Question

Starting the heart, organize the path of blood flowing in fish:

a. back to the heart
b. body tissues
c. gills
d. veins
e. arteries

Answer 1

Heart-> Gills -> Arteries--> Body tissues->veins-> back to heart (C,E,B,D,A)

Step-by-step explanation:

Deoxygenated blood is pumped from the heart of fish to the gills. The gaseous exchange occurs at gills. The oxygenated blood is carried to body tissues via arteries. The deoxygenated blood from body tissues is picked via veins and is delivered to the heart. The cycle is repeated in the same manner. This makes the direction of blood flow in fishes as following:

Heart-> Gills -> Arteries--> Body tissues->veins-> back to heart
