Glucose can cross the cell membrane only using a carrier but in a passive or active way. What is the two significant difference between facilitated diffusion using Glut channel and the cotransport of glucose using Na+ to do it?

Nephritis is a condition in which the kidney becomes inflamed due to an infection, an allergic reaction to medication or an autoimmune response. There are two types of neprhitis:

glomerulonephritis – where the glomeruli become damaged by inflammation, and

tubulointerstitial or interstitial nephritis – where the tubules are damaged by inflammation.

In both cases, normal renal (nephron) function is compromised.

1. First, explain how the nephrons of the kidney normally function to adjust the composition of the blood and produce urine in a healthy kidney. To do this, be sure to do the following:

- Give the main purpose for each part of the nephron
- List the specific substances are being added and removed along the way via either filtration, reabsorption or secretion. Be specific.

3. Using what you know of normal kidney (nephron) function:

a. Which functions of the nephron would be compromised in someone with tubulointerstitial nephritis - filtration, reabsorption or secretion?

b. Below are some complications of tubulointerstitial neprhitis. BRIEFLY (using bullets) define each complication below and BRIEFLY explain why tubulointerstitial neprhitis would cause the following abnormalities/complications:

- Hypokalemia & Hyponatremia
- Polyuria
- Metabolic acidosis

2. Using what you know of normal kidney (nephron) function:

a. Which function of the nephron would be compromised in someone with glomerulonephritis - filtration, reabsorption or secretion?

b. Below are some complications of glomerulonephritis. BRIEFLY (using bullets) define each complication and BRIEFLY(within the bullet) explain why glomerulonephritis would cause the following abnormalities/complications:

- Hematuria * Proteinuria
- Oliguria
- Azotemia

subject. Histology:

1-histological structure of processes involved in the production of mature sperm and ovum?

I wont to answer as histology.

One of the main concepts you will see repeated in this course is: form allows for function (the principle of complementarity of structure and function). Using your textbook or another reliable source, describe the characteristics of a cardiac muscle cell found in the heart and a simple columnar cell found within the small intestine. Contrast these two types of cells in terms of their structure and the organelles found within them. Finally, explain how the structure of each type of cell allows it to perform its function(s).
