Which structure(s) is/are made of skeletal muscle?

Trace the route of an oxygenated red blood cell from the time it passes into the kidney in a renal artery until it enters a venule as a deoxygenated red blood cell by placing the following vessels in their correct order: 1) segmental artery 2) arcuate artery 3) interlobar artery 4) peritubular capillary 5) afferent arteriole 6) peritubular venule 7) efferent arteriole 8) cortical radiate artery 9) glomerular capillaries

The filtration membrane consists of the glomerular capillaries and the podocytes that surround the glomerulus.

The process of tubular reabsorption rids the body of some materials such as hydrogen ions and ammonium ions and some drugs such as penicillin.

Which sequence accurately describes the correct path of fluid flowing through the nephron?

The portion of the renal cortex that extends between the renal pyramids are the

The kidneys produce two hormones: calcitrol and calcitonin.

___are modified simple squamous cells that have pedicels and form the visceral layer of the glomerular capsule.

The first branch of the renal artery is the

Principal cells in the distal convoluted tubules contain receptors for antidiuretic hormone and

Which of the following is least likely to affect filtration in the glomerulus?

At the base of each renal pyramid, the interlobar arteries arch between the medulla and cortex to become the _____ arteries.

The movement of substances through the epithelial cells and then into the peritubular capillaries is _____ reabsorption.

All nephron loops (loops of Henle) receive their blood supply from the vasa recta.

What is the structure that is indicated on the diagram?
