The process of respiration involves the main events listed in the choices below. Which event involves the transfer of oxygen from the air sacs into the blood and the release of carbon dioxide from the blood?

In pea plants, round seed (R) is dominant over wrinkled seed (r). Self-pollination of a pea plant with round seed results in 100% pea plants with round seeds. Generation after generation, this pea plant produces round seeds and no wrinkled seed. What is the genotype of this pea plant?
(a)
Which circuit of the circulatory system provides blood flow between the heart and lungs?
(a)
Type AB blood is inherited when an individual receives the type A allele from one parent and the type B allele from the other parent. Thus, the individual possesses the characteristics of both type A and type B blood. Type AB blood is an example of which non-Mendelian pattern of inheritance?
(a)
The waste product of cellular respiration, carbon dioxide, leaves the cells and enters the bloodstream through what type of blood vessel?
(a)
Which part in the respiratory tract is shared by both the digestive and respiratory systems?
(a)
Once blood has been oxygenated, it is pumped out of the heart by the left ventricle into the _, where it travels to the rest of the body
(a)
When we breathe, we instinctively think of our Lungs and Diaphragm; however, structures of the Upper Respiratory Tract such as the mouth, nose, epiglottis, larynx, and windpipe also have very crucial roles during respiration. If, for example, the epiglottis of an individual is removed, how would it affect the performance of the respiratory system?
The air that enters the Lungs wouldn’t be warmed, humidified and filtered for any debris.
The lungs wouldn’t be able to perform gas exchange if Epiglottis is removed.
The air will enter the Stomach, instead of the Lungs, which can cause problems in the digestive system.
The food an individual eats is more likely to enter the trachea which could cause choking.
In snapdragon plants, the gene for red petals (R) is incompletely dominant to the gene for white petals (r). Individuals that are heterozygous (Rr) have pink petals. A plant with pink petals is crossed with a plant with white petals. What is the chance that the offspring will have red petals?

When you swallow, a characteristic "gulp" sound can be heard. This "gulp" is caused by the epiglottis (a flap of tissue) covering the trachea and guiding food/water down the esophagus during swallowing. Which of the following best describes how the epiglottis is connected to the respiratory system's function?
If food/water goes down the trachea, a blockage to the pathway of air in the respiratory system may occur.
Choking on food occurs when the epiglottis blocks the pathway of air from the bronchi to the bronchioles.
Chocking on food/water occurs when the epiglottis blocks the pathway of air from the nose to the pharynx.
If food/water goes down the esophagus, a blockage to the pathway of air in the respiratory system may occur.
Which of the following is NOT a Mendelian law of inheritance?
In every organism, there is a pair of factors that control the appearance of a particular trait.
The first filial generation does resemble either parent. Therefore, no allele is dominant over the other.
During gamete formation, the pair of factors segregates or separates from each other.
During fertilization, the genes come together again to form new combinations.
There are three different alleles—A, B and O—that determine a person’s blood type. Six different genotypes are possible, and they result in four different blood types. What are the possible genotypes of a person with blood type A?
AA and AB
AA and OO
AA and BO
AA and AO
What is the correct path through the circulatory system which describes the passage of blood originating in the left leg?
Vena cava → left atrium → right atrium → lungs → left ventricle → right ventricle → aorta
Vena cava → right atrium → left atrium → lungs → right ventricle → left ventricle → aorta
Vena cava → left atrium → left ventricle → lungs → right atrium → right ventricle → aorta
Vena cava → right atrium → right ventricle → lungs → left atrium → left ventricle → aorta
In pea plants, round seed is dominant over wrinkled. A pea plant with a genotype of Rr will physically express the seed shape as round. This scenario where one trait conceals the presence of another trait for the same characteristic is explained by which Mendelian law?
Law of Dominance
Law of Segregation
Law of Independent Assortment
Law of Incomplete Dominance
When our skin is pierced, we see a red liquid oozing out of the wound; however, we have learned during classes that the blood is composed of different components, specifically, Erythrocytes, Leukocytes, Platelets, and Plasma. If, for some reason, the blood component “Leukocytes” is removed from the blood, what effect would it have on the blood?
The Blood will not flow and not be a “liquid” because it is the liquid component of the blood.
The Blood will lose its ability to transport oxygen and carbon dioxide throughout the body.
The Blood will lose its ability to stop bleeding as it is the component of blood that seals broken blood vessels.
The Blood will lose its ability to protect your body from infections and foreign bodies.
Which chambers of the heart receive and pump un-oxygenated blood?
I. Right atrium
II. Right ventricle
III. Left atrium

In pea plants, yellow seed color is dominant to green seed color. When a homozygous recessive plant (yy) was crossed with a homozygous dominant plant (YY), an offspring with a heterozygous genotype was produced. What is the seed color of the offspring?

The human heart is a muscular organ that pumps blood throughout the body through the blood vessels of the circulatory system.

Asthma occurs when the airways to the lungs become too narrow. How would the circulatory and respiratory systems be affected by asthma? (Choose two answers)
The respiratory system would be over-delivering oxygen to the lungs because the person would be breathing too rapidly.
The respiratory system would have difficulty delivering enough oxygen to the lungs because the airways are not wide enough.
The circulatory system would have a significantly reduced supply of oxygen in the blood, causing oxygen delivery to cells to be reduced.
The circulatory system would have a significantly reduced supply of oxygen in the blood, causing oxygen delivery to cells to increase.
