The circulatory or cardiovascular system's ability to deliver oxygen throughout the body depends on proper functioning of the respiratory system. The interactions between the cardiovascular and respiratory systems are best demonstrated by following the path of a red blood cell starting in the heart and traveling through the lungs.
A red blood cell that has just returned from delivering oxygen and that has brought back carbon dioxide would be in the right upper chamber of the heart or in the right atrium. When the atrium contracts, the cell is pumped into the right lower chamber of the heart, or the right ventricle. When that ventricle contracts, the red blood cell is pumped out of the heart through the pulmonary artery to the lungs.
In the lungs, the red blood cell enters tiny blood vessels that come into close contact with the walls of the alveoli air sacs of the lungs. The carbon dioxide in the red blood cell passes through the walls into the alveoli while the oxygen in the alveoli air passes into the red blood cell. The red blood cell then returns to the heart via the pulmonary vein.
From the pulmonary vein, the red blood cell enters the left atrium of the heart and then the left ventricle. The part of the heart muscle powering the left ventricle is very strong because it has to push the blood out to the whole body. The red blood cell is pumped out of the left ventricle via the aorta artery and eventually reaches the capillaries leading to the individual cells. There the cells absorb the oxygen from the red blood cell and pass on their waste carbon dioxide. The red blood cell returns to the right atrium of the heart via the veins to complete the cycle.
These circulatory and respiratory system interactions are ones that humans and higher animals such as mammals and birds share and that represent one of the basic functions of their bodies. Only when these two systems work and interact properly can the human or animal carry out other functions such as looking for food or reproducing.
Im not sure how to answer this since there were no choices given but I will answer by telling you what nuclear fusion is...
so basically nuclear fusion is the merging or combining of 2 isotopes, typically isotopes of hydrogen, under conditions of extreme temperature and pressure thus resulting in the release of massive amounts of energy. I think the answer to your question would be new types of electricity because the heat emitted from the reaction could be turned into electricity by using its steam. This is what happens in nuclear reactors
i hop this answers your question
According to the question, the width of a pin is 0.001m and the width of a red blood cell is 6-8 μm.
Width of pin in μm = 1000μm.
So approximately 1000/8 red blood cells can fit which is equal to 125 RBCs.
Answer: 125 RBCs
Solution:
Dualists view the mind and the body as two fundamental different “things”, equally real and independent of each other. Cartesian thought, or substance dualism, maintains that the mind and body are two different substances, the non-physical and the physical, and a causal relationship is assumed to exist between them. Physicalism, on the other hand, is the idea that everything that exists is either physical or totally dependent of and determined by physical items. Hence, all mental states are fundamentally physical states. In the current study we investigated to what degree Swedish university students’ beliefs in mind-body dualism is explained by the importance they attach to personal values. A self-report inventory was used to measure their beliefs and values. Students who held stronger dualistic beliefs attach less importance to the power value (i.e., the effort to achieve social status, prestige, and control or dominance over people and resources). This finding shows that the strength in laypeople’s beliefs in dualism is partially explained by the importance they attach to personal values
