Question
Ultrafiltration, the movement of fluid from capillaries into and out interstitial spaces relies on the following forces:
a) The outward directed forces are generated by higher concentration of solutes in the blood
b) The inward directed hydrostatic forces are generated by the lymphatic system
c) The inward directed hydrostatic forces are generated by pressure on the blood generated by the heart
d) The inward directed forces are generated by higher concentration of solutes and proteins in the blood
a) The outward directed forces are generated by higher concentration of solutes in the blood
b) The inward directed hydrostatic forces are generated by the lymphatic system
c) The inward directed hydrostatic forces are generated by pressure on the blood generated by the heart
d) The inward directed forces are generated by higher concentration of solutes and proteins in the blood
Explanation / Answer
Ultrafiltration, the movement of fluid from capillaries into and out interstitial spaces relies on the inward directed hydrostatic forces which are generated by pressure on the blood generated by the heart. It is known as hydrostatic pressure which can be defined of the pressure of any fluid enclosed in a space. This enables the fuid out of the capillaries and into the interstitial spaces. Hence, the correct option is c.
