Our blood carries oxygenated blood from the chambers of the heart, delivers it to cells in return for deoxygenated blood. It then takes this deoxygenated blood to the lungs, where it’s finally excreted with the help of the respiratory system. However, that’s not the only purpose...
How is cardiac output affected by an increase in exercise intensity? How does blood get oxygenated? What are the steps unoxygenated blood takes through the heart, to the lungs, and back to the body as oxygenated? How does deoxygenated blood enter the heart? What structures must it pass throu...

13 Recently, we found functional near-infrared spectroscopy as a useful, non-invasive imaging tool to detect levels of oxygenated and deoxygenated hemes during local muscular and brain activity during acupuncture stimulation.14 More recently, neuroimaging techniques (e.g., positron emission tomography,...
The researchers used functional Near-infrared Spectroscopy (fNIRS), a non-invasive optical imaging technique to measure the brain signals based on the level of oxygenated and deoxygenated blood in the brain. Prior to the experiment, couples answered a questionnaire that aims to measure how often the...
Fresh, oxygenated blood flows through your arteries to the different parts of your body, and your veins work to send deoxygenated blood back to the heart to start the cycle all over again. What Happens When It Breaks: Without a healthy heart, your entire body is at risk of ...
Which of the following statements about the hepatic portal system is false A. Its tributaries lack valves B. It begins in capillaries and ends in hepatics sinusoids C. It usually drains only the alimentary c D. It carries deoxygenated blood E. It has clinically important anatom...

How does blood become deoxygenated? How does each body system contribute to the homeostatic balance of the cardiovascular system? How does blood carry oxygen? Explain how organ systems work together to maintain normal body functioning. Give a detailed explanation of how the muscular system works. ...
