infIdentify flexor digitorum profundus in the right upper limb and the ulnar vein that is immediately superficial to it on its medial surface. What is the correct order of veins that blood flows through to reach the heart from the right flexor digitorum profundus and the right ulnar vein

The upper region of the body veins carries blood that has no oxygen to the heart through superior vena cava and the lower part of the blood with no oxygen will transfer to the heart with the help of superior vena cava.

In Right hand:

At first, blood in the palmar region or distal end of the arm deoxygenated blood from this side will go to the following manner -

right ulnar vein - to the right Axillary vein - to the right subclavian vein - Right internal jugular vein - right brachiocephalic vein and finally it reaches the superior vena cava of the heart.

The same pathway will take place on the left side of the upper region of the body.

the solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. this process is called passive transport or facilitated diffusion, and does not require energy.
