White and red blood cells.
The two major pathways of the vascular system are the systemic circulation, which carries oxygenated blood from the heart to the body's tissues and organs, and the pulmonary circulation, which carries deoxygenated blood from the heart to the lungs for oxygenation.
Food and oxygen.
The organs of the circulatory system include the blood, blood vessels, and heart. The blood is an unusual organ in that it is a liquid.
The pulmonary vein and the aorta: a) The pulmonary carries oxygenated blood from the lungs to the heart. b) The aorta carries the oxygenated blood from the heart to the body and head.
There are two circuits: Pulmonary-carries blood to the lungs and back to the heart Systemic-carries blood from the body and back to the heart
The two blood circuits of the body are the systemic circulation, which carries oxygen-rich blood from the heart to the body tissues and back to the heart, and the pulmonary circulation, which carries oxygen-poor blood from the heart to the lungs for oxygenation and back to the heart.
Oxygen, glucose, various protiens, enzymes, vits, minerals are all carried to all cells in the body by blood.
Blood is not "converted" into urine. Urine is EXTRACTED from the blood by the two organs called the "kidneys".
There are open circulatory systems and there are closed circulatory systems. In the open systems found in insects and invertebrates the fluid which carries the blood does not remain within any vessels but rather it bathes the cells of the organs thus transfering the nutrients. In a closed system the blood remains within blood vessels like in the case with humans and the nutrients are diffused out of these vessels to the cells of the organs.
Blood carries nutrients e.g. glucose and oxygen to cells
The lungs and the kidneys are two organs that respond to changes in blood buffer equilibrium. The lungs regulate carbon dioxide levels by adjusting breathing rate, while the kidneys control bicarbonate levels through filtration and reabsorption. Together, they help maintain the blood's pH balance.
Blood vessels are the tubes that carry blood. Blood vessels include arteries, veins, and capillaries.
