Answer:
1-) Patent ductus arteriosus: this duct normally must be closed two days after the baby is born, but if not, it will carry oxygenated blood to the pulmonary artery producing a mixture with oxygen-poor blood and producing a cardiac overload due to the large amount of blood that would reach the right heart.
2-) Transposition of the great vessels: In this defect, the oxygenated blood is collected throughout the body and taken directly to the right heart which returns to the poorly connected aorta (right ventricle) back to the body without oxygenation; on the other hand, the oxygenated blood returns to the left heart, then goes to the pulmonary artery (connected to the left ventricle) and back to the lungs.
3-) Tetralogy of fallot: It is a congenital anomaly that can present different defects at the level of the heart, such as:
- intraventricular communication, in which blood would go from the left heart to the right heart.
- Pulmonary obstruction, there is obstruction of the blood outlet by plugging the duct, which causes a decrease in blood flow to the body.
- Dextraposition of the aorta: The aorta is more deviated to the right and in union with the intraventricular (IVC) communication. Increased amount of bleeding to the pulmonary artery. Bad oxygenation of the blood due to the mixture thereof.
Answer:
Gametic cells.
4 cells.
Chromosomes number reduces to half.
Explanation:
Meiosis may be defined as a type of cell division in which a single parent cell divides to form the daughter cells. The sex cells or gametes (sperm and ova ) undergoes the meiosis division.
The single parent call divides into four daughter cells by the process of meiosis- I and meiosis- II. Meiosis II is similar to the process of mitosis.
Meiosis is also known as reduction division. The chromosome number reduces to half as compared with the parent cell. The haploid cells are produced in the meiosis.
Answer: For an infant, use the 2-finger chest compression technique while only one rescuer is present. Once the second rescuer returns, us the 2 thumb-encircling hands technique. For a child, use one or two hands, whatever is needed to provide adequate compression depth.
Explanation:
Bal stands for Bronchoalveolar lavage. Bal is a process in which a bronchoscope is passed through the mouth and then into the lungs. Fluid is squirted into a part of he lung and collected for examination. Lung diseases can be found from the process of bal.
