goes to the lungs, and then re-enters the heart; Deoxygenated blood leaves through the right ventricle through the pulmonary artery. From the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
<em>The function of the excretory system is </em><em>to remove waste from the body, or any unnecessary materials not kept by storage functions. It is important because it helps maintain homeostasis within organisms</em>
<em>Organs that this system includes are </em><em>the skin, the kidneys, the large intestines, the liver, and the lungs.</em>
Answer:
A contractor who hired two sub-contractors to help work on the house would be most like to osteoblast.
Explanation:
Osteoblasts are cells that build bone, just like contractors build a house. They are cells capable of synthesizing the bone matrix, allowing the formation and growth of bone.
As bone-forming cells, osteoblasts have a large number of mitochondria and a developed Golgi apparatus. They can multiply until they are covered by the bone matrix, becoming known as osteocytes.
The other options are not correct because:
- <em>Osteogenic
: related to bone.</em>
- <em>Osteocycle
: bone cell in its mature shape.</em>
- <em>Osteococlast : cells capable of remodeling the bone, breaking it and allowing the action of the osteoblasts.</em>
