This project looked at how carbohydrates can have an effect on the ability of proteins to cross the blood-brain barrier (BBB). The blood brain barrier are formed by endothelial cells of the brain capillaries, restricts access to brain cells of blood-borne compounds and facilitates nutrients essential for normal metabolism to reach brain cells. This is a very tight regulation that results in the inability of small and large therapeutic compounds to cross the BBB. Lipidic systems can be…

It transports air between the lungs and the body’s exterior the nose, pharynx, mouth, larynx, trachea, bronchi, and bronchioles. Nose and Nasal Cavity Structure: The nose and nasal cavity is line with cilia and capillaries. It secrets mucus, filters debris out in the air and warms the air to 37 degree centigrade. The nose is the face structure comprising of cartilage, bone, muscle, and skin that supports and protects the anterior portion of the nasal cavity; whilst the nasal cavity is the…

approximately five minutes while being mixed occasionally. After time was up 3 mL of “with mustard” was drawn into the first syringe. Then the syringe was inverted and 1 mL of air was drawn. A pipet was then placed in a beaker with DI water and due to capillary action a small amount was drawn in and then the pipette was inverted. The water droplet slowly moved to the pointed end of the pipet and placed securely on the syringe with the free tubing. The respirometer was placed on test tube rack.…

Bio 2.3 Ecological niche Three species that I studied 1.)Dolphin 2.)Great White Shark 3.)Emperor Penguin Animals need gas exchange for one main reason and that is to survive , all organisms need this gas exchange process to burn glucose for fuel which is a simple but important energy source that is a component of many carbohydrates. The respiratory system is where there is a series of organs taking in oxygen and getting rid of carbon…

In the closed circulatory system, blood never leaves the arteries, capillaries, and veins. This system is pressurized and needs multiple arteries and veins. Evolutionists believe that once an animal could no longer diffuse its water and nutrients, it evolved to an open circulatory system, then it evolved to the superior closed…

Elizabeth Barron Winters OA May 10, 2017 Case study A case of Diabetes Insipidus The body regulates by balancing fluid intake and removing extra fluid. Excessive thirst is polydipsia were an adult consumes more than 4 quarts of any beverage per day. Excessive urination is considered polyuria were an adult urinates 50 ml/kg or more in body weight per two hours. Central is the damage of the persons hypothalamus or pituitary meaning the kidneys are removing to much fluid from the body…

Venous return is the flow of blood back to the heart. This process is achieved by five mechanisms. The Pressure Gradient, now this mechanisms work via the heart generating pressure even though the pressure is weaker in the veins than in the arteries it is still the most important force in the venous flow. Gravity, but only when you are sitting or standing anywhere above the heart simple gravity is at work in returning blood back to the heart, not to say that very thing isn’t still working…

Name of Activity: Metamorphosis Resources: - The Very Hungry Caterpillar – Belk Library - Pipe cleaners, paper plates, popsicle sticks, and craft pom-poms – Hobby Lobby - Crayons, color pencils, and glue- Freedom Trail Objectives: My objective is to teach kids about metamorphosis by using the popular children’s book The Very Hungry Caterpillar. Then I’ll have them create either caterpillars using popsicle sticks and pom-poms or decorate butterfly wings using crayons and color pencils. Hook:…

amount of bioavailable free testosterone. Older men typically have lower levels of free testosterone, and sex hormone-binding globulin (SHBG) levels increase. SHBG is not bioavailable as the proteins bound to the testosterone cannot exit through the capillaries. Thus free testosterone is required. Bioavailable testosterone is important for fertility, and for both cardiovascular health and sex health. Testosterone levels generally decrease with age at the rate of 0.4-2% annually. Humans consume…

Cardiovascular Responses and Adaptions The function of the cardiovascular system is to provide the body with oxygen and nutrient and to remove carbon dioxide from the body and metabolic waste. The cardiovascular system responds to the increase in exercise. The cardiovascular responses that should have occurred after 8 weeks of exercise, would include, an increase in size of the left ventricle, increase in stroke volume, increased cardiac output, increase in contractility, and an increase in…
