Answer: Oxygen attaches to the haemoglobin in your red blood cells. Your red blood cells circulate around your body via arteries and capillaries supplying blood to all of your body cells. Then, veins take the deoxygenated blood back to the heart and from there the pulmonary artery takes it to the lungs for it to become oxygenated once again. The pulmonary vein then takes the blood to the heart once again, and the process repeats itself.
Answer: oxygen (O2) enters the body via respiration (breathing) it enters small pouches in the lungs called alveoli. these alveoli are surrounded by tiny blood vessels called capillaries. there is an exchange at these alveoli, carbon dioxide (CO2) exits the blood and O2 enters the blood. this freshly oxygenated blood is now returned via the pulmonary vein to the Left side of the heart. the left ventricle pumps blood to the body. as the blood vessels get smaller they again form capillaries. there is another exchange of gasses, O2 is transferred out to the cells and CO2 (the waste product from cellular metabolism) is transferred to the blood. the Deoxygenated blood is then returned via the venous system to the right side of the heart. the deoxygenated blood is pumped back to the lungs and the alveoli via the pulmonary artery. and then the whole cycle starts over again.
Answer: There are thousands and thousands of different kinds of cells in the body. If you could be more specific in the type of cells you want, we can better answer your question. A few random ones: Dermatocyte Hepatocyte Erythrocyte Leukocyte Neuron Schwann cell Parietal cell Myocyte
No. A sperm cell and an egg cell released from an ovary contain half the chromosomes as other cells until the sperm enters the egg cell and its chromosomes join that of the egg. At that point the egg cell becomes a new individual with a full complement of chromosomes. In humans a person gets 23 chromosomes from the mother and 23 from the father for a total of 46.
Answer: Erythrocytes (red blood cells) are produced in bone marrow at an average rate between 2.3 to 2.5 million a second, therefore 2.4 x 60= 144 million a minute. Also I hope you searched for this answer to settle an argument with someone who is obviously not as intelligent and awesome as you.... In your face!
