P4 – Explain the role of the kidney in the homeostatic control of fluid balance Homeostasis is how our body works to keep the internal environment constant. The kidneys play a role in the control of fluid balance. For this assignment I will be discussing the gross anatomy of the renal system and the kidney. Renal System The renal system is a group of organs that work together to produce‚ store‚ and release urine. It consists of 2 kidneys‚ ureters‚ the urinary bladder‚ urethra and renal vessels which

the net movement is from a region of higher concentration to a region of lower concentration. Osmosis is of prime importance in living organisms‚ where it influences the distribution of nutrients and the release of metabolic waste products such as urea. Many nutrients and essential molecules that one needs to live are dissolved in water. So if water couldn’t diffuse‚ we wouldn’t get essential molecules to live. If blood cells‚ for example‚ are placed in contact with an isotonic solution‚ they

The cells in the solutions of distilled water‚ 0.4% NaCl‚ and 0.9% NaCl would all appear to be inflated and could burst. This is due to the fact that the solution is hypotonic to the potato‚ thus water is entering the cell. Meanwhile‚ the cells in the solutions

preventing the passage of ions and other solutes. Also known as water channels‚ aquaporins are integral membrane pore proteins. Some of them‚ known as aquaglyceroporins‚ also transport other small uncharged solutes‚ such as glycerol‚ CO2‚ ammonia and urea across the membrane‚ depending on the size of the pore. For example‚ the aquaporin 3 channel has a pore width of 8-10 Ångströms and allows the passage of hydrophilic molecules ranging between 150-200 Da. However‚ the water pores are completely impermeable

What a Dermatologist can do for my Dry Skin Dry skin is a common condition that nearly everyone‚ regardless of age‚ has experienced at some time. Dry skin develops from the loss of natural body oils and water in the cells on the top‚ outer layer of your skin. The results can be itchy‚ cracked‚ chapped‚ scaly‚ or red‚ bleeding skin.
