Beginning with the Superior Vena Cava (SVC) & Inferior Vena Cava (IVC) and ending with the aorta, explain the path that blood takes through the heart and lungs before returning to the body.

The Blood leaves the heart through the pulmonic and into the pulmonary artery and then to the lungs. Blood also leaves the heart through the aortic valve, into the aorta and to the body. This process results in blood flowing through the heart,lungs and body...

Fact if the circulatory or respiratory system were to fail, the other would fail as well, leading to death without medical intervention.  Explain why failure of the circulatory system would cause failure of the respiratory system & Explain why failure of the respiratory system would cause failure of the circulatory system.

Failure of the respiratory system would cause failure of the circulatory system because the respiratory system helps you breath and with you not breathing it would cause the circulatory system to fail because the breathing makes the blood flow through the circulatory system.

MAVERICK [17]

Answer:

The correct answer is option (d) "both b and c".

Explanation:

Experimental model organisms used in scientific investigations have to fulfill certain criteria in order to be useful in the laboratory. Two of the desired characteristics are being able to reproduce quickly and with enough number of offspring in order to study genetic behaviors. <em>Arabidopsis thaliana</em> characteristics of being able to reproduce in 8–10 weeks and producing thousands of offspring per plant (because it can produce thousands of seeds) makes it a model flowering plant for experimental studies.
