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>
Valves, they are like flaps of muscle that keeps the blood in its place util its ready to be pumped along.
They work on the premise of a fluid interacting with a turbine
Answer:
spherules
Explanation:
Like histoplasmosis, coccidioidomycosis is acquired by the inhaling fungal spores.
<u>Arthrospores are formed by the hyphal fragmentation in this case. Once in body, fungus differentiates into the spherules which are filled with the endospores. </u>
Most of the C. immitis infections are self-limiting and asymptomati. The endospores are transported in blood, disseminating infection and thus leading to formation of granulomatous lesions on face and nose. I
<u>Thus, spherule is a thick-walled spherical structure which encloses the endospores and occurring in parasitic form of the fungi of genus Coccidioides.</u>
The correct answer is (B) chemosynthesis and marine snow are the two ways that organisms on the bottom of deep sea food chains acquire energy.
What is the meaning of chemosynthesis and marine show?
Chemosynthesis is the utilization of energy supplied by inorganic chemical processes to make food in bacteria and other organisms. To generate a sugar, all chemosynthetic organisms require energy provided by chemical processes, although various species employ different methods.
Marine snow is a shower of biological particles that falls from the upper ocean to the deep sea. Marine snow refers to biological material that descends from higher in the water column. Some flakes fall for several weeks before reaching the ocean floor.
