  1. Brachial artery

  2. Vertebel artery

  3. Coronary artery

Choose the correct answer from the alternatives given.
An artery is a vessel that carries:

evs transportation in living organisms circulatory system and organs blood and blood vessels circulatory system blood pressure

  1. blood away from the heart

  2. blood towards the heart

  3. oxygenated blood

  4. deoxygenated blood

Show answer
Correct Option: A
Explanation:
  • An artery is a vessel which is thick walled, carries oxygenated blood (except pulmonary artery) away from the heart.
  • While veins are thin-walled, carry deoxygenated blood (except pulmonary vein) towards the heart.
So, the correct option is 'Blood away from the heart'.

Choose the correct answer from the alternatives given.
Systole refers to the contraction of:

evs transportation in living organisms circulatory system and organs blood and blood vessels circulatory system blood pressure

  1. major arteries

  2. SA node

  3. atria and ventricles

  4. all of these

Show answer
Correct Option: C
Explanation:

The systole is the rhythmic contraction of the chambers of the heart (Atria and Ventricles) and diastole is the rhythmic relaxation of the chambers of the heart. The events occurring during one heartbeat is known as the cardiac cycle. During this cycle, the auricles and the ventricles of the heart rhythmically contract and relax.

So, the correct option is 'Atria and ventricles'.

The only artery which carries deoxygenated blood is the:

evs transportation in living organisms circulatory system and organs blood and blood vessels circulatory system blood pressure

  1. pulmonary artery

  2. renal artery

  3. coronary artery

  4. carotid artery

Show answer
Correct Option: A
Explanation:

Pulmonary artery and the Pulmonary vein are a set of blood vessels that are related to the lungs. The Pulmonary artery carries deoxygenated blood from the right ventricle to the lungs for oxygenation, this oxygenated blood is carried back to the heart by the Pulmonary vein for systemic circulation i.e. for ​circulation to different parts of the body.

So, the correct option is 'Pulmonary artery'.

Choose the correct answer from the alternatives given.
A vein differs from an artery in having

evs transportation in living organisms circulatory system and organs blood and blood vessels circulatory system blood pressure

  1. strong muscular walls

  2. valves to control the direction of flow of blood towards the heart

  3. valves to control the direction of flow of blood opposite to the heart

  4. narrow lumen

Show answer
Correct Option: B
Explanation:

Veins are less muscular than arteries, contain valves to help keep blood flowing in the right direction, towards the heart. They carry deoxygenated blood from tissues back to the heart. 

So, the correct option is 'valves to control the direction of flow of blood towards the heart'.

Choose the correct answer from the alternatives given.
Water enters capillaries on the venule side as a result of:

evs transportation in living organisms circulatory system and organs blood and blood vessels circulatory system blood pressure

  1. higher red blood cell concentration on this side

  2. increased blood pressure on this side

  3. an osmotic pressure gradient

  4. active transport from tissue fluid

Show answer
Correct Option: C
Explanation:

  • Materials, including oxygen, carbon dioxide, amino acids, sugars, and water, are exchanged between the blood and tissue fluid within blood vessels known as capillaries.
  • Blood pressure and osmotic pressure control the pressure in a capillary. Blood pressure, caused by the heart’s beating, is higher at the arterial end of the capillary and causes water to exit at that point.
  • On the other hand, blood pressure is weak by the time blood reaches the venous end of the capillary, and osmotic pressure becomes higher, causing water to enter at that end.
So, the correct option is 'An osmotic pressure gradient'.

Which of the following is the bodys largest blood vessel?

evs transportation in living organisms circulatory system and organs blood and blood vessels circulatory system blood pressure

  1. Aorta

  2. Capillaries

  3. Pulmonary vein

  4. Heart

Show answer
Correct Option: A
Explanation:

Aorta is the largest artery present in the body. It originates from the left ventricle and extends down to the abdomen. The aorta distributes oxygenated blood to all parts of the body.

So, the correct option is 'Aorta'.

The right side of the heart

  1. Pumps blood to the rest of the body

  2. Receives blood from the rest of the body

  3. Receives blood from the lungs

  4. None of the above

Show answer
Correct Option: B
Explanation:
The right side of our heart receives oxygen-poor blood from our veins and pumps it to your lungs, where the blood picks up oxygen and gets rid of carbon dioxide. The left side of our heart receives oxygen-rich blood from our lungs and pumps it through our arteries to the rest of our body.
So, the correct option is 'Receives blood from the rest of the body'.

Human heart represents

evs circulation of blood circulatory system and organs blood and blood vessels transportation in living organisms role of receptors in the mouth types of teeth

  1. Double circulation

  2. Systemic circulation

  3. Pulmonary circulation

  4. None of the above

Show answer
Correct Option: A
Explanation:

The human heart allows the complete separation of the deoxygenated and oxygenated blood. It has four chambers, the upper two atria and the lower two ventricles. The right side chambers (right atrium and right ventricle) are concerned with the deoxygenated blood. The right atrium receives the deoxygenated blood from the body and the right ventricle pumps it to the lungs. This is the pulmonary circulation. It completes when the left side chamber of the left atrium receives it. So, the left side chambers are concerned with oxygenated blood. The left ventricle then transports it to the rest of the body in the systemic circulation. So, the pulmonary and the systemic circulation maintained by the human heart constitute the double circulation of the blood.

Hence, the correct answer is 'Double circulation'

In the human body, the blood transports

evs circulation of blood circulatory system and organs blood and blood vessels transportation in living organisms role of receptors in the mouth types of teeth

  1. Oxygen

  2. Nutrients

  3. Carbon dioxide

  4. All of the above

Show answer
Correct Option: D
Explanation:
The human circulatory system consists of a muscular four-chambered heart, a network of closed branching blood vessels and blood, the fluid which is circulated. Blood is a special connective tissue consisting of a fluid matrix, plasma, and formed elements. It is pumped by the heart to all over the body. In the human body, the blood transports oxygen, nutrients and carbon dioxide.
So, the correct answer is 'All of the above'.
