How Does Oxygen Travel Through The Body
How do hormones travel through the body? Do they enter the blood stream via capillary, travel through the lymphatic system, etc.?
Sugar and Alcohol: The stomach does not absorb most nutrients. The stomach has acid and churns the food. Alcohol and sugar can be directly absorbed into the stomach (amylase from saliva helps). Most nutrients are absorbed with enzymes and bile that comes from the pancreas and liver. These nutrients are absorbed in the intestines. ...Read more
Red blood cells: Your red blood cells carry oxygen to your body. Red blood cells are packed with an iron containing protein called hemoglobin that can bind oxygen in your lungs and carry it to every cell in your body. In the tissues, oxygen leaves hemoglobin in part because of the acidic environment, called the Bohr effect, and carbon dioxide is bound by hemoglobin to carry to the lungs where you breathe it out ...Read more
OXYGEN for ENERGY: Biochemically, oxygen (o2) is required for energy production for every living cell. Oxygen is transported by the blood bound to hemoglobin (red pigment in red cells). Oxygen is then delivered to the cells via simple diffusion. Oxygen is taken up by the mitochondria of the cells where oxidation and phosporylation are coupled to make atp (energy molecule). Oxygen converted to h20 in process. ...Read moreSee 1 more doctor answer

Sweating: At least two mechanisms. The body first reacts by dilating (enlarging the diameter) of the vessels near the skin surface, thus allowing for more surface area heat exchange to occur. Sweating is additive to this process, cooling the skin by evaporation. Together, these processes help to prevent overheating. Normally, we sweat as much as a liter throughout the entire day. ...Read more
O2: Affects the body by increasing the delivery of o2 to the tissues that need it. This is only effective when there is o2 deprivation state as in hypoxemia of many causes or sepsis or in some poisoning to reverse the occupation of the poison on the hemoglobin so o2 can be carried and delivered. It can kill anaerobic bacteria. In other cases, it is all without proof of need. O2 is kreb's cycle. ...Read more
Via hemoglobin: within red blood cells. It happens continuously as blood circulates. ...Read more
Food route: chew in mouth, stomach mixes and meters out into duodenum and then into small intestine for absorption. The residual makes it into the right part of the colon within an hour or less in most people. then over the next 1-4 days it slowly moves toward the rectum where it is slowly dehydrated (no digestion takes place in the colon, except bacterial degradation), eventually expelled ...Read more
Here are some...: Assumed leaving for others' body, that is, vagina, some able sperms in semen, after liquefying, may swim upstream through cervical canal, uterine cavity to Fallopian tube of fertilization. If leaving but to "wrong" sites like mouth, rectum, or to the air wilderness, these sperms under such fate will die, decay, & disappear like any biological being. ...Read more

Swallowing the air during the act of eating or chewing 3. Inserting gas into body there is no adverse effects as long as it passes naturally most people pass flatus approximately 14 x a day. ...Read more
Keeps it Acid: The stomach cells keep producing hydrochloric acid (hcl) to keep the ph about 2-3. When you eat food, the vagus nerve triggers the stomach cells to secrete more acid. Some medications break down the normal protective barrier (aspirin, tobacco, steroids). When ulcers form, then doctors sometimes use other medicine to cut down on acid production to allow the ulcer to heal. ...Read more
Well...: Studies have been done with people apparently awake 8-10 days but there is evidence of micro-sleeping where there are transient periods of reduced responsiveness and consciousness during that time. The record is apparently 11 days. It is not good for mental and physical health so not recommended to try ...Read moreSee 2 more doctor answers
