Answer:
The correct answer is - 7 to 10 inches.
Explanation:
The infant and placenta of the mother is connected with the umbilical cord which is need to be cut to separate the infant from placenta. Umbilical cord carries important nutrients and blood to the infant from the mother.
Clamping the umbilical cord is oldest technique which is necessary to separate the baby from the placenta. The closest clamp should be approximately 7 inches to maximum of 10 inches to the body of infant.
Thus, the correct answer is - 7 to 10 inches.
Answer: The standard ECG has 12 leads. Six of the leads are considered “limb leads” because they are placed on the arms and/or legs of the individual. The other six leads are considered “precordial leads” because they are placed on the torso (precordium). The six limb leads are called lead I, II, III, aVL, aVR and aVF.

The muscles that are impaired from muscle contraction are Tibialis anterior & extensor digitorum longus.
Humans have a muscle called the tibialis anterior that arises from the upper two-thirds of the lateral portion of the tibia and inserts into the first metatarsal and medial cuneiform bones of the foot. It causes the foot to dorsiflex and invert. Near the shin is where this muscle is primarily found.
It is located on the lateral side of the tibia and is tendinous below and thick and fleshy above. The anterior tibial vessels and deep peroneal nerve are covered by the tibialis anterior in the upper leg.
The feather-like muscle of the front compartment of the leg is called the extendor digitorum longus. The tibialis anterior, extensor hallucis longus, and fibularis tertius muscles are also located in this compartment in addition to the EDL muscle.

Answer:
The answer to the question: velocity of blood is relatively constant as blood flows from the aorta towards the capillaries, would be, B: False.
Explanation:
One way to figure this one out is knowing that the velocity of the blood as it flows through the aorta, comes from the pumping strength of the heart. However, as the blood starts traversing the length of the different arteries, arterioles, and finally reached the capillaries, it encounter two things; first, the speed with which it was originally launched by the heart into the aorta, has already diminished as it moves away from the heart. Second, blood will encounter a series of barriers, not the least of which is resistance from the blood vessels themselves, that will lower the speed with which it will reach the capillares. And this is just as well, as capillaries are much more fragile than arteries themselves, their purpose actually being to serve as exchange points between the cardiovascular system and the different tissues of the body. Their structure is much thinner, and thus needs less speed, in order for exchanges to take place. This is why it is false.
