Glomerular filtrate rate: pressures that affect GFR, NFP & GFR and blood composition

By: HWC, Views: 8202

• The glomerular filtration rate is the amount of filtrate formed per minute within the renal corpuscle. • Once the filtrate is formed it moves down the tubule. • The production and movement of filtrate depends on three pressures: I. Glomerular blood hydrostatic pressure (GBHP) is ...

Caring for Your Retainer Retainers, just like your teeth collect plaque, bacteria and food particles. You should clean your retainer everyday! Keep your retainer soaking when it is not in your mouth. Use a mouthwash rinse to freshen it up and keep it free of bacteria. Keep your retainer away fr...

Covalent bonds - role in the body

By: HWC, Views: 7707

A covalent bond is formed when atoms share one or more pairs of electrons. This is opposed to an ionic bond, where electrons are actually transferred from one atom to another. Formation • Atoms fill up the outer orbital by sharing electrons. • Two oxygen atoms sharing electrons form on...

Lipid absorption - end products & transport mechanism

By: HWC, Views: 7259

• The end products, fatty acids and monoglycerides, depend on bile salts for absorption. • Bile salts form micelles (tiny spheres), which ferry fatty acids and monoglycerides to epithelial cells. • Free fatty acids, monoglycerides, and some phospholipids and cholesterol molecules, dif...

Alternative Energy Sources

Points at which organic compounds enter the reaction stages of aerobic respiration. Complex carbohydrates are broken down into simple sugars, such as glucose. They become the substrates for glycolysis. If your body doesn't need to burn glucose for energy, glucose-6-phosphate can be co...

Properties of water -structure of water and polarity (Ionized and polar compounds)

By: HWC, Views: 7857

■ Water transports most of the molecules in the body. ■ The structure of a water molecule allows it to dissolve other molecules. ■ Shared electrons spend more time near the oxygen atom. ■ Oxygen end has a partial negative charge. ■ Hydrogen ends have a partial positive charge....

New DNA Strand Replication

By: HWC, Views: 7124

First step: strands are separated • Helicase unwinds the DNA double helix at the replication fork • SSBs coat the single strands to prevent reannealing • Polymerase attaches nucleotide at 3' end • Synthesis is in 5' to 3' direction DNA Polymerase: • Only extends nucleic ac...

Glomerubular filtrate rate -pressures that affect GFR and net filtration pressure

By: HWC, Views: 8177

• The glomerular filtration rate is the amount of filtrate formed per minute within the renal corpuscle. • Once the filtrate is formed it moves down the tubule. • The production and movement of filtrate depends on three pressures: I. Glomerular blood hydrostatic pressure (GBHP) is pre...

Protein digestion - stomach & small intestine

By: HWC, Views: 7196

• Protein digestion occurs in the stomach and small intestine. • The stomach enzyme pepsin initiates the process. • Pancreatic and intestinal brush border enzymes complete the digestive process. • In the stomach, pepsin is created from pepsinogen in the presence of pH-lowering hyd...
