Answer #1

The average human adult has more than 5 liters (6 quarts) of blood in his or her body. Blood carries oxygen and nutrients to living cells and takes away their waste products. It also delivers immune cells to fight infections and contains platelets that can form a plug in a damaged blood vessel to prevent blood loss.

- Red blood cells transport oxygen

- White blood cells are part of the immune response

- Neutrophils digest bacteria

- Monocytes become macrophages

- Lymphocytes consist of B cells and T cells

- Platelets help blood to clot

- Red blood cell count detects anemia

- Hematocrit is the percentage of RBCs in relation to the total volume of blood

- The number of WBCs increases in infection and tumors

- The number of platelets indicates whether bleeding or clotting is likely

- Hemoglobin binds oxygen

Enviromental Biochemistry Recent studies indicate that relatively low concentrations of Cd in cells of the proximal tubule lining can interfere with their attachment to each other. This attachment/adhesion is caused by “adherins” (external proteins) binding to catenins on and in neighboring cells to bring the cells together. Disrupting adherin-catenin connections, and a change in the localization of Na+/K+ATPase in the membranes, seem to be the earliest changes scientists have identified that coincide with reduced function of the proximal tubules in...

Cells of the pancreas (an organ located in the abdomen that is part of the digestive system) determine the set point for blood glucose (blood sugar). After a meal, glucose levels are elevated and the pancreas detects the change and produces insulin. Insulin and glucose move into the bloodstream where they are transported to different areas of the body. The insulin allows glucose to move from the bloodstream into the muscles and liver where the glucose is stored or used...
