<span>Superior and inferior vena cava enters the right atrium which is pumped by the tricuspid valve to the right ventricle and to the pulmonary valve to the pulmonary artery then to the lungs from the lungs back thru the pulmonary veins entering the left atrium pumped by the mitral valve to the left ventricle to the aortic valve to the aorta.
The circulatory system is important in meeting the needs of all cells in the body because it offers means of transport by which cells obtain the materials needed to live and function.</span>
Answer:
Carbon stored in plants reaches the atmosphere via cellular respiration. Cellular respiration is the set of metabolic reactions that allows plants to convert the energy from nutrients into ATP (adenosine triphosphate) and then release the waste products. The energy from the glucose molecules is broken down into ATP. Water and carbon dioxide are also required to convert the nutrients into ATP. In our case, carbon and oxygen are waste products so they are released into the atmosphere via the pores underneath the leaf of a plant or tree.
Answer:
Covering organs within trunk cavities
Lining trunk cavities
Explanation:
Serous membranes are layers of tissue that protect the organs. They prevent the organs from getting damage from friction which can occur as they rub against the cavity walls.
Serous membranes have two layers, the visceral layer and the parietal layer. The visceral layer covers the organs while the parietal layer covers or lines the cavity walls. In between these two layers, you will find a gap or cavity filled with serous fluid.
They cover organs like the heart, lungs, blood vessels (some of them at least), testes and other organs found in the abdominal cavity.
