List the differences between the hearts of vertebrates that live in water and the hearts of vertebrates that live on land. List the similarities.

Answers

Answer: All vertebrates have circulatory systems based on a common plan, and so vertebrate systems show much less variety than do those of invertebrates. Although it is impossible to trace the evolution of the circulatory system by using fossils (because blood vessels do not fossilize as do bones and teeth), it is possible to theorize on its evolution by studying different groups of vertebrates and their developing embryos. Many of the variations from the common plan are related to the different requirements of living in water and on land.

Explanation:

Since all the vertebrae‘s are in different environments they have to adapt to there surrounding so a cougar won’t have a heart in the same place as a fish

Which statement best describes the human respiratory system? A) It is composed of a network of moist passageways that permit air to flow from the external environment to the lungs. B) Each cell of the human body is in direct contact with the external environment, and gas exchange occurs by diffusion. C) The external body surface is kept moist to allow for gas exchange. D) Gases diffuse across membranes on both the external and internal surfaces of the body.

Answers

Answer:

A) It is composed of a network of moist passageways that permit air to flow from the external environment to the lungs.

Explanation:

The correct statement that describes the RESPIRATORY SYSTEM of human being is option A which states that, It is composed of a network of moist passageways that permit air to flow from the external environment to the lungs.

The sequence of processes leading to the release of energy in living cells is called respiration. The most complex respiratory system is found in mammals ( human beings). This involves the following:

the intake and absorption of oxygen from the surrounding environment; the transport of oxygen to the individual cells in the body; andusing oxygen to release energy (as Adenosine triphosphate) from energy-rich substances.

Because human beings are exposed to the atmosphere and have dry body coverings. Gaseous exchange cannot occur through their body surfaces, instead they possess respiratory structures to being dry air in contact with moist surfaces within their bodies. These structures includes:

the trachea andthe lungs ( where bronchi and alveoli are located)

TRACHEA or the wind pipe channels the air to the lungs. At the thorax, the trachea into two forming the right and left BRONCHI.

The alveoli is where the gaseous exchange takes place. Tiny blood vessels, called capillaries, are closely wrapped around the outside of the alveoli. This enables oxygen to diffuse across the walls of the alveoli into the blood.

Therefore the correct option that describes the RESPIRATORY SYSTEM of human being is A which states that It is composed of a network of moist passageways that permit air to flow from the external environment to the lungs.

Option B is WRONG because human beings are not unicellular organisms like Amoeba where their gaseous exchange organs are cell membrane or body surfaces.

Option C and D are equally wrong because human beings are not simple animals like amphibians that involves in cutaneous (skin) respiration.
