Summary Introduction
Blood vessels are an important part of the circulatory system. The blood continuously flows through the blood vessels. Blood vessels are categorized into three major types namely arteries, veins, and capillaries. Capillaries link the arteries and veins.

That afternoon you rent a car and drive up to the trailhead at 2,438 m. You hike up to your first camp at 2,745 m. The next day you hike up to 3,048 m. You begin to have a severe headache and feel nauseous and weak. If your condition worsens, you may begin to have difficulty hiking. What causes altitude sickness? The concentration of oxygen at sea level is about 21% and the barometric pressure averages 760 mmHg. As altitude increases, the concentration remains the same but the number of oxygen molecules per breath is reduced. At 3,658 m the barometric pressure is only 483 mmHg, so there are roughly 40% fewer oxygen molecules per breath.

Capillaries are the site where blood mixes with interstitial fluid to allow for gas and nutrient exchange.arrow_forward
