Question

(1)Gill capillaries→ oxygenated blood→heart → body cells→ deoxygenated blood→gills

(2)Gill capillaries→ oxygenated blood→ body cells→ deoxygenated blood→ heart→gills

(3)capillaries→ heart →oxygenated blood→ body cells→ deoxygenated blood→heart→gills

(4)Gill capillaries→ oxygenated blood→heart → body cells→ deoxygenated blood→heart→gills

Answer 1

Answer:

option (4)

Explanation:

Fishes have a 2-chambered heart, with an atrium and a ventricle. In fishes, theheart pumps out deoxygenated blood, which is oxygenated by the gills and supplied to the body parts from wheredeoxygenated blood is returned to theheart.

Answer 2

The correct pathway of blood flow in the fish body is from Gill capillaries → Oxygenated blood → body cells → Deoxygenated blood → heart → Gills. (OPTION 2)

CIRCULATORY SYSTEM IN FISHES -

• Fishes have a single circulatory system for blood circulation in the blood.
• They consist of a two-chambered heart with a single atrium and ventricle.
• Fishes show gill circulation and systemic circulatory for blood circulation.
• Deoxygenated blood from the body cells is collected in the atrium and passed to the ventricle.
• From the ventricle, blood is pumped to the gill for re-oxygenation.
• After re-oxygenation in gills, the oxygenated blood is transported to different body organs.
• The blood is then returned back to the heart showing a unidirectional blood flow.
