Explanation:
The direction of waves of contraction in the heart are very important because they represent the cardiac contraction pathway. It begins from sinoatrial node due to spontaneous depolarization (nodal cells) and triggering of action potentials and transmission of the same to the cardiac cells taking part in the conduction pathway in the cardiac muscle fibers.
The blood flows from the right atrium to the right ventricle via the tricuspid valves when the atrium contracts and ventricles expand. Once the ventricles receive its full amount of blood the tricuspid valves shuts to prevent any backflow of blood into the atrium. When the ventricles contract, blood enter the aorta through the aortic valve.
Iron is an important mineral required by the body to produce the ‘heme’ part of the protein hemoglobin present in the red blood cells of the blood. Oxygen binds with hemoglobin and is carried via blood to various parts of the body. Hence intake of recommended dietary allowance of iron is very important since deficiency can lead to various conditions like anemia.
Polycythemia vera is a condition which leads to increased production of red blood cells. this increases the blood volume and thickens the blood and slows down the blood flow and causes blood clots. The slowness of blood flow and formation of blood clots can lead to heart failure and heart attacks respectively.
Regular exercise and the consumption of a healthy diet can lead to a host of benefits, including increased energy, happiness, health and even a long life. Exercise and diet are pivotal to determining a person’s overall health, and making them both part of your lifestyle can make a dramatic difference in how you look and feel.
If you’re overweight, eating healthfully and exercising regularly can help you lose weight safely and keep it off. If you don’t have a weight problem, physical activity and a healthy diet can help you maintain your current weight and reduce your risk of gaining weight as you age. Healthy foods are generally lower in calories and higher in nutrients than other foods, and regular physical activity burns off extra calories to keep a healthy physique.
Exercise stimulates brain chemicals that help produce feelings of happiness, contentment and relaxation, so you’ll feel better if you workout on a regular basis. Physical activity can also boost your physical appearance as you burn fat and build muscle, which is a significant factor in boosting self-confidence and inspiring a satisfied life.

Answer:
D Phenylketonuria
Explanation:
Infant jaundice is caused by buildup of a compound bilirubin in infant's blood. It leads to yellowing of skin and eyes. There are several risk factors which should be kept in mind. People with east Asian or Mediterranean descent are at more risk of jaundice. Prolonged bruising during labor can lead to breakdown of more red blood cells hence production of more bilirubin again increasing jaundice risk. If mother's blood type is different from the child, the child might receive antibodies from the mother via placenta, hence breakdown of RBCs . Poor breastfeeding can also lead to improper development of baby making it more susceptible to jaundice.
Phenylketonuria is a metabolism error and leads to reduced metabolism of Phenylalanaine. It has got nothing to do with jaundice.
