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

Arterial blood pressure in human beings

  1. 120 and 80 mm Hg

  2. 150 and 100 mm Hg

  3. 50 and 100mm Hg

  4. None of the above

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Normal resting blood pressure or arterial blood pressure for an adult human being is about 120/80 mm Hg. Blood pressure is summarized by two measurements, systolic and diastolic, which depend on whether the heart muscle is contracting (systole) or relaxed between beats (diastole).

So, the correct answer is option A.

Normal blood pressure of human being must be

  1. 140/80mmHg

  2. 160/100mmHg

  3. 120/80mmHg

  4. 140/90mmHg

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Blood pressure is the pressure applied on the wall of the arteries and veins. The systolic phase applies greater pressure than the diastolic phase. Normal blood pressure of human being must be 120/80mmHg.

So, the correct answer is option C.

  2. $80$
  3. $100$
  4. $120$
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The diastolic blood pressure measures the pressure in the arteries between heartbeats (when the heart muscle is resting between beats and refilling with blood). A normal diastolic blood pressure is 80mm of Hg.

So, the correct answer is option B.

Which one of the following is a matching pair of a certain body feature and it's value / count in a normal human adult?

  1. Urea - 5-10 mg/100 ml of blood

  2. Blood sugar (fasting) - 70-100 mg/100 ml

  3. Total blood volume - 5-6 ml

  4. ESR in Wintrobe method - 9-15 mm in males and 20-34 mm in females

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
Normal human adult blood should contain between 6 to 20 mg of urea nitrogen per 100 ml (6–20 mg/dl) of blood.
The most commonly used screening tests are determination of the fasting blood glucose level and the blood glucose level tested two hours after a meal. The normal fasting blood sugar content is 70-110 mg per 100 ml of blood.
A typical adult has a blood volume of approximately 5 liters, with females generally having less blood volume than males. Blood volume is regulated by the kidneys.
Results from your ESR rate test will be reported in the distance in millimeters (mm) red blood cells have descended in one hour (hr). The normal range is 0-22 mm/hr for men and 0-29 mm/hr for women.

In a normal adult, BP is

  1. 100/80 mm of Hg

  2. 120/80 mm of Hg

  3. 100/120 mm of Hg

  4. 80/120 mm of Hg

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The instrument used for measuring blood pressure is known as sphygmomanometer. The blood pressure is measured in mm of Hg (millimetres of mercury) and recorded with systolic number first followed by diastolic. In a normal adult, BP is 120/80 mm Hg.

So, the correct answer is '120/80 mm of Hg.

The value of diastolic blood pressure is

  1. 120 mm Hg

  2. 80 mm Hg

  3. 120/80 mm Hg

  4. 40 mm Hg

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
There are two components of blood pressure, systolic and diastolic blood pressure.
  • Systolic pressure is the pressure in blood vessels or the force of blood against the wall of arteries when the ventricles pump out blood into them. It is about 120 mm Hg.
  • Diastolic pressure is the pressure or the force of blood against the wall of arteries when the heart is relaxing and getting refilled with blood. It is about 80 mm Hg.
So, the correct answer is '80 mm Hg'.
Multiple choice biology human body and organ system blood pressure circulatory system transportation in animal and plants

Choose the correct answer from the alternatives given.
Normal blood pressure of a- healthy person is:

  1. 120/100

  2. 110/90

  3. 120/80

  4. 120/90

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

  • Blood pressure is the pressure which is exerted by blood against the wall of the arteries. 
  • The average pressure produced in the ventricles when they contract and the blood is pumped into the aorta and the pulmonary artery is known as the systolic pressure, it is equal to the pressure exerted by a column of 120 mm of mercury. 
  • The average pressure produced in the ventricles when they relax and are filled with blood is known as the diastolic pressure, it is about 80 mm of mercury. Hence the value of blood pressure in an adult is about 120/80.
  • The blood pressure is measured by an instrument known as the sphygmomanometer.
So, the correct option is '120/80'.

Maximum prescribed limit of $Zn$ in drinking water is:

  1. 1 ppm

  2. 10 ppm

  3. 4 ppm

  4. 5 ppm

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
$\Rightarrow$  Zinc is one of the important trace elements that play a vital role in the physiological and metabolic process of many organisms. Nevertheless, higher concentrations of zinc can be toxic to the organism. 
$\Rightarrow$  It plays an important role in protein synthesis and is a metal which shows fairly low concentration in surface water due to its restricted mobility from the place of rock weathering or from the natural sources. 
$\Rightarrow$  According to the standards maximum prescribed limit of $Zn$ in drinking water is $5\,ppm$

Tissue grafting or organ transplant in between the genetically dissimilar individuals of the same species is called

  1. Allogarft

  2. Xenograft

  3. Isograft

  4. Autograft

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

  • Transplantation of cells, tissue grafting or organ transplant in between the genetically nonidentical individuals of the same species is called as allotransplant or Allograft.  
  • A graft is the transplantation of an organ or tissue to a different location, with the goal of replacing a missing or damaged organ or tissue. 
  • Grafts are typically moved without their attachments to the circulatory system and must reestablish these, in addition to the other connections and interactions with their new surrounding tissues. 

So, the correct answer is "Allograft".
