A carrier could be a person that is infected with a disease and agent but doesn't show any symptoms of it. there is a genetic carrier which is a person or an organism that inherited a trait or mutation through genetics but doesn't show any symptoms
Answer:
The correct answer is - The coronary sinus and superior/inferior vena cava fill the right ventricle and right atrium.
Explanation:
The right chambers of the heart receive the blood from the all over the body except lungs by the vena cava and the coronary sinus. Superior and inferior vena cava carries the blood that has no oxygen in it, from the body to the right atria which ultimately moves right ventricles and finally completes its circuit by reaching the lungs to picking the oxygen again.
On the other hand, the left atrium receives the blood from the pulmonary veins from the lungs that carry oxygen and move to the left ventricle and pump out all over the body.
Thus, the correct answer is - the coronary sinus and superior/inferior vena cava fill the right ventricle.

Explanation:
Answer:
The blood pressure reading corresponds to the pressures systolic / diasoltic (option d).
Explanation:
When the blood pressure measurement is made —with the use of a sphygmomanometer— it shows the pressure in the arteries at a precise moment of the heart's activity. The result can be read in millimeters of mercury (mmHg) and are:
- A first reading corresponds to the transmission of the pressure exerted by the heartbeat, called systolic pressure.
- The second reading is always a lower value, and corresponds to the blood pressure between heartbeats, or diastolic pressure.
These readings are obtained by compressing the territory of an artery with a bracelet and then decompressing it to perceive the turbulent flow that follows decompression. This turbulent flow can be perceived by auscultation, which is called Korotkoff's sounds.
Normal systolic pressure in a young adult is in the range of 100 to 135 mmHg, while the diastolic is between 60 and 85 mmHg.
The other alternatives are not correct:
<em> a- </em><u><em>Diastolic / systolic
.</em></u><em> The first reading always corresponds to the systolic pressure.</em>
<em> b- </em><u><em>Good pressure / bad pressure
</em></u><em>. It identifies more blood pressure disturbances than blood pressure readings.</em>
<em> c- </em><u><em>Upper / lower</em></u><em>
. In medicine, the correct blood pressure reading is systolic/diastolic, so saying upper/lower or maximum/minimum is an error.</em>
A tic is a random or sudden, involuntary, repetitive motor movement or vocalization involving distinct muscle groups. Motor tics can include eye blinking, nose crunching, pulling at clothes or touching others. Vocal tics can include clearing one's throat, expressing simple sounds or uttering curse words or racist terms
