Question

1. Mention any two components of blood.
2. Trace the movement of oxygenated blood in the body.
3. What is the function of valves present in between atria and ventricles.
4. Write one structural difference between the composition of the artery and veins.

Answer 1

Hint: Heart and the blood this is the part of the circulatory system, where blood is the fluid connective tissue component that consists of several types of cells, which have there own function, and blood is also important for the carry of oxygen to the body parts, and heart is the muscular organ which is an important part of the body that always pumps the blood that comes from the body parts and the lungs.

Complete answer:
1) When coming to the components of the blood, it is made up of liquid and solid components, where the liquid component of the blood is called plasma, and the solid portion includes the various types of cells, such as Red blood cells, white blood cells, platelets.
2) When deoxygenated blood carried to the right auricles and the right ventricles it carried to the lungs by the pulmonary arteries, wherein the lungs blood gets oxygenated and then move to the left auricles through the pulmonary veins, and from the auricles, they move to ventricles and from the left ventricles to the body parts through the systemic aorta.
3) The valves present between the right atrium and the right ventricle are called tricuspid valves, and the valves present between the left atrium and left ventricles are mitral valves and they combined called atrioventricular valves, the main purpose of them is to prevent the backflow of the blood.
4) Arteries and the veins are the blood vessels where arteries are thick-walled and cylindrical and they carry oxygenated blood, and the veins are thinly walled and collapsed in look and they carry deoxygenated blood.

Note: As we know arteries carry oxygenated blood and veins carry deoxygenated blood, but there are some exceptions where the pulmonary artery carries deoxygenated blood from the heart to lungs, and the pulmonary vein carries oxygenated blood.
