Answer:Through the Left ventricle
Explanation:
.
Anatomically, the left ventricle empty directly into the aorta.  Therefore the probe will pass through the aortic valve to exist in left ventricle. 
The left ventricle pumps oxygenated blood out of the heart through the aorta into the systemic circulation. Consequently, there must be a closed link between the chamber which stores and empty the blood (left Ventricle), and the vessel which conveys blood to the target areas (Aorta) in the systemic circulation.

Answer:
Red blood cell is a blood cell which contains hemoglobin necessary for the transport of oxygen in blood from one part of body to another part. 
Explanation:
These are the most abundant cells in the blood and are developed from liver and yolk sac in fetus while from the bone marrow in children and adults. Red blood cells (RBCs), also called erythrocytes, are cells that circulate in the blood and carry oxygen throughout the body. These cells are produced in the bone marrow and are released into the bloodstream as they mature. RBCs typically make up about 40% of the blood volume. The normal RBC range for men is 4.7 to 6.1 million cells per microliter (mcL). The normal RBC range for women who aren't pregnant is 4.2 to 5.4 million mcL. The normal RBC range for children is 4.0 to 5.5 million mc. 
 
        
                    
             
        
        
        
Answer:
Explanation:Bioaccumulation occurs when toxins build up - or accumulate - in a food chain. The animals at the top of the food chain are affected most severely. This is what happens: Small amounts of toxic substances - often pesticides or pollution from human activity - are absorbed by plants.while biomagnification is the process by which toxins are passed from one trophic level to the next (and thereby increase in concentration) within a food web. ... dissolve into the fatty tissues of living organisms.
 
        
             
        
        
        
<span>The answer is that there will be no change.
 The cardiac output is the volume of blood pumped by the heart per unit time. 
Multiplying the stroke volume and the heart rate gives you the cardiac output. The cardiac output for a person at rest is approximately 5L per minute.</span>
