What is the order of the blood vessel types that a red blood cell would pass through as the blood leaves the heart, travels to a tissue, and then returns to the heart

The order of blood vessel types as red blood cells leave the heart is via the pulmonary artery then it flows to the lungs( a tissue) there it reacts with oxygen molecules which converts it to oxygenated blood that is transported to the heart via the pulmonary vein. Therefore the order is:

Heart - to- Pulmonary artery- to- Lungs (Tissue)- to- Pulmonary vein -to- Heart

Explanation:

The order of blood vessel types as red blood cells leave the heart is via the pulmonary artery then it flows to the lungs( a tissue) there it reacts with oxygen molecules which converts it to oxygenated blood that is transported to the heart via the pulmonary vein. Therefore the order is:

Heart - to- Pulmonary artery- to- Lungs (Tissue)- to- Pulmonary vein -to- Heart

the energy generated by an individual's metabolism is calculated in met (metabolic equivalent of task). the met is the ratio of the work metabolic rate to the resting metabolic rate. one met is illustrated as 1 kcal per kilogram per hour, and is probably equal to the energy cost of sitting quietly.

1 met is equal to 1.162 watt per kg

1 kg is equal to 1000 grams

as the person weighs 80000 gm, that is, 80 kg.

therefore, 80*1.162 = 92.96

thus, the person expends 92.96 watts of power while at rest.
