This system delivers oxygen and nutrients to all the cells in the body and carbon dioxide and waste to the lungs through blood vessels. Two mains systems in the circulatory system. 1.Pulmonary circulation - sends blood from the heart to the lungs and back. 2.Systemic circulation - sends blood to the rest of the body and back to the heart.
The smallest blood vessels are the capillaries. Most capillaries are so narrow that blood cells pass through them in a single file. Their thin walls (1 cell layer thick) allow oxygen and nutrients to diffuse from blood into tissues and allow carbon dioxide and other waste products to move from tissues into blood.
the chamber that contains deoxygenated blood from the right atrium. Location. Term. pulmonary artery. Definition. artery carrying oxygen-poor blood from the heart to the lungs. Location. veins. The blood vessels that have thin muscle walls and carry deoxygenated blood.

Anemia is a blood disorder affecting red blood cells. Patients suffering with anemia have a decreased oxygen carrying capacity due to a decrease in the number of red blood cells, or a reduced amount of haemoglobin in the blood. There are multiple different types of anemia, some of which are the following: 1. Iron deficient anemiais the most common ...
Leukemia refers to a group of cancers affecting the red bone marrow . Theses cancers cause abnormal white blood cells to multiply uncontrollably, which interferes with normal red blood cell, white blood cell and platelet production. This results in a decrease in oxygen carrying capacity, susceptibility to infection, and abnormal clotting. Leukemia ...
This is a disorder of the thrombocytes, or platelets. It results in a low number of platelets in the blood. Patients with this disorder are prone to excessive bleeding and may experience frequent nose bleeds or bleeding gums, as well as excessive bruising.
This is an inherited blood disorder that causes spontaneous bleeding or bleeding where only minor trauma has occurred. It is caused by deficiencies of different clotting factorsand can vary significantly in severity.
May 15, 2022 · Main Features of the Human Circulatory System. A liquid, blood, to transport nutrients, wastes, oxygen and carbon dioxide, and hormones. Two pumps (in a single heart): one to pump deoxygenated blood to the lungs and the other to pump oxygenated blood to all the other organs and tissues of the body. A system of blood vessels to distribute blood ...

Sep 23, 2021 · The Circulatory System. The circulatory system is a network of vessels—the arteries, veins, and capillaries—and a pump, the heart. In all vertebrate organisms this is a closed-loop system, in which the blood is largely separated from the body’s other extracellular fluid compartment, the interstitial fluid, which is the fluid bathing the ...
