Answer:

Question: Two requirements for gas exchange which are accomplished by the gills in a fish include:

1. Water flowing in opposite directions across the gill lamellae for gas exchange, in other words, respiration is experienced by the fish.

2. The fish allows water through its mouth, then forces the water to drain through the gills supporting gill lamellae, and enhancing gas exchange.

Question: How does their structure help to satisfy these requirements?

1. The rows of gill filaments with numerous folds through diffusion makes sure oxygen from the water moves from a place of more concentration to the blood of the fish which has less concentration causing the removal of carbon dioxide.

2. The large surface area of the gill means it has to maximize the low percentage of dissolved oxygen in the water compared to the higher percentage of oxygen in the air makes it possible for water to pass through the mouth and empty through the gills after the mouth is closed.

The ______ is a fossa formed by the ilium, ischium and pubis which with the femoral head forms the _______ joint.
Setler [38]

The acetabulum is a fossa formed by the ilium, ischium and pubis which with the femoral head forms the coxal joint.

The acetabulum is made up of the three bones that make up the coxal bone (hip bone).

The ischium, which offers the lower and side limits to the acetabulum, makes up somewhat more than two-fifths of the structure.

Less than two-fifths of the acetabulum's structure is provided by the ilium, which also serves as the top limit of the joint.

The pubis, which is close to the midline, forms the remainder.

The acetabulofemoral joint (art. coxae), also known as the coxal joint, is the joint between the head of the femur and the acetabulum of the pelvis.

Its main job is to support the weight of the body in both static (such as while standing) and dynamic (such as when walking or running) postures.

The ability of body systems to increase their function, given the need to adapt, is known as the The ability of body systems to
Whitepunk [10]

Answer:

The ability of body systems to increase their function, given the need to adapt, is known as the <u>physiologic reserve.</u>

Explanation:

The ability of body systems to increase their function if the need to adapt arises is known as a physiological reserve. Frequently, this term is used to refer to the operating limits of a particular physiological system when under stress. When this stress exceeds the ability of a particular organ or system to compensate for it, organ failure occurs. Adaptation achieves its highest efficiency when changes are generated gradually/progressively rather than abruptly. In aging, this reserve is diminished and therefore the ability of the organs to adapt to stress is lower, that is, the ability to adapt is reduced in extreme ages.
