cannot pass through the blood vessels. The reaction occurs from the complement system when the person receiving the blood has a rare protein on their blood cells. So antibodies to this certain antigen are not present until after the patient is exposed to the blood. This is why all blood is typed‚ crossed‚ and then cross-matched with the potential recipients’ blood. 4. Our lymphatic systems have several jobs‚ from body tissues it removes extra fluids‚ it produces immune cells‚ it helps in the absorption

Purpose: The purpose of this lab is to test the effects of osmosis on eggs in hypertonic solutions and hypotonic solutions. Hypothesis: If the corn syrup is a hypertonic solution‚ then the egg’s size will shrink. If the water is a hypotonic solution‚ then the egg will swell. Materials: Styrofoam cups (2 per group) Styrofoam cups to weigh down egg (2) Balance Paper towels Vinegar (enough to cover egg) Distilled water Corn syrup Fresh eggs (2 per group) Procedure: Day

How do they interact to cause a transfusion reaction? * An antigen is a molecule that sometimes stimulates an immune response. An antibody is a blood protein produced in response to and counteracting a specific antigen. Antigens are what causes a person to need a transfusion because their body is resisting their own blood.

and off to the sides. The locations of these two organs affect interactions between the frogs’s respiratory and circulatory systems because a frog’s heart needs oxygen which is required from the lungs therefore the circulatory system which is the blood and the heart needs oxygen from the respiratory system which is the lungs. Since they are so close together‚ both systems have easy access to one another. 2. Describe how the frog’s circulatory and digestive systems are physically connected. The

FORMATION OF BLOOD CLOTS Definition • A blood clot is a mass of blood cells and blood components that form to stop the bleeding that occurs when a blood vessel is injured. When a blood vessel is broken‚ platelets in the blood become sticky and clump together at the site of the injury. They begin to form a mass to stop the flow of blood. Description • Clotting is the body’s normal response to a bleeding injury. It is a necessary function to prevent a person from losing too much blood. Most

Julia Babin Ms. Bukola 11/6/2012 Bio Lab W 8 Cell Structure and Function Prokaryotic cells do not contain a nucleus. Eukaryotic cells do contain a nucleus. Organisms are eukaryotic except Bacteria and Achaea. Organelles are small membranous bodies‚ each with a specific structure and function. Prokaryotes do have cytoplasm‚ which is the material bounded by a plasma membrane and cell wall. This contains ribosomes‚ small granules that coordinate the synthesis of proteins

Epidemiology‚ blood donors are 88% less likely to suffer a heart attack and 33% less likely to suffer any type of cardiovascular event. Why is that? Well‚ researchers aren’t 100% sure‚ but believe it may be due to either one of two things. The first theory is that blood donors must be considered “healthy” before they roll up their sleeve‚ so they are less likely to suffer heart disease because they are already in good health and probably have lower blood pressure and cholesterol levels that non-blood donors
