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>
Answer:
It would affect the functionality of the other levels including the organism
Explanation:
The level of biological organization is a hierarchical step consisting of how a multicellular organism forms. According to this level of organization, CELLS are the simplest unit of life and the collection of cells with a similar function is termed TISSUE. Tissues form ORGANS, organs form ORGAN SYSTEMS and finally, a collection of all the systems in the body forms the ORGANISM.
Based on this, one would observe that each level is related to the next in such a way that one forms from the other. Hence, if one of the levels in the biological organization will not perform its function properly, the other levels will be affected. For example, if the kidney cells do not perform it's function, it would affect the functionality of the kidney tissues, kidney organ, the excretory system, and the organism at large.
Answer:
The human genome contains around 20,687 protein-coding genes. Different genes or instructions are read at different times in different cells in response to the requirements of our bodies. Each cell contains two sets of genes, one from your mother and one from your father.
