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'.

Choose the correct answer from the alternatives given.
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'.

Choose the correct answer from the alternatives given.
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 heart is slightly tilted towards the 

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

  1. Right side

  2. Not tilted at all

  3. Left side

  4. Upper side

Show answer
Correct Option: C
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. The heart is mesodermal in origin. It is situated in the thoracic cavity, in between the two lungs. The heart is slightly tilted towards the left side because the right lung is larger than the left lung. This condition provides the heart with enough space to function properly and pump blood efficiently to different parts of the body.

So, the correct answer is 'Left side'.

If the systolic pressure is 120 mm Hg and diastolic pressure is 80 mm Hg, the pulse pressure is ____.

biology human body and organ system blood pressure circulatory system transportation in animal and plants

  1. 120 x 80 = 9600 mm Hg

  2. 120 + 80 = 200 mm Hg

  3. 120-80 = 40 mm Hg

  4. $\frac {120}{80}$ = 1.5 mm Hg

Show answer
Correct Option: C
Explanation:
The pulse pressure can be defined as the difference between the diastolic and systolic pressure of an individual’s heart. If the normal diastolic and systolic pressure of the adult human heart is 120 mm Hg and 80 mm Hg, respectively then the pulse pressure is 120 - 80 = 40 mm Hg.
Thus, the correct answer is '120-80 = 40 mm Hg.'

Which one of the following statements is correct regarding blood pressure?

biology human body and organ system blood pressure circulatory system transportation in animal and plants

  1. 130/90 mm Hg is considered high and requires treatment.

  2. 100/55 mm Hg is considered an ideal blood pressure.

  3. 105/50 mm Hg makes one very active.

  4. 190/110 mm Hg may harm vital organs like brain and kidney.

Show answer
Correct Option: D
Explanation:
The blood pressure above 140/90 mm Hg is considered a high blood pressure and recurrent such values of an individual’s blood pressure can indicate hypertension. Blood pressure with more than values 190/110 mm Hg can have disastrous effects on the kidney and the brain.
Thus, the correct answer is '190/110 mm Hg may harm vital organs like brain and kidney.'
