Question

Match the definition to the correct term in the given list.
A thin-walled blood vessel that carries blood from capillaries to the heart.
Vein, Cardiac cycle, Cardiac output, Heart rate, Heartbeat, Double circulation, Circulatory system, Extracellular fluid, Intercellular fluid, Myogenic heart, Neurogenic heart.

Answer 1

Hint: In a circulatory system, the heart pumps blood and purifies the blood however the transportation of blood throughout the body is carried out by the blood vessels. There are different systems of circulation also available such as the portal system.

Complete answer:-Definition of a Vein:
A vein is defined as the blood vessel that carries blood from all the organs to the heart.

-Definition of the Cardiac cycle:
The cardiac cycle can be defined as all the processes that occur from the starting of a heartbeat to its end.
-Definition of the Cardiac output:
The cardiac output is the amount of blood pumped by the heart in 1 minute.
-Definition of the Heart rate:
The heart rate is defined as the speed at which the heartbeats.
-Definition of the Heartbeat:
The heartbeat is defined as the pulsation of the heart which consists of one systole and one diastole.
-Definition of the Double circulation:
The double circulation is defined as the process in which the blood passes through the heart twice, in a single cardiac cycle only.
-Definition of the Circulatory system:
The circulatory system is defined as the system that circulates the blood and lymph throughout the body. This is done with the help of the heart, blood vessels, blood, lymph, and lymphatic organs.

-Definition of the Extracellular fluid:
The extracellular fluid is defined as all the fluid that is present outside the cell in the body of a multicellular organism.

-Definition of the Intercellular fluid:
The intercellular fluid is defined as all the fluid that is present inside the plasma membrane of the cell of an organism.

-Definition of the Myogenic heart:
The myogenic heart is defined as a heart in which the heartbeats originate from the muscular tissue present within the heart itself.

-Definition of the Neurogenic heart:
The neurogenic heart is defined as a heart in which the heartbeats originate from the neurons and brain. The example is the heart of the non-chordates.
Thus, the given definition matches the definition of a vein.
Hence, the correct answer is a Vein.

Note: The vein is defined as the blood vessel that carries the oxygenated blood and the artery is defined as the blood vessel that carries the deoxygenated blood. However, this is completely wrong. This is because the pulmonary artery carries deoxygenated blood and the pulmonary vein carries the oxygenated blood.
