A research on the circulatory system

Most birds live and fly at relatively low altitudes, but some species live, migrate, or are occasionally found at higher altitudes Source: The transport of O2 occurs along several steps of a cascading physiological pathway from atmospheric air to the mitochondria in tissue cells e. The effectiveness of this pathway at transporting O2 during hypoxia is imperative for flight at high altitudes, which depends upon several distinctive characteristics of birds in general and many unique features that have evolved in high flyers. The properties of O2 utilization and ATP turnover in the flight muscle are also important to consider in high fliers Source:

Arteries carry oxygen-rich blood away from your heart. Veins carry oxygen-poor blood back to your heart.

Your blood leaves the left side of the heart and is pumped out to the rest of your body. The main artery from your heart is called the aorta.

As your blood travels throughout your body, it enters smaller and smaller blood vessels, reaching every cell, dropping off nutrients and picking up waste products and carbon dioxide. Your blood then starts the trip back in your veins, entering larger and larger ones as it goes, passing through your kidneys and liver on the way to drop off waste products.

The blood eventually arrives back at the right side of your heart to start the trip all over again. As we age, our arteries tend to thicken, get stiffer, and narrow. This is called arteriosclerosis. A narrowing of the arteries from the build-up of plaque can lead to coronary heart disease, and can cause a heart attack when this occurs in the blood vessels leading to the heart.

Narrowing of the arteries in other places, such as your legs, can cause what is called Peripheral Arterial Diseaseor PAD. PAD can lead to sores, pain with walking, or amputation. When the smaller arteries are affected it is called arteriolosclerosis. It is very important that individuals with specific medical problems or questions consult with their doctor or other health care professional.Atherosclerosis– Literally, “hardening of the fatty stuff.” High fat diets can lead to formation of fatty plaques lining blood vessels.

These fatty areas can become calcified and hard leading to arteriosclerosis, hardening of the arteries. When blood vessels become less Circulatory system diseases Read More. Lympha Press® is a dynamic compression therapy system.

Your vascular system is made up of vessels that carry your blood throughout your body. Arteries carry oxygen-rich blood away from your heart. Veins carry oxygen-poor blood back to your heart. Recent Examples on the Web. As the body temperature increases very rapidly, the central nervous system and circulatory system are impacted. — Katherine Harmon, Scientific American, "How Does a Heat Wave Affect the Human Body?," 23 July This quick workout is designed to build heat in the body and stimulate the circulatory system, which brings more blood flow and oxygen to the muscles. The digestive system is a group of organs working together to convert food into energy and basic nutrients to feed the entire body. Food passes through a long tube inside the body known as the alimentary canal or the gastrointestinal tract (GI tract).
