A portal system Multiple Choice includes a functional end artery that makes an arterial anastomosis. is one in which circulation
to a large organ involves only one artery and one main (portal) vein. is one in which multiple arteries converge on one organ or body region. is a simple circulatory system with an areriovenous anastomosis. is one in which blood flows through two capillary beds before being sent back to the heart.
is one in which blood flows through two capillary beds before being sent back to the heart.
Explanation:
A portal system can be defined as a system of blood vessels having a capillary network at each end, meaning that the blood vessel starts and ends in capillaries, before finding its way back to the heart. The blood draining through the capillary bed flows via the larger vessel to supply the blood to the another structure's capillary bed.
A portal system is one in which blood flows through two capillary beds before being sent back to the heart.
Explanation:
A portal system consists of one afferent arteriole that anastomoses and gives several capillaries and an efferent arteriole that also anastomoses and gives capillaries, these two capillaries are connected, forming a big capillary bed. The blood flows, fist through the afferent arteriole, then to the capillary bed of this arteriole, and from there it goes, to the capillary bed of the efferent arteriole to end in the efferent arteriole that leads the blood to the heart.
An electronic cardiac monitor is the preferred method for assessing heart rate during chest compressions. While a person is performing chest compressions on a patient, he or she is hooked up to the electronic cardiac monitor so that the doctor can see exactly how fast the patient's heart is pumping blood. Cardiac monitoring is the best method do assess this.
Explanation: Magnetic force, attraction or repulsion that arises between electrically charged particles because of their motion. The magnetic force between two moving charges may be described as the effect exerted upon either charge by a magnetic field created by the other.
