___________ is when all essential nutrients are given directly into the blood stream.
17 Learning Objective: LO 3.6 Discuss how glucose, fatty acids, and amino acids are used by the cells to provide energy. Section Reference: Section 3.6 Metabolism of Nutrients: An Overview 49) The chemical breakdown of glucose to produce energy is an example of: a) catabolism. Neurons obtain virtually all of their nutrition via aerobic metabolism of glucose. Since this process requires large amounts of oxygen, the nervous system requires a high blood flow, typically around 50cc/100grams of tissue/minute. Plasma is the liquid portion of your blood that transports water and nutrients to your body’s tissues. Red blood cells are disc-shaped cells containing hemoglobin, which enables the cells to pick up and deliver oxygen to all parts of the body, then pick up carbon dioxide and remove it from tissues. Blood is the red fluid that circulates in our blood vessels, i.e.veins and arteries. The main function of blood is to act as the body’s transport system, but it also has a major role in the body’s defense against infection. There is no substitute for blood. It cannot be made or manufactured. Section Reference: Section 3.4 Digestion and Health 42) During ________________, the digestive system can absorb whole intact proteins. a) infancy b) aging adulthood c) adulthood d) childhood Answer: a Difficulty: Medium. Your blood is the fluid that delivers oxygen and nutrients to your cells. The blood is essentially a water-based mixture of many different chemicals, including a suspension of cells. Specifically, plasma is the liquid portion of blood. Your blood is a fluid that connects all body cells. Blood Components. Your blood is a fluid that connects all body cells. Not only does it bring nutrients and oxygen to the cells from the lungs and digestive tract, it carries waste products away from the cells for disposal. Your cells communicate with one another via the blood -- the liquid medium carries chemical messengers from one cell to another. Section Reference: Section 3.4 Digestion and Health 41) ___________ is when all essential nutrients are given directly into the blood stream. a) Enteral feeding b) Tube feeding c) Total parenteral nutrition d) Force feeding Answer: c Difficulty: Easy Learning Objective: LO 3.4 Describe how certain stages of life affect the type of foods that can be ... There are regions of the brain that lack a blood-brain barrier. These are in brain regions that are responsible for sensing the internal melieu of the body (such as serum osmolarity) or in areas that are involved in either sensing hormone levels or releasing hormonal factors into the blood stream. Chapter 12 - The Nutrition of the Brain. Circulation of the brain. There are four arteries supplying the brain (figure 35). The two carotid arteries and their branches comprise the anterior circulation and the two vertebral arteries comprise the posterior circulation. There are small penetrating blood vessels that come off the larger vessels.
Total parenteral nutrition.
