Answer: c) central vein.
Explanation:
The liver is an organ that is present both in humans and in vertebrate animals. It secretes the bile, essential for the digestion of fats, and it also has many other functions, including the synthesis of plasma proteins, storage of vitamins and glycogen and detoxifying function. It is responsible for removing various substances from the blood that may be harmful to the body, including alcohol, making them harmless.
The liver is divided by the sickle cell ligament into two main lobes, right and left. <u>There are two other smaller lobes, the square lobe and the caudate lobe</u>.
The hepatic triads are triangular areas located at the angles of the hepatic lobules, made up of a lax conjunctive stroma. <u>They contain a branch of the hepatic artery</u> (that irrigates the liver<u>),</u> <u>a hepatic portail vein</u> (a thick blood vessel that carries blood from the gastrointestinal tract and spleen to the liver so that nutrients are metabolized<u>)</u> and <u>a bile duct</u> (transports bile into the small intestine). Therefore, it does not contain a central vein.
<u>Answer</u>:
The term for the ability of muscles to be slightly contracted at all times to be ready to act is Muscle tone.
<u>Explanation</u>:
Regular partial contraction of the muscle or can be said as its resistance power to stretching during the resting phase. It helps in maintaining the posture of the body. The muscle tone occurs due to the hypotonia. This happens as the muscles depends upon the motor nerve signals which can be disrupted at the brain level, spinal cord or may be due to damage of muscle nerve. It can be measured with the stiffness which acts as a resistance to that of the passive movement.

Considering the definition of volume, the volume of a cube with a side length of 3 centimeters is 3 cm³.
<h3>Volume</h3>
Volume is a measure of the space occupied by an object in three-dimensional space.
In other words, volume of a geometric figure is defined as the amount of space occupied by the object or figure in three-dimensional space. Volume is measured in cubic units.
The volume of a cube is equal to the measure of its side to the cube. That is to say:
Volume = side x side x side = side³
<h3>This case</h3>
In this case, you have a cube with a side length of 3 centimeters. Replacing in the definition of volume:
Volume= 3 centimeters× 3 centimeters× 3 centimeters
Solving:
<u><em>Volume= 3 cm³</em></u>
Finally, the volume of a cube with a side length of 3 centimeters is 3 cm³.
