Question 3

Many older individuals feel faint from low blood flow to the brain if they stand up too quickly after lying down.What is the most reasonable explanation for how this problem develops?

Accepted Answer

As people age, the muscles in the arteries and arterioles lose elasticity and become less able to constrict quickly, resulting in a delay in maintaining appropriate blood pressure when changing positions. This can lead to temporary decreased blood flow to the brain and cause individuals to feel faint or dizzy.

Question 4

Hemoglobin,like many other oxygen-binding pigments,contains the metallic element ________.

Accepted Answer

The answer of Hemoglobin,like many other oxygen-binding pigments,contains the metallic...

Question 5

In addition to ethical consideration,artificially increasing the quantity of red blood cells is dangerous;some athletes have suffered ________ after taking drugs like EPO.

Accepted Answer

Artificially increasing the quantity of red blood cells can cause high blood pressure, heart attack, and blood vessel rupture, as stated in the sentence. Option A, nausea, vomiting, and dehydration may occur due to other reasons as well. Option B, difficulty perspiring and subsequent heatstroke, is not directly related to red blood cell count. Option C, decreased muscle mass, is not a known side effect of red blood cell-boosting drugs like EPO.

Question 9

What status would you assign to an individual whose resting blood pressure was consistently 137/78?

Accepted Answer

A resting blood pressure consistently at 137/78 falls into the prehypertensive range, which means that the individual is at an increased risk of developing hypertension in the future. It is not low or hypotensive, nor is it ideal. It is not high or fully developed hypertension as that would require a higher systolic blood pressure reading.

Question 10

Numerous body systems deal with the various physiological issues that living organisms face;the internal transport of oxygen,carbon dioxide,nutrients,hormones,and dissolved wastes is the responsibility of the ________ system.

Accepted Answer

The answer of Numerous body systems deal with the various...

Question 11

Although blood plasma carries many electrolytes,nutrients,and other components,the vast majority of plasma is made of ________.

Accepted Answer

The answer of Although blood plasma carries many electrolytes,nutrients,and other...

Question 12

Where is hemoglobin expected to release oxygen?

Accepted Answer

Hemoglobin is expected to release oxygen near body cells that are undergoing cellular respiration, as the cells require oxygen for their metabolic processes. Hemoglobin picks up oxygen from the lungs and transports it to the body tissues, where it is released.

Question 13

Because of the low pressure and flow rates,the blood in veins may spontaneously clot,as shown below.If the blood clot were to break free it could move to the lungs,causing the life-threatening condition known as ________.

Accepted Answer

The answer of Because of the low pressure and flow...

Question 14

The energy required to pump the blood through the systemic circuit is provided by the force generated when the ________ contracts.

Accepted Answer

The answer of The energy required to pump the blood...

Question 15

Terrestrial vertebrates use an enclosed internal lung to respire because it helps to control fluid loss,but fish have no such constraints and exchange their gases using pairs of external ________.

Accepted Answer

The answer of Terrestrial vertebrates use an enclosed internal lung...

Question 16

The lungs of organism A and organism B have surface areas of 1 cm² and 0.5 cm² per kg body weight,respectively.It would be a reasonable hypothesis that the more metabolically active organism is ________.

Accepted Answer

The answer of The lungs of organism A and organism...

Question 17

Human blood appears red because its most abundant cells contain the red pigment ________.

Accepted Answer

The answer of Human blood appears red because its most...

Question 18

Bubbles slowly form in a glass of cold water as it warms because the solubility of dissolved gases is inversely proportional to the ________ of a solution.

Accepted Answer

The answer of Bubbles slowly form in a glass of...

Question 19

Why do larger animals depend on an internal transport system (like the circulatory system in mammals)to distribute oxygen when small organisms get along fine without one?

Accepted Answer

Diffusion is an efficient means of transport for small distances but becomes impractically slow over larger distances. In larger animals, the distances that oxygen would need to diffuse to reach all cells are too great for diffusion alone to supply cells with oxygen efficiently. An internal transport system, like the circulatory system, moves oxygen close to cells, reducing the diffusion distance and ensuring adequate oxygen supply.

Question 20
