A relatively small blood pressure gradient is generally insufficient to move blood through the veins under given conditions, thus venous return must be facilitated by valves within veins and two "pumps." ... As skeletal muscles contract, veins are squeezed to help propel the blood toward the heart.
Answer:
The most appropriate tissue to join the pubic symphysis -that provides resistance to pressure and stretch during childbirth- is fibrocartilage.
Explanation:
Options for this question are:
- <em>A. Fibrocartilage.</em>
- <em>B. Elastic cartlage.</em>
- <em>C. Bone.</em>
- <em>D. Hyaline cartilage.</em>
Fibrocartilage is made up of dense connective tissue rich in type I collagen fibers, hyaluronic acid and proteoglycans, which give it resistance to stretching and pressure.
Some ligaments are formed by fibrocartilage, in addition to the intervertebral discs and the junction of the pubic symphysis, allowing a certain degree of mobility to the associated structures due to their semi-elastic properties.
Hyaline cartilage, also made up of connective tissue, is less resistant than fibrocartilage.
Bone cannot form this junction, because it would not allow the relative mobility of the joint.
The elastic cartilage allows for stretching but not the strength needed to join the pubic symphysis.

This statement <span>''All systems should aim to achieve 99.999-percent up time''</span> is false.
In reality, all systems should aim to achieve an up time of 99.99%
The different between 0.99 and 0.9999 might not seem a lot but if we actually calculate the percentage points it represents and the amount with which we need to improve efficiently, it almost becomes impossible to reach 99.9999% up time.
