explain the mechanism of transportation in humans
Answers
Explanation:
The human heart is a muscular organ, which has four chambers. The two upper chambers called the right atrium and the left atrium, and the two lower chambers called the right ventricle and left ventricle. The right atrium and the right ventricle together may be called the right heart. The left atrium with the left ventricle together can be called as the left heart. All the chambers of the heart are separated by muscular walls called septum.
Blood Vessels
Arteries and veins are the main blood vessels. These are interconnected by a network of smaller vessels called capillaries. Veins carry deoxygenated blood to the right side of the heart whereas arteries carry oxygenated blood away from the heart to different parts of the body.
blood is the mechanism of transportation
Blood is a specialized body fluid. It has four main components: plasma, red blood cells, white blood cells, and platelets. Blood has many different functions, including:
transporting oxygen and nutrients to the lungs and tissues
forming blood clots to prevent excess blood loss
carrying cells and antibodies that fight infection
bringing waste products to the kidneys and liver, which filter and clean the blood
regulating body temperature
The blood that runs through the veins, arteries, and capillaries is known as whole blood, a mixture of about 55 percent plasma and 45 percent blood cells. About 7 to 8 percent of your total body weight is blood. An average-sized man has about 12 pints of blood in his body, and an average-sized woman has about nine pints.
