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 three main parts of a eukaryotic cell is:
-the cell membrane
-the cytoplasm
-the nucleus
Answer:
Arteries at at a higher pressure than veins.
Explanation:
Arteries receive blood after the heart beats, putting them at a higher pressure. They are also thicker than veins as well.
I am thinking the rock that forms from lava that cools quickly is D) Obsidian.
I believe high doses of stimulants can influence driving capabilities by inducing dizziness, panic reactions and hallucinations. Stimulants are substances that can affect a person's mood, often giving the user extra energy and a stronger sense of well-being. They can range from legal substances such as nicotine and caffeine to illegal drugs like cocaine and methamphetamine.
