Question

A female just had a cup of coffee with cream and sugar. You are following the journey of the glucose molecule from ingestion thru cellular respiration which creates H2O and CO2. You will follow the CO2 molecule until exhalation and the H2O to excretion. List the following pathways

Once in the glucose molecule is in the gastrocnemius muscle, cellular respiration occurs and you have CO2 and water that need to exit the body. (BOLD ARE THE QUESTIONS)

C List the pathway from the right gastrocnemius muscle to the point of exhalation.

D. List the pathway the water molecule takes from the right gastrocnemius to the point the water molecule is excreted

Answer 1

C) CO2 is carried to lungs through blood where it is exhaled. The pathway is as follows—

Right gastrocnemius muscle - right medial and lateral sural veins - right popliteal vein - right femoral vein - right external iliac vein - common iliac vein - inferior venacava - right atrium - right ventricle - pulmonary aorta - lungs - CO2 is exhaled here.

D) water molecule is excreted through kidneys and to reach kidneys it takes the following pathway–

Right gastrocnemius muscle - medial and lateral sural vein - right popliteal vein - right femoral vein - right external iliac vein - common iliac vein - inferior venacava - right atrium - right ventricle - pulmonary aorta - lungs - pulmonary vein - left atrium - left ventricle - abdominal aorta - renal artery - kidney - filtered by nephrons - ureter - urinary bladder - urethra - leaves as urine
