explain how deoxygenated blood travel from body to lungs for purification draw a well labelled diagram in support of your answer
Answers
Answer:
The deoxygenated blood is collected from the body tissues through the veins which further combine to form vena cava. This vena cava pours deoxygenated blood collected from the body tissues into the right auricle of heart. From right auricle it goes to right ventricle and from here the blood is pumped into the pulmonary artery which takes the deoxygenated blood from heart to the lungs. In the alveoli of lungs the blood is oxygenated. This oxygenated blood is pumped into the pulmonary veins which pours the blood into the left auricle. From here the oxygenated blood is poured into the left ventricle. The left ventricle pushes the blood into the aorta which pumps the oxygenated blood into the body tissues and supply oxygen through the tissues for various body functions.
Answer:
Deoxygenated blood reaches the heart via the superior and inferior vena cava.
Explanation:
- A second circulatory system exists in humans. This implies that the heart receives blood twice.
- Systemic circulation and pulmonary circulation are the two types of blood flow in the human body.
- The flow of blood between the hearts and bodily organs is known as systemic circulation. The sole circulation in the lungs is called the pulmonary circulation.
- Through the vena cava, deoxygenated blood reaches the heart before travelling through the pulmonary artery to the lungs. The lung cleans the blood, converting it from deoxygenated to oxygenated blood.
- The pulmonary vein carries the oxygenated blood from the lung to the left atrium. The left atrium serves as the continuation of the circulatory system.
