Specialized tissue on the wall between the atria. Electrical impulses pass from the pacemaker (SA node) through the _______ and the atrioventricular bundle (bundle of His) toward the ventricles.atrium (pl. atria)One of two upper chambers of the heart.capillary<span>Smallest blood vessel. Materials pass to and from the bloodstream through the thin walls. They have walls that are only one endothelial cell in thickness. This delicate, microscopic vessel carries nutrient-rich, oxygenated blood from the arteries and arterioles to the body cells. There, the nutrients are burned in the presence of oxygen (catabolism) to release energy.
At the same time, waste products such as carbon dioxide and water pass out of the cells and into these blood vessels. Waste-filled blood then flows back to the heart in small venues, which combine to form larger vessels called veins.</span>carbon dioxideGas (waste) released by body cells, transported via veins to the heart, and then to the lungs for exhalation.coronary arteriesBlood vessels that branch from the aorta and carry oxygen-rich blood to the heart muscle.deoxygenated bloodBlood that is oxygen-poor.diastole<span>Relaxation phase of the heartbeat.</span>
The circulatory system takes the carbon dioxide from the cells to the lungs and the respiratory system expels ir.
Photosynthesis is the process through which plants use sunlight and carbon dioxide to make food to sustain themselves. Cellular Respiration is when cells use oxygen and water to create a food source for the cell. The formula for photosynthesis is the same for cellular respiration except it's backwards. Hope this helps.
Answer:
Although wind makes up about 8% of total U.S. electricity generating capacity, wind generators provided a smaller share (5%) of total U.S. electricity generation in 2016 because wind turbines have relatively low capacity factors.
