Explanation Reason for the correct statement: The cardiovascular system of the fish consists of the exchange of the gases in the network of the blood capillaries in the form a single circuit and the cardiovascular system of the humans consist of two circuits namely the systemic and pulmonary system. Option (b) is given as “Your circulation has two circuits; fish circulation has one”. As “there is a single circuit in the fish due to the exchange of the gases and there are two circuits in the humans, namely the systemic and pulmonary system, which accounts for the main difference between the cardiovascular system of the fish and humans”, so it is the right answer. Hence, option (b) is correct. Reasons for the incorrect statements: Option (a) is given as “Your heart has two chambers; a fish heart has four”...

Summary Introduction

Introduction:

The cardiovascular system of a fish performs the exchange of gases between the surface of the fish and the body cells through the network of blood capillaries. The cardiovascular systems of the humans consist of the pulmonary system and systemic system. The blood flows inside the blood vessels and reaches the organs. Therefore, there are two circuits in humans and one circuit in fish.

Blood enters the atrium and pumped into ventricle. B. Blood pressure alternates between systolic and diastolic at all times. C. Atrium provide 1 pump, ventricle provides 2nd pump. D. Heart pumps blood simultaneously in systemic and pulmonary circuit.

The difference between the amphibian and mammal hearts is thata. in the amphibian heart, oxygenated and deoxygenated blood mix completely in the single ventricle.b. in the amphibian heart, there are two SA nodes so that contractions occur simultaneously throughout the heart.c. in the ventricle in the amphibian heart, internal channels reduce mixing of blood.d. in the amphibian heart, only the left aorta pumps oxygen obtained by diffusion through the skin
